What is the difference in the height of the two rectangles is 7 feet what is the value of the y

13.2 feet

Step-by-step explanation:

if the difference is 7 feet, you can add or subtract 7 from the known height to get a difference. because a height of -0.8 feet isn't physically possible (subtracting), adding 7 to 6.2 (known height) would give you a height of 13.2 feet.

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.
