The farmer needed to fertilize 520 apple trees. He fertilized 20 trees per day for 10 days. After that, he had to finish the rest in
8 days. How many apple trees did he have to fertilize per day
in the rest of the time?
apple trees per day

40 is the answer

Step-by-step explanation:

Farmer fertilized 20  trees per day for 10 days=20*10=200

total trees- fertilized tree=leftover trees

520-200=left over trees

320=left over trees

per day fertilized tree=left over trees /8

per day fertilized trees=320/8

per day fertilized trees=40

step-by-step explanation:

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
