What is the perimeter of rectangle efgh? startroot 10 endroot startroot 29 endroot units 2 startroot 10 endroot 2 startroot 29 endroot units 22 units 39 units
The perimeter of the rectangle is the length of the boundary of the perimeter of the rectangle. The perimeter of the rectangle is 2(√29+√10).
What is the perimeter of the rectangle?The perimeter of the rectangle is the length of the boundary of the perimeter of the rectangle.
In order to find the perimeter of the rectangle, we need to find the third side(Hypotenuse) of each triangle, therefore,
In ΔA,
[tex](Hypotenuse)^2 =(Perpendicular)^2+(Base)^2[/tex]
[tex]GF^2 = 3^2+1^2\\GF=\sqrt{10}[/tex]
In ΔB,
[tex](Hypotenuse)^2 =(Perpendicular)^2+(Base)^2[/tex]
[tex]EF^2 = 2^2+5^2\\EF=\sqrt{29}[/tex]
In ΔC,
[tex](Hypotenuse)^2 =(Perpendicular)^2+(Base)^2[/tex]
[tex]GH^2 = 2^2+5^2\\GH=\sqrt{29}[/tex]
In ΔD,
[tex](Hypotenuse)^2 =(Perpendicular)^2+(Base)^2[/tex]
[tex]EH^2 = 3^2+1^2\\EH=\sqrt{10}[/tex]
Now, the perimeter of the rectangle is,
[tex]Perimeter\ EFGH = EF+ GF + GH +EH[/tex]
[tex]=\sqrt{29}+\sqrt{10}+\sqrt{29}+\sqrt{10}\\\\=2\sqrt{29}+2\sqrt{10}\\\\=2(\sqrt{29}+\sqrt{10})[/tex]
hence, the perimeter of the rectangle is 2(√29+√10).

Use the information in the table to answer the question. A 3-column table has 1 row. The first column is labeled Species with entry Goldfish. The second column is labeled Mean with entry 7 inches. The third column is labeled Standard Deviation with entry 1. 2 inches. What percentage of goldfish will have lengths between 4. 6 inches and 9. 4 inches? 34% 68% 95% 99. 7%.
By Using the Empirical formula we found that 95% of goldfish will have lengths between 4. 6 inches and 9. 4 inches.
What percentage of goldfish will have lengths between 4. 6 inches and 9. 4 inches?According to the empirical rule :
(1) 68% of the measures should come within 1 standard deviation of the mean.
(2 95% of the measures should come within 2 standard deviations of the mean.
(3) 99.7% of the measures should come within 3 standard deviations of the mean.
So we can see in this problem
The mean is 7 inches.
The standard deviation is 1.2 inches.
4.6 = 7 - 2(1.2)
9.4 = 7 + 2(1.2)
The measures are within 2 standard deviations of the mean, hence, 95% of goldfish will have lengths between 4. 6 inches and 9. 4 inches.
Thus by using the Empirical Rule we found that 95% of goldfish will have lengths between 4. 6 inches and 9. 4 inches.

PLEASE HELP!!!!!! The length of a rectangle is three times its width. If the perimeter of the rectangle is 56 cm, find its area.
Step-by-step explanation:
l = length
w = width
l = 3w
perimeter p = 2l + 2w = 56
using the identity of the first equation
p = 2(3w) + 2w = 56
6w + 2w = 56
8w = 56
w = 7 cm
l = 3w = 3×7 = 21 cm
so, the area is
l×w = 21×7 = 147 cm²
13. The value of a boat is depreciating at a rate of 7% per year. In 2004, the
boat was worth $192,000. Find the value of the boat in 2013.
Answer: Depreciating at 7% 100 - 7 = 93%
93% = 93/100 = 0.93
0.93 is your factor of depreciation.
There are 9 years between 2004 and 2013
So, you set 9 as power on your factor
0.93^9
Multiply your original value
$192,000 x 0.93^9
= $99,918.93
This is the value of the boat in 2013.

What is an Arithmetic Progression?An arithmetic progression(A.P.) is a series, where the difference between consecutive numbers is constant.
The first term of an A.P. is denoted by a, and the common difference is denoted by d.
The nth term of an A.P. series is found using the formula:
aₙ = a + (n-1)d.
The sum of n terms of an A.P. series is found using the formula:
Sₙ = (n/2)(2a + (n-1)d)
How do we solve the given question?We are said that every tree is equally spaced. So the distance between the trees is in arithmetic progression.
With the first tree being at 0 feet from itself, our a = 0.
The distance from the first tree to the sixth tree is 60 feet, so we can say that the 6th term is 60
6th term = a + 5d
or, 60 = 0 + 5d
or, d = 60/5 = 12 feet.
To find the distance between the first tree and the last tree(12th tree), we will find the 12th term of the series,
12th term = a + (12-1)d = 0 + 11(12) = 132 feet.
∴ The distance in feet between the first and last tree is 132 feet.

The inequalities are option B, C and D which are;
B. 11 > (w - 4)² C. y < 3⁴ D. 5+9 < 5×9
Define the term inequalities?Imbalances are numerical articulations that think about two qualities and express that they are not equivalent.
The inequalities are:
B. 11 > (w - 4)²
C. y < 3⁴
D. (5+9) < (5×9)
Here, option A and E are not inequalities. A is a quadratic expression and E is a rational function.
Inequality B says that 11 is greater than the square of the difference between w and 4.
⇒ √(11) > (w - 4)
⇒ w - 4 < √(11) or w - 4 > -√(11)
⇒ w < 4 + √(11) or w > 4 - √(11)
So the solution for inequality B is: w < 4 + √(11) or w > 4 - √(11)
Inequality C says that y is less than 3 to the fourth power (81).
⇒ y < 81
Inequality D says that the sum of 5 and 9 is less than the product of 5 and 9. This is clearly true:
⇒ (5 + 9) < (5 × 9)
⇒ 14 < 45
So the solution for inequality D is: 14 < 45

Alma makes 5 cups of her favorite shade of purple paint by mixing 3 cups of blue paint, 11/2 cups of red paint, and 1/2 a cup of white paint. Alma has 2 cups of white paint.
Assuming she has enough red paint and blue paint, how much purple paint can Alma make?
Answer:
8 1/2 cups
Step-by-step explanation:
Add the blue and red cups of paint together to get 8 1/2 cups of paint.
Since we can assume she has enough, the answer is eight and a half cups of purple paint.
Alma can make 20 cups of purple paint.
What is the unitary method?The unitary method is a method in which you find the value of a unit and then the value of a required number of units.
Given here: For every 5 cups of purple paint alma needs to add 1/2 cup of white paint .
Thus with 2 cups white paint she could make 4 batches of 5 cups of purple paint.
Therefore, total number of purple paint cups from 2 cups of white paint is

A rectangles length is 8 feet longer than twice its width. The rectangles perimeter is 316 feet. Find the rectangles length and width.
The rectangles length is ______ feet, and its width is_____feet.
Answer:
length= 108 feet,
width= 50 feet
Overview of steps:
Define variablesForm two equations using given informationSolve for one variable through substitution/ eliminationSolve for the other variable through substitutionWorking:
Let the length and the width of the rectangle be L and W feet respectively.
L= 2W +8 -----(1)
Perimeter= 2(length) +2(width)
316= 2L +2W
2L +2W= 316
Divide both sides by 2:
L +W= 158 -----(2)
Substitute (1) into (2):
2W +8 +W= 158
Simplify:
3W +8= 158
3W= 158 -8
3W= 150
Divide both sides by 3:
W= 150 ÷3
W= 50
Substitute W= 50 into (1):
L= 2(50) +8
L= 100 +8
L= 108
Thus, the rectangle's length is 108 feet, and its width is 50 feet.

You bring down the original term closest to c then begin your multiplication. Now depending on what symbol your result is tells you whether the next step is to subtract or add, then you continue this process starting with multiplication all the way up until you reach the end. Now, when the last term is 0, that means you have no remainder. Finally, your quotient is one degree less than your dividend, so that −6 in your quotient can be a [tex]\displaystyle -6x^2,[/tex]the [tex]\displaystyle 6x[/tex]follows right behind it, then you end it off with [tex]\displaystyle 5,[/tex]giving you the quotient of [tex]\displaystyle -6x^2 + 6x + 5.[/tex]
