Answer:
y = 4
Step-by-step explanation:
The perimeter of a polygon is the distance around the polygon. This can be found by adding up all of the side lengths. In this problem, one is given an expression for the perimeter and an expression for each side length. Using the formula for the perimeter, one can substitute in all of the given expressions and solve for the vairable.
(4y + 5) + (3y + 2) + (4y + 5) + (3y + 2) = 58 + 3y
Simplify,
4y + 5 + 3y + 2 + 4y + 5 + 3y + 2 = 58 + 3y
14y + 14 = 58 + 3y
Inverse operations,
14y + 14 = 58 + 3y
-3y -3y
11y + 14 = 58
-14 -14
11y = 44

$2 350
Answers
Answer:
720
Step-by-step explanation:
24500 (total) subtracted by (10,700 + 5000 + 1600) =7200. 7200 divide by 10 mo=720
If the student will need to save every month in order to pay off the remaining costs in 10 months, the amount she will need to save per month is $690
Amount and interestGiven the following information from the question
The total cost of fee = $23,500
Amount got as help;
An academic scholarship of $8,200.
Other scholarships and grants of $7.400.
Grandparents pay $1,000
Amunt she had = 8200 + 7400 + 1000
Amount she had = $16600
Amount remaining = 23500 - 16600
Amount remaining = $6900

As it is a parallelogram

Three of the sides will require fencing and the fourth wall already exists. If the farmer has 144 feet of fencing what is the largest area the farmer can enclose ?
Answers
Complete question is;
A farmer is building a fence to enclose a rectangular area against an existing wall. Three of the sides will require fencing and the fourth wall already exists. If the farmer has 144 feet of fencing, what is the largest area the farmer can enclose?
Answer:
A_largest = 2592 ft²
Step-by-step explanation:
Let the width which is going to be perpendicular to the already existing fourth wall be denoted by y. Since there will be 2, it means total width = 2y.
Since the farmer has 144 ft of fencing and the total width is 2y,it means that the length of the fence will be expressed as;
Length = 144 - 2y
Area of rectangular fencing is;
A = y(144 - 2y)
A = 144y - 2y²
To find the largest area, we will find the first derivative and the equate to 0 after which we plug the value of y back into the area equation to get it.
dA/dy = 144 - 4y
At dA/dy = 0;
144 - 4y = 0
y = 144/4
y = 36 ft
Thus, largest area is;
A_largest = 144(36) - 2(36)²
A_largest = 2592 ft²
The largest area the farmer can enclose with the fence with him will be 2592 square feet.
Let the length of the field = [tex]x[/tex] feet
And the width of the field = [tex]y[/tex] feet
Therefore, area of the rectangular field = Length × Width
A = [tex]x\times y[/tex] square feet
Since, length of the fence = 144 feet
And the farmer has to enclose three sides of the rectangle as shown in the figure attached.
Therefore, length of the fence = length + 2(width)
= [tex](x+2y)[/tex] feet
Hence, [tex](x+2y)=144[/tex]
[tex]x=144-2y[/tex]
By substituting the value of 'x' in the expression for the area of the rectangular field.
[tex]A=(144-2y)y[/tex]
[tex]A=-2y^2+144y[/tex]
Find the derivative of the expression with respect to [tex]y[/tex],
[tex]A'=-4y+144[/tex]
Now equate it to zero to get the value of y,
[tex]A'=-4y+144=0[/tex]
[tex]y=36[/tex]
Now substitute the value of 'y' in the expression of area to get the maximum area enclosed.
[tex]A=-2(36)^2+144(36)[/tex]
[tex]=-2592+5184[/tex]
[tex]=2592[/tex] square feet
Therefore, maximum area the farmer can enclose with the 144 feet of fencing will be 2592 square feet.

Answer:
4) 91.75

16x=164
x=10.25
7(10.25)+20=
71.75+20=91.75
Answer:
You are correct 91.75 is the answer
Step-by-step explanation:
This is a cyclic quadralterial since all the. vertices of the quadralterials touch the circle circumference. Opposite angles are supplementary in cyclic quadralterials. Angle C and Angle D are opposite angles so
[tex]7x + 20 + 9x - 4 = 180[/tex]
[tex]16x + 16 = 180[/tex]
[tex]16x = 164[/tex]
[tex]x = 10 \frac{4}{16} [/tex]
[tex]x = 10.25[/tex]
Plug 10.25 into 7x+20
[tex]7(10.25) + 20 = 91.75[/tex]

so we need two even intergeters that add to 70 when we multiply the bigger by 2 and add the smaller to that soooo
70= 2*y + x
but we can express x in terms of y b/c it's a consecutive even integer soo
(b/c x+2 = y, then x = y -2)
70= 2*y + (y-2)
70 = 2y + y - 2
72 = 3y
24 = y :) nice the bigger is 24 so the smaller is 22
70 = 2*24 + 22
70 = 48 + 22
70 = 70 nice !
bigger = 24
smaller = 22
:)
Answer:
bigger = 24

3. Mateus recebe a visita do seu avô Pedro a cada 15 dias. João, o tio dele, o visita a cada 100
e, devido a escalas de trabalho, a cada 12 dias Mateus vai à praia com seus pais. Um belo dia Mans
recebeu a visita do seu avô, do seu tio e foi à praia com seus pais (com o avô e o tio que o visitavam nese
dia). Quantos dias depois este acontecimento se repetirà?
Answers
Answer:
Este acontecimento se repetirá 300 dias depois.
Step-by-step explanation:
Quando os eventos se repetirão no mesmo dia?
Cada evento tem uma frequência.
Eles ocorrem simultaneamente a cada x dias, e x é dado pelo MMC(Mínimo Múltiplico Comum) entre as frequência.
Neste problema:
A cada 15 dias o avô visita.
A cada 100 dias o tio visita.
A cada 12 dias vai à praia.
Quantos dias depois este acontecimento se repetirá?
Os três no mesmo dia vão se repetir após x dias, em que x é dado pelo MMC de 15, 100 e 12
MMC de 15, 100 e 12
Fatorando simultâneamente estes valores:
15 - 100 - 12|2
15 - 50 - 6|2
15 - 25 - 3|3
5 - 25 - 1|5
1 - 5 - 1|5
1 - 1 - 1
Então:
mmc(15,100,12) = 2*2*3*5*5 = 300
Este acontecimento se repetirá 300 dias depois.

Samuel says that 25% is greater than 0.3.
Is he correct? Explain your answer.
Answers
Answer: No 0.3 as a percentage is larger than 25%
Step-by-step explanation:
'percent' is 'over hundred'
if you convert 0.3 into a percentage it becomes 30 percent
Samuel says that 25% is greater than 0.3 is not correct statement.
What is Percentage?A percentage is a number or ratio expressed as a fraction of 100.
The percentage is denoted by the symbol %.
The percentage is used or most important application is to compare any two quantities. We compare one quantity against another, with the second quantity rebased to 100 by using percentage.
Samuels says that 25% is greater than 0.3 is a false.
25% when it is converted to decimals.
25 divided by 100
we will get 0.25
and if 0.3 is converted to percentage
0.3×100=30%
We know that 30% is greater than 25%.
hence Samuel says that 25% is greater than 0.3 is not correct.

x = 21°
:::::
arc GK = 9x-22 = 167°
:::::
arc HJ = 5x-7 = 98°

arc HGK = arc GK + 61 + 34 = 262°

arc GKJ = arc GK + 34 = 201‡
Angles in a circle add up to 360 degrees.
[tex]\mathbf{x = 21}[/tex][tex]\mathbf{GK = 167}[/tex][tex]\mathbf{HJ = 98}[/tex][tex]\mathbf{HGJ = 262}[/tex][tex]\mathbf{GKJ = 201}[/tex]The given parameters are:

[tex]\mathbf{HJ = 5x - 7}[/tex]
[tex]\mathbf{JK = 34}[/tex]
[tex]\mathbf{KG = 9x - 22}[/tex]
The sum of angles in a circle is 360 degrees.
So, we have:
[tex]\mathbf{GH + HJ + JK + KG=360}[/tex]
So, we have:
[tex]\mathbf{(9x-22) + 61 + (5x-7) + 34 = 360}[/tex]
[tex]\mathbf{14x = 294}[/tex]
Divide both sides by 14
[tex]\mathbf{x = 21}[/tex]
GK is calculated as:
[tex]\mathbf{GK = 9x - 22}[/tex]
[tex]\mathbf{GK = 9 \times 21 - 22}[/tex]
[tex]\mathbf{GK = 167}[/tex]
HJ is calculated as:
[tex]\mathbf{HJ = 5x - 7}[/tex]
[tex]\mathbf{HJ = 5 \times 21 - 7}[/tex]
[tex]\mathbf{HJ = 98}[/tex]
HGJ is calculated as:
