A painter charges $15.83 per hour, plus an additional amount for the supplies. If he made $143.72 on a job where he worked 4 hours, how much did the supplies cost?
A.
$35.93
B.
$90.40
C.
$80.40
D.
$63.32

A

Step-by-step explanation: 143.72 divided by 4 is 35.93. If he worked for 4 hours and had a total of 143.72 then you simply have to divided the total cost by hours worked

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

step-by-step explanation:

well if you round, things become much more simple. round 5.95 to 6, 4.25 to 4, and 1.05 to 1. now, add 6+4+1 and that would equal 11. so the items together would equal to about $11.
