The total length of the fence which John wants to build a fence around his pool and 15 feet from the edge of the pool is 210 ft.
What is the perimeter of a rectangle?The measure of the boundary of the sides of a rectangle is called its perimeter. The perimeter of a rectangle is twice the sum of the sides of the rectangle.
[tex]P=2(a+b)[/tex]
Here, (l) is the length and (w) is the width of the rectangle.
John wants to build a fence around his pool. The pool is 22 feet long by 23 feet wide. The fence is to be 15 feet from the edge of the pool from all the sides.
Thus, add 15 two times in length and width for both side of pool. The length of the fence is,
[tex]l=23+15+15\\l=53[/tex]
The width of the fence is,
[tex]l=22+15+15\\l=52[/tex]
The perimeter of the fence is,
[tex]P=2(l+w)\\P=2(53+52)\\P=2(105)\\P=210\rm\; ft[/tex]
Thus, the total length of the fence which John wants to build a fence around his pool and 15 feet from the edge of the pool is 210 ft.

consumes an average of about 14.000 grams of rice
per year.
Brazil has an approximate population 2.1 x 10^8
people. Each person in Brazil consumes an average of
about 5 x 10^4 grams per year.
How many times as many grams of rice does each
person consume an average in Brazil as in the United
States> Round your answer to the nearest tenth.
Using proportions, it is found that each person consumes 3.57 times as many rice in Brazil and they do in the United States.
What is a proportion?A proportion is a fraction of a total amount.
In this problem, we have that:
The rate in Brazil is of [tex]5 \times 10^4[/tex].The rate in the United States is of [tex]14000 = 1.4 \times 10^4[/tex].Hence, the rate between the consumption in Brazil and in the United States is given by:
[tex]r = \frac{5 \times 10^4}{1.4 \times 10^4} = 3.57[/tex]
Each person consumes 3.57 times as many rice in Brazil and they do in the United States.

Which equation is equivalent to 7(r + 4) - 3?
7*r+7*4*3
7*r*7*4-3
7*r+7*4-3
7*r+7*4
Answer: Choice C
7*r+7*4-3
=========================================================
Reason:
We use the distributive property to go from 7(r+4) to 7*r+7*4
Multiply the outer 7 by each term inside.
Then the -3 tags along without any changes to it
So we go from 7(r+4) - 3 to 7*r+7*4 - 3
This can be simplified further to 7r+25, but your teacher has chosen not to simplify at this time.

Answer:
Your Answer is 11 inches by 2 inches
Step-by-step explanation:
Area of Rectangle: Area = Length * Width
Given information:
Area = 22 in^2Length = 2x - 1Width = x - 4Put that into the Formula.
Area = Length * Width
22 in^2 = (2x - 1) * (x - 4)
Solve.
22 in^2 = (2x - 1) * (x - 4)
[tex]22 = (2x^2 - 9x + 4)\\2x^2 - 9x - 18 = 0[/tex]
Factor it.
(2x^2 - 9x - 18) = 0
(2x + 3)(x-6) = 0
[tex]x=-\frac{3}{2} ,6[/tex]
Plug that into the Length and Width to find the actually Length and Width.
Length:
[tex]2x - 1\\2*-\frac{3}{2}-1\\ -3-1\\-4\\[/tex]
Width:
[tex]x - 4\\-\frac{3}{2}-4\\ -\frac{11}{2}[/tex]
Area = Length * Width
Area = - 4* -11/2

What is box plot?A box and whisker plot, often known as a box plot, shows a data set's five-number summary. The minimum, first quartile, median, third quartile, and maximum make up the five-number summary.
A box is drawn from the first quartile to the third quartile in a box plot. At the median, a vertical line passes through the box.
It is used when showing the distribution of data points across a selected measure and if the box in a box plot is stretched in one direction or the other, then the data is skewed in that direction.
Given data ,
Isabelle kept track of the number of pages in each book she read last summer
Now , let the box plot be represented as A
Now , the first and third quartile along with the median is given below ;
So , the fraction of books which had 200 or fewer books is given by A = 1/2
Hence , the box plot is solved and the fraction is A = 1/2

The value of y is directly proportional to the value of x. If y = 45 when x = 140, what is the value of y when x = 70?
Step-by-step explanation:
Y is directly proportional to X" can be rewritten as a mathematical expression of the form Y = KX
"K" is the constant of proportionality and must be determined from the initial information.
If Y = 45 when X=140 means 45 = 140K
K = 45/140 = 0.32
Now that we know the value of K, we can use it to calculate the value of Y when X=70
Y = (0.32)(70) = 22.4

Use the point-slope equation: [tex]y-y_1=m(x-x_1)[/tex].
Substitute the point (-5, 2) and the slope m = -4 into the equation.

Find the measure of angle
Answer:
112 degrees
Step-by-step explanation:
180-68=112
Since they are supplementary they form a straight angle, or 180 degrees so the angle AED is 112
Answer:
112
Step-by-step explanation:
∠AED and 68 are Linear pair angles.
That is their sum will be equal to 180,
∠AED + 68 = 180
∠AED = 180 - 68
∠AED = 112

Given that;
Graph of the equation:
⇒ y = -|x-2| + 3
To Find: Values of x in below cases:
a) -|x-2|+3>0
b) -|x-2|+3<0
c)-|x-2|+3=0
Solution:
a) -|x-2|+3>0
y=-|x-2|+3
⇒ y > 0
Hence, From the graph y > 0 when x ∈ (-1 , 5)
without using graph :
- |x - 2| + 3 > 0
3 > | x - 2|
| x - 2 | < 3
Case 1 : x - 2 > 0
x - 2 < 3
x < 5
Case2 : x - 2 < 0
x - 2 > - 3
x > - 1
b) -|x-2|+3<0
y=-|x-2|+3
y < 0
From the graph y > 0 when x < - 1 or x > 5
x ∈ R - [-1 , 5]
or, x ∈ (-∞ , - 1) U ( 5 , ∞)
without using graph :
-|x-2|+3<0
3 < | x - 2|
| x - 2 | > 3
case 1 : x - 2 > 0
x - 2 > 3
x > 5
case 2 : x - 2 < 0
x - 2 < - 3
x < - 1
a) -|x-2|+3=0
y=-|x-2|+3
y = 0
From the graph y = 0 when x = -1 and 5
x ∈ {-1 , 5}
without using graph :
-|x-2|+3=0
3 = | x - 2|
| x - 2 | = 3
case 1 : x - 2 = 3
x = 5
case 2 : x - 2 = - 3
x = - 1
Thus, For the equation: y=-|x-2|+3 values of x for below cases are :
a) -|x-2|+3>0 , x ∈ (-1 , 5)
b) -|x-2|+3<0 , x ∈ R - [-1 , 5] or x ∈ (-∞ , - 1) U ( 5 , ∞)
c)-|x-2|+3=0 , x ∈ {-1 , 5}
