What are the answers for Unit 2: Measurement Lesson 13: Measurement Unit Test?
Hey guys I just got done with it anyone still need.
To find the perimeter and area of a polygon, you need to know the length of its sides and the dimensions of its shape. Here are the formulas to use for some common polygons:
For a rectangle:
Perimeter = 2 * (length + width)
Area = length * width
For a square:
Perimeter = 4 * side length
Area = side length squared
For a triangle:
Perimeter = sum of the lengths of the three sides
Area = (base * height) / 2
For a circle:
Circumference = 2 * pi * radius
Area = pi * radius squared
Note that pi is approximately equal to 3.14 and radius is half the diameter of the circle.
To find the area of a composite figure, you need to break it down into smaller, simpler shapes and add their areas together. Here's how to find the area of the composite figure described:
1. First, divide the figure into rectangles and triangles as shown in the following image:
```
________________
| |
| ___ |
| | | |
| |___|1 in |
| 2 in |
|_______________|
|1 in| 3 in |
|____|׀׀׀׀׀׀׀|___|
|_____ 5 in______|
```
2. Then, calculate the area of each rectangle and triangle:
- The top rectangle has length 2 in and width 1 in, so its area is 2 * 1 = 2 square inches.
- The bottom-left rectangle has length 2 in and width 3 in, so its area is 2 * 3 = 6 square inches.
- The bottom-right rectangle has length 5 in and width 3 in, so its area is 5 * 3 = 15 square inches.
- The right triangle has base 1 in and height 2 in, so its area is (1 * 2) / 2 = 1 square inch.
- The left triangle has base 1 in and height 1 in, so its area is (1 * 1) / 2 = 0.5 square inches.
3. Finally, add up the areas of each shape:
2 + 6 + 15 + 1 + 0.5 = 24.5 square inches.
Therefore, the area of the composite figure is 24.5 square inches.
To find the unit price of one Pokemon card, you need to divide the total cost of all the cards by the number of cards. Here's what you need to do:
1. Determine the number of Pokemon cards you have. Let's say you have 5 cards.
2. Determine the total cost of the Pokemon cards. In this case, the cost is $2.96.
3. Divide the total cost by the number of cards:
$2.96 / 5 cards = $0.592 per card
Therefore, the unit price of one Pokemon card is $0.592.
Sure, let's recalculate the unit price of one Pokemon card if you have 4 cards and they cost $2.96.
1. Determine the number of Pokemon cards you have. You have 4 cards.
2. Determine the total cost of the Pokemon cards. In this case, the cost is $2.96.
3. Divide the total cost by the number of cards:
$2.96 / 4 cards = $0.74 per card
Therefore, the unit price of one Pokemon card is $0.74.
To find the ratio of girls to boys in the esports team, you need to divide the number of girls by the number of boys. Then, simplify the fraction (if possible) to get the answer in the form of a ratio. Here's what you need to do:
1. Determine the number of girls and boys in the esports team. You have 9 boys and 5 girls.
2. Divide the number of girls by the number of boys:
5 girls / 9 boys = 5/9
3. Simplify the fraction (if possible):
The fraction 5/9 cannot be simplified any further.
Therefore, the ratio of girls to boys in the esports team is 5:9 or answer (A) 5/14.
