Answer:
30 inches
Step-by-step explanation:
In equilateral triangle all sides are equal. One side of the triangle EB is also the side of a square.
So, all the sides of the square is 6 inches
Perimeter = sum of all sides
= AB + BC + CD + DE + EA
= 6 + 6 + 6 + 6 + 6
= 5*6
= 30 inches
Answer:
Here,
length of the square BCDE(l)= 6 inches
Also,
length of the equilateral triangle ABE(l)=6 inches
Lastly, Perimeter of figure ABCDE= 5*6
=30 inches
or,Perimeter of the figure ABCDE also=
AB+BC+CD+DE+EA
=6+6+6+6+6
=30inches
Step-by-step explanation:
We know,
length DC of the square BCDE(l)=6inches
So,
DC=BC=BE=DE (All sides of a square are equal)
Again,
length BE of the equilateral triangle ABE=6inches
So,
BE=AB=AE (All sides of a equilateral triangle are equal)
Therefore, Perimeter of figure ABCDE=
AB+BC+CD+DE+EA or, 5*6
(perimeter means to sum all the outer sides a given polygon, in this case it's a Pentagon)

What is the volume of this solid?
O A. 63

O D. 39
Answers
Answer:
Find the cube's volume first (because it's the simplest figure) by using the formula;
(Formula for vol. of cube)
V = [tex]s^{3}[/tex]
Where 's' stands for one side of the cube raised to the power of three.
or
V = w · l · h
Where 'w' stands for the width, 'l' stands for the length, and 'h' stands for the height.
Plug in the values you know since they literally give it to you (I'll be using the formula [tex]s^{3}[/tex]);
V = [tex]s^{3}[/tex]
V = 3^3 → (The symbol ' ^ ' means to the power of.)
V = 27, is the volume of the cube.
Now we find the volume of the pyramid using the formula;
(Formula for vol. of pyramid)
V = (l · w · h) · 1/3
Where 'l' means the length, 'w' the width, and 'h' the height whereas the 1/3 is just dividing the product of those three by 3.
Plug in the values you know using both the lengths from the cube and pyramid.
What we know of the dimensions for the cube:Length = 3
Width = 3
Height = 3(we won't use)
What we know of the dimensions for the pyramid:Height = 4
Use these to figure out the volume for the pyramid.
V = (l · w · h) · 1/3
V = (3 · 3 · 4) · 1/3
V = 36 · 1/3
V = 36/3
V = 12, is the volume of the pyramid.
Add your volumes:-
27(cube vol.) + 12(pyramid vol.)
= 39 is the volume for this whole solid, your answer is D.
Lucas owns a car dealership in Brazil that is having a big sale for the next 3 days. Lucas's car dealership will
lose revenue if it rains because potential customers will stay at home. There is a 50% chance of rain each
of the next 3 days independent of the other days. The table below shows Lucas's potential revenue for his dealership's big sale depending on how many days it rains. What is Lucas's car dealerships' expected revenue over the next 3 days?
Answers
Lucas's car dealerships' expected revenue over the next 3 days is $6800
How to determine the expected revenue?The expected revenue is calculated using the following formula of expected value
[tex]E(x) = \sum x * P(x)[/tex]
The data elements on the table are represented as:
Days Revenue
0 3000
1 1800
2 1300
3 800
So, we have:
E(x) = 0 * 3000 + 1 * 1800 + 2 * 1300 + 3 * 800
Evaluate the sum of the products
E(x) = 6800
Hence, Lucas's expected revenue is $6800

If you want this in the slope-intercept form then here it is:
Slope-intercept formula: y=mx+b
Your coordinates: (-3,2) and (1,10)
To find the slope (which is the "m" in the formula) you need to do this formula:
y2 - y1 / x2 - x1 =
(The 2's and 1's should be subscript)
10-2/1-(-3) = 8/4
8/4=2
The slope should be 2
Formula right now: y=2x+b
You need to find the y-intercept:
That should be a point on the y-axis.
(0,n) **N is used for a variable since we don't have a number yet.
In your coordinate plane, (0,4) is your y-intercept.
When writing the y-intercept in the formula don't write a coordinate write the "y"

Cindy puts two different-sized weights on a scale. One size weighs 2 ounces and the other size weighs 5 ounces. All of the weights on the scale
weigh 50 ounces combined.
Create an equation to model a possible number of 2-ounceweights, x, and 5-ounce weights, y, that are on the scale
Answers
Answer: 2x+5y=50
Step-by-step explanation:
x=number of 2-ounce weights
y=number of 5-ounce weights
Because of this you will write the total weight (50) is equal to __. On the other end you will multiply the possible number of 2-ounce weights to 2 because this will give you the weight for the 2 ounce. The same is done for the 5-ounce weights. Once you combine both of them you would get the total weight. Which is why 2x+5y=50 is the answer.

lesson 10.2 area of composite figures worksheet assigment
Answers
The composite figure includes a rectangle and trapezoid
The area of the composite figure is 810.5cm².
How to determine the area?From the complete question, we have the following parameters:
Shapes: Rectangle and trapezoid
The area of the rectangle is:
Area = Length × Width
So, we have:
Area = 15 × 23
Area = 345cm²
The area of the trapezium
Area = 0.5 × (a + b) ×h
So, we have:
Area = 0.5 × (15 + 34) × 19
Area = 0.5 × 49 × 19
Area = 465.5cm²
Add both areas to calculate the area of the composite figure
Total area = 345cm² + 465.5cm²
Total area = 810.5cm²
Hence, the area of the composite figure is 810.5cm².
