The area of the patio is 216 square feet. Write an equation that represents the area of the patio
Hoochie [10]

Answer:

216=2w \times w

Step-by-step explanation:

Assuming that the patio is a rectangle, we have

A= l\times w

Where l is the length and w is the width.

Now let's assume that the length of the patio is double than the width.

l=2w

So, the equation that represents this problem is

216=2w \times w

Your take home pay is $1500 and you have 22% withheld in taxes. What is your gross pay?
wlad13 [49]

We have been given that the take home pay is $1500 and 22% is withheld as taxes.

Let us assume that the gross pay is x dollars. Therefore, take home pay must be 78% of x because 22% of the pay is withheld as taxes, so you get to take home only 78% of the gross pay.

Since we have been given that take home pay is $1500 and it is 78% of the total gross pay. Therefore, we can set up an equation:

78\%\text{ of }x=1500\\\frac{78}{100}x=1500\\0.78x=1500\\x=\frac{1500}{0.78}\\x=\$1923.08

Therefore, gross pay is $1923.08

Natasha_Volkova [10]

Answer:

3/5

Step-by-step explanation:

To have the best chance of pulling a pair with the same color you should try to get a pair of black socks. There is a 3/5 chance of pulling a black sock so this means for every 5 socks you pull you get 3 black socks or 2 navy socks. Either way you will get a pair of socks with the same color. (Double check to make sure I'm correct)
