Answer:

A =62x^2

Step-by-step explanation:

The formula for surface area of a rectangular prism is given by

A=2(wl+hl+hw)

Given a width of 2x and length of 3x and a height of 5x, substitute into the equation

A = 2(2x*3x+ 5x*3x+ 2x*5x)

A = 2(6x^2 + 15x^2 +10x^2)

Combine like terms

A = 2(31x^2)

A =62x^2

Last month, you were able to purchase 8 computers. By the middle of the current month, you were able to purchase 8 more computer

Arada [10]

Answer:

125 %

Step-by-step explanation:

Computers purchased in the last month = 8

By the middle of the current month, 8 more computers than the last month were purchased. This means, total number of computers purchased by middle of current month = 8 + 8 = 16

Number of computers purchased by end of current month = 2

So,

Total computers purchased by current month = 16 + 2 = 18

We have to find the percentage increase in the number of computers from last month's purchases to the end of this month's purchases. The formula for percentage change is:

$\text{Percentage Change}=\frac{\text{New Value - Original Value}}{\text{Original Value}} \times 100\%$

Here, Original Value is the number of computers from last month and New Value is the number of computers from current month. Using the values in the formula, we get:

$\text{Percentage Change}=\frac{18-8}{8} \times 100\% = 125\%$

Thus, there was a 125% increase from last month's purchases to the end of this month's purchases

Damon can flip 5 pancakes in 20 seconds,

katen-ka-za [31]

Answer:

24 + 30 = 54 pancakes flipped in 2 minutes :)

Step-by-step explanation:

damon = 5 pancakes in 20 seconds

we do 20 x 3 and 5 x 3 to find how many pancakes he can flip in a minute

15 pancakes and a minute, we then multiply them by 2 to get the amount for 2 minutes

30 pancakes flipped in 2 minutes

Hailey = 2 pancakes in 10 seconds. to make it an equal amount of pancakes per second with damon, i will multiply them by 2 to have 4 pancakes in 20 seconds

we will then do 4 x 3 and 20 x 3 to find out how many pancakes per minute

then we multiply by 2 for 2 minutes
