Answer:

16. D. 180 inches

17. A. 1/20 pound

18. D. (2,6)

19. A. 2/8

20. D. 22

Step-by-step explanation:

16. every 5 feet is 60 inches there is 15 feet because 1 yard=3 feet so 60*3=180

17. when you round it upwards you would have 30/40 and 32/40 so it would be 2/40 and then simply 1/20 so therefore it would be 1/20

18. The cost of milk is 3 so that would be (3,y) then every gallon would be y so (3,1)

19. You know this because when you plug in all the other numbers none of the rest of them work but A so therefore it must be A

20. So first you would multiply 2*2*2*2=8 Then you would divide 172/8=22. So therefore your answer would be 22

2 concentric circles have radii 2cm and 3cm respectively, calculate the ratio of their areas​
VikaD [51]

Answer:For the first circle the radius is 2cm and for the second circle the radius is 3cm,by taking the ratio of their areas:

πr^2:πR^2

π cancels out and we are left with only r^2:R^2

r=2cm and R=3cm

Therefore r^2:R^2=2^2:3^2

=4:9

The answer is 4:9

<h3>Answer:  11/12</h3>

============================================================

Explanation:

3/4 = 9/12 after multiplying top and bottom by 3

1/3 = 4/12 after multiplying top and bottom by 4

When combining the fractions 3/4 and 1/3, we get,

3/4 + 1/3 = 9/12 + 4/12 = (9+4)/12 = 13/12

Let's convert that result into a mixed number

13/12 = (12+1)/12

13/12 = 12/12 + 1/12

13/12 = 1 + 1/12

13/12 = 1 & 1/12

Adam and Brian have collectively eaten 1 full pizza plus an additional 1/12 of the second pizza. This leaves 11/12 of the second pizza for Christine to eat. Notice how the fractions part 1/12 and 11/12 add to 12/12 = 1.
