The perimeter of to similar polygon is 20 and 28. On side of the smaller polygon is 4. Find the corresponding side of the larger polygon
Final answer:
The corresponding side of the larger polygon is 5.6 units, found by setting up a proportion between the sides and the perimeters of the similar polygons. Scaling a square's side length by 2 makes its area 4 times larger, reflecting the square of the scale factor.
Explanation:
To solve the problem of finding the corresponding side of the larger polygon, we must use the property that the perimeters of similar polygons are proportional to their corresponding sides. Given that the perimeters are 20 for the smaller polygon and 28 for the larger one, we can set up a proportion to find the length of the corresponding side.
Let x be the length of the corresponding side in the larger polygon. The ratio of the perimeters is the same as the ratio of any pair of corresponding sides. Since we have a side of the smaller polygon being 4, we would set up the proportion as follows:
4 / x = 20 / 28
Cross-multiplying to solve for x, we have:
4 x 28 = 20 x x
112 = 20x
x = 112 / 20
x = 5.6
Therefore, the corresponding side of the larger polygon is 5.6 units. In the context of squares, when scaling a square by a factor of 2, the area increases by the square of the scale factor. If the smaller square has a side of 4 inches, the larger square will have a side length of 8 inches. Hence, the area of the larger square is 64 square inches (8x8), which is 4 times larger than the area of the smaller square which is 16 square inches (4x4).

The Campbell family has a disposable income of $60,000 annually. Assume that their marginal propensity to consume is 0.8 (the Campbell family spends 80% of new disposable income on consumption) and that their autonomous consumption spending is equal to $10,000. What is the amount of the Campbell family\'s annual consumer spending?,
The annual consumer spending of the Campbell family is $58,000.
Explanation:To calculate the amount of the Campbell family's annual consumer spending, you need to consider their autonomous consumption spending and their marginal propensity to consume. The autonomous consumption spending is $10,000, which means that even if their disposable income is zero, they will still spend $10,000. The marginal propensity to consume is 0.8, so for every additional dollar of disposable income, they will spend 80 cents. To find the annual consumer spending, you can use the formula: Consumer Spending = Autonomous Consumption Spending + (Marginal Propensity to Consume * Disposable Income). In this case, the disposable income is $60,000, so the annual consumer spending would be $10,000 + (0.8 * $60,000) = $58,000.

Nick’s parents purchased their first home in the 1980’s with a 30-year mortgage at 19.5%.
Final answer:
Using the formula for a fixed-rate mortgage payment, the monthly mortgage payment for Nick's parents, who bought a home for $125,000 with a 30-year mortgage at 19.5%, is calculated to be $2,037.40, making the answer A. $2,037.40.
Explanation:
To calculate the monthly mortgage payment for Nick's parents, who purchased their first home with a 30-year mortgage at 19.5% interest, we need to use the formula for a fixed-rate mortgage payment. The formula is:
M = P[r(1+r)ⁿ]/[(1+r)ⁿ⁻¹]
Where:
M is the total monthly mortgage payment.P is the principal loan amount.r is the monthly interest rate (annual rate divided by 12 months).n is the number of payments (loan term in years multiplied by 12 months).For this calculation:
P = $125,000r = 19.5% annual interest rate, which is 0.195/12 per month.n = 30 years x 12 months = 360 payments.We insert these numbers into our formula:
M = $125,000[0.195/12(1+0.195/12)³⁶⁰]/[(1+0.195/12)³⁶⁰⁻¹]
After calculating, we find that the monthly mortgage payment (rounded to two decimal places) would be $2,037.40.
Therefore, the answer is A. $2,037.40.

Please help!
The volume of a prism is calculated by multiplying the area of the base with the height of the prism. The correct answer is D. The area of the base times the height of the prism.
Explanation:The volume of a prism is calculated by multiplying the area of the base with the height of the prism. This means that out of the four options provided, the correct choice would be: D. The area of the base times the height of the prism.
For instance, if the area of the base of a rectangular prism is 30 square units and the height of that prism is 10 units, then the volume would be calculated as 30 (area of the base) * 10 (height of the prism) = 300 cubic units.

Alani uses 3/4 cup of pineapple juice to make one bread how much juice will she use to make 5 breads
To make five loaves of bread, Alani will use 3 3/4 cups of pineapple juice, calculated by multiplying the amount required for one loaf, which is 3/4 cup, by five.
To solve this, you multiply the amount of pineapple juice needed for one bread by the total number of breads.
Multiply the amount of juice for one bread by the number of breads: 3/4 cup × 5 = 15/4 cups.
Convert the improper fraction to a mixed number: 15/4 cups is equal to 3 3/4 cups.
Therefore, Alani will use 3 3/4 cups of pineapple juice to make five loaves of bread.
The angle between 0 and 2 π in radians that is coterminal with the angle 62 9 π in radians is
8π/9 is coterminal with 62π/9 and lies between 0 and 2π.
Given that, the angle between 0 and 2 π in radians that is coterminal with the angle 62π/9 in radians.
What is the coterminal with the angle?The coterminal angles are the angles that have the same initial side and the same terminal sides. We determine the coterminal angle of a given angle by adding or subtracting 360° or 2π to it.
To find a coterminal angle, add or subtract any multiple of 2π, that is
62π/9 - 2π = (62π-18π)/9
44π/9 - 2π = 26π/9
26π/9 - 2π = 8π/9
Therefore, 8π/9 is coterminal with 62π/9 and lies between 0 and 2π.
