Leslye is a salesperson at a home improvement center. She is paid a monthly commission that is 7.5% of her first $1,000 in sales

Inga [223]

Answer:

She sold for $4683.33

Step-by-step explanation:

For a sales of $1000 she is paid 7.5% which is equivalent to $75.

Since she earned $517 , her total sales was more than $1000.

Let she had a sales of $(1000+x).

Then her commission would be $75 + 12% of $x .

But her total commission was $517.

Then commission from sales after she sold for $1000 = $(517 - 75)

= $442

This is also equal to 12% of x.

$0.12 \times x[\tex] = $442x = [tex] \frac{442}{0.12}$

x = $3683.33

Hence she sold for $4683.33

I need Help ! I don't understand this question

astra-53 [7]

Rate of change = difference in y values / corresponding difference in x values

For the first function it is (7-6) / (3 - 0) = 1/3

For the second function its the slope of the line rise / run = 2/6 = 1/3

So they are the same

Option D: The distance between the two points is 13 units

Explanation:

It is given that the two points are $(-5,-2)$ and $(8,-3)$

We need to determine the distance between the two points.

It is also given that the distance between the two points can be determined using the formula,

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Substituting the points $(-5,-2)$ and $(8,-3)$ for the coordinates $(x_1,y_1)$ and $(x_2,y_2)$

Thus, we get,

$d=\sqrt{(8-(-5))^2+(-3-(-2))^2}$

Simplifying, we have,

$d=\sqrt{(8+5)^2+(-3+2)^2}$

Adding the terms, we get,

$d=\sqrt{(13)^2+(-1)^2}$

Squaring the terms, we have,

$d=\sqrt{169+1}$

Adding the terms, we get,

$d=\sqrt{170}$

Simplifying and rounding off the value to the nearest tenth, we have,

$d=13.0 \ units$

Hence, the distance between the two points is 13 units.

Therefore, Option D is the correct answer.

Suppose a home improvement contractor is painting the walls and ceiling of a rectangular room. The volume of the room is 288 cub

ratelena [41]

Answer:

The minimum cost is $17.30c

Step-by-step explanation:

Given

$V = 288$ --- Volume

$C_1 = 0.06$ --- cost of wall paint

$C_2 = 0.16$ ---cost of ceiling paint

Required

Minimum cost of paint

The volume is calculated as:

$V =xyz$

Substitute 288 for V

$288 =xyz$

Make z the subject

$z = \frac{288}{xy}$

The surface area is calculated as:

$Area = 2(yz + xz) + xy$

Because xy represent the dimension of the ceiling and the opposite of the ceiling (the floor) will not be painted. Hence, it does not require a coefficient of 2

The cost is:

$C = 0.06 * 2(yz + xz) + 0.16 * xy$
