Answer: 8° per day.
Step-by-step explanation:
Based on the information above, since we are informed that in three days, the temperature dropped by 24 degrees, the number of degrees per day that the temperature dropped will be go by dividing 24° by 3 days. This will be:
= 24° / 3 days
= 8° per day
7/6 is the answer. If you divide the denominator by 3, you would get it
.44/.8=×/1
×=.55

Easy
when rock is in water, it takes up a certain volume, say x
so
initial+x=final volume

x=15.2ml
the volme of the rock is 15.2ml
