The exact perimeter of pentagon JKLMN could not be calculated without the lengths of its sides. One would add the lengths of all sides for a polygon, while for a rectangle, such as a town square, the perimeter formula is twice the sum of its length and width.
Explanation:To calculate the perimeter of a pentagon, you need to add the lengths of all its sides. Unfortunately, the specific lengths of the sides of pentagon JKLMN were not provided, so I cannot calculate the exact perimeter. However, I can explain how you would find the perimeter if the side lengths were known. If you have the coordinates of the vertices, you can use the distance formula to find the lengths of the sides between each pair of vertices. Then you would add those lengths together to find the total perimeter. On the other hand, if the pentagon is regular (all sides and angles are equal), you would just multiply the length of one side by 5.
You also provided an example of calculating the perimeter of a rectangle which has a formula of perimeter = 2(length + width). If we use this formula with the given dimensions of the town square, the perimeter would be 2(39.2 meters + 17.5 meters) = 2(56.7 meters) = 113.4 meters.
To find the approximate perimeter of pentagon JKLMN, we add up the given lengths of its sides. Using the information provided, we can estimate that the approximate perimeter of the pentagon is 840,000 km.
Explanation:The perimeter of a polygon is the sum of the lengths of its sides. To find the approximate perimeter of pentagon JKLMN, we need to know the lengths of all its sides.
Since we are not given the lengths of the sides directly, it is not possible to compute the exact perimeter. However, we can use the information provided to find the approximate perimeter.
Using the given information, we know that the perimeter of the pentagon is approximately equal to 200,000 km + 100,000 km + 300,000 km + 240,000 km. Evaluating this expression gives us an approximate perimeter of 840,000 km.

Becky has one piece of paper. She cuts the paper in half and then has two pieces. She cuts these in half to get four pieces. The process continues. Which describes how many pieces she has at each step? (a) p(1) = 1; p(n) = 2p(n-1), for n is greater than or equal to 2 (b) p(1) = 1; p(n) = 1/2p(n-1), for n is greater than or equal to 2 (c) p(1) = 1; p(n) = p (n-1) +1, for n is greater than or equal to 2
1 piece cuts into 2, 2 pieces cuts into 4, 4 pieces get cut into 8, so there is a multiple of 2 involved so the equation needs a multiple of 2 in it.
The correct answer is a) p(1) = 1; p(n) = 2p(n-1), for n is greater than or equal to 2

What does CPCTC mean in Geometry AND when it is used?
Answer:
Corresponding parts of congruent triangles are congruent.
Step-by-step explanation:
With SSS, SAS, ASA, and AAS, you know how to use three congruent parts of two triangles to show that the triangles are congruent. Once you know that two triangles are congruent, you can make conclusions about their other corresponding parts because, by definition, corresponding parts of congruent triangles are congruent.
CPCTC is an acronym for corresponding parts of congruent triangles are congruent.
The usage
CPCTC is often used to determine the similarities and congruence of two or more triangles.
Take for instance, the SSS congruence theorem means that the triangles are similar or congruent by Side-Side-Side.
Using CPCTC, it helps to know when the corresponding sides and/or the corresponding angles of the triangles that are being com pared are congruent.

How many ants does it take to have the same mass as an elephant
Final answer:
To equal the mass of an elephant weighing 8 metric tons, it takes approximately 2 billion ants, each weighing 4×10^-3 grams.
Explanation:
The question asks how many ants would equal the mass of an elephant when the mass of an ant is approximately 4×10^-3 grams and the mass of an elephant is about 8 metric tons. First, we need to convert the mass of the ant into the same units as the elephant's mass. Since there are 1,000 grams in a kilogram and 1,000 kilograms in a metric ton, we can calculate the mass of the ant in metric tons as 4×10^-3 grams × (1 kilogram / 1,000 grams) × (1 metric ton / 1,000 kilograms), which simplifies to 4×10^-9 metric tons. To find the number of ants needed to equal the mass of an elephant, we divide the elephant's mass by the mass of one ant: 8 metric tons / 4×10^-9 metric tons per ant = 2×10^9 ants. Therefore, it takes approximately 2 billion ants to have the same mass as an 8 metric ton elephant.
If a 40-m rope is cut into two pieces in the ratio 3:5 how long is each piece
Final answer:
The 40-m rope cut in a 3:5 ratio gives a 15 m piece and a 25 m piece. Doubling the rope length to 80 m with the same ratio yields a 30 m piece and a 50 m piece.
Explanation:
To find the length of each piece of a 40-m rope cut in the ratio 3:5, we need to work out the parts of the rope that each ratio value represents. First, we add the parts of the ratio together: 3 + 5 = 8 parts in total. Then, we find the length of each part by dividing the total length of the rope by the total number of parts: 40 m ÷ 8 = 5 m per part. Furthermore, to find the length of the smaller piece, we multiply the size of one part by 3, and for the longer piece, we multiply by 5.
Length of smaller piece = 3 parts × 5 m/part = 15 mLength of larger piece = 5 parts × 5 m/part = 25 mYou use a gift card to buy a pair of shorts for $8. There is $32 left on the gift card after your purchase. What was the original amount of your gift card?

Find p+q, given that (q+4)(p+3)-(q+2)(p+1)=44.
We find that p+q = 17.
To find p+q, we need to solve the given equation step by step:
(q+4)(p+3) - (q+2)(p+1) = 44
Expanding both products, we get:
qp + 3q + 4p + 12 - qp - q - 2p - 2 = 44
We notice here that the 'qp' terms cancel each other out. Simplifying, we are left with:
2q + 2p + 10 = 44
Subtracting 10 from both sides gives:
2q + 2p = 34
Divide by 2:
q + p = 17
Therefore, p+q = 17.

Round each decimal to the nearest one then subtract $3.85-$2.17
To round $6.375 to the nearest one, it becomes $6.38. To subtract $3.85-$2.17, the result is $1.68.
Explanation:To round decimal numbers to the nearest whole number, you will determine whether the decimal portion is closer to the previous or next whole number. If it is less than 0.5, you will round down, and if it is 0.5 or greater, you will round up. In this case, $6.375 is closer to $6.38, so you would round it up to $6.38.
To subtract decimals, you align the decimal points and subtract each place value from left to right. In this case, you would subtract $2.17 from $3.85:
$3.85
- $2.17
= $1.68
To round each decimal to the nearest one and then subtract $3.85 - $2.17, you start by rounding each number individually. $3.85 rounds to $4.00, and $2.17 rounds to $2.00. Once rounded, you then subtract the rounded numbers to find the total. So, it would be $4.00 - $2.00, which equals $2.00.
