I think that it is saying that 8:15-8:45 is 7.5 miles right? Then 8- 8:15 is 4.5 and you are trying to find the average of an HOUR.
So in order to get an hour you need 15 more mins. Which is 4.5 miles
according to the chart. (8-8:15). So 4.5+4.5+7.5=16.5. Divided by three
is 5.5 miles per hour. I'm not sure but this is what I would do.
1.
area = L x w = 72
L = 2w
72 = 2w*w = 2w^2
divide by 2
36 = w^2
w = sqrt(36) = 6
l = 2*6 =12
perimeter = 2L +2W = 2*12 + 2*6 = 24+12 = 36
2.
sqrt(40)= 6.324555 cm ( round to 6.32 )
6.32 - 4 = 2.32 cm original length of a side
Answer:
True
Step-by-step explanation:
5 + (-8) is the same thing as 5-8
Hope this helps!!!
Answer:
<h2>HJ = 17</h2>
Step-by-step explanation:
The equation:
2 + HI + 12 = 7 + 12
HI + 14 = 19 <em>subtract 14 from both sides</em>
HI = 5
HJ = HI + 12
Substitute the value of HI:
HJ = 5 + 12 = 17
The radius would be 40.82 divided 2 and that is 20.41 and the diameter would be 40.82 times 2 and that is 81.54
