Okay. Let's make a proportion for this. So we can do 21/3=x/60. Let's multiply cross way. So 21 x 60 is 1260. We multiply 3 by x to get 3x. So our equation will be 3x=1260. We can isolate the equation by 3, and 1260 divided by 3 is 420. So x=420. We then have to convert into feet. So 420 divided by 12 is 35. So it would be 35 feet. Therefore, the machine can make 35feet of ribbon in a hour.
Answer:
- C. Change the length to side CB to 8 feet
Step-by-step explanation:
<u>Corresponding sides of similar triangles should have same ratio:</u>
- PR/AC = PQ/AB = RQ/CB
- 7.5/6 = 5/4 = 10/CB
- 10/CB = 1.25
- CB = 10/1.25
- CB = 8 feet
Correct choice is C
