Answer:
x=500
Step-by-step explanation:
7/10=350/x
cross-multiply by multiplying 350 to 10 and multiply 7 to x.
example:
7•x
350•10
7x=3500
divide both sides by 7
-------------
x=500

I think 20×5=100 then 100÷2
We have two questions, but we need to find the volume of the spherical tank first.
So the formula we will use to find the volume is:
(4/3)πr³=V
Let's fill in the information we have and solve. We will be using 3.14 for pi.
(4/3)(3.14)6³
(4/3)(3.14)(216)
4.1867×216
I'll be using the repeating decimal for 4.1867, I rounded to 7, but there is a repeating 6.
904.32
So the volume is 904.32 yards³ (or 904.78 if using the full pi)
We have to multiply the volume by 7.15.
904.32×7.15
6,465.89
It will cost $6,465.89 to fill the tank with the liquid.
<span>The interest of $1,832.00 the principle of $16,000 for 206 days user the ordinary interest methods to determine the rate. I=Prt 1,832=16,000*206/360*r 1,832=9,155.555556*r r=1,832/9,155.555556 r=0.20 = 20% The rate of the interest is -----------> 20%. </span>
Well you can just keep adding 55 =1hr until you get to 400 the same with 45
