Answer:
the answer is C
Step-by-step explanation:
We know that area of rectangle its equail A=l*w.
We know that length is 4 times greater than width, so we can say
l=4x and w=x
Knowing that area A=144 we can say
4x*x=144
-
w=6 - its the width
l=6*4=24 - its the length
Answer:
18 inches, assuming that the height is the length of the TV screen.
Step-by-step explanation:
First off, the shape of a TV screen is a rectangle.
To get the area of a rectangle, the equation would be:
H * W = A
where H = height, W = Width, and A = area.
If we pluck in the values given in the question, we get:
H * 32 = 576
To find out H, we have to get rid of the 32.
To do that, we divide both sides by 32.
Therefore, the equation is now:
H = 18.
Thus, the height of the TV screen is 18 inches.
Answer:
As a percent: 115%
As a decimal: 1.15
As a fraction:
Step-by-step explanation:
<u>Percentages</u>
Suppose Michael spends some amount of money on food, and that money is set at 100%. He leaves a 15% tip for the waitress.
Thus, he is really paying 100%+15% = 115% of the original price.
To express a percentage as a decimal, we just divide by 100:
115% = 115/100 = 1.15
The same division should be simplified instead of operated to express the percentage as a fraction:
115% =
Simplifying by 5:
115% =
Summarizing:
As a percent: 115%
As a decimal: 1.15

Answer:
3
Step-by-step explanation:
7.50 + 6.25x=26.25
6.25x=26.25-7.50
6.25x=18.75
x=3
