Suppose that 4% of the 500 athlete in a major meet have actually taken performance enhancing drugs, and all athletes are given the drug test

20 athletes have taken performance-enhancing drugs.

Step-by-step explanation:

Assuming that you want to find the number of athletes that have taken drugs, multiply 4% (0.04) by 500.

4%=4/100=1/25

1/25*500=20, 20 athletes have taken performance-enhancing drugs.

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.

r and t.

both are 64 degrees.
