Compare the following pair of numbers a and b in three ways. a. find the ratio of a to b. b. find the ratio of b to a. c. complete the sentence: a is percent of b. a=160 and b=420

a.8:21

b.21:8

c.38.095%

Step-by-step explanation:

We are given that A=160 and B=420

a.We have to find the ratio of A and B

We divide A by B then we get ratio of A and B

Hence, the ratio of A and B=8:21

b.We have to find the ratio of B and A

We divide B by A then we get ratio of B and A'

Hence, the ratio of B and A=21:8

C.Let x percent of B is A

Hence, A is 38.095% of B.

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
