Answer:
y-intercept is zero
Step-by-step explanation:
The general equation of the line passing through the points is
y = mx + b
where m is the slope and b is the y-intercept
We can pick any two points to get the slope of the line;
m = (55.25-8.5)/(13-2) = 46.75/11 = 4.25
So partially , the equation will be;
y = 4.25x + b
To get b , substitute any point and use its x and y values
We have (2,8.5)
8.5 = 4.25(2) + b
b = 8.5-8.5
b = 0
To get the answer you divide the people by the area and it comes out to be 347.980769
Perimeter = (2 × Length) + (2 × Width)
If the length is dependent on the width (because the length is 10 more than the width), we can say that L = W + 10.
To find the answer to the Peri, we have to find out what the W is first.
184 = 2(W + 10) + 2W
184 = 2W + 20 + 2W
184 = 4W + 20
184 - 20 = 4W = 164
164 ÷ 4 = W
41 = W
We have found out width. Our length is W + 10, so L = 41 + 10 = 51
W = 41 and L = 51
Answer:
6
9
6.48
Step-by-step explanation:
this is the easiest way to solve for percentage:
Where all the percents (except 100) would go in part
and the whole number would go in whole
Then multiply 24 × 25 ÷ 100 = 6
Multiply 60 by 25 then divided by 100 = 9
Then for the last one 9 is what percent of 72
all we have to do is multiply 9 and then convert 72 into a decimal (0.72)
Then 9 × 0.72 = 6.48
