Well, you would do 5+3 which is 8. Then divide 160 and 8. The answer is 20. So now multiply 3 and 20. the answer is 60. Now multiply 5 and 20. the answer is 100. 100+60 is 160. So that checks out. As a result, the 5 would be the boys so the 5 and 20 are 100. So there are 100 boys in the grade.

HURRY I NEED HELP!!!!!!!!!!!!! A circle is drawn within a square as shown.
Anton [14]
The width of the square is 7 cm. This is also the diameter of the circle.

To find the area of the square, you do 7², which is 49 cm². 

To find the area of a circle, you do πr².

The radius is half the diameter, so it's 7 ÷ 2, which is 3.5 cm.

π3.5² ≈ 38.4845100065 cm².

The shaded region is the area of the square minus the area of the circle.  

49 - 38.4845100065 = <span>10.5154899935, but because you're using 3.14 to approximate pi, the closest answer is 10.54 cm</span>².

The answer is 10.54 cm².

Which pair of ratios makes a proportion?
Nana76 [90]

Answer:

  • D. 1/4 and 9/36

Step-by-step explanation:

If two ratios make a proportion then it can be shown as:

  • a/b = c/d ⇒ ad = bc

Let's verify the answer choices with this method

A. 1/4 and 5/25

  • 1*25 = 4*5
  • 25 = 20, incorrect, not a proportion

B. 1/4 and 7/24

  • 1*24 = 4*7
  • 24 = 28, incorrect, not a proportion

C. 1/4 and 10/48

  • 1*48 = 4*10
  • 48 = 40, incorrect, not a proportion

D. 1/4 and 9/36

  • 1*36 = 4*9
  • 36 = 36, correct, this is a proportion
