Answer:
$578.30
Step-by-step explanation:
537.95(.075)= 40.35
$40.35 + $537.95 = $578.30
So, the sphere went from 1.2 meters to 1.4 meters.
The radius will always be half of the diameter. So it went from .6 to .7.
Let's divide and see what percent .7 is of .6.
.7÷.6=1.166666666(repeating 6).
This means, it increased by about 16.7%, since it was not doubling, just going up.
8 children because
11 3/7 is equal to 83/14
If each child receives 10/14
83/10
= 8.3
There can't be .3 of a child so round it and you get 8!
Hope this helps!
Answer:
a
Step-by-step explanation:
7a^3(6a^2 + a)^2 - 4a^6
All we have to do here is basically add and subtract exponents!
(6a^2 + a)^2 = 36a^4 + a^2
7a^3(36a^4 + a^2) - 4a^6
252a^7 + 7a^5 - 4a^6
Answer is C.
