We know that
volume of a bar of soap=2*4*0.5----> 4 in³
<span>A bar of soap is sold for $3 individually
</span>so
$3/4-----> 0.75 $/in³
<span>A three-pack of the same soap costs $8
so
$8*(3*4)----> 0.67 $/in</span>³
<span>if you buy the three-pack you save-----> [0.75-0.67]=0.08 $/in</span>³
the answer is
$0.08
Answer:
9 minutes
Step-by-step explanation:
45/5 equals 9
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
Remember PEMDAS, you have to simplify the exponent first.
