The area of the poster is B. 535.5 in².
Step-by-step explanation:
Step 1:
The poster consists of a rectangle and three-quarters of a circle.
The rectangle has a length of a and width of 3a. The circle has a radius of a.
We calculate the areas of the individual shapes and sum them up to calculate the entire area of the poster.
Step 2:
The area of a rectangle is the product of its length and its width.
If a = 10 inches, the length is 10 inches and the width is 30 inches.
The area of the rectangle 
The area of the rectangle is 300 in².
Step 3:
The area of a circle
Here we only have three-quarters of a circle, so
The area of the given circle 
Here r = a = 10 inches.
So the area of the circle 
The area of the circle is 235.6125 in².
Step 4:
The total area of the shape = The area of the rectangle + The area of the circle.
The total area of the shape 
So the area of the poster is B. 535.5 in².
Answer:
total would be $9.05
Step-by-step explanation:
$0.55 + $8.50
Answer:
x + y = -1
Step-by-step explanation:
To write the equation of a line, find the slope and use it with a point in the point slope form.
You can find the slope using the slope formula.

Substitute m = -1 and the point (2,-3) into the point slope form.

Convert to standard form by applying the distributive property and rearranging the terms.
y+3 = -1(x-2)
y + 3 = -x + 2
x + y + 3 = 2
x + y = -1
Answer: Hi there! Joshua would make 2.20 an hour.
Step-by-step explanation:
The first step is to divide the amount he made in a day by the hour.
8.8 / 4 = 2.20
2.20 is the amount he makes an hour. If you want to make sure, you can multiply the 2.20 by the amount of hours he worked.
2.2 * 4 = 8.80
Have a lovely day!
Answer:

Step-by-step explanation:
There is only one figure in the attached image and the solution (surface area) is as follows:
The shape can be sub-divided into:
1. Rectangle
Dimension: 40 by 35
2. Rectangle
Dimension: 40 by 28
3. Rectangle
Dimension: 21 by 40
4. 2 triangles
Base: 21 and Height: 28
Calculate area of each and add them up to get the surface area of the figure.
1. Rectangle
Dimension: 40 by 35

2. Rectangle
Dimension: 40 by 28

3. Rectangle
Dimension: 21 by 40

4. 2 triangles
Base: 21 and Height: 28

So, the area is:


Factor out 40
