There are 40 males and 50 females participating in a marathon. What percent of the participants are female?

The answer is [   ]

Step-by-step explanation:

Since both 40 males and 50 females, we add them to get 90 ppl in all. 50 of those 90 are female. Find that ration, 50:90, as a percentage. That would be 55.5% (i think)

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
