To solve this problem you must apply the proccedure shown below:
1. When you plot the given points, you obtain a trapezoid, therefore, you must apply the formula for calculate the area of a trapezoid, which is:

Where
is the larger base,
is the smaller base and
is the height.
2. The dimensions are:

3. Substitute values:

The answer is: 
Answer: (y-c)/m
Reasoning:
Subtract c from both sides [ y-c=mx+c-c ]
Divide m from both sides [ (y-c)/m=mx/m ]
Answer: 
Step-by-step explanation:
To find the circumference of a circle, you can use
. You can set this equal to 21 (feet). The equation to solve at this point would be
.
your son is 24 and you are 28
Step-by-step explanation:
you have to do 52-28
The probability of choosing a purple marble from the given parameters is given as; 29%
<h3>How to find the Probability?</h3>
We are given;
Probability of drawing an orange marble = 23% = 0.23
Probability of of drawing a white marble = 48% = 0.48
Thus, probability of drawing a purple marble is;
P(purple marble) = 100% - (23% + 48%)
P(purple marble) = 29%
