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 togetherPrism: 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 = 36Pyramid: 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 = 12TOTAL surface area: 216 inches + 84 inches = 300 inches sq
Step 2. Subtract surfaces that are NOT being painted300 - base of pyramid - base of prism
300 - 2(36)
300 - 72
228 inches sq

What is the value of x in the equation 6(x+7.8) =−12?
Answers
Answer:
x = -9.8
Step-by-step explanation:
6(x+7.8) =−12
Divide each side by 6
6/6(x+7.8) =−12/6
(x+7.8) =−2
Subtract 7.8 from each side
x+7.8-7.8 = -2-7.8
x = -9.8
Answer:
-9.8
Step-by-step explanation:
First we distribute.6x+46.8=-12Subtract 46.8 on both sidesWe are left with 6x=-58.8Divide 6 on both sidesX=-9.8In a year, there are 4 months that have 30 days.

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]

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 mileHow 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 proportionCheck:
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.

The equivalent fractions will be 2:5 ard 12:30.
Step-by-step explanation:
Equivalent fractions simply mean the fractions that are the same or equal.
Based on the information given, the ratios that are equivalent to 4:10 will be:
4/10 = 2/5
12/30 = 2/5
20/8 = 5/2
8/30 = 4/15
Therefore, the equivalent ratios will be 2:5 and 12:30.

Answer:
2 : 5 and 12 : 30
Step-by-step explanation:
you can find if two ratios are equivalent by multiplying or dividing both quantities by the same number.
Hence:
4 : 10 x 3 on both sides = 12 : 30
Also
4 : 10 divided by 2 on both sides = 2 : 5
Making these equivalent
The others don’t qualify since for:
8 : 30
You would have to multiply the 4 in 4 : 10 by 2, and the 10 by 3, so basically it can’t work.
For 20 : 8
You would have to multiply the 4 in 4 : 10 by 5 and yet divide the 10 by 1.25 which definitely doesn’t work because a, the number used to multiply/divide is the same, and b, because both sides have to be multiplied or divided, not just one each.
