Answer:

A - 2 feet

Step-by-step explanation:

We know that the tank is a rectangular prism which means the volume is equal to length*width*depth

since the tank can hold 30 cubic feet of water, we can divide 30 by the given dimensions of the length and width to find the depth

30/5 = 6

6/3 = 2

therefore, the depth of the tank has to be 2 feet (A)

The sum of the squares of 3 consecutive positive integers is 116. What are the numbers?
elixir [45]
Let's say, the first number is "n"

well, the consecutive number of "n" is "n + 1"and the consecutive number of "n+1" is "n + 1" +1 or n + 2

so, the numbers are (n), (n+1) and (n+2), whatever "n" is

now, the sum of their squares is 116

\bf (n)^2+(n+1)^2+(n+2)^2=116

expand the binomials by FOIL or binomial theorem, and then simplify

What would be an equation for this?
horsena [70]

Answer:

This is a system of equations, meaning there are two equations you will need to use. The first equation would be d + n = 35, where d = dimes and n = nickels. The second equation would be 10d + 5n = 250, since each dime is 10 cents and each nickel is 5 cents totaling at 250 cents. To solve for nickels, solve one equation for dimes and substitute the answer into the d in the other equation. If you need any more help with this one I am happy to help.
