Final answer:
The area of the larger square is four times the area of the smaller square, as the side lengths are doubled, resulting in the area increasing by the square of the factor of increase (2^2 = 4).
Explanation:
When Marta has a square with a side length of 4 inches, and she has a second square with dimensions that are twice as large, the area of the larger square can be found by squaring the ratio of the side lengths. In this case, the larger square will have side lengths of 8 inches because they are twice as long. To determine how the area of the larger square compares to the area of the smaller square, we can use the formula for the area of a square, which is side length squared (s^2).
The area of the smaller square is 4 inches * 4 inches = 16 square inches. If we double the side length to get the larger square, its sides will be 8 inches, so its area will be 8 inches * 8 inches = 64 square inches. Therefore, the area of the larger square will be four times the area of the smaller square because 64 square inches is four times 16 square inches (4^2 = 16, which means four times more area).
n a newspaper, it was reported that yearly robberies in Springfield were down 20% to 176 in 2011 from 2010. How many robberies were there in Springfield in 2010?
Answer: There were 220 robberies in Springfield in 2010
Step-by-step explanation: If the robberies were reported to be down 20% and the new figure is 176, it simply means the figure 176 depicts 80% (or 0.8) of the figure from year 2010.
We shall take the figure in year 2010 as x, which is 100% (or 1.0) and year 2011 is 176 which is 80% (or 0.8). What we now have is;
176/x = 0.8
176/x = 4/5
By cross multiplication we now have;
(176 x 5)/4 = x
880/4 = x
220 = x
Therefore, there were 220 robberies in Springfield in 2010
Answer: There were 220 robberies in Springfield in 2010.
Step-by-step explanation:
Hi, to answer this question we have to write an equation with the information given.
Since the robberies decreased 20%, it means that 2011 are robberies are the 80% (100%-20%) of the 2010 robberies (x).
So if we multiply the yearly robberies in 2010 (x) by 0.8 (decimal form, 80/100=0.8) , we obtain the number of yearly robberies in 2011 (176).
x (0.80) = 176
Solving for x
x = 176/0.8
x = 220 robberies (2010)

Which number is a rational number? √25 √32 √50 √63
Answer:
√25
Step-by-step explanation:
√25 is a perfect square and simplifies to 5.
A rational number is any number that can be expressed as a quotient or fraction of two integers, with the denominator not equal to zero. Among the options, √25 is the only rational number as it equals to 5 which can be expressed as a fraction (5/1). The others are not rational as their square roots are not exact whole numbers.
Explanation:The question is asking which number among the given options is a rational number. Rational numbers can be any number that can be expressed as a quotient or fraction p/q of two integers, with the denominator q not equal to zero. In this case, we need to find out which of the square root numbers is rational.
The square of √25 is 25, so √25 equals to 5 which is surely a rational number, because it can be expressed as a fraction 5/1. So, the rational number from the given options is √25.
The square roots of the other numbers are not exact whole numbers and therefore aren't rational numbers. For example, √32, √50, and √63 are approximately 5.66, 7.07, and 7.94 respectively, and these cannot be expressed as exact fractions.

A broker pays his salespeople 25 percent of the commission for listing a property and 40 percent of the
commission for selling it. If the commission rate is 6 percent and a salesperson received $3,265.28 on a
property that he sold, what was the sales price? (Round answer to nearest dollar.)
Answer: The sales price was $83,725
Step-by-step explanation: The commission rate for selling the property has been given as 6 percent of the sales price.
If the salesperson received a total of 3265.28, (which is 25% + 40% = 65% of the commission) then that means he has received the amount calculated as follows;
(3265.28/x) = 65/100
(Where x is the commission earned)
By cross multiplication we now have
(3265.28 x 100)/65 = x
5023.5 = x
Having calculated the commission as $5023.5, we remember that the commission rate is 6%, and hence, to calculate the sales price (which is 100%) we take the following steps;
(5023.5/y) = 6/100
(Where y is the total sales figure)
By cross multiplication we now have
(5023.5 x 100)/6 = y
83725 = y
Therefore, the sales price was, $83,725
To find the sales price of a property based on the commission received, divide the commission earnings by the percentage commission for selling the property, then divide that total by the overall commission rate. Rounding to the nearest dollar, the sales price was $136,053.
Explanation:The subject of this question is Mathematics, specifically pertaining to business and commission calculations. The problem involves determining the sales price of a property based on the commission received by a salesperson.
Understand that a salesperson received $3,265.28, which represents 40% of the commission for selling a property.Calculate the total commission by dividing the salesperson's earnings by the selling commission percentage: $3,265.28 ÷ 0.40 which equals $8,163.20 total commission.Find the sales price of the property by dividing the total commission by the commission rate: $8,163.20 ÷ 0.06.Calculate the sales price: $8,163.20 ÷ 0.06 = $136,053.33.Round the sales price to the nearest dollar, which gives us $136,053.Hence, the sales price of the property was $136,053.
The radius of a circle is 3 m. Find its area to the nearest tenth
Answer:
28.26
Step-by-step explanation:
3^2*3.14 = 28.26
To find area you square the radius and then multiply by 3.14 or π pi
Rounded to the nearest tenth, the area of the circle is approximately 28.3 square meters.
To find the area of a circle, we can use the formula:
Area = π (radius)²
Given that the radius is 3 meters, we substitute this value into the formula:
Area = π(3²)
Area = 9π
Since we are asked to round the area to the nearest tenth, we can approximate the value of π as 3.14:
Area ≈ 3.14 x 9
Area ≈ 28.26
Rounded to the nearest tenth, the area of the circle is approximately 28.3 square meters.
The area of a circle is calculated by multiplying the square of its radius by the mathematical constant π (pi). In this case, with a radius of 3 meters, the area is approximately 28.3 square meters. Rounding the decimal to the nearest tenth gives us the final result of 28.3 square meters.

What is a quadrilateral?A quadrilateral is a polygon with 4 number of sides and 4 vertices. A few examples of a quadrilateral are square, rectangle, rhombus, parallelogram, etc.
Given a scenic overlook which extends over a ravine is shaped like a kite. Since in a kite the measure of all the angles is 360°, also, the measure of the angle formed by the two non-equal sides is equal. Therefore, the measure of the two angles that will be equal is ∠X and ∠Z.
Further, the sum of the measure of all the angles can be written as,
∠X + ∠Y + ∠Z + ∠W = 360°
∠X + 40° + ∠X + 112° = 360°
2∠X = 360° - 112° - 40°
2∠X = 208°
∠X = 208°/2

Find the volume of the composite figure to the nearest whole number. The cylinder in the middle of the prism is hollow and should not be included in the volume.
The nearest whole number, the volume of the composite figure is 1140 in^3.
The composite figure consists of two rectangular prisms. The first prism has dimensions 8 in. x 4 in. x 18 in., and the second prism has dimensions 10 in. x 4 in. x 18 in.
To find the volume of the composite figure, we need to subtract the volume of the hollow cylinder from the volume of the two rectangular prisms.
The volume of a rectangular prism is calculated as follows:
Volume = length x width x height
The volume of the first rectangular prism is therefore:
Volume = 8 in. x 4 in. x 18 in. = 576 in^3
The volume of the second rectangular prism is therefore:
Volume = 10 in. x 4 in. x 18 in. = 720 in^3
The volume of a cylinder is calculated as follows:
Volume = π * radius^2 * height
Since the cylinder in the middle of the prism is hollow, we only need to consider the volume of the cylinder wall. The radius of the cylinder is 1 in., and the height of the cylinder is 18 in. Therefore, the volume of the cylinder wall is:
Volume = π * 1 in.^2 * 18 in. = 56.52 in^3
The total volume of the composite figure is therefore:
Volume = (576 in^3 + 720 in^3) - 56.52 in^3 = 1140.48 in^3
To the nearest whole number, the volume of the composite figure is 1140 in^3.

A: P=4x+16
B: P=2x+8
C: P=x+8
D: P=x^2+8x-9
Answer:
A
Step-by-step explanation:
P = 2 (W+L)
P = 2 (x+9+x-1)
P = 2 (2x+8)
P = 4x+16
The equation P = 4x+16 describes the perimeter, P, of the rectangle in terms of x. The correct answer would be option (A).
What is the perimeter of the rectangle?The perimeter of a rectangle is defined as the addition of the lengths of the rectangle's four sides.
The perimeter of a rectangle = 2(L+W)
Where W is the width of the rectangle and L is the length of the rectangle
A rectangle has a length of x + 9 and a width of x - 1.
P = 2 (L + W) ....(i)
Substitute the values of L = x + 9 and W = x-1 in the above equation,
P = 2 (x+9+x-1)
P = 2 (2x+8)
P = 4x+16
Thus, the equation P = 4x+16 describes the perimeter.
