Step-by-step explanation:

Gross income= $813.61

Giving the following information:

Sales= $32,874

Fixed salary= $452

Commission= 1.1% paid on sales in excess of $25,000.

To calculate the gross income, we need to use the following formula:

Gross income= 452 + y*x

y= percentage comission

x= sales

For $32,874 sales:

Gross income= 452 + 0.011*32,874

Gross income= $813.61

5x+8y=6p Solve for y

MariettaO [177]

5x + 8y = 6p Subtract 5x from both sides
8y = 6p - 5x Divide both sides by 8
y = $\frac{6}{8}$ p - <span> $\frac{5}{8}$ x</span>

A guy wire for a suspension bridge runs from the ground diagonally to the top of the closest pylon to make a triangle. We can us

forsale [732]

Answer:

740

Step-by-step explanation:

${hyp}^{2} = {opp}^{2} + {adj }^{2}$

Opp=528, 000 feet

Adj = 19,600feet

Hyp=?

${x}^{2} = 528000 + 19600$

${x}^{2} = 547600$

$x = \sqrt{547600}$

Therefore,

$x = 740$

Identify the equation of the circle that has its center at (9, 12) and passes through the origin.

katrin [286]

The circle has center at (9, 12) and passes through the origin.

Equation of the circle in center and radius form is given by

$(x-h)^2+(y-k)^2=r^2$

where r is the radius and center at (h,k)

Now substitute the value of the center we get

$(x-9)^2+(y-12)^2=r^2$

As it passes through the origin so we can write

$(0-9)^2+(0-12)^2=r^2\\ \\ 81+144=r^2\\ \\ 225=r^2\\ \\ r=15\\$

Hence the equation of the circle is

$(x-9)^2+(y-12)^2=15^2$
