The distance from the basement floor to the roof can be found by taking the difference between their elevations.
37 ft (elevation of the roof) minus (-15 ft) (elevation of the basement floor) is equal to 37 ft + 15 ft = 52 ft.
Therefore, the distance from the basement floor to the roof is 52 feet.
37 ft (elevation of the roof) minus (-15 ft) (elevation of the basement floor) is equal to 37 ft + 15 ft = 52 ft.
Therefore, the distance from the basement floor to the roof is 52 feet.

To find the product of 4/7 and -20/2, we can multiply the numerators and the denominators.
Numerator: 4 * -20 = -80
Denominator: 7 * 2 = 14
So the product is -80/14.
This fraction can be simplified by dividing both the numerator and denominator by their greatest common divisor, which is 2.
Numerator: -80 ÷ 2 = -40
Denominator: 14 ÷ 2 = 7
Thus, the simplified product is -40/7.
Therefore, the answer is A. -2/35 (negative 2 over 35).
