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.

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.

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.

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.

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.

Hence, the sales price of the property was $136,053.

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)

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 quadrilateral is a polygon with 4 number of sides and 4 vertices. The measure of the ∠X is 104°.

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

∠X = 104°

Hence, the measure of the ∠X is 104°.

Without additional details it is not possible to solve for the measure of angle Z (mZX) in a kite. Kite properties and given angle measures are typically used to solve for unknown angles.

The question asks to find the measure of angle Z (mZX) in a kite. A property of a kite is that it has two pairs of adjacent sides that are equal. Another property is that the diagonals intersect at right angles. Furthermore, kites have one pair of opposite angles that are equal, known as the non-vertex angles.

If the kite diagram was provided with certain angles or relationships between the angles, we could use that information to calculate mZX. Typically, we would use the properties of the kite's angles and sides to form equations and solve for the unknown angle.

Without additional information provided, we cannot definitively solve for mZX. Usually, in the context of a geometry problem like this, one would apply the knowledge of geometric shapes, their properties, and other given information to solve for the unknown angle.

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).

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.

Hence, the correct answer would be an option (A).

Final answer:

The equation for finding the value of K when increased by 10 equals 24 is K + 10 = 24, and solving it results in K = 14.

Explanation:

A number K increased by 10" is represented by K+10.

"Is the same as" means equal to.

"24" is represented by 24.

Therefore, we can express this relationship as an equation where the left side represents "a number K increased by 10" and the right side represents "24."

The equation to represent the situation where a number K increased by 10 equals 24 is:

K + 10 = 24

This equation signifies that when the unknown number K is augmented by 10, the resultant value equals 24. It serves as a concise representation of the given condition, enabling the determination of K by solving the equation.

Through such algebraic manipulation, one can discern that the value of  K:

K = 24 - 10 = 14

Answer:

1.37

Step-by-step explanation:

First, we want to isolate the variable x. Do this by dividing both sides by 9:

[tex]\frac{9x^2}{9} =17/9[/tex]

[tex]x^{2} =17/9[/tex]

Now, square root both sides:

[tex]\sqrt{x^2}= \sqrt{17/9}[/tex]

x = [tex]\sqrt{17/9} =\sqrt{17}/3[/tex]

Finally, we can use a calculator to finish off the problem:

x = [tex]\sqrt{17}/3[/tex] ≈ 1.37

Hope this helps!

9x^2 = 17

Divide both sides by 9

X^2 = 17/9

Take the square root of both sides

X = sqrt(17/9) and -sqrt(17/9)

Simplify:

X = sqrt(17)/3 and -sqrt(17)/3
