One year i had 30 ap environmental science students and the next year i had 50 environmental students, what percentage did the population of apes students grow by?

If you want to find by how much percent something increased, take the final value and divide it by the initial value. When you divide 50 by 30, you get 5/3, which can be written as 1.666(repeating). Then, you subtract 1 from the answer and multiply by 100. So, the population of APES students grew by 66.66%

Hello!

To find this, we divide our 50 by 30.

50/30=1.6666666

We need to subtract one to find how much of the 30 increased.

.6666666

We can round this to a percent

66.67%

I hope this helps!

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet
