Answer:

Step-by-step explanation:

The sum of the angles in a triangle is 180.  So for the triangle on the right:

36 + 84 + x = 180

x = 60

The two angles in the corner add up to 90.  So:

60 + y = 90

y = 30

Finally, for the triangle on the left:

30 + 86 + z = 180

z = 64

Answer:

sinA=15/17 and cosA=8/17

Step-by-step explanation:

sine is opposite side over hypotenuse and cosine is adjacent side over hypotenuse

Answer:

sin A = [tex]\frac{15} {17} [/tex] and cos A =[tex] \frac{8}{17}[/tex]

Step-by-step explanation:

We are given a right angled triangle and we are to determine the ratios for sin A and cos A.

Sin is the ratio of perpendicular/hypotenuse while cos is the ratio of base/hypotenuse.

With respect to angle A, base = 8, perpendicular = 15 and hypotenuse = 17.

Therefore, [tex]sin A = \frac{15}{17}[/tex] and [tex]cos A = \frac{8}{17}[/tex].

Answer:

[tex]x=\frac{9}{2}[/tex] and [tex]y=27[/tex]

Step-by-step explanation:

A system of linear equations is a set of (linear) equations that have more than one unknown. The unknowns appear in several of the equations, but not necessarily in all of them. What these equations do is relate the unknowns to each other.

We need to find the solution of the follow equations:

[tex]16x-18=2y[/tex] and [tex]4x+9=y[/tex]

First, we divided by 2 the equation [tex]16x-18=2y[/tex]

We obtain [tex]8x-9=y[/tex]

Equating both equations

[tex]8x-9=4x+9[/tex]

Let's clear x

[tex]8x-4x=9+9\\4x=18\\x=\frac{18}{4} \\x=\frac{9}{2}[/tex]

Substituting the value of x in the second equation

[tex]4(\frac{9}{2}) +9=y\\y=\frac{36}{2} +9=18+9\\y=27[/tex]

.

Answer:

Option 4 is the correct option.

Step-by-step explanation:

We need to solve the expression 2x(x+2)(x-3)

Multiplying the terms with each other we get,

[tex]2x(x+2)(x-3)\\=2x(x^2 -3x+2x-6)\\=2x(x^2 -x -6)\\=2x^3 -2x^2 -12x[/tex]

Option 4 is the correct option.

It will cost $440 to carpet the room.

To find the cost of carpeting the room, we need to calculate the area of the room in square yards.

First, let's convert the dimensions of the room from feet to yards:

15 ft = 5 yd (since 1 yd = 3 ft, 15 ft = 5 yd)

12 ft = 4 yd

Next, calculate the area of the room in square yards:

Area = Length x Width = 5 yd x 4 yd = 20 square yards

Finally, multiply the area by the cost per square yard:

Cost = Area x Price

= 20 x $22/square yard

= $440

bearing in mind that the sum of all interior angles in a polygon is

180(n - 2)    n = number of sides in the polygon

a DECAgon, DECA=10, has 10 sides, and thus the sum of all its interior angles is 180(10 - 8) = 1440.

[tex]\bf 156+135+147+160+116+150+150.2+119.2+146.6+z=1440 \\\\\\ 1280+z=1440\implies z=1440-1280\implies z=160[/tex]

Final answer:

The angle z in the decagon is calculated by subtracting the sum of the given angles from the total interior angle sum of a decagon, which is 1440°. The measure of angle z is 159.8°.

Explanation:

In geometry, the sum of the interior angles of an n-sided polygon is given by the formula (n - 2) × 180°. For a decagon, which is a 10-sided polygon, this sum is (10 - 2) × 180° = 8 × 180° = 1440°. To find the measure of the unknown angle z in the decagon with the given angle measurements, we can subtract the sum of the known angles from this total.

First, let's add up the given angles: 156° + 135° + 147° + 160° + 116° + 150° + 150.2° + 119.2° + 146.6° = 1280.2°. Now, subtract that sum from the total sum of the angles for a decagon: 1440° - 1280.2° = 159.8°. Therefore, the measure of angle z is 159.8°.

The percentage of the discount given on television is 17.72%.

The percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.

Given that a $79 television is on sale for $65. The percentage of the discount will be calculated as:-

Discount% = ( Original price - Discounted price ) / Original price

Discount% = ( 79 - 65 ) / 79

Discount% = 17.72%

Answer:

19.2 grams of medicine should be received by 120 pound woman

Step-by-step explanation:

150 pound woman receive medicine = 24 grams, we need to find how many grams of medicine should 120 pound women receive?

Solution:

150 pound woman receive medicine = 24 grams

1 pound woman receive medicine = 24 /150

120 pound woman receive medicine = (24 /150) * 120 = 19.2 grams.

So, 19.2 grams of medicine should be received by 120 pound woman.

Final answer:

An exponent, or a power, is mathematical shorthand for repeated multiplications. It is used to multiply a number by itself a certain number of times.

Explanation:

An exponent, or a power, is mathematical shorthand for repeated multiplications. For example, the exponent "2" means to multiply the base for that exponent by itself (in the example here, the base is "5").

5² = 5 x 5 = 25

The exponent is "2" and the base is the number "5." This expression (multiplying a number by itself) is also called a square. Any number raised to the power of 2 is being squared. Any number raised to the power of 3 is being cubed.

Answer:

if it has two real repeated solutions then t=-9/8

if it has two real distinct solutions then t>-9/28

Step-by-step explanation:

Given:

tx^2+3x-7=0

Also above equation has two real solutions

Now what can deduced about the value of t?

For any quadratic equation "ax^2 +bx +c=0" the solution is given by the quadratic formula

x= [tex]\frac{-b+/-\sqrt{b^{2}-4ac } }{2a}[/tex]

The part under the square root i.e b^2 - 4ac is called the discriminant and it decides whether the equation will have 1 solution, 2 solution or no solution.

if discriminant is negative, i.e. <0 then equation will have no real solution

if discriminant is zero, i.e. =0 then equation will have two repeated real solution

if discriminant is positive, i.e >0 then equation will have two real distinct solution

As given equation has two real solutions:

if they are distinct then

b^2-4ac>0

Putting values of a=t, b=3, c=-7 in above we get,

9+28t>0

28t>-9

t>-9/28

if they are repeated then

b^2-4ac=0

Putting values of a=t, b=3, c=-7 in above we get,

9+28t=0

28t=-9

t=-9/28!

Answer:

$97.75

Step-by-step explanation:

since its 15% off, the price would be 85% of its original price.

85/100 x $115 = $97.75

Jeanine paid $97.75 for the hiking boots after receiving a 15% discount on the regular price of $115.00. The discount was calculated by converting the percentage to a decimal and multiplying it by the regular price, then subtracting it from the regular price.

Jeanine bought hiking boots with a 15% discount off the regular price of $115.00. To calculate how much Jeanine paid for the hiking boots, we first need to find the amount of the discount. The discount amount is calculated as 15% of the regular price.

The calculation for the discount is as follows:

Convert the percentage to a decimal by dividing by 100: 15% / 100 = 0.15.

Multiply the regular price by the decimal: $115.00  imes 0.15 = $17.25.

Subtract the discount from the regular price: $115.00 - $17.25 = $97.75.

Thus, Jeanine paid $97.75 for the hiking boots.

I'm only a few Brainliests away from ranking up, so one would be much appreciated. Thank you!

Answer:

193.8

Step-by-step explanation:

the measure of those two angles equals 180 since it forms a line

so you add up both angles and set that equal to 180.

(I'll use x as the variable but it's still the same answer)

5x-3+9+x=180

combine like terms

6x+6=180

subtract 6

6x=174

then divide by 6

x=29

To find the value of angle H in a triangle, you subtract the sum of the other two angles from 180. This is based on the triangle angle theorems which state that the sum of the angles in a triangle always equals 180 degrees.

In triangle angle theorems, the sum of the angles of a triangle always add up to 180 degrees. If you need to find the value of angle H in your triangle, you'll need to know the measures of the other two angles. For example, if one angle measures 60 degrees and the other measures 50 degrees, you would subtract the sum of these two angles from 180 to find the value of angle H.

Sum of angles in triangle = 180 degrees

So, Angle H = 180 - (60 + 50) = 70 degrees

1. 5k-9=-3k+7

Add 9 to both sides: 5k-9+9=-3k+7+9

5k=-3k+16

Add 3k to both sides: 5k+3k=-3k+16+3k

(You are adding 3 and 9 instead of subtracting them because in the equation, they are negative numbers and you have to do the opposite operation to get rid of them.)

8k=16

Divide both sides by 8: 8k/8=16/8

k=2

2. 2(w-3)+5=3w-2

Use the distributive property: 2*w-2*3+5=3w-2

2w-6+5=3w-2

Combine like terms: 2w-1=3w-2

Add 1 to both sides: 2w-1+1=3w-2+1

2w=3w-1

Subtract 3w from both sides: 2w-3w=3w-1-3w

-w=-1

Divide both sides by -1: -w/-1=-1/-1

w=1

3. 8t+9=7t+6

Subtract 9 from both sides: 8t+9-9=7t+6-9

8t=7t-3

Subtract 7t from both sides: 8t-7t=7t-3-7t

Answer:

The 3rd sequence could not be described by the following recursive definition tn+1 = tn + 6

Step-by-step explanation:

* Lets revise the recursive formula

1. Determine if the sequence is arithmetic (Do you add, or subtract, the

  same amount from one term to the next?)

2. Find the common difference. (The number you add or subtract.)

3. Create a recursive formula by stating the first term, and then stating

   the formula to be the previous term plus the common difference.

   a1 = first term;

   an+1= an + d

- Where:

# a1 = the first term in the sequence

# an = the nth term in the sequence  

# an+1 = the term after the nth term  

# n = the term number

# d = the common difference.

* Now lets solve the problem

∵ tn+1 = tn + 6

∴ d = 6 ⇒ common difference

- The 1st sequence 5 , 11 , 17 , 23 , 29 , .... has common difference 6

- The 2nd sequence 0 , 6 , 12 , 18 , 24 , .... has common difference 6

- The 3rd sequence 6 , 9 , 12 , 15 , 18 , .... has common difference 3

∴ This sequence could not be described by the following recursive

  definition tn+1 = tn + 6

* The 3rd sequence could not be described by the following recursive

  definition tn+1 = tn + 6

Simplify [tex]\bold{-30x-12y+6\left(6x-2y\right): \ 6x-24y}[/tex]

= 6x - 24y

Mordancy.

For this case we must simplify the following expression:

[tex]-3 (10x + 4y) +6 (6x-2y)[/tex]

We apply distributive property to the terms of the parenthesis, taking into account that:

[tex]- * - = \\- * + = -[/tex]

So, we have:

[tex]-30x-12y + 36x-12y =[/tex]

We add similar terms:

[tex]-30x-12y + 36x-12y =[/tex]

Equal signs are added and the same sign is placed, while different signs are subtracted and the sign of the major is placed:

[tex]6x-24y[/tex]

ANswer:

[tex]6x-24y[/tex]

Step-by-step explanation:

3- -5 equals 8. 8/2 equals 4. 4 plus -5=-1. so the x coordinate=-1.

2- -7=5. 5/2=2.5. 2.5+-5=2.5. so the y coordinate= 2.5. so the full set of coordinates= -1,-2.5

For this case we have that by definition, the circumference of a circle is given by:

[tex]C = \pi * d[/tex]

Where:

d: It is the diameter of the circle

We have as data that:

[tex]C = 6 \pi[/tex]

So:

[tex]6 \pi = \pi * d[/tex]

Thus, the diameter of the circle is 6, therefore the radius is 3.

The area of a circle is given by:

[tex]A = \pi * r ^ 2[/tex]

Where:

r: It is the radius of the circle

[tex]A = \pi * 3 ^ 2\\A = 9 \pi[/tex]

Answer:

Option B

Answer:

9π in. ²

Step-by-step explanation:

The circumference of a circle is diameter times pi.

To find the area of a circle, you multiply the radius by itself, and the product by pi.

Diameter (6 in.) divided by two equals the radius (3 in.).

3 x 3 = 9 in.²

Then multiply by pi to get, 9π in.²
