-You cant really see what 1 says but it says (The net below can be folded to make the triangular prism? Label the dimensions of the prism.)
And 8 says (Calculate the total area of the net and the surface area of the triangular prism from Problem 7. area net= surface area= ___ cm^2)
Answer:
1. Left side = 3 inches, Bottom side = 4 inches, Right side = 2 inches, Top side = 5 inches
2. A = 6 inches²
3. A = 8 inches²
4. A = 10 inches²
5. A = 12 inches²
6. A = 36 inches²
7. Left side = 5 cm, Bottom side = 12 cm, Right side = 4 cm, Top side = 13 cm
8. A = 180 cm²
Step-by-step explanation:
1. Label the dimensions of the prism:
Left side = 3 inches
Bottom side = 4 inches
Right side = 2 inches
Top side = 5 inches
2. Area of the red rectangle:
Formula:
LH = A (Length x Height = Area)
A = 3 x 2
A = 6 inches²
3. Area of the blue rectangle:
Formula:
LH = A (Length x Height = Area)
A = 4 x 2
A = 8 inches²
4. Area of the green rectangle:
Formula:
LH = A (Length x Height = Area)
A = 5 x 2
A = 10 inches²
5. (They gave the formula of the two triangles, but the question said green rectangle? They must've meant yellow triangles)
Area of the yellow triangles:
Formula:
2 (1/2 Bh) (2 (half of base x height))
A = 2(1/2 3 x 4)
A = 2(1/2 12)
A = 2(6)
A = 12 inches²
6. Total surface area of the triangular prism:
Formula:
LH + LH + LH + 2 (1/2 Bh) = Surface Area of the triangular prism (Area of the red rectangle + Area of the blue rectangle + Area of the green rectangle + Area of the yellow triangles = Total surface area of the triangular prism)
A = 6 inches² + 8 inches² + 10 inches² + 12 inches²
A = 36 inches²
7. Label the dimensions of the prism:
Left side = 5 cm
Bottom side = 12 cm
Right side = 4 cm
Top side = 13 cm
8. Total surface area of the triangular prism:
First, we can find the area of each shape, as we had previously to find the total area of the net and the surface area of the triangular prism.
Area of the red rectangle:
Formula:
LH = A (Length x Height = Area)
A = 5 x 4
A = 20 cm²
Area of the blue rectangle:
Formula:
LH = A (Length x Height = Area)
A = 12 x 4
A = 48 cm²
Area of the green rectangle:
Formula:
LH = A (Length x Height = Area)
A = 13 x 4
A = 52 cm²
Area of the yellow triangles:
Formula:
2 (1/2 Bh) (2 (half of base x height))
A = 2(1/2 5 x 12)
A = 2(1/2 60)
A = 2(30)
A = 60 cm²
Total surface area of the triangular prism:
LH + LH + LH + 2 (1/2 Bh) = Surface Area of the triangular prism (Area of the red rectangle + Area of the blue rectangle + Area of the green rectangle + Area of the yellow triangles = Total surface area of the triangular prism)
A = 20 cm² + 48 cm² + 52 cm² + 60 cm²
A = 180 cm²

Answer:
a) If the volume of the prism on the left is 1029 m³, then the volume of the prism on the right is 1536 m³.
b) If the height of the prism to the left is 14 m, the height of the prism to the right will be 16 m.
c) If the surface area of the prism to the left is 392 m², the surface area of the prism to the right will be 512 m².
Step-by-step explanation:
a) To solve, set up a proportion. Volume is three-dimensional, so we need to cube.
(7/8)³=1029/x
Now we can solve using cross products to get 1536.
If the volume of the prism on the left is 1029 m³, then the volume of the prism on the right is 1536 m³.
b) To solve the second one, we also set up a proportion. Height is one-dimensional, so we will not need exponents here.
7/8=14/x
Solve using cross products to get 16.
If the height of the prism to the left is 14 m, the height of the prism to the right will be 16 m.
c) Now we are solving for area, which is two-dimensional. Therefore, we will need to square.
7/8²=392/x
Solve using cross products to get 512.
If the surface area of the prism to the left is 392 m², the surface area of the prism to the right will be 512 m².

Considering area (A) of garden as 30 square feet:
30 = x(2x+7)
Now we need to expand it:
x(2x+7) = 2x^2 + 7x
2x^2 + 7x = 30
Adding this into an Algebra calculator gives us 5/2 or 2.5
So x = 2.5
To prove this:
2(2.5) + 7 = 12
14 * 2.5 = 30

We need to solve for k
y = x
21 = 7k Divide both sides by 7 to solve for k
3 = k
y = xk
y = 5(3)
y = 15
Answer: y = 15

The Spring Middle School gym used to hold 350 people. Now, they are only able to hold 200 people. By what percent did the seating in the gym change? (round your percent to the tenths place)
Answer:
mekekekekeeiwjkwkwiw99 9hebsbwbe
Answer:
43%
Step-by-step explanation:
Find What is the decrease percentage for 350 to 200?
Step by step workout
step 1 Address the formula, input parameters & values
Formula :
Difference
Initial Value
x 100 = Percent Decrease (%)
Initial Value X = 350 & New Value Y = 200
Decrease = (X - Y)
(350 - 200)
350
x 100 = ?
step 2 Apply the values in the percentage decrease {(X - Y)/X x 100} formula
=(350 - 200)
350
x 100
=150
350
x 100
= 42.8571%
(350 - 200)
350
x 100 = 42.8571%
The percentage reduction can be written as 57.1429% of 350.
42.8571 percent decrease (%↓) or reduction from 350 is 200.
If you round it you get 43%
Hope this helps.

2(x+3)=5(x-1)+6. show all steps please.
Answer: x=5/3
Step-by-step explanation:
For this problem, you want to solve for x. You first distribute, get all like terms to one side, and then sovle for x.
2(x+3)=5(x-1)+6
2x+6=5x-5+6. (combine like terms)
2x+6=5x+1 (move all like terms to one side)
5=3x (divide to solve for x)
x=5/3

Regina travels ½ of a kilometer for every ¼ of a minute she drives. You were told that the trip from Times Square to Pelham Parkway is 72 kilometers. How many minutes would her trip have taken by car?
Answer:
36 minutes.
Step-by-step explanation:
The best way to solve this is to find how much distance is traveled in a minute and then divide the total distance by the distance traveled in a minute. Now let's apply.
1/4 x 4 = 1 minute, so in this problem, 1/2 x 4 = 1 minute.
1/2 x 4 = 2.
72 / 2 = 36.
Her trip would have taken 36 minutes by car.
Answer:
36 minutes.
Step-by-step explanation:
For every mile she takes it's 1/2 of a minute. Then just do 72/2 and get 36 :)
Find the area of the following figure.
Answer:
The area is
A = 201.6 or with units we have A = 201.6 cm^2
Step-by-step explanation:
We find the area of the triangle and the rectangle separately, and then add the areas to get the total area
Area of Rectangle = R = (base)(height)
R = (12)(15)
R = 180
R = 180 cm^2
Area of Triangle = T = 1/2(base)(height)
T = (1/2)(12)(3.6)
T = 21.6
T = 21.6 cm^2
Total Area = A = Area of Rectangle + Area of Triangle
A = R + T = 180 + 21.6
A = 201.6
A = 201.6 cm^2
Answer:
The answer is 648.

Answer:
55
Step-by-step explanation:
180 - 120 = 60
65 + 60 = 125
180 - 125 = 55

x would be 55 because of alternate angles

Find 8% of 75. Show your work or explain how you arrived at your answer.
Please make the explanation simple
Answer:
6
Step-by-step explanation:
Let's make 8% into a fraction:
\(\frac{8}{100}\)
Since, finding a fraction of a number is also the same as multiplying the fraction with the number, we have this equation:
\(\frac{8}{100}\) of 75 =
\(\frac{8}{100}\) x 75.
Equaling to the answer:

The difference beteen 9.2 ounces and 8.1 ounces is 1.1 ounces
and the difference in price is .49
so 1.1 ounces cost .49
