Answer:
Step-by-step explanation:
Area of circle =πr² and r = s/2
Area of the shaded region = area of square - area of the circle
A = s² + πr²
1) Formula for the percent of error:
[estimated measure - real measure]
Percent of error = ---------------------------------------------------- x 100
real measure
2) Calculations:
[95 - 91]
Percent error = --------------- x 100 = 4.4 %
91
Answer: 4.4%
Answer:

Step-by-step explanation:
The slope-intercept form of an equation of a line:

m - slope
b - y-intercept
The formula of a slope:

Q1.
We have the equation of a line <em>p </em>in the standard form

Convert to the slope-intercept form:
<em>subtract 3x from both sides</em>
<em>divide both sides by (-3)</em>

The slope 
From the table we have the points (4, 3) and (7, 5). Calculate the slope of line <em>q</em>:

Divide the slope of <em>p</em> by the slope of <em>q</em>:

Q2.
Parallel line have the same slope. Therefore, if we have the equation of the line in the slope-intercept form, then we have the slope:

Q3.
Parallel line have the same slope.
Calculate the slope from given points (-11, 5) and (-6, 1):
