Mr. Robles has two kinds of fruit in his basket. The ratio of apples to oranges in the basket is 3:4.
If there are 9 apples, how many pieces of fruit are in his basket?
OA. 38
OB. 8
OC. 12
OD. 21

answer is "c" - 12

Step-by-step explanation:

apples = 3x ( 3 of x )

orange = 4x (4 of x)

if 3x = 9

x= 9/3= 3

then 4x = 4(3)= 12!!

There may be other ways to solve  this but this is one I guess : )

21 is the answer

Step-by-step explanation:

i leave the calculator work to you.

7. diameter 4 miles, circumference 4π miles

8. radius 0.2 miles, circumference 0.4π miles

[this is a bad problem because the actual radius of a car on the track is less than 0.2 miles so the answer is less than 0.4π miles]

9. radius 6 feet, circumference 12π feet

10. diameter 14 cm, circumference 14π cm

11. diameter 4.8 feet, circumference 4.8π feet
