If an airplane’s speed is 300 miles per hour, what is it’s speed in feet per second? a. 60 feet per second b. 440 feet per second c. 26,400 feet per second d. 1,584,000 feet per second

B. 440 feet per second

Step-by-step explanation:

What you need to do is first convert miles to feet and then hours to seconds. Then you should be able to get the answer

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2

1^3 + 2^3 + 3^3 +4^3 = (1+2+3+4)^2

step-by-step explanation:

i am only able to answer the first part. i am not sure about the second part. sorry
