Molly is painting a model house and needs to know how much paint she will need. She knows the surface area of the prism is 216 square inches and the surface area of the pyramid is 84 square inches.

1. Which surface is shared by the two solids? What are the dimensions of this surface?

2. There is another surface that Molly does not need to paint, because it won’t show when she displays the model house. Describe that surface, and explain why it doesn't need to be painted.

3. To find the area Molly needs to paint, she should add the surface areas of both solids and subtract:

twice the area of the triangle
twice the area of the square
three times the area of the square
the area of the square

4. Find the area Molly needs to paint. Show your work, and be sure to include units with your answer.

Oh and here's an image to help you out

Answers

Answer:

1. Base of pyramid; 6 in by 6 in

2. Base of prism; Its dimensions are also 6 in by 6 in, located at the bottom of the house and will not be seen, so it does not require painting.

3. twice the area of the square

4. Area = 228 inches squared

Step-by-step explanation:

For question 4, the area Molly needs to paint is found by adding all the surface areas and subtracting the 2 surfaces that will not be painted: base of pyramid and base of prism (outlined in red). According to the picture, these are both squares with 6 by 6 dimensions.

Step 1. Add all surface areas together

Prism: 6 surfaces

Surface area = 216 inches sq

Front = 6 x 6 = 36 Back = 6 x 6 = 36Top = 6 x 6 = 36Bottom (base) = 6 x 6 = 36Side = 6 x 6 = 36Other side = 6 x 6 = 36

Pyramid: 5 surfaces

Surface area = 84 inches sq

Bottom (base) = 6 x 6 = 36Front triangle = (6 x 4)/2 = 12Back = (6 x 4)/2 = 12Side = (6 x 4)/2 = 12 Other side = (6 x 4)/2 = 12

TOTAL surface area: 216 inches + 84 inches = 300 inches sq

Step 2. Subtract surfaces that are NOT being painted

300 - base of pyramid - base of prism

300 - 2(36)

300 - 72

228 inches sq

Answer: The first option

Explanation:

What we know:

1 mile is equal to 5,280 feetThe length of the fence is 1/4 mileThe width of the fence is 1/8 mile

How to solve:

     By finding the perimeter of the fence in feet, we can check that value against the 4 proportion options listed in the problem. Whichever is true will be the correct answer.

Process:

Perimeter - in feet

Where P is perimeter in miles, x is perimeter in feet, w is width in miles, and L is length in miles.

Set up equation                                                     P = 2w + 2L

Substitute                                                               P = 2(1/8) + 2(1/4)

Simplify                                                                   P = 2/8 + 2/4

Common denominator                                          P = 1/4 + 2/4

Simplify                                                                   P = 3/4 mi.

Translate                                                                x = (3/4)*5280

Simplify                                                                   x = 3960 ft.

For the following: Where m represents the mile unit, f represents the foot unit, and x represents the number of feet of fencing.

First option

Set up equation                                            (3/4)m/x = m/5280f        

Equal variables                                         16[(3/4)m/x) = 12[m/5280f]

Simplify                                                             12m/16x = 12m/63360f

Remove miles                                                          16x = 63360f

Isolate x variable                                                    /16     /16

Solution                                                                       x = 3960 ft.

Second Option

Set up equation                                             (3/8)m/x = m/5280f

Equal variables                                         64[(3/8)m/x] = 24[m/5280f]

Simplify                                                              24m/64x = 24m/126720f

Remove miles                                                            64x = 126720f

Isolate x variable                                                      /64     /64

Solution                                                                          x = 1980 ft.

Third Option

Set up equation                                               x/(3/4)f = m/5280f

Equal variables                                      7040[x/(3/4)f] = m/5280f

Simplify                                                   7040x/5280f = m/5280f

Remove feet                                           7040x = m

Translate                                                 7040x = 5280f

Isolate x variable                                   /7040     /7040

Solution                                                           x = (3/4)f

Fourth Option

Set up equation                                             x/(3/8)f = m/5280f

Equal variables                                  14080[x/(3/8)f] = m/5280f

Simplify                                               14080x/5280f = m/5280f

Remove feet                                        14080x = m

Translate                                              14080x = 5280f

Isolate x variable                                /14080     /14080

Solution                                                         x = 3/8f

Answer: The first proportion

Check:

If the perimeter of the fence, in feet, is the first option, then when

x = 3960, the number of miles and feet should be equal. Let's test this.

(3/4)m/x = 1

(3/4)m/3960f = 1

(3/4)(5280f)/3960f = 1

3960f/3960f = 1

1 = 1

Therefore, option 1 is correct.

Mario walked at a rate of mile every minutes.
​What was his walking rate in miles per hour?

Answers

Answer: 4mi/h

Step-by-step explanation:

We have that Mario walks 2/3 of a mile every 10 minutes. Representing this as a fraction:

[tex]\frac{2/3}{10} \frac{mile}{minute}[/tex]

Next, you can use something called "dimensional analysis." A dimenision in this case would be the units. The desired units we want are miles per hour, but we are given miles per minute. You can use a few conversion factors to help get to those desired units. In 60 minutes, there is 1 hour. Let's multiply this conversion factor by our original fraction:

[tex]\frac{2/3}{10} \frac{miles}{minute}*\frac{60}{1} \frac{minute}{hour}[/tex]

As you can see above, the units of minutes will cancel. This will leave the units of miles on top, and hours on the bottom. Our units are now miles per hour after simplifying things:

[tex]\frac{2/3}{10}\frac{60}{1} \frac{miles}{hour}=2/3*6 \frac{miles}{hour}=4\frac{miles}{hour}[/tex]
