Answer:
A =78.5 in^2
Step-by-step explanation:
The area of the circle is given by
A = pi r^2
A = pi * r^2
A = 25 pi
Using 3.14 for pi
A = 25 (3.14)
A =78.5 in^2
6x - 7 = -49
6x = -49 + 7
6x = -42
x = -42/6
x = -7
Answer:
y = -5/4x +27/4
Step-by-step explanation:
"A line passes through the point (8, -1) and has a slope of -5/4
"
I'm guessing you want to formulate an equation.
To do that, we use the Slope-Intercept Form, y = mx + b, where m is the slope, and b is the y- intercept.
Since we know the slope, we can substitute -5/4 for slope.
y = -5/4x + b
To Find B, we will substitute the ordered pair (8,-1) as x and y.
8= -5/4(-1) + b
8 = 5/4 + b
Subtract 5/4 from both sides.
8-5/4 = 5/4-5/4 + b
27/4 = b
Substitute 27/4 as b in the equations.
<u>y = -5/4x + 27/4</u>

Answer:
length = 16m
width = 4m
Step-by-step explanation:
1. if the length is 4 times the size of the width then we can call the width x and the length is 4x
2. make an equation 4x + 4x + x + x = 40m
3. solve the equation 10x = 40 x = 4
4. width = x width = 4m length = 4x length = 16m
5. check this 16 + 16 + 4 + 4 = 40
For this there is no exact square root but the closest it get is about 75.33
