45% of the student body at a local high school work part-time. 80% of the students who do not part-time love math whereas only 60% of the students who work part-time love math. What total percentage of the student body love math?

71%

Step-by-step explanation:

I think the easiest way to think of this is to pretend that there are a total of 100 students at the high school, so that means the amount of people who work part time is 45% of 100 = 45 people. If 60% of those students love math, you do 0.6 * 45 = 27 people.

Next, 80% of the students who do not have a part time job (100 - 45 = 55) love math, so 0.8 * 55 = 44 people.

44 + 27 = 71, so the percent is 71/100 = 71%.

let me know if any part of that doesn't make sense

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
