lana [24]

Answer:

804 feet

Step-by-step explanation:

Given: Dimension of a basketball court is 84 feet by 50 feet.

Considering the shape of basketball court is in rectangle shape.

∴ Finding the perimeter of rectangle to know total number of feet in one round.

Perimeter of rectangle= $2(l+w)$

where, l= length

w= width

∴ Perimeter of rectangular court= $2(84\ feet + 50\ feet)$

⇒ Perimeter of rectangular court= $2(134\ feet)$

Opening parenthesis

⇒ Perimeter of rectangular court= $2\times 134\ feet= 268\ feet$

Hence, Brett run 268 feet in one round of warm up.

As given, Brett ran around the court 3 times.

Input in standard form the equation of the given line.

mario62 [17]

Use equation of line which passes through the 2 points $A(x_1,y_1),B(x_2,y_2)$ .

$y-y_1= \frac{y_2-y_1}{x_2-x_1}(x-x_1) \\ \\A(1,5),B(-2,3)
\\ y-5= \frac{3-5}{-2-1}(x-1)
\\y-5= \frac{2}{3} (x-1)
\\y-5=\frac{2}{3}x-\frac{2}{3}
\\3y-15=2x-2
\\-2x+3y=-2+15
\\-2x+3y=13$

You plan on purchasing a car in the next year. The car that you are interested in lists for $23,000 after taxes, license, and do

bixtya [17]

Answer:

c. 8 months.

Step-by-step explanation:

First let's break down all the expenses and taxes to come up with how much we save each month and subtract it to our total salary monthly.

Total Salary : $1312.00 x 2 = $2,624.00

Current Savings : 2/3 or 0.67 = $15333.33

| Expenses |

Monthly Expenses : $1,150.12

Social Security : 6.2% or 0.062 x 2,624 = $162.69

Medicare : 1.45 or 0.0145 x 2,624 = $38.05

Taxes: $53 + $101.35 = 154.35 x 2 = $308.7

So we sum up all the expenses.

= $1659.56 Total Expenses.

Now we have to find how much extra money we have each month.

= $964.44 Extra Money

Now we subtract our current savings to the total price of the car.

= -7666.67 Balance

Now we divide the total balance to our extra money monthly.

= 7.949 Months or 8 Months
