Ascuba diver dove from the surface of the ocean to an elevation of
feet at a rate of
-18.6 feet per minute. after spending 14.5 minutes at that elevation, the diver ascended to
an elevation of -28 feet. the total time for the dive so far was 21 minutes. what was
the rate of change in the diver's elevation during the ascent? round your answer to the
nearest hundredth.

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.  

the ratio of balloons to tables is 5: 2 and the constant variation is 5.

the equation is y=5x

c - they will have the same distribution
