A skateboard was originally priced at $53.00. It is on sale for 15% off. What is the sale price of the skateboard?

Answers

15 po Kasi Di ko alam

Answer:

$45.05

Step-by-step explanation:

To find 10% divide the original number by 10. This is $5.30

To find 5% divide 10% by 2. This is $2.65

Add the two together to get 15%. This is $7.95

Take away the value of 15% from the original number.

$53.00 - $7.95 = $45.05

Answers

The countertop is  8.37 square metersStep-by-step explanation:LetL > the length of the countertopW > the width of the countertopwe know

Answer:

19.83 square meters

Step-by-step explanation:

So, if we are finding the area of a rectangular countertop, we need to multiply the length by the width.          A=lw    l=length    w=width

First, we multiply the length and width of the countertop (13 and 5).

13x5=65 square feet              65 is the area of thecountertop in feet.

Next, we have to multiply that by 0.305 to convert it into meters.

65*0.305=19.825 square meters       If we round it, its 19.83 square meters.

The equation using supplementary angles is x + 100° + 3x = 180°. Then the value of 'x' is 20°.

What is an angle?

The inclination is the separation seen between planes or vectors that meet. Degrees are another way to indicate the slope. For a full rotation, the angle is 360°.

The two angles are said to be supplementary angles if their sum is 180 degrees.

By the above property of angle, the equation is written as,

x + 100° + 3x = 180°

Simplify the equation, then we have

x + 100° + 3x = 180°

4x = 80°

x = 80° / 4

x = 20°

The equation using supplementary angles is x + 100° + 3x = 180°. Then the value of 'x' is 20°.

Answer:

Option (d) is correct.

Slope of given line y = 5x -4 is 5

Step-by-step explanation:

Given equation of line as y = 5x - 4

We have to find the slope of given line.

For the general equation of line y = mx + c , where m is the slope of line and c is the y- intercept.

Slope of line is given by derivative the equation of line with respect to x, that is

Consider the given equation y = 5x - 4

then slope is

Thus, slope of liven line is 5 .

Also, by comparing the given equation with general equation the slope of line is 5 .

Thus, option (d) is correct.
