What number is 70% of 120?please give the equation with x
MA_775_DIABLO [31]
You can set up this equation as:
x = 0.7(120)

Because remember, 70% is equal to 0.7 and x represents the unknown value. So, let's just solve it:
x = 0.7(120)=84

So, 70% of 120 is 84.

3. PLEASE HELP! Jenna just opened a checking account at the bank. Within the first month, she deposited three checks for $34.98,
sashaice [31]

Answer:C) She would have $216.88.

Step-by-step explanation:

A) Deposits:  +34.98; +51.02; +51.22

Withdrawals:  -5.23; -5.22; -7.89

B) -7.89, -5.23, -5.22, +34.98, +51.02, +51.22

The smallest amount will be the largest withdrawal, as it takes away from the account; the largest amount will be the largest deposit, as it adds to the account.

98 + 34.98 = 132.98 + 51.02 = 184.00 + 51.22 = 235.22 - 7.89 = 227.33 - 5.23 = 222.10 - 5.22 = 216.88

A shipping container shaped like a rectangular prism must have a maximum volume of 10 cubic yards. If the container is 2 1/2 yar
denpristay [2]

Answer:

1\frac{1}{7} yards

Step-by-step explanation:

The maximum volume the shipping container can have is 10 cubic yards.

The volume of a rectangular prism is given as:

V = L * W * H

where L is length, W is width and H is height.

To find the maximum height of the container, make H the subject of formula:

H = \frac{V}{L * W}

We have been given the length and width of the container as 2 1/2 yards and 3 1/2 yards respectively.

Hence, the maximum height is:

H = \frac{10}{2\frac{1}{2} * 3\frac{1}{2} } \\\\H = \frac{10}{\frac{5}{2} * \frac{7}{2} }

H = \frac{10}{\frac{35}{4} } \\\\H = \frac{10 * 4}{35} \\\\H = \frac{40}{35} = \frac{8}{7} = 1\frac{1}{7}

The maximum height of the container is 1\frac{1}{7} yards.
