Answer:

x=15

Step-by-step explanation:

Supplementary angles are two angles that equal the sum of 180 degrees.

Take 4x and 8x and make it equal to 180

4x+8x=180

Add like terms:

12x=180

Divide:

x=15

To check:

Plug in 15 to both expressions

4(15)=60

8(15)=120

Add them up and they equal 180 degrees

Hope this helps! :)

Answer:   The answer is 60, 45, 20, then 5.

Step-by-step explanation:

The variance would increase the bigger the numberr because there is more data. Lets says that the 5 women have a range of 1 and 10 with a meam with a 5. The data separating the mean and the top range is 5. But lets says that the range for the women is 1 and 80, with a mean of 40. The difference in the mean and the top range is 40. 40>5 because there is simply more data. Therefore higher variance.

Answer:

Given : The high school stadium contains a track that surrounds a soccer field. The soccer field is 100 yards long and 70 yards wide.

The school decided to cover the semicircles with grass to create a space for stretching and other activities.

To Find: area of one of the semicircles at either end of the track

How many square yards of grass will the school need to cover the entire circle?

Solution:

Diameter of semicircle = 70 yards

Radius of semicircle = 70/2 = 35 yards

Area of semicircle at one end = (1/2)πr²

= (1/2)(22/7)35²

= 1,925 sq yards

area of one of the semicircles at either end of the track = 1,925 sq yards

square yards of grass will the school need to cover the entire circle

= 2 x   1,925

= 3850 sq yards

distance around one of the semicircles at either end of the soccer field = πr  = (22/7) 35 = 110 yards

distance around the inner lane of the track  = 100 + 100 + 110 + 110

= 420 yards

Answer: I believe  that A is the function to this problem

Step-by-step explanation:

Answer:

1 - A is not a function

2 - B is not a function

3 - A is not a function

X can have only 1 value

for example 2B features x=5 where f(x) = -4 but also 1. That means it's not a function

Answer:

6.75 miles

Step-by-step explanation:

20.25 / 3 = 6.75

Answer:

A) 217.75 sales tax

B)281.40 he will pay on the loan

C)$3849.15 he will pay including total cost, interest, and tax

Step-by-step explanation:

A)

To find sales tax, multiply the price by its percentage. 6.5% in decimal is 0.065. 3350x0.065=217.75 for its sales tax.

B)

This is the same for loan.

3350x0.084=281.40 he will pay for loan.

C)

Now add it all up. 3350+217.75+281.40=3849.15

Answer:

The correct answers are:

a. $217.75!

b. $281.40!

c. $3,849.15!

Step-by-step explanation:

a. Find the sales tax by multiplying the price by its percentage (6.5%, 0.065 in decimal form)

3,350 x 0.065=217.75

so the sales tax is $217.75

b. This is the same as finding tax. Find the loan by multiplying the original price by the percentage (8.4%, 0.084 in decimal form).

3,350 x 0.084 = 281.40

so the loan is $281.40

c. This time, sum the original price with both the loan and sales tax.

3,350 + 217.75+ 281.40= 3849.15

so the total cost for the new tractor is $3,849.15

So there you have it. You have your answers right here. Hope this helps! Be sure to mark this as brainliest!
