Convert the mixed numbers to improper fractions, then find the LCD and combine.
To find the least common denominator first convert all integers and mixed numbers (mixed fractions) into fractions. Then find the lowest common multiple (LCM) of the denominators. This number is same as the least common denominator (LCD).You can then write each term as an equivalent fraction with the same LCD denominator.Hopefully this helps you! ^^

A party hat has a height of 7 inches and a diameter of 6 inches. What is the volume of the party hat in cubic inches? Use 3.14 for pie.
Answers
Answer:
65.94 in³
Step-by-step explanation:
First, we need to determine to the shape, a party hat is a cone.
The volume formula that use to calculate the cone is 1/3hπr².
Notice: h is for height and r is for radius
Using this formula, we can easily set up the equation below:
1/3 · 7 · 3.14 · (6/2)² = 65.94 (cubic inches)
You must halved the diameter first (in this case, 6) and then square it.
So: The answer of this question is 65.94 in³

Answer: The total surface area is 633.9
Step-by-step explanation:
12.25 times 15.75, then divide by 2 = 96.46875 (this is the area of the triangle
Then times 4 = 385.875 (Because there are four triangles
15.75 times 15.75 = 248.0625 (The area of the square)

-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)
Answers
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:
Step-by-step explanation:
First, you would want to subtract the 3 on the left side to the right side to get the 1/5x to be alone.
1/5x>6
Next, we need to solve for x, by multiplying 5 to cancel out the 1/5.
(5)1/5x>6(5)
That leaves us with x>30

Put the following equation of a line into slope-intercept form, simplifying all fractions. 2x-10y=-20
Answers
Slope-intercept form:
y = mx + b
First, you must get y alone by subtracting 2x on both sides of the equation and then dividing both sides by -10:
-10y = -2x - 20
y = -2/-10x - 20/-10
Simplify: y = 1/5x + 2
Answer: y = 1/5x + 2

Find the surface are of this figure
Answers
Answer:
If I am correct, I think the surface area is 448.
Step-by-step explanation:
First start by finding the area of all the sides
Front side. 12 x 10 = 120
2 triangle sides: 8 x 10 = 80, 80 x 2 = 160
Bottom side: 6 x 12 = 72
Back side: 8 x 12 = 96
Then add up the surface area
120 + 160 + 72 + 96 = 448
Btw I don't know if I am correct, but I think this is the way you find surface area.
