A scuba diver dove from the surface of the ocean to an elevation of −89 9 10 feet at a rate of −20 feet per minute. After spending 12.75 minutes at that elevation, the diver ascended to an elevation of −28 9 10 feet. The total time for the dive so far was 19 1 8 minutes. What was the rate of change in the diver's elevation during the ascent? Round your answer to the nearest hundredth.

the answer is 0.5 mpm

step-by-step explanation:

the line goes half way through the square each time (which is 0.5 or half of course) so that would mean its 0.5 mpm.

can i see the following ?

step-by-step explanation:

step-by-step explanation:

*calories burned = (weight)(calorie factor)*

calories burned = 180 (0.65)

calories burned = 117

the calories he used up is 117, which is 65% of his weight.  

it would be 4 over -2 divided by -1 over 3.

if you want a solution it would be 4

you flip it so it would be 4/-2 divided by 3/-1 then it would be 12/3 and you would simplify it to 4
