A PLANE IS FLYING AT 30,000 FEET AND NEEDS TO RISE TO 36,000 FEET IN 2 STAGES.
IN STAGE 1, IT RISES 5% OF ITS INITIAL ALTITUDE OF 30,000 FEET..
IN STAGE 2, IT RISES AT A RATE OF 140 FEET PER MINUTE. HOW MANY MINUTES DOES IT TAKE FOR THE PLANE TO RISE TO 36,000 FEET IN STAGE 2

you divide the cost ($15) by the quantity (6) to get your questions answer. the yo-yo costs $2.50. hope this : )!

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
