a. Okay. So we have to make a table for the amount of butterflies to total insects. Let's simplify the ratio. 36:100 simplifies to 9:25. We can use that ratio to make this table. Just multiply 25 by the amount it takes to get to 50 or 100, and multiply by the same amount at the top to find the amount of butterflies. If you do it correctly, your table should be as shown below in the image.
b. On that note, let's solve for the amount of butterflies in the conservatory. There are 450 total of them. Let's divide 450 by 100 to find the amount we will multiply by. 450/100 is 4.5. We will mutliply 36 by that amount to find the total amount of butterflies. 36 * 4.5 is 162. That's it. There are 162 butterflies in the conservatory.

Answer:
Part A
1. Perimeter of the outside edges = 24 inches
2. One possibility is: length = 8 in. and width = 8 in.
second possibility is: length = 16 in. and width = 4 in.
3. Area of the wood portion = 11 [tex]inches^{2}[/tex]
4. New dimensions are:
Length = 17.5 ft.
Width = 12.5 ft.
Part B
Area of the picture = 24 [tex]inches^{2}[/tex]
Area of the frame = 35 [tex]inches^{2}[/tex]
Step-by-step explanation:
Part A
1. Perimeter of the outside edges = 2(length + width)
= 2(7 + 5)
= 2(12)
= 24 inches
2. If the area of the frame was 64 [tex]inches^{2}[/tex], then the two possible dimensions are:
8 × 8 and 16 × 4
i.e., one possibility is: length = 8 in. and width = 8 in.
second possibility is: length = 16 in. and width = 4 in.
3. Area of the wood portion = Area of the frame - Area of the picture
= (5 × 7) - (4 × 6)
= 35 - 24
= 11 [tex]inches^{2}[/tex]
4. The scale factor is:
1 in. = 2.5 ft.
So, its length = 7 in. = 7(2.5) = 17.5 ft.
width = 5in. = 5(2.5) = 12.5 ft.
Part B:
Length of the picture = 6in.
Width of the picture = 4 in.
Area of the picture = Length × Width
= 6 × 4
= 24 [tex]inches^{2}[/tex]
Length of the frame = 7in.
Width of the frame = 5 in.
Area of the frame = 7 × 5 = 35 [tex]inches^{2}[/tex]
Part A
1) Perimeter of the outside edges
24 inches
2) One possibility is:
length- 8 inches
and width - 8 inches
3) Area of the wood portion
= 11
4) New dimensions are:
Length - 17.5 feet
Width - 12.5 feet
Part B
Area of the picture
- 24
Area of the frame
- 35
Step-by-step explanation:
first part-
1) Perimeter of the outside edges = 2(length + width)
= 2(7 + 5)
= 2(12)
= 24 in
2) if the area of the frame was 64 then there are two possible dimensions
8 × 8 and 16 × 4
the first possibility
length = 8 inches
width = 8 inches
the second possibility
length = 16 inches
width = 4 inches
3) Area of the wood portion= Area of frame - Area of picture
= (5 × 7) - (4 × 6)
= 35 - 24
= 11
4)The scale factor
1 inches = 2.5 feet
length = 7 inches
= 7(2.5)
= 17.5 feet
width = 5 inches
= 5(2.5)
= 12.5 feet
Second part-
Length of picture
= 6 inches
Width of picture
= 4 inches
Area of the picture
(Length × Width)
= 6 × 4
= 24
Length of frame = 7 inches
Width of frame = 5 inches
Area of frame = 7 × 5 = 35

The correct answer is C.
[tex] |SU| = 8.1units[/tex]
EXPLANATION
The given points are,
[tex]S(2,1) \: \: and \: \: U(6,8).[/tex]
We use the distance formula to determine the distance between the two points.
[tex]d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2} [/tex]
We substitute the points to obtain,
[tex] |SU| = \sqrt{(6- 2) ^{2} + (8 - 1) ^{2} } [/tex]
We simplify to obtain,
[tex] |SU| = \sqrt{(4) ^{2} + (7) ^{2} } [/tex]
We further simplify this to obtain,
[tex] |SU| = \sqrt{16 + 49} [/tex]
[tex] |SU| = \sqrt{65} [/tex]
This evaluates to,
[tex] |SU| = 8.062[/tex]
We round to the nearest tenth to get,
[tex] |SU| = 8.1units[/tex]
A model car has a windshield with dimensions 1/18 the size of a real car windshield. They rectangular windshield of the real car has an area of about 2318 square inches, with a width of 61 inches. What are the side lengths of the model car's windshield? Round to the nearest hundredth. Justify your answer
Answers
The first step here is to figure out the missing length of the real car. We know the area is 2318 square inches, and the width is 61 inches. Since the area of a rectangle is length x width, we can find the length by doing the opposite of multiplication which is division.
2318 ÷ 61 = 38
So the dimensions of the real car windshield is 61 and 38.
Now, we have to find what 1/18 of 61 is, and what 1/18 of 38 is. We can divide 61 and 38 by 18 to find these values.
The attached image shows that division process, and how we can take it a step further to find the area of the model car windshield.

Safety standards require a pool to add 3 chlorine tablets to every 2,000 gallons of water. Today, the lifeguards at Park Pool added 8 chlorine tablets to their pool's 10,000 gallons of water. How does Park Pool's chlorine compare to the safety standards?
Answers
They have less chlorine than the safety standards require.
Answer: With the help of Ratio we can compare Park Pool's chlorine to the safety standards.
Step-by-step explanation:
Since we have given that
Safety standards requires a pool to add 3 chlorine tablets to every 2,000 gallons of water.
Number of chlorine tablets = 3
Volume of water = 2000 gallons
So, Ratio will be
[tex]3:2000\\\\=1:\frac{2000}{3}\\\\=1:666.67[/tex]
Now, According to question, the lifeguards at Park Pool added 8 chlorine tablets to their pool's 10000 gallons of water.
So, Number of chlorine tablets = 8
Volume of water = 10000 gallons
So, Ratio will be
[tex]8:10000\\\\1:1250[/tex]
Hence, with the help of Ratio we can compare Park Pool's chlorine to the safety standards.

Answers
Final answer:
The equivalent ratios to 4:9 are 20:45, 12:27, and 8:18 because they all simplify proportionally to 4:9.
Explanation:
To determine which of the given ratios are equivalent to 4:9, we need to have ratios that can be simplified to 4:9 or for which 4:9 can be scaled up proportionally. We check each given ratio by either simplifying it or finding a common multiplier that would lead us back to 4:9.
9:28 is not equivalent because it does not simplify to 4:9 or scale from 4:9.20:45 simplifies to 4:9 when both numbers are divided by 5.12:27 simplifies to 4:9 when both numbers are divided by 3.4:24 is not equivalent because it simplifies to 1:6, not 4:9.8:18 simplifies to 4:9 when both numbers are divided by 2.Therefore, 20:45, 12:27, and 8:18 are equivalent ratios to 4:9.

A right triangular prism is shown. Find (A) the total surface area and (B) the volume. You must show formulas and your work.
10m height
8m width
10.77m
Answers
We are going to use the rectangular prism of the image as a guide:
First of all, the AC segment is calculated using the Pythagoras' theorem:
[tex]AC= \sqrt{ AB^{2}+ BC^{2} } =\sqrt{ 10^{2}+ 8^{2} }=12,81 m[/tex]
(A) The surface area of a prism is the sum of the surface areas of each face.
For the 2 triangles ABC and DEF
[tex]A=2*(1/2*b*h)=2*(1/2*8m*10m)=80m[/tex]
For the ABEF Rectangle
[tex]A=w*l=10,77m*10m=107,7m^{2}[/tex]
For the ACDE Rectangle
[tex]A=w*l=10,77m*12,81m=137,96 m^{2}[/tex]
For the BCDF Rectangle
[tex]A=w*l=10,77m*8m=86,16 m^{2}[/tex]
To finish you need to sum up the areas of each face:
[tex]SA=2A_{ABC}+ A_{ABEF}+A_{ACDE}+A_{BCDF}= \\ 80 m^{2} +107,7m^{2} +137,96m^{2} +86,16m^{2} =411,82m^{2} [/tex]
(B) The volume of a prism is the product of the area of its base and the height of the prism. In this case, the base is a triangle so the formula and the calculations for the volume are as follows
[tex]V= \frac{1}{2} *w*h*l= \frac{1}{2}* 8m*10m*10,77m=430,8m^{3} [/tex]

A hollow ball is made up of rubber that is 2 centimeters thick. The ball has a radius to the outside surface of 6 centimeters. What is the approximate volume of rubber used to make the ball? Use 3.14 for pi.
a. 33.5cm^3
b. 267.9cm^3
c. 636.4cm^3
d. 994.3cm^3
Answers
The volume of rubber used to make the hollow ball is approximately 636.4 cm^3, which is calculated by subtracting the inner space volume from the total volume of the ball.
To find the volume of rubber used to make a hollow ball, we need to calculate the volume of the entire ball and then subtract the volume of the inner empty space. The ball's external radius is 6 centimeters, and the rubber thickness is 2 centimeters, which makes the inner radius 4 centimeters (6cm - 2cm).
The formula to calculate the volume of a sphere is V = (4/3)
y. Using
for pi and plugging in the numbers, we get:
(6)
= 904.32 cmVolume of the inner space (inner radius of 4cm): V = (4/3) 3.14 (4)
= 268.08 cm
To find the volume of the rubber used, we subtract the smaller volume from the larger volume:
904.32 cm - 268.08 cm = 636.24 cm
Therefore, option c. 636.4cm is the approximate volume of rubber used to make the ball.
