Answer:
B. 5/6
Step-by-step explanation:
5 divided by 6 equals .8333.
If 66 feet is a typo for 6 feet, then the answer is 330 feet long. Multiply 6•7.34= 44.04 round to 44. 2424/7.34= 330.245 round to 330. This is the height of the building.
If there is no typo 66/3= 22•2= 44
2424/3= 808•2= 1,616 feet tall.
D and E. If I remember right that should be the answer.
Consider number 17. You know that
17=9+8.
Then for negative numbers you have the same rule (with respect to sign -):
-17=(-9)+(-8).
Since (-9)+9=9+(-9)=9-9=0, you have that
-17+9=(-9)+(-8)+9=(-9+9)+(-8)=0+(-8)=-8.
Answer: -17=(-9)+(-8).
Given that we have the change in temperature over 7 hours and we are looking for the change over 1 hour, we can divide the total change in temperature by 7. Thus, the change in temperature would be 
.
Additionally, this can be solved by equations:
By using two different methods, we can determine that the change each hour was equal to 42/7 C° per hour.
