Find the surface area of the triangular prism (above) using its net (below).
Answers
Formula for (Area of Rectangle)= length x width
Formula for (Area of Triangle)= 1/2 base x height
Now, we have the formulas. Let’s get started!
(Identification) There are 3 rectangles and 2 triangles. 2 rectangles are of the same size and 2 triangles are of the same size.
Triangles~ the base is 6 and the height is 4.
1/2 (6 x 4) = 12
However, there’s two triangles. (of the same size)
12 x 2 = 24
Rectangles 1 and 2~ the length is 5 and the width is 7
5 x 7 = 35
However, there’s two rectangles. (of the same size)
35 x 2 = 70
Rectangle 3~ the length is 6 and the width is 7
6 x 7 = 42
There’s only one of these.
Now we add all the areas of the shapes together!
24 + 70 + 42 = 136
The surface area is 136.

The circumference of a circle is 50.24 meters.
What is the diameter, in meters? Use 3.14 for π and round to the nearest meter, if necessary.
Answers
We know that ,
Circumference is a circle = 2 pi r
=> 2 pi r = 50.24
=> r = 50.24/2 x 3.14
=> r = 78.8 m
But to find diameter , d = 2 x radius => 2 x 78.8 = 157.73 which is approximately 158
Option d is correct
circumference=radius*2*3.14
50.24=r*2*3.14
1. divide 50.24 by 2
2. divide that answer by 3.14
3. this leaves you with the radius. multiply by 2 for the diameter

What is the total cost of the cleaning service?
Enter your answer in the box.
$
Answers
Answer:
180
Step-by-step explanation:
If supplies cost 54$ and thats 30% of the total cost, that means you would divide 54 by 3 and that would be 18. Then you would times 18 by 10 to get your final answer: 180$. The reason you would times 18 by 10 is because 18 is 10% percent of 100% and 10 times 10 is 100.

Answer:6
Step-by-step explanation:
Heron's Formula is: area = sqrt(s(s-a)(s-b)(s-c)) and s is the semiperimeter
Putting the side lengths in would be:
s = (a + b + c)/2
area = sqrt(6(6-5)(6-4)(6-3)) = sqrt(6*1*2*3) = 3*sqrt(2)
So the answer is 3*sqrt(2) which is equal to 6
Answer:
6 units²
Step-by-step explanation:
You want the area of the 3-4-5 right triangle.
AreaThe area formula for a triangle is ...
A = 1/2bh
where b represents the "base" and h represents the "height". The height is always measured to the vertex opposite the base, in direction perpendicular to the base.
Right triangleThe perpendicular legs of a right triangle have the necessary relationship for either one to be considered the "base", and the other to be the "height."
Here, that means we can call the side of length 3 units the "base" and the side of length 4 units the "height", or vice versa.
This means the area is ...
A = 1/2(3 units)(4 units) = 6 units²
__
Additional comment
Heron's formula for the area of a triangle based on all three side lengths can be used for this, but is more work than necessary.

You have recently purchased a new backpack as show in the picture. The main section of the backpack is made of a rectangle gular prism. Use the diagram to find the volume of your new backpack, then explain how u calculated the answer. Use the pictures with the formulas to help also use the sentence starters.
Sentence Starters:
The volume of the large rectangular prism (the bottom part of the backpack) is __inᶾ.
The volume of the pocket, which is also a rectangular prism is _____ inᶾ.
The volume of the half cylinder, which is the top curve of the backpack, is _____ inᶾ.
When you add all three of these together, you get the total volume of _____ inᶾ.
Hint: Find the volume of each shape; there are 3 of them; two rectangular prisms and half of a cylinder, and then add all 3 of them together. For the cylinder, you only need half, so find the volume of the whole cylinder then divide it by 2 for half. )
Answers
Answer:
Main part of backpack V = 840 inᶾ
Front pocket of backpack V = 64 inᶾ
Top curve of the backpack V = 395.8406744 inᶾ
Total V = 1299.840674 inᶾ
Step-by-step explanation:
1.
As we know, the formula for the volume of a rectangular prism is width x height x length (V = whl). We will use this formula to find the volume of the large rectangular prism (bottom part of the backpack) and the volume of the smaller rectangular prism (the pocket). As for the cylinder, we know the formula for the volume of a cylindrical prism is pi x radius squared x height (V = πr^2h). We will use this formula to find the volume of the half cylinder (top curve of the backpack).
2.
For the large rectangular prism (main part of the backpack), we are given:
w = 7in
h = 10in
l = 12in
Now let's incorporate our formula for the volume of a rectangular prism into this situation.
V = whl
V = 7 x 10 x 12
V = 840 inᶾ
3.
Now for the smaller rectangular prism (front pocket of backpack), we are given:
w = 2in
h = 4in
l = 8in
Now let's incorporate our formula for the volume of a rectangular prism into this situation.
V = whl
V = 2 x 4 x 8
V = 64 inᶾ
4.
Now to calculate volume for the half cylinder (top curve of the backpack), we must first imagine that this is a full, circular cylinder. We are given:
r = 6in
h (which will be the same as the width of the backpack in this case scenario) = 7in
Now let's incorporate our formula for the volume of a rectangular prism into this situation.
V* = πr^2h
V* = π x 6^2 x 7
V* = 791.6813487 inᶾ (round this number if you must)
Now that we have the volume of a whole cylinder, we can halve it (divide by two) since we only need half of the cylinder.
V = V*/2
V = 791.6813487/2
V = 395.8406744 inᶾ (round this number if you must)
5.
Finally, we can add our volumes together to acquire the volume of the backpack as a whole!
Large rectangular prism (bottom part of the backpack) + Smaller rectangular prism (the pocket) + Half cylinder (top curve of the backpack) = Total Volume (Whole backpack)
Recall that:
Large rectangular prism (bottom part of the backpack) = 840 inᶾ
Smaller rectangular prism (the pocket) = 64 inᶾ
Half cylinder (top curve of the backpack) = 395.8406744 inᶾ
So:
Total Volume (Whole backpack) = 840 inᶾ + 64 inᶾ + 395.8406744 inᶾ
Total Volume (Whole backpack) = 1299.840674 inᶾ (round this number if you must)

The length of a pencil is 4.5 inches. The length of a crayon is 2.1 inches.
Step-by-step explanation:
Let pencils be p
Let crayons be c
6 pencils and 5 crayons are 37.5 inches. This will be:
6p + 5c = 37.5 ........ equation 1
7 pencils and 6 crayons are 44.1 inches. This will be:
7p + 6c = 44.1 ........ equation 2
Multiply equation 1 by 7
Multiply equation 2 by 6
42p + 35c = 262.5 (3)
42p + 36c = 264.6 (4)
Subtract 4 from 3
c = 2.1
Plug the value of c into equation 1
From equation 1
6p + 5c = 37.5
6p + 5(2.1) = 37.5
6p + 10.5 = 37.5
6p = 37.5- 10.5
6p = 27
p = 27/6
p = 4.5

Answer:
451.61
Step-by-step explanation:
1) Set a linear equaion
[tex] \frac{98}{x} = \frac{21.70}{100} [/tex]
2) Cross multiply
[tex]21.70x = 98 \times 100[/tex]
3) Multiple the right side
[tex]21.70x = 9800[/tex]
4) Divide both side by 21.70
[tex] \frac{21.70x}{21.70} = \frac{9800}{21.70} [/tex]
5) Solve the linear equation
[tex]x = 451.6129032[/tex]
[tex]x≈451.61[/tex]
Then 21.70% of 451.61 is 98
