Answer:
Step-by-step explanation:
so multiply x by 6x and multipy 7 by 3 and theres ur answer
The first thing to do in this case is to find the volume of the sphere.
We have then:
V = (4/3) * (pi) * (r ^ 3)
V = (4/3) * (pi) * ((4) ^ 3)
v = 268 in ^ 3
Then, the but of the sphere will be given by:
W = (0.075) * (268)
W = 20
Answer:
the weight of the sphere, to the nearest pound is:
A) 20
Answer:
221.67
Step-by-step explanation:
If you take 27 by 22cents it will get the cost of the instalation of the carpet then you have to add that to the cost of the instalation of the carpet itself and you get the final cost
So there are 6 sixths in a whole so 6 times 11 is 66 sixths in 11
Alright, this is simple. You know what the new number is, 54. You know the original number was decreased by 40%. Your looking for the original number, X. So set up an equation.
x-.4x=54
When X stands by itself, it's perceived to value 1.00
1.00-.4x=54
(1.00-.4 [40%]=.6)
.6x=54
Divide both sides by .6 to eliminate everything else.
.6x/.6=54/.6
You get 90. Your original number was indeed 90.
To check it, we can do 90/40%, or 90/.4=54
~Hope this helps!
