(-4)⁴ = (-4)*(-4)*(-4)*(-4)
= [(-4)*(-4)] * [(-4)*(-4)]
Because (-4)*(-4) = 16, therefore
(-4)⁴ = 16*16 = 256
Answer: 256
Answer:DON'T KNOW SO DON'T LOOK AT ME
Step-by-step explanation:
Common factors for the various terms include -1, 7, y. Factoring out the product of those gives ...
... -7y(3xz +4x +5z) . . . . . . matches selection B)
15 gallons of 35% peroxide solution contains 0.35 × 15 = 5.25 gallons of hydrogen peroxide. The rest of the volume is made up of 15 - 5.25 = 9.75 gallons of water.
If we add gallons of water to the solution, the amount of hyrdrogen peroxide in the solution stays the same, but the volume of water increases to gallons, and the total volume increases to gallons.
To get a concentration of 8% in this diluted solution, we add gallons of water such that
Solve for .
To get the desired concentration, one must add 50.625 gallons of water, and one will end up with a total volume of 65.625 gallons of solution.
Answer:
The volume inside the cylinder is .
Step-by-step explanation:
Given : Four spheres of radius 6 cm just fit inside a cylinder.
To find : Calculate the volume inside the cylinder that is empty ?
Solution :
The volume of the cylinder is volume of 4 spheres.
The volume of sphere is
The radius is 6 cm.
The volume of four spheres is
Therefore, the volume inside the cylinder is .
