The weight of water is 62 1/2 lb per cubic foot. Water that weighs 350 lb will fill how many cubic​ feet?
valentinak56 [21]

The question is worded incorrectly.  It should say the DENSITY of water is 62 1/2 lbs per cubic foot.  Divide the weight by the density to get volume.

(150 lbs) / (62.5 lbs/ft3) = ? ft3 (the two 3's are exponents. so it'd be ft then an exponent of 3.)

Sonja [21]

The expression that is equal to -4 is D 16/-4 which means  option D is correct. ( it should be noted that option D is not written properly)

<h3>Why  is that 4 is equals to  16/-4?</h3>

In a mathematical  expression   when as negative vale is been used to multiply a negative value, then we will have a positive values , same thing with when a negative value is used to multiply a positive value, a negative value will be gotten.

In the case of the question, if positive value is used to divide a negative value, a negative value will be gotten, hence  expression that is equal to -4 is  16/-4 which is means  optionD  is correct.

Therefore, option C is correct.
