120 is the starting value, aka the price of the painting in 2014 before it is increased.
Do cross multiply or butterfly.
For example first one.
18/x=6/10 So cross multiply 18×10 =6x
180=6x
Divide both sides by 6 to get x alone
180÷6=30
So x =30 Do the same to rest

Step-by-step explanation:
yup
First you need to find the volume of the cylinder. Then find the volume of all 4 rubber balls (spheres). Subtract the cylinder's volume by the spheres' volumes.
Volume of cylinder: πr²h
π2.5²(20) = 392.7 cm³
Volume of sphere: 4/3πr³
4/3π2.5³ = 65.45 cm³
392.7 - 65.45 = 327.25
The amount of space in the container unoccupied by the rubber balls is 327 cm³.
Answer:
it should be B,
