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.

Miguel wants to buy a condominium. He has the choice of buying it now or renting it with the option to buy at the end of 3 years
kolbaska11 [484]
Total amount paid if he bought = 6000 + 726(12 x 3) = 6000 + 726(36) = 6000 + 26,136 = 32,136
Total amount paid if he rents = 2000 + 37P, where P is the monthly rent

For renting to be cheaper
2000 + 37P < 32,136
37P < 32136 - 2000 = 30136
P < 30136 / 37 = 814.49

Therefore, the maximum rent he could pay is $814

17 one point shots and 39 two point shots were made

Solution:

Given that,

At a basketball​ game, a team made 56 successful shots

They were a combination of​ 1- and​ 2-point shots

Let "x" be the number of 1 point shots

Then, 56 - x is the number of two point shots

The team scored 95 points in all

Therefore,

1(number of 1 point shots) + 2(number of two point shots) = 95

x + 2(56 - x) = 95

x + 112 - 2x = 95

x = 112 - 95

x = 17

Then, number of two point shots = 56 - x = 56 - 17 = 39

Thus 17 one point shots and 39 two point shots were made

Determine the slope from the given graph below:
Greeley [361]

Step-by-step explanation:

the slope is the ratio of "y coordinate difference / x coordinate difference".

so, let's find 2 good points (I mean by that with integer coordinates). I see e.g.

(-1, -1) and (0, -7)

x changes by +1 (from -1 to 0).

y changes by -6 (from -1 to -7).

so, the slope is -6/1 = -6.

D is the right answer.
