I NEED HELP! The temperature falls from 0 degrees to Negative 12 and one-fourth degrees in 3 and one-half hours. Which expression finds the change in temperature per hour? Negative StartFraction 7 over 2 EndFraction divided by StartFraction 49 over 4 EndFraction
Negative StartFraction 7 over 2 EndFraction times StartFraction 49 over 4 EndFraction
Negative StartFraction 49 over 4 EndFraction times StartFraction 7 over 2 EndFraction
Negative StartFraction 49 over 4 EndFraction divided by StartFraction 7 over 2 EndFraction

Last option is the correct choice.

Step-by-step explanation:

Convert the mixed numbers into fraction and apply the rate formula.

Rate = Change / Unit Time

= 12 1/4 ÷ 3 1/2

= 49/4 ÷ 7/2 (Answer matching with the last option)

= 49/4 x 2/7 (Inverting the second fraction)

= 7/2

= 3 1/2

The rate of change per hour is 3 and a half degrees in temperature.

Best Regards!

the answer is d on edge

step-by-step explanation:

i can not answer the question due to the fact that you spelled "carton" as "cartoon", a cartoon is something you watch on tv, a carton is a box that holds things. and also you've been waiting for this question for a while so why don't you get off your lazy a** and try to figure it out for yourself for once!
