Hot air balloons generally defend at a rate of 200 to 400 feet per minute. Six balloons defend 255 feet per minute for 7 minutes. Find the total change in altitude for all 6 balloons

something over 10 so ? /10

step-by-step explanation:

answer: cos [   arcsin (3/5) - arccos (1/2) ] =

step-by-step explanation: × = 3/5 = 0.6--> x = 36.87 and x = 180 - 36.87 = 143.13 deg

cos y = 1/2 --> y = +- 60 deg a. cos (x - y) = cos (143.13 - 60) = cos 83,13  

=

0.12

b. cos (36.87 - 60) = cos (-23.23) = 0.92

how many times greater is the value of 83 than the value 0.083?

= 1000
