Answer:
The length of this rectangle is 8m.
Step-by-step explanation:
The problem states that the perimeter of a rectangle is twice the sum of its length and it’s width. So
The problem also states that the perimeter is 22 meters. So:
.
Also, it states that I is the length and it is 2 meters more then twice it’s width. So
What’s its length?
The width is 3m. The length is in function of the width, so:
The length of this rectangle is 8m.
Circumfrence is to a circle as perimeter is to a polygon. The circumfrence of a circle always equals the diameter (or two times the radius, since the radius is half of the diameter) times pi.
The circumfrence would be 7926.41π miles because of this.
Should you round pi to 3.14, the circumfrence would be 7926.41 * 3.14.
This is equal to <span>24888.9274 miles. (round that if needed)</span>

Answer:
Step-by-step explanation:
(21x-14)+4=95 - Distributed in the 7 into the parenthesis
21x-10=95 - combine like terms
21x=105 - add 10 to both sides
x=5 - divide both sides by 21
The mean is 20.7
<h3>What is Mean?</h3>
Mean is the average of the given numbers and is calculated by dividing the sum of given numbers by the total number of numbers.
Class Frequency{f} Midpoint of frequency{x} fx
1-7 13 4 72
8-10 14 9 126
11-15 18 13 234
16-20 6 18 108
21-35 13 28 364
36-50 19 43 817
Sum 83 1721
So,
Mean = 1721/83 = 20.7
