Two of the angles in a parallelogram measure 5x° and 7x°. what is the value of x?
Answers
The value of x is 15.
What is parallelogram?"It is a quadrilateral with opposite sides parallel.""The opposite angles of parallelogram are equal. "For given question,
Two of the angles in a parallelogram measure 5x° and 7x°
The measure of an angle opposite to 5x° is also 5x°
Similarly the measure of an angle opposite to 7x° is also 7x°
So, we have the four angles of parallelogram as 5x°, 7x°, 5x°, 7x°
We know, the sum of all angles of quadrilateral is 360°
⇒ 5x° + 7x° + 5x° + 7x° = 360°
⇒ (5 + 7 + 5 + 7) x = 360
⇒ 24x = 360
⇒ x = 15
Therefore, the value of x is 15.

I’m stuck on 5-6. Please help if you could explain the answer also that would be awesome
Answers
i think #6 is Infinitely many
The answer to the first question is "b. one," according to Euclid's First Postulate. The answer to the second question is "c. infinitely many," according to Euclid's Second Postulate. These principles form the foundation of Euclidean geometry.
In Euclidean geometry, there are fundamental postulates and theorems that govern the behavior of lines and angles in triangles. Let's address your questions:
1. How many lines can be drawn through point A perpendicular to segment BC?
Answer: There can be only one line drawn through point A that is perpendicular to segment BC. This follows from Euclid's First Postulate, which states that a straight line can be drawn between any two points. In this case, the straight line from point A to any point on segment BC is unique and perpendicular.
2. How many lines can be drawn through point C perpendicular to segment AB?
Answer: Infinitely many lines can be drawn through point C that are perpendicular to segment AB. This is based on Euclid's Second Postulate, which states that a straight line can be extended infinitely in both directions. So, you can draw as many lines as you like, all of which are perpendicular to segment AB, and they will extend infinitely in both directions.

what is 50/12 in a mixed number
Answers
4 1/6
A mixed fraction is when there is more than 1 whole i.e. 1 3/4
A improper fraction is when there is more than 1 whole i.e. 50/12
As you may have observed, the thing which differentiates a mixed fraction from an improper fraction is that a mixed fraction's numerator is never bigger than it's denominator.
:)
50/12 is an improper fraction,
To convert this into a mixed fraction, we can find out how many times 50 fits in 12: 50/12 = 4.16666
So we know there are 4 wholes, which as twelfths are 48/12;
We can then observe the difference between 50 and 48 is 2 twelfths
So 50/12 as a mixed number/fraction is 4 wholes and 2 twelfths
which can also be written as 4 2/12 and then simplified to 4 1/6

Two vehicles leave new york simultaneously going in inverse headings. one goes at a typical speed of 77 mph and the other at 63 mph.
The relative speed is given as,
S = 77 + 63
S = 140 miles per hour

5x-4(2x+11)=13
solve for x
show all work please
Answers
So multiply -4x2x and -4x11.
5x-8x-44=13
Add all your like terms so 5x+-8x.
-3x-44=13. Now add 44 to both sides.
-3x= 57. Now divide both sides by -3 to get the x by itself.
x=-19
1)distribute the -4 to the numbers within the parenthesis.
5x-8x-44=13
2) next step you combine light terms.
''5x-8x=-3x''
so now you have -3x-44=13
3) add 44 on both sides
and you're left with -3x=57
4) divide both sides by -3 in order to solve for x; x divided by any number is always x, and 57divided by -3 is -19
5) so you're left with [n=-19] as your final answer

Now we solve for b

[tex]\frac{3600}{3000} = \frac{3000b^{4}}{3000}[/tex]

Find the 55th derivative of y = cos(3x).
Answers
Final answer:
The 55th derivative of y = cos(3x) is recognized by repeating the derivative patterns of cosine functions and is found to be -27cos(3x).
Explanation:
The 55th derivative of y = cos(3x) can be found by recognizing that the derivatives of sine and cosine functions repeat every four steps. Considering the pattern cos(x) -> -sin(x) -> -cos(x) -> sin(x) -> cos(x), and that the derivative of cos(3x) is -3sin(3x), we can determine that the pattern repeats every four derivatives with a factor of 3n, where n is the number of times the derivative is taken.
The 55th derivative will be the same as the third derivative in the cycle, but with an iteration count of 55/4, which leaves a remainder of 3, so the 55th derivative will be -27cos(3x).

What is the equation of a line that passes through the point (8, −2) and is parallel to the line whose equation is 3x + 4y = 15? Enter your answer in the box
Answers
Step 1
Find the slope of the given line
we have
[tex]3x+4y=15[/tex]
Isolate the variable y
Subtract [tex]3x[/tex] both sides
[tex]3x+4y-3x=15-3x[/tex]
[tex]4y=-3x+15[/tex]
Divide by [tex]4[/tex] both sides
[tex]y=-\frac{3}{4}x+ \frac{15}{4}[/tex]
the slope of the given line is
[tex]m=-\frac{3}{4}[/tex]
Step 2
Find the equation of the line that passes through the point [tex](8,-2)[/tex] and is parallel to the given line
we know that
if two lines are parallel, then their slopes are equal
The equation of the line into point-slope form is equal to
[tex]y-y1=m(x-x1)[/tex]
we have
[tex]m=-\frac{3}{4}[/tex]
[tex](x1,y1)=(8,-2)[/tex]
substitute in the equation
[tex]y+2=-\frac{3}{4}(x-8)[/tex]
[tex]y=-\frac{3}{4}x+6-2[/tex]
[tex]y=-\frac{3}{4}x+4[/tex] or [tex]3x+4y=16[/tex]

Lets start by saying cookies as the number.
Sum = 2 numbers add together. The answer to the equation. Lik 5+5=10. 10 is the sum.
You only know that Gina has 2 more cookies than Sara.
If Sara has 3 cookies then Gina has 5 cookies. Whats the Sum? 8.
So, you figure out an random big number but, smaller than 68.
Lets do 68 to try now. So you do 68/2 = 34. You remember that Gina has 2 more than Sara. So, 35 cookies for Gina. So, you can guess that Sara has 33 cookies.

The united states has 12,383 miles of coastline. If 0.8% of the coastline is located in Georgia, about how many miles of coastline are in Georgia
Answers
0.8% * 12383
99.064 miles
Answer:
99.064 miles of coastline are in Georgia.
Step-by-step explanation:
Consider the provided information.
The united states has 12,383 miles of coastline and 0.8% of the coastline is located in Georgia.
Now we need to find about how many miles of coastline are in Georgia.
Thus solve this as shown:
0.8% of 12,383
[tex]\frac{0.8}{100} \times 12,383[/tex]
[tex]0.008 \times 12,383[/tex]
[tex]99.064[/tex]
Hence, 99.064 miles of coastline are in Georgia.
the product of three consecutive nonzero integers
Answers
Final answer:
To find the product of three consecutive nonzero integers, multiply the first number by the next two numbers in the sequence.
Explanation:
If the first integer is n, the next will be n+1 and the next to it will be n+2
The product of three consecutive nonzero integers can be calculated using the formula:
n * (n+1) * (n+2)= n(n^2 + 3n+ 2)=n^3 +3n^2 + 2n
where 'n' represents the first integer. For example, if we take 'n' as 2, the three consecutive nonzero integers would be 2, 3, and 4. So, the product would be 2 * 3 * 4 = 24= (2)^3+ 3*(2)^2+ 2*2

Answers
Answer:
Atleast 53
Step-by-step explanation:
We are given that your basketball team has a goal to collect atleast 160 blanket for a shelter.
Team member bought blankets on Monday =42
Team member bought blankets on Wednesday=65
We have to write an inequality and find the number of blankets has to collect on Friday.
Let x be the number of blankets bought by team members on Friday
According to question
[tex]42+65+x \geq 160[/tex]
[tex]107+x \geq 160[/tex]
Subtract 107 on both sides
[tex]107-107+x\geq 160-107[/tex]
[tex]x\geq 53[/tex]
Hence, team members bought atleast 53 blankets on Friday .
