Answer: it's A

Step-by-step explanation:

since the cost for hiring a plumber for three hours costs $120 so in graph A the graph has more likely stopped at $120 on the y axis which can be said as the cost axis too. I'm pretty sure the answer is A!

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.

Answer:

1372 cubic ft.

Step-by-step explanation:

[tex]V=\frac{4}{3} \pi 7^3[/tex]

[tex]V=\frac{4}{3} \pi 343[/tex]

[tex]V=457\frac{1}{3} \pi[/tex]

Since pi is 3 to find the approximate answer, do:
[tex]V=457\frac{1}{3} (3)[/tex]

[tex]V=1372[/tex]

Hence, the volume of the sphere is approximately 1372 cubic ft.

Answer:

V = 1,372 ft³

Step-by-step explanation:

You have been given the equation necessary for calculating the volume of a sphere:

[tex]V = \frac{4}{3} \pi r^{3}[/tex]

In this formula, "V" represents the volume, "π" is the given value (3), and "r" is the radius. While you have not been given the radius, you have been given the diameter (14 ft). The radius is half of the diameter.

radius = diameter / 2

radius = 14 ft / 2

radius = 7 ft

Now, you can plug this value into the formula and simplify to find the volume.

 [tex]V = \frac{4}{3}\pi r^{3}[/tex]                                         <----- Volume formula

[tex]V = \frac{4}{3} * (3) *r^{3}[/tex]                               <----- Plug 3 in for "π"

[tex]V = \frac{4}{3} * (3) * 7^{3}[/tex]                                <----- Plug 7 in for "r"

[tex]V = \frac{4}{3} * (3) * (343)[/tex]                           <----- Solve 7³

[tex]V = 1,372 ft^{3}[/tex]                                   <----- Multiply all the terms together

Answer: y = 1/5x + 2

Check out the workings I have done in the document I have uploaded :)

It is equal. The same either way. :)

Hey there!

PROBLEM #1. 4 * 2,160

4 * 2,160
= 2,160 * 4

= 2,160 + 2,160 + 2,160 + 2,160

= 4,320 + 4,320

= 8,640
Therefore, the answer should be: 8,640

Problem #2. 4 * 2,610
4 * 2,610
= 2,610 * 4

= 2,610 + 2,610 + 2,610 + 2,610

= 5,220 + 5,220

= 10,440

Therefore, the answer should be:

10,440

Good luck on your assignment & enjoy your day!

Answer:

7/10 or 70%

Step-by-step explanation:

There has to be at least two T in each result of the simulation. This means you can also have 3 T's and 4 T's in the result.

These are the results that qualify as having at least two T's.

1. TTTT, 2. TTTT, 3. THTH, 4. HTTT, 5. TTTT, 7. HTHT, 9. THTH

That is 7 out of the 10 results which is 7/10 or 70%

Answer:

76 ft^3

Step-by-step explanation:

What is the volume of this figure?

these are two cuboids side by side, Volume = L * W * h, we find the volume of both and then we add.

4 * 2 * 8 = 64 ft ^ 3

2 * 2 * 3 = 12 ft ^ 3

64 + 12 =

76 ft ^ 3 (your answer)

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:

101

Step-by-step explanation:

3^4 = 3 * 3 * 3 * 3 = 81

4 ⋅ 5 = 4 * 5 = 20

3^4 + 4 ⋅ 5

= 81 + 20

= 101

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:

1092

Step-by-step explanation:

(12x34) x 2 + (12x3) x2 + (34x3) x2 = 408 x 2 + 36 x 2 + 102 x 2

=816 + 72 + 204

= 1092

(the numbers in brackets are the "net" areas)

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)

The sum is 633.9375

Rounded = 633.9

2. 572.56

3. 283.53

4.254.47

5. 63.62

6. 380.13

Step-by-step explanation:

do πr²

r = radius

if you have a diameter like question 4 divide by 2 and you get radius

Answer:

1. A = 660.52 square units. C = 91.11 units.

2. A = 572.56 square units. C = 84.82 units.

3. A = 283.53 square units. C = 59.69 units.

4. A = 254.47 square units. C = 56.55 units.

5. A = 63.62 square units. C = 28.27 units.

6. A = 380.13 square units. C = 69.12 units.

Step-by-step explanation:

The equations for Area and Circumference of a circle are as follows:

You are given the radius (or diameter) of each circle which can be substituted into the above equations for r. Diameter is the entire length across the circle through the center, which is equal to 2(r).

1. A = π(14.5)² = 660.5198. The area is approx. 660.52 square units.

C = 2π(14.5) = 91.106. The circumference is approx. 91.11 units.

2. A = π(13.5)² = 572.555. The area is approx. 572.56 square units.

C = 2π(13.5) = 84.823. The circumference is approx. 84.82 units.

3. A = π(9.5)² = 283.528. The area is approx. 283.53 square units.

C = 2π(9.5) = 59.690. The circumference is approx. 59.69 units.

4. Diameter = 18; 18/2 = 9 = r. So, A = π(9)² = 254.469. The area is approx. 254.47 square units.

C = 2π(9) = 56.548. The circumference is approx. 56.55 units.

5. r = 9/2 = 4.5. So, A = π(4.5)² = 63.617. The area is approx. 63.62 square units.

C = 2π(4.5) = 28.274. The circumference is approx. 28.27 units.

6. A = π(11)² = 380.132. The area is approx. 380.13 square units.

C = 2π(11) = 69.115. The circumference is approx. 69.12 units.

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

Answer:

V = 4000 cm^3

Step-by-step explanation:

The volume of the sphere is given by

V = 4/3 pi r^3

We are given the radius of 10 and are to use 3 for pi

V = 4/3 (3) * (10)^3

V = 4/3 *3 * 1000

V = 4000 cm^3
