It has been estimated that one million people are added to the world's population every 4.5 days. Use this rate to answer the following question. How many babies to the nearest million are added each year?

81 million

Step-by-step explanation:

In one year there is 365 days, if you divide 365/4.5 the answer is 81.1. And every 4.5 days add 1 million people, then you multiply

81.1*1 000 000 = 81 100 000

approaching to the nearest million, 81 million of babies are added each year.

2500

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
