The answer to this is B. In order to solve this, you need to divide the gallons with the square feet which means that 2,800,000 that you will divide with 500. The answer that you will get is 5600 gallons per square foot. There is a need for people to have filtered water especially at this day...Read More
The correct answer to this question is E, 1.56%. To get this answer, we can divide the given values in the word problem. We will divide the 28 thousand gallons of filter water by the 1.8 million values of backwashing. This will provide us with 0.0155555556. This would be the correct answer,...Read More
The question does not suggest that the shape is irregular and so to calculate the answer in cubic feet, you merely have to multiply the length by the width by the height of the basin. It is easiest to multiply the first two, find the result and then multiply that by the third...Read More
The correct answer to this item is letter D. To get the surface area of a circle, one must use the formula r squared multiply by pi. Since the radius is not given, divide the diameter by 2. So, 55 ft divided by 2 is 27.5 and this will be the radius.
Next, multiply 27.5 by 27.5 and the pro...Read More
