Meghan unfolded a three dimensional solid and formed the two dimensional figure below. Select all the statements that apply to this figure
Answers
Answer:
The statements that apply to this figure are:
3. The surface area is the lateral area plus the area of the two circles.4. This is the net of a cylinder.
5. The lateral area is the circumference of the circle multiplied by the height of the solid.
Explanation:
First, analyze the 2D figure and imagine what it is in 3D: you may bend the left circle 90º, then roll it along the line of the rectangle all the way up and then bend the other circle 90º.
The rectangle will become the lateral walls of a cylinder and each circle a base.
Thus, the net corresponds to a cylinder.
Now, check every statementÑ
1. This is the net of a cone
FALSE. It is a cylinder2. The volume is found by adding up the areas of the circles and the rectangle.
FALSE. By adding up the areas of the circles and the rectangle you get the area of the cylinder.
3. The surface area is the lateral area plus the area of the two circles.
TRUE. The lateral area of the cylinder is equal to the area of the rectangle. The area of the two circles is the area of the bases of the cylinder.
By adding the lateral area and the area of the bases you get the total surface area of the cylinder.
4. This is the net of a cylinder.
TRUE. Explained above
5. The lateral area is the circumference of the circle multiplied by the height of the solid.
TRUE. The circumference of the circle is equal to the length of the rectangle. Thus, by multiplying this by the height of the rectangle, which is the same height of the solid, you get the area of the rectangle and that is the lateral area of the cylinder.
6. The solid has 3 faces, 6 edges and 4 vertices.
FALSE. The only edges of the cylinder are the rims of the bases and a cylinder does not have vertices.
Hence, the true statements that apply in the figure are:
The surface area is the lateral area plus the area of the two circles.This is a net of a cylinder.The lateral area is the circumference of the circle multiplied by the height of the solid.Cylinder:A cylinder is a three-dimensional solid that holds two parallel bases joined by a curved surface, at a fixed distance. These bases are normally circular in shape (like a circle) and the center of the two bases are joined by a line segment, which is called the axis. The perpendicular distance between the bases is the height, [tex]'h'[/tex] and the distance from the axis to the outer surface is the radius [tex]'r'[/tex] of the cylinder.
Here this unfold is of a cylinder as it has [tex]2[/tex] circulars bare and [tex]1[/tex] rectangle side of the surface.
Total surface area is equal to= Surface area of lateral area + 2 circular area.
Lateral area= height[tex]\times[/tex]circumference of the circle.

a rectangle field has an anrea of 40cm^2. if one side of the field is 3m longer than the other side, find the new area of the field where the length of each side is increased by 10%
Answers
The area of the field where the length of each side is increased by 10% is 48.4 [tex]cm^{2}[/tex].
Step-by-step explanation:
The given is,
A rectangle field has an area of 40 [tex]cm^{2}[/tex]
If one side of the field is 3 cm longer than the other side
The length of new area in each side is increased by 10%
Step:1
Let,
[tex]b[/tex] - One side of rectangle
[tex]l[/tex] - Other side of rectangle
From given.
[tex]l[/tex] - [tex]b[/tex] +3
Formula for area of rectangle,
[tex]Area, a = lb[/tex]
40 = ( b+3) × b
40 = [tex]b^{2}[/tex] + 3b
Solving the above the equation,
b = 5 cm
l = 8 cm
Step:2
If the area of rectangle increased by 10%,
l = 8 + ( 8 × [tex]\frac{10}{100}[/tex] )
= 8.8
b = 5 + ( 5 × [tex]\frac{10}{100}[/tex] )
= 5.5
Area of rectangle is,
a = ( 8.8 × 5.5 )
= 48.4 square centimeters
Result:
The area of the field where the length of each side is increased by 10% is 48.4 [tex]cm^{2}[/tex], if a rectangle field has an area of 40 square centimeters and one side of the field is 3 cm longer than the other side.
Avery received $80 in cash for mowing lawns. She did the following with the $80. Put 20% of the $80 into a bank account. Spent 1/4 of the $80. Kept the rest of the $80 in cash. How much of the $80 did Avery keep as cash?
Answers
Answer:
$48
Step-by-step explanation:
To start off, we know that Avery put 20% of the $80 in her bank account. We can figure out how much 20% of 80 is by multiplying 80 by 20% and then subtracting that number from 80. Remember to switch 20% to its decimal form (20% -> .2).
Step 1) 80 x .2 = 16
Step 2) 80 - 16 = 64
Next, we have to figure out how much 1/4 of the remaining $64 would be. We just simply divide 64 by 4 to figure out how much Avery spent.
Step 3) 64 / 4 = 16
Lastly, since we know Avery spent 16 dollars, we can subtract the 16 from 64 to get our final answer.
Step 4) 64 - 16 = 48
Avery kept $44 of the $80 as cash after putting 20% into a bank account and spending 1/4 of it.
Avery received $80 in cash for mowing lawns. Let's calculate how much she kept after her transactions. First, she put 20% of the $80 into her bank account. Calculating 20% of $80 involves multiplying $80 by 0.20, resulting in $16. Next, Avery spent 1/4 of the $80, which equals $20, as $80 divided by 4 gives $20. To find the amount Avery kept as cash, we subtract the amounts she put in her bank and spent from the original $80.
$80 - $16 - $20 = $44
Therefore, Avery kept $44 of the $80 as cash.

Scott paid 19.99 for a 7.98-kg bag of dog food. A few weeks later, he paid 20.38 for an 8.39-kg bag at a different store. What is the unit price for each bag
Answers
Answer:
Store 1: 19.99/7.98 = 2.51
Store 2: 20.38/8.39 = 2.43
Step-by-step explanation:
unit price is per 1 kg...so you will divide
Store 1: 19.99/7.98 = 2.51
Store 2: 20.38/8.39 = 2.43
The unit price of the first bag of dog food is $2.50 per kg, and the unit price of the second bag is $2.43 per kg.
Explanation:
To determine the unit price for each bag of dog food, we need to divide the total cost of the bag by the weight of the bag. The unit price will tell us the cost per kilogram of dog food. Let's calculate the unit price for each bag.
For the first bag:
Cost = $19.99
Weight = 7.98 kg
Unit price = Cost ÷ Weight
Unit price = $19.99 ÷ 7.98 kg
For the second bag:
Cost = $20.38
Weight = 8.39 kg
Unit price = Cost ÷ Weight
Unit price = $20.38 ÷ 8.39 kg
Let's perform the calculations:
First bag's unit price: $19.99 ÷ 7.98 kg = $2.50 per kg (rounded to two decimal places)Second bag's unit price: $20.38 ÷ 8.39 kg = $2.43 per kg (rounded to two decimal places)So the unit prices are $2.50 per kg for the first bag and $2.43 per kg for the second bag.

5. A 200 pound person weighs 33 pounds on the moon.
a. How much did the person's weight decrease?
Answers
Answer:
Step-by-step explanation:
The answer will be 167
Final answer:
The weight of a 200-pound person decreases by 167 pounds on the moon due to the weaker gravitational force. Weight varies with gravity, but mass remains constant.
Explanation:
If a 200-pound person weighs 33 pounds on the moon, the person's weight has decreased by 167 pounds. The weight decrease can be calculated by subtracting the weight on the moon from the original weight on Earth.
Weight decrease = Original weight on Earth - Weight on moon
Weight decrease = 200 pounds - 33 pounds
Weight decrease = 167 pounds
This calculation shows how weight varies with the acceleration due to gravity, which is weaker on the moon. Therefore, the gravitational force acting on a person on the moon is less, resulting in a lower weight, although the person's mass remains constant.
