Answer:

Part A <u>Question #1) </u>Model B <u>Question #2 </u>A) Model A

Part B <u>Question #1</u> B) Model B uses the smallest liner <u>Question #2</u> C) Model C uses the largest liner

Part C <u>Question #1</u> C, <u>Question #2</u> 576.2 ft², A. <u>Question #3</u> Correct

Part D <u>Question #1 </u>72.8 yd² <u>Question #2 </u>109.38 yd²<u>Question #3</u> A. Triangular Prism

Step-by-step explanation:

Part A

<u>Question #1</u>

The pool as a matter of fact is a parallelepiped, a rectangular prism. And a Rectangular Prism has its Volume

Model A: 18ft x 9 3/4 and 4 1/2 The Volume is given by this formula:

Volume=w*l*d

V_{A}=19*9 \frac{3}{4}*4 \frac{1}{2}} =833.62ft^{3} \\ V_{B} =16*10*5=800ft^{3} \\ V_{C} =15*12*4 \frac{1}{2} =810ft^{3}

Model B needs the smallest amount of water. So Model B

<u>Question #2</u>

Model A needs the largest amount of water to be filled. 833.62 ft³

Part B

The pool liner area is equivalent to a rectangular area. The surface of Pool L_{A}= 18*9 \frac{3}{4} =175.5 ft^{2} \\ L_{B}= 16*10 =160ft^{2} \\ L_{C}= 15*12=180ft^{2}

<u>Question #1</u>

Model B uses the smallest liner

<u>Question #2</u>

Model C uses the largest liner

Part C

<u>Question #1</u>

C A square pyramid is made up of Four congruent triangular faces, since the base is a square.

<u>Question #2</u>

This question asks us how many square feet, of a red tin roof. In other words, what's the area of this red pyramid? So

Since the base of this pyramid is not going to be taken into account. Let's calculate it:

4 * Area of the Triangle, each of its base edge is also the base edge of its triangular face. Base=21.5 ft Height=13.4 ft. There are four triangular faces.

Area of the Triangle = 1/2*b*h

4* (21.5*13.4)/2= 576.2 ft²

Part D

<u>Question #1</u>

This huge prism has 2 equilateral triangles and 3 rectangles. The question asks us the area of the roof: 2 rectangles:

2 (6.5*5.6)=72.8 yd²

<u>Question #2 </u>

What is the outside surface area of this house? The outside surface is given by the sum of the areas of 2 equilateral triangles+ roof

Area of an Equilateral Angle:

A=\frac{l^{2}\sqrt{3}}{4}

So (\frac{6.5^{2}\sqrt{3}}{4})*2=36.58

36.58+72.8 (previous question) =109.38 yd²

<u>Question #3 </u>

This A-frame house is in the shape of a:  A. Triangular Prism

Can anyone teach me how to solve this?
Bumek [7]

Answer:

x=11

Step-by-step explanation:

First you need to make those numbers into an equation. So you will have 4x+4=48. First you have to get the 4 on the other side so you do the opposite of the symbol and subtract 4 from 48 to get 44. So now you have 4x=48. Now you do the opposite og multiplication so you divide 44 by 4 and you get 11. Hope this helped :) I would appreciate it if you made this brainiest answer
