Brock spends 15 minutes walking to
school and 15 minutes walking home
each day. By the end of the school week
(5 days) how many hours has Brock spent
traveling between home and school?

2.5 hours

Step-by-step explanation:

First you add 15+15 which equals 30. Then you do 30x5 and that equals 150. So in minutes it would be 150 minutes, but in house it would be 2 and a half.

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
