Answer:
The equation you should solve to find b is:
Option D. sin 35° / 9 = sin 40° / b
Step-by-step explanation:
m<A=35°
m<B=40°
a=9
b=?
We can use the Law of sines:
sin A / a = sin B / b
Replacing the given values:
sin 35° / 9 = sin 40° / b
This is option D.
Celebrity A has 400 followers on social media and is gaining 75 followers each day. Celebrity B has 1000 followers on social media but is losing 25 followers a day. How many days will it take them to have the same number of followers?
Answer:
The days will it take them to have the same number of followers is:
6 days.Step-by-step explanation:
To solve the proposed exercise, an equation must be made for each one taking into account the information obtained:
Followers Celebrity A = 400 + 75d Followers Celebrity B = 1000 - 25dWhere d is the number of days elapsed. Since you want to identify the day in which they will have the same number of followers, you proceed to match the two equations:
400 + 75d = 1000 - 25dAnd you clear the variable d (remember that those who are adding to one side of equality, go to the other side to subtract and, if they are subtracting to one side of equality, go to add):
400 + 75d = 1000 - 25d 75d + 25d = 1000 - 400 100d = 600 d = 600/100 d = 6 daysa school is sponsoring a comedy show to raise money for charity.for every adult ticket sold the school can donate $4.00 to charity. a total of 408 tickets are sold and 1/2 of them are adult tickets how much money can the school donate
Final answer:
The school can donate $816 to charity from the adult ticket sales of their comedy show, based on the 204 adult tickets sold at $4.00 per ticket.
Explanation:
To find out how much the school can donate, first, determine the number of adult tickets sold. Since half of the 408 tickets are adult tickets, there are 204 adult tickets sold (408 tickets × 1/2 = 204 adult tickets). Next, calculate the total donation from these adult tickets by multiplying the number of adult tickets by the donation per ticket, which is $4.00.
Total Donation = Number of Adult Tickets × Donation per Adult Ticket = 204 × $4.00 = $816.
Therefore, the school can donate $816 to charity from the comedy show ticket sales.
Answer:
$ 816 is donated to charity.
Step-by-step explanation:
408 tickets were sold. 1/2 were adult tickets so
408 * 1/2 = 204 adult tickets were sold.
4 dollars from each adult ticket is donated to charity
204 * 4 =816
$ 816 is donated to charity.
Sixteen students in a drama club want to attend a play. The ticket price is $35 for each student, and the transportation and meals for everyone will cost$960. To pay for the trip, the students design sweatshirts to sell for profit of $19per sweatshirt. If each student sells the same number of sweatshirts, how many sweatshirts must each student sell so that there will be enough money to pay for the entire cost of the trip?
Final answer:
To cover the entire cost of the trip, each student must sell at least 80 sweatshirts.
Explanation:
To find out how many sweatshirts each student must sell, we need to calculate the total cost of the trip and then divide it by the profit per sweatshirt. The total cost of the trip is the sum of the ticket price for each student and the cost of transportation and meals for everyone:
Total Cost = (Ticket Price * Number of Students) + Transportation and Meals Cost
Substituting the given values, we have:
Total Cost = ($35 * 16) + $960
Total Cost = $560 + $960
Total Cost = $1520
Now, we can calculate the number of sweatshirts each student must sell to cover the total cost of the trip:
Number of Sweatshirts = Total Cost / Profit per Sweatshirt
Substituting the given profit per sweatshirt value, we get:
Number of Sweatshirts = $1520 / $19
Number of Sweatshirts = 80
Therefore, each student must sell at least 80 sweatshirts to cover the entire cost of the trip.
Find two numbers the quotient is between 136 divided by 6
Answer:
12 and 136
Step-by-step explanation:
12 divided by 2 is 6, and 136 divided by 2 is equal to 68.
For the two numbers the quotient is between 136 divided by 6 will be 22 and 23.
We may examine the division and take into account the closest whole numbers to the quotient in order to get the two numbers that are the product of 136 divided by 6.
(Rounded to four decimal places) 136 divided by 6 equals 22.6667. 22 and 23 are the whole numbers that are most similar to this quotient.
We may then deduce that the value of the quotient of 136 divided by 6 is between 22 and 23. Accordingly, the outcome of the division of 136 by six will be a number more than or equal to 22 but less than 23. To put it another way, the quotient falls between [22, 23].

Two parallel lines cut by a transversal can create all the following types of angles except
A) alternate interior angles
B) alternate exterior angles
C) corresponding angles
D)complementary angles
The type of angle that is not formed by two parallel lines cut by a transversal is complementary angles. So option (d) is correct.
The intersection of two parallel lines by a transversal forms several types of angles:
1. Alternate Interior Angles: These are angles on opposite sides of the transversal and inside the parallel lines. They are congruent.
2. Alternate Exterior Angles: These are angles on opposite sides of the transversal and outside the parallel lines. They are also congruent.
3. Corresponding Angles: These are angles in the same position at each intersection. They are congruent when the parallel lines are cut by a transversal.
4. Complementary Angles: These are angles whose measures sum up to 90 degrees. They can be formed when a transversal intersects parallel lines, but they are not a specific type of angle formed by this intersection.
Therefore, the type of angle that is not formed by two parallel lines cut by a transversal is D) complementary angles. The other options, A) alternate interior angles, B) alternate exterior angles, and C) corresponding angles, are all formed by this intersection.

Use mathematical induction to prove the statement is true for all positive integers n, or show why it is false.
Base Case: plug in n = 1 (the smallest positive integer)
If n = 1, then 3n-2 = 3*1-2 = 1. Square this and we see that (3n-2)^2 = 1^2 = 1
On the right hand side, plugging in n = 1 leads to...
n*(6n^2-3n-1)/2 = 1*(6*1^2-3*1-1)/2 = 1
Both sides are 1. So that confirms the base case.
-------------------------------
Inductive Step: Assume that
1^2 + 4^2 + 7^2 + ... + (3k-2)^2 = k*(6k^2-3k-1)/2
is a true statement for some positive integer k. If we can show the statement leads to the (k+1)th case being true as well, then we will have sufficiently proven the overall statement to be true by induction.
1^2 + 4^2 + 7^2 + ... + (3k-2)^2 = k*(6k^2-3k-1)/2
1^2 + 4^2 + 7^2 + ... + (3k-2)^2 + (3(k+1)-2)^2 = (k+1)*(6(k+1)^2-3(k+1)-1)/2
k*(6k^2-3k-1)/2 + (3(k+1)-2)^2 = (k+1)*(6(k^2+2k+1)-3(k+1)-1)/2
k*(6k^2-3k-1)/2 + (3k+3-2)^2 = (k+1)*(6k^2+12k+6-3k-3-1)/2
k*(6k^2-3k-1)/2 + (3k+1)^2 = (k+1)*(6k^2+9k+2)/2
k*(6k^2-3k-1)/2 + 9k^2+6k+1 = (k+1)*(6k^2+9k+2)/2
(6k^3-3k^2-k)/2 + 2(9k^2+6k+1)/2 = (k*(6k^2+9k+2)+1(6k^2+9k+2))/2
(6k^3-3k^2-k + 2(9k^2+6k+1))/2 = (6k^3+9k^2+2k+6k^2+9k+2)/2
(6k^3-3k^2-k + 18k^2+12k+2)/2 = (6k^3+9k^2+2k+6k^2+9k+2)/2
(6k^3+15k^2+11k+2)/2 = (6k^3+15k^2+11k+2)/2
Both sides simplify to the same expression, so that proves the (k+1)th case immediately follows from the kth case
That wraps up the inductive step. The full induction proof is done at this point.

For △RST and △UVW, ∠R≅∠U, ST≅VW, and ∠S≅∠v. Explain how you can prove △RST ≅△UVW by ASA
To prove that △RST ≅ △UVW by ASA (Angle-Side-Angle) congruence, we need to show that angle S is congruent to angle U, side ST is congruent to side VW, and angle R is congruent to angle V.
To prove that △RST ≅ △UVW by ASA (Angle-Side-Angle) congruence, we need to show that angle S is congruent to angle U, side ST is congruent to side VW, and angle R is congruent to angle V.
1. Given that ∠R ≅ ∠U, we have the first angle in both triangles congruent.
2. Given that ST ≅ VW, we have the side opposite to the congruent angles congruent in both triangles.
3. Given that ∠S ≅ ∠V, we have the second angle in both triangles congruent.

Final answer:
Triangles △RST and △UVW are congruent by ASA postulate, which states if two angles and the included side of one triangle are congruent to two angles and the included side of another triangle, then the two triangles are congruent.
Explanation:
To prove that triangles △RST and △UVW are congruent by the Angle-Side-Angle (ASA) postulate, we first observe the given congruent parts: ∠R ≅ ∠U, ST ≅ VW, and ∠S ≅ ∠V. Now, by the ASA postulate, if two angles and the included side of one triangle are congruent to two angles and the included side of another triangle, then the two triangles are congruent. We have two pairs of congruent angles: ∠R ≅ ∠U and ∠S ≅ ∠V, and one pair of congruent sides: ST ≅ VW (△RST's side ST is included between ∠R and ∠S, and △UVW's side VW is included between ∠U and ∠V). This satisfies the requirements for the ASA postulate, so we can conclude the triangles are congruent: △RST ≅ △UVW.

22.11 divided by 11?
Final answer:
To find the result of dividing 22.11 by 11, you simply divide 22.11 by 11, yielding an answer of 2.01. This basic division operation demonstrates how to divide a decimal by a whole number.
Explanation:
The question is asking to divide 22.11 by 11. To solve this, you would take the number 22.11 and divide it by 11. Dividing these numbers is straightforward and can be done using long division or a calculator.
Step 1: Place 22.11 under the division bracket and 11 outside of it.
Step 2: Determine how many times 11 fits into 22.11. Since 11 goes into 22 exactly two times, you write 2 above the division bracket, aligned with the last digit of 22.
Step 3: Multiply 2 (the quotient) by 11 (the divisor) to get 22, and subtract this from 22.11, leaving you with a remainder of 0.11.
Step 4: Bring down the next digit (if any), but since we already have no more digits left in 22.11, we look at the remainder. In practical terms for simple school-level math, we can stop here, acknowledging that 11 goes into 22.11 twice without a perfect division due to the decimal.
The actual answer to 22.11 divided by 11 is 2.01.
WHAT IS THE ANSWER TO THIS "q+d=24, .25q+ .10d= 4.95"
Answer:
d=7 and q+0=17
Step-by-step explanation:
I will solve your system by substitution.
(You can also solve this system by elimination.)
d+q=24;0.10d+0.25q=4.95
Step: Solve d+q=24 for d:
d+q+ (−q) =24+(−q) (Add -q to both sides)
d=−q+24
Step: Substitute −q +24 for d in 0.10d+0.25q=4.95:
0.10d+0.25q=4.95
0.10(−q+24)+0.25q=4.95
0.15q+2.4=4.95 (Simplify both sides of the equation)
0.15q+2.4+(−2.4) =4.95+(−2.4) (Add -2.4 to both sides)
0.15q+0=2.55
0.15q+0 /0.15 = 2.55/0.15 (Divide both sides by 0.15)
q+0=17
Step: Substitute 17 for q in d= −q+24:
d= −q+24
d= −17+24
d=7 (Simplify both sides of the equation)

What is 8 3\4% expressed as a fraction?
Answer: The answer is: " [tex]\frac{7}{80}[/tex] " .
_________________________________________________
Step-by-step explanation:
__________________________________________________
Given: " 8 [tex]\frac{3}{4}[/tex] % " ; Convert this to a "fraction" .
__________________________________________________
Start with the: " 8 [tex]\frac{3}{4}[/tex] " portion:
Start with the: " [tex]\frac{3}{4}[/tex] " portion :
Note: " [tex]\frac{3}{4}[/tex] " ;
= 3/4 ;
= 3 ÷ 4 ; {use calculator} ;
= 0.75 .
_________________________________________________
Or; recognize, from experience, that: "3/4" = " 0.75 " .
_________________________________________________
Or: Calculate as follows:
→ " [tex]\frac{3}{4}[/tex] = [tex]\frac{?}{100}[/tex] " ;
→ Solve for the: "(?)" value:
__________________________________________________
Consider the "denominator" portions:
→ " 4 * {what value?} = 100 " ;
→ 100/4 = 100 ÷ 4 = 25 ;
→ So: " 4 * {25} = 100 ;
Now, consider the "numerator" portions:
→ " 3 * {25} = "{?}" ;
→ " 3 * {25} = " 75 " ;
__________________________________________________
Now, we can rewrite the expression;
& replace the "{?}" — with: " 75 " ; as follows:
__________________________________________________
The original expression:
→ " [tex]\frac{3}{4}[/tex] = [tex]\frac{?}{100}[/tex] " ;
Rewrite as:
→ " [tex]\frac{3}{4}[/tex] = [tex]\frac{75}{100}[/tex] " ;
_______________________________________________
Note: " [tex]\frac{75}{100}[/tex] " ;
= 75 / 100 = 75 ÷ 100 ;
→ Use calculator: = 0.75 ;
_______________________________________________
Or: 75 ÷ 100 = ? ;
→ Note: when dividing by "100" ; we take the original value, and move that number backward "2 (two) decimal spaces". We move "backward" because we are "dividing" (not "multiplying") ; and we move 2 (two) decimal spaces because: " 100" has 2 (two) zeros.
→ " 75 ÷ 100 = 75. ÷ 100 = .75 ;
→ Write as: " 0.75.
_______________________________________________
So: " 8 [tex]\frac{3}{4}[/tex] " ;
= 8 + [tex]\frac{3}{4}[/tex] ;
= 8 + 0.75 ;
= 8.75 .
_______________________________________________
So: " 8 [tex]\frac{3}{4}[/tex] % " ;
= 8.75 % ;
_________________________________________
Note that " % " ; refers to parts per hundred; or: "divided by 100" ;
_______________________________________________
→ So: " 8.75 % " ;
= 8.75 / 100 = 8.75 ÷ 100 ;
→ Use calculator; to get: " 0.0875 " .
_______________________________________________
Or: " 8.75 ÷ 100 " ; → As aforementioned, when dividing by "100" ;
we move the decimal point "backward 2 (two) spaces:
→ " 8.75 ÷ 100 = .0875 ;
→ Write as: " 0.0875 " .
_______________________________________________
Now, let us convert this value to a "fraction value" ;
→ We have: " 0.0875 ;
We look at the last consecutive non-zero digits: "875" .
→ How many decimal spaces backward from "875" ; specifically, the digit, "5" ; are there (counting backward; to the actual decimal point)?
→ 0.0875 . → The answer is: "4 (four)" ; which are: 5, 7, 8, and 0 " .
{Refer to digits in "bold font".}.
_______________________________________________
So, this value: " 0.0875 " ;
→ is equal to: " 875 " ÷ { 1 followed by 4 [four] zeros } ;
_______________________________________________
= " 875 ÷ 10000 " ;
= " 875 ÷ 10,000 " ;
_______________________________________________
Using a calculator:
" 875 ÷ 10,000 " = " [tex]\frac{875}{10,000}[/tex] " ;
______________________________________________
= " [tex]\frac{7}{80}[/tex] " .
______________________________________________
The answer is: " [tex]\frac{7}{80}[/tex] " .
______________________________________________
Hope this is helpful to you!
Best wishes to you!

A box is shaped like a cube the box has a length of 1 foot a width of 1 foot and a height of 1 foot what’s the volume of the box
Answer:
1 ft³
Step-by-step explanation:
The formula for the volume of a cube is
Vol. = l³ = l × l × l
If l = 1 ft,
V = 1 ft × 1 ft × 1 ft
V = 1 ft³
The volume of the cube with each side measuring 1 foot is 1 cubic foot, calculated by the formula V = 1 ft × 1 ft × 1 ft or simply V = s³.
The volume of a cube can be determined by multiplying its three dimensions together. In this case, the cube has dimensions of 1 foot in length, 1 foot in width, and 1 foot in height. The formula for the volume of a cube is V = length imes width imes height. Therefore, for a cube with all sides of 1 foot each, the volume is straightforwardly calculated as:
V = 1 ft × 1 ft × 1 ft = 1 cubic foot.
The properties of a cube tell us that all sides are equal, and thus, to find the volume, we can also use the expression V = s³, where s is the length of a side of the cube. Since each side is 1 foot, the volume is indeed 1 cubic foot or 1 ft³. This simple calculation is a great example of how to apply geometric principles to find volume.

Final answer:
To find how many more stamps Rhonda needs to collect to reach her goal, utilize the inequality 335 + d ≥ 575 with d representing the additional stamps needed, resulting in d ≥ 240.
Explanation:
Rhonda's Inequality:
335 + d ≥ 575; d ≥ 240
To determine how many more stamps Rhonda must collect to reach her goal, we set up the inequality 335 + d ≥ 575, where d represents the number of stamps she must collect. By solving this inequality, we find that Rhonda needs to collect at least 240 more stamps to reach her goal.
If the sum of the squares of the legs of a triangle doesn’t equal the square of the hypotenuse, the triangle is not a triangle.
Answer: In a right triangle, the sum of the squares of the two legs equals the square of the hypotenuse. Legs (a and b): the sides of the triangle adjacent to the right angle. They don't need to be the same length in order for this theorem to work.
If the sum of the squares of the legs of a triangle doesn’t equal the square of the hypotenuse, the triangle is not a RIGHT triangle.
Step-by-step explanation:We know that in a right angled triangle the Pythagorean Theorem hold true.
According to Pythagorean Theorem:
If the three sides lengths of a triangle are a,b and c respectively such that:
[tex]c^2=a^2+b^2[/tex]
Then such a triangle is a right triangle with hypotenuse c and other two legs of triangle as a and b.
Hence, the answer is:

(2x-4i)(x+2i)
(2x-4i)(x-2i)
(2x+4i)(x+2i)
(2x-2i)(x+6i)
Answer:
The expression equal to 2x^(2)+8 is:
First option (2x-4i)(x+2i)
Step-by-step explanation:
If we multiply
(2x-4i)(x+2i)=(2x)(x)+(2x)(2i)-(4i)(x)-4i(2i)
(2x-4i)(x+2i)=2x^(1+1)+4xi-4xi-8i^(1+1)
Simplifying:
(2x-4i)(x+2i)=2x^2-8i^2
and i^2=-1, then:
(2x-4i)(x+2i)=2x^2-8(-1)
Multiplying:
(2x-4i)(x+2i)=2x^2+8
To find the expression that is equal to 2x^(2) + 8, simplify each option by expanding the multiplication and then compare it to the original expression.
Explanation:To find the expression that is equal to 2x^(2) + 8, we need to simplify each option by expanding the multiplication and then compare it to the original expression.
Let's simplify each option:
(2x-4i)(x+2i) = 2x^2 - 8 + 4xi + 4xi^2 = 2x^2 - 8 - 4x + 4xi(2x-4i)(x-2i) = 2x^2 - 4xi + 4xi - 8i^2 = 2x^2 + 8(2x+4i)(x+2i) = 2x^2 + 4xi + 4xi + 8i^2 = 2x^2 + 8(2x-2i)(x+6i) = 2x^2 + 12xi - 2xi - 12i^2 = 2x^2 + 8 + 10xiThe expression that is equal to 2x^(2)+8 is (2x-4i)(x-2i).
