The answer is option (B) i.e. The elevator traveled upward at a rate of
ft/sec.
So, we say at time, t = 0, the elevator just starts moving upwards and at time t = 0, the elevator is 90 ft below the ground.
Now, after 15 seconds, the elevator is 20 ft below the ground.
It means, the elevator has covered a distance of 90-20=70 ft in time 15 seconds.
So, speed of elevator moving upwards is:
=
ft/sec
Answer:B or 540 cubic inches.
Step-by-step explanation:
So, if we multiplied all 3 values using the volume formula, we get 600 cubic inches. And if it says 90%, we multiply .9x600 and get 540 cubic inches.
f(5) = <span> -2(5)^2 + 2(5) -3
f(5) = -50 + 10 - 3
f(5) = -43

First your take 55 and divide it by 20 to find out have many feet is equivalent to 1 inch. 2.75 feet is equivalent to 1 inch. then you divide that by 8 to find your 1/8 inch equivalent. 2.75/ 8 is equal to .34 feet per 1/8 inch.
