Johnson Canniver has a repair shop. He bought a used lawn mower for $35.00 from a customer. He spent $39.17 on parts to repair t

he mower. He also painted and polished the mower at a cost of $36.43. He was able to sell the refurbished lawn mower for $155.00. What was Johnson's markup on the lawn mower to the nearest cent?

Answer:

$44.40

Step-by-step explanation:

Markup is the difference between the sell price and the cost of building

1) Find total cost of building the lawn mower: $35 + $39.17 + $36.43 = $110.6

2) Subtract the total cost from the sell price: $155.00 - $110.6 = $44.40

Find the perimeter of the triangle to the nearest whole unit.<br> 18.<br> 16.<br> 14.<br> 12.
devlian [24]

Answer:

14

Step-by-step explanation:

Perimeter of the ∆ = sum of the length of the 3 sides.

The length of the 3 sides can be calculated by using the distance formula, d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}, to find the distance between the vertices of the ∆.

The coordinates of the 3 vertices are:

(-1, 3), (2, 2), (-2, -2)

Distance between (-1, 3) and (2, 2):

Let,

(-1, 3) = (x_1, y_1)

(2, 2) = (x_2, y_2)

d = \sqrt{(2 -(-1))^2 + (2 - 3)^2}

d = \sqrt{(3)^2 + (-1)^2}

d = \sqrt{9 + 1} = \sqrt{10} = 3.2 units

Distance between (2, 2) and (-2, -2)

Let,

(2, 2) = (x_1, y_1)

(-2, -2) = (x_2, y_2)

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

d = \sqrt{(-4)^2 + (-4)^2}

d = \sqrt{16 + 16} = \sqrt{32} = 5.7 units

Distance between (-2, -2) and (-1, 3)

Let,

(-2, -2) = (x_1, y_1)

(-1, 3) = (x_2, y_2)

d = \sqrt{(-1 -(-2))^2 + (3 -(-2))^2}

d = \sqrt{(1)^2 + (5)^2}

d = \sqrt{1 + 25} = \sqrt{26} = 5.1 units

Perimeter of triangle = 3.2 + 5.7 + 5.1 = 14.0 units

What is the measure of the exterior angle
Nataliya [291]

Answer:

That exterior angle is equal to 87 degrees.

Step-by-step explanation:

In order to find the measure of the exterior angle, we start by trying to find x. We can do this by adding up the 3 interior angles and setting them equal to 180. The first angle is equal to 43. The second angle is equal to x + 15. The third angle is equal to 180 - 3x (which we know because the angle and 3x is equal to 180). So we set equal to 180.

43 + (x + 15) + (180 - 3x) = 180 ----> Combine like terms.

238 - 2x = 180 -----> Subtract 238

-2x = -58 ----> Divide by -2

x = 29

Now that we have the x value, we can plug into the exterior angle measure to get the value.

3x = 3(29) = 87 degrees
