The figure below is a regular octagon with a side length of 8 inches.
8 inches
To the nearest square inch, what is the area of the figure?
309
118
64
49
Answers
Answer:
309in²
Step-by-step explanation:
Area of an octagon is expressed as;
A=2(1+√2)a²
a is the side length of the octagon
Given
a = 8
Substitute into the formula
A = 2(1+√2)(8)²
A = 2(1+√2)(64)
Expand
A = 2(64+64√2)
A = 128+128√2
A = 128+128(1.414)
A = 128+181.01
A = 309in²
Hence the area of the octagon is 309in²

A recipe for 24 cookies calls for 4 tablespoons of sugar. If you make 40 cookies and use 5 tablespoons, will the cookies taste the same? Explain
Answers
Answer:
Step-by-step explanation:
No, because they wouldn't contain the same amount of sugar per cookie
for the first recipe - 24 cookies with 6 tablespoons
thats 6/24 so 0.25 tablespoons of sugar per cookie
for the second recipe - 36 cookies with 10 tablespoons
thats 10/36 so 0.276 tablespoons per cookie
the cookies in the second recipe would be slightly sweeter than the cookies in the first
The 24cookies per 4 sugar tbsps calls for 1 tbsp for every 6 cookies. This makes the ratio 6:1.
If u divide 40/5, you will get a ratio of 8:1. This means 1 tbsp of sugar in every 8 cookies. Making the cookies less sugary

Find the independent variable and dependent and write an equation (gr 9 hw) 1) To fix a car, Fix-it Auto charges a base fee of $20 plus $40 per hour. 2) The cost of a banquet at Jean's Banquet Hall is $450 for the rental of the hall and $15 per guest. 3) An author earns a royalty of $1.25 for each book sold. 4) Marie has $500 in her bank account. Each week she plans to deposit $20.
Answers
Answer:
Step-by-step explanation:
Using the regression equation :
y = mx + c
y = dependent variable ; x = independent variable ; m = slope ; c = intercept
1.) base fee = $20 ; hourly charge = $40
Hourly charge = independent
Total charge = dependent
Total charge = 40x + 20
x = Number of hours
2.) rental fee = $450; charge per guest = $15
Total rental fee = dependent
Independent = $15 = charge per guest
Number of guest = x
Total fee = 15x + 450
3.)
Royalty earned = dependent variable
Cost per book = $1.25 = independent
Royalty earned = $1.25 * number of books
4.)
Amount deposited per week = $20 = independent variable
Amount in account = dependent variable
y = 500 + 20x
x = number of weeks

Answers
Answer:
x = 11 / x = - 4
Step-by-step explanation:
x² - 7x - 34 = 10
x² - 7x - 34 - 10 = 10 - 10
x² - 7x - 44 = 0
x² + 4x - 11x - 44 = 0
x (x + 4) - 11 ( x + 4) = 0
(x - 11)(x + 4) = 0
(x - 11) = 0 / (x + 4) = 0
x = 11 / x = - 4

Answer:
1.38
Step-by-step explanation:
1.7-0.4=1.8
1.8/1.3=1.38
On graph place point at (1,8) and draw a triangle
The speed of the ball is 2 m/s.
What is Speed?
The speed of the object is calculated as,
Speed = Distance / Time
Given that;
A ball is thrown from a point 6 meters above the ground.
The graph shows the height of the bake above the ground in meters.
Now,
Draw the line perpendicular to both the x - axis and y - axis for 0 to 1 second.
So, we get;
Value of y - coordinate = 2 m
Value of x - coordinate = 1 m
Thus, Speed of the ball = Distance / Time
= 2 / 1
= 2 m/s
So, The speed of the ball is 2 m/s.

The area of a rectangle is 84 inches. It has a length of x−2 and a width of x+3. What are the dimensions of the rectangle?
Answers
(x +2)x = 15
x2 + 2x = 15
x2 + 2x - 15 = 0
Factor the quadratic equation:
(x - 3)(x + 5) = 0
x = 3 or x = -5
Since length can't be negative, discard the answer -5.
If x = 3, then the width is 3 and the length is x + 2 or 5. 5 x 3 = 15 which equals the area.

8 inches by 13 inches

Answer:
[tex]y +6 = -(x +2)[/tex]
Step-by-step explanation:
Given
Perpendicular to: y = x - 7
Passes through (-2,-6)
Required
Find the equation
An equation has the form:
[tex]y = mx + b[/tex]
Where
[tex]m = slope[/tex]
In [tex]y = x - 7[/tex]
[tex]m = 1[/tex]
Since the required equation is perpendicular to [tex]y = x - 7[/tex], then the relationship between their slopes is:
[tex]m_2 = -\frac{1}{m}[/tex]
Substitute 1 for m
[tex]m_2 = -\frac{1}{1}[/tex]
[tex]m_2 = -1[/tex]
The equation is then calculated using:
[tex]y -y_1 = m(x - x_1)[/tex]
Where
[tex]m_2 = -1[/tex]
[tex](x_1,y_1) = (-2,-6)[/tex]
So, we have:
[tex]y - (-6) = -1(x - (-2))[/tex]
[tex]y +6 = -1(x +2)[/tex]
[tex]y +6 = -(x +2)[/tex]
