Answer:

22.5%

Step-by-step explanation:

Given the dimensions of the screen to be 20by4, the area will be given using formula of area if a square since the screen is square I'm shape.

Area of the screen = length × length

Area of the screen = 20×4 = 80

Similarly, if the dimension of the image is 9by2 its area will be given as;

Area of the image = 9×2

= 18.

The percentage of the total screen occupied by the image can be expressed as;

Area of image/Area of screen × 100%

= 18/80×100%.

= 1800/80

= 22.5%

This means the image covers 22.5% of the total screen.

Find the slope of the line that passes through the points<br> (-5,-6) and (5,10)

muminat

Answer:

8/5

Step-by-step explanation:

To find the slope given two points

m = (y2-y1)/(x2-x1)

= (10- -6)/(5 - -5)

= (10+6)(5+5)

= 16/10

= 8/5

inn [45]

Answer:

$4.30

Step-by-step explanation:

First, find the cost of both games by multiplying the price by 2:

7.85(2)

= 15.7

Then, to find his change, subtract this from 20:

20 - 15.7

= 4.3

So, Luke should get $4.30 back in change.

Find the distance between the two points in simplest radical form.<br> (7,2) and (-1, -3)

Paul [167]

Answer:

The answer is

<h2> $\sqrt{89} \: \: \: \: units \\$ </h2>

Step-by-step explanation:

The distance between two points can be found by using the formula

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

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(7,2) and (-1, -3)

The distance between them is

$d = \sqrt{( {7 + 1})^{2} + ({2 + 3})^{2} } \\ = \sqrt{ {8}^{2} + {5}^{2} } \\ = \sqrt{64 + 25} \\ = \sqrt{89} \: \: \: \: \: \: \: \: \: \:$

We have the final answer as

$\sqrt{89} \: \: \: \: units \\$
