All you have to do is multiply both sides by the same number to get an equivalent ratio.
1)volume of the pipeline
The pipeline is a cylinder, therefore;
Volume (cylinder)=πr²h
r=radius
h=height of the cylinder
diameter=6 in*(1 ft / 12 in)=0.5 ft
raius=diameter / 2=0.5 ft / 2=0.25 ft.
height=5280 ft
Volume (pipeline)=π(0.25 ft)²(5280 ft)=330π ft³≈1036.73 ft³.
2) we calculate the number of barrel
1 mile of oil in this pipeline is 330π ft³ of oil.
1 barrel of crude------------------5.61 ft³
x----------------------------------330π ft³
x=(1 barrel*330π ft³) / 5.61 ft³=184.8 barrels
3) we calculate the price.
1 barrel---------------$100
184.8 barrels---------- x
x=(184.8 barrels * $100) / 1 barrel=$18,480
Solution: ≈$18,480
Step 1 (3* (2a+5)) + 5 *(a-2)
Step 2 <span>3 • (2a + 5) + 5 • (a - 2)
</span>Step 3 final result and your anwser
11a+5

Answer:

Step-by-step explanation:
The formula of a surface area of a cube:

The formula of a volume of a cube:

We have

Calculate the edge length (<em>a</em>).
<em>divide both sides by 6</em>

Calculate the volume of a cube:

Answer:
A
Step-by-step explanation:
The constant of proportionality is the ratio between the two proportional variables in a directly proportional relationship. In this case, the variables are
and
.
To find the constant of proportionality, all we have to do is divide any value of
by its corresponding value of
. Let's take the values in the first row of the table. We know that
and
, so the constant of proportionality is
. Hope this helps!
