Each floor is 10 feet so that is 240

since the elevator travels 5 ft/sec you will need to find the time to travel the 240 feet

so decide 240 by 5 and you get 48 feet :)

Each floor is 10 feet so that is 240 feet. The elevator travels 5 ft/sec, so to find the time to travel the 240 feet, divide. 240÷5=48 sec.

How are u supposed to find the area only with the circumference?
seraphim [82]

Answer:

We can find the radius from circumference and then area

Circumference(C) = 2πr

r = C/2π

r = 20/2π

r = 10/π

Area = πr²

Area = π × 10/π × 10/π

Area = 100/π

Area = 100/3.14

Area = 10000/314 = 31.84 cm² (approx)

Area = 32 cm² (Rounding to nearest whole number)

Do you have 1 7/8 divided by one half. With dividing you multiply by the reciprocal of 1/2 which is 2/1. Before you do that change 1 7/8 into a mixed number which is 15/8. 15 x 2= 30, 8 x 1=8. New fraction is 30/8. Now as a mixed number it is 3 6/8 which simplifies to 3 3/4. So your answer is D
