A park has two rectangular, fenced playgrounds. The first playground has a perimeter of 160 feet. The second playground is twice as long and twice as wide as the first playground. Which of these could be the perimeter of the second playground in feet? pls help now ty
a. 640
b. 320
c. 240
d. 168
Answer:
So, the answer is (b) 320 feet.
Step-by-step explanation:
Let's call the length and width of the first playground "x".
The perimeter of the first playground is 160 feet, so 2 times the length plus 2 times the width is equal to 160:
2x + 2x = 160
Simplifying:
4x = 160
Dividing both sides by 4:
x = 40
So the length and width of the first playground are both 40 feet.
The second playground is twice as long and twice as wide as the first playground, so the length and width of the second playground would be 2 * 40 = 80 feet.
The perimeter of the second playground would then be 2 * 80 + 2 * 80 = 320 feet.
So, the answer is (b) 320 feet.

A circle has a circumference of 21.98 inches. What is the diameter of the circle? (Use
3.14 for )
Answer:
Step-by-step explanation:
The formula for the circumference of a circle is C = 2 * π * r, where r is the radius of the circle. We can find the radius of the circle by rearranging the formula to r = C / (2 * π).
Substituting the given values into the formula, we get:
r = 21.98 inches / (2 * 3.14) = 21.98 inches / 6.28 = 3.50 inches
The diameter of the circle is equal to twice the radius, so we can find the diameter by multiplying the radius by 2:
d = 2 * r = 2 * 3.50 inches = 7.00 inches.
To find the diameter of a circle with a given circumference, you can use the following steps:
Define the formula for the circumference of a circle: The circumference of a circle is given by the formula C = 2πr, where π (pi) is a mathematical constant approximately equal to 3.14, and r is the radius of the circle.
Substitute the given circumference into the formula: If the circumference of the circle is 21.98 inches, we can substitute that into the formula to get 21.98 = 2πr.
Solve for the radius: To solve for the radius, we can divide both sides of the equation by 2π: 21.98 / 2π = r. Using 3.14 for π, this gives us 21.98 / (2 * 3.14) = r, which can be simplified to r = 2.01 inches.
Calculate the diameter: The diameter of a circle is twice the radius, so the diameter can be calculated as 2 * r = 2 * 2.01 = 4.02 inches.
So, the diameter of the circle with a circumference of 21.98 inches is 4.02 inches.
Andrew collects coins. He collected a total of 150 coins. If 76% of the coins he collected were foreign, how many other coins did he collect?
With percentage=76% of foreign coins of total 150 coins, Other coins collected were 36.
What is the percentage?
In mathematics, a percentage is a statistic or ratio that may be expressed as a fraction of 100. To find the percentage of a number, divide it by its total and multiply by 100. Hence, the percentage represents one part of a hundred. The phrase % stands for one hundred percent. It is represented by the symbol "%".
Here are some instances of percentages:
10% is one-tenth of a fraction.20% is one-fifth of a share.25% is divided into quarters.Now,
Given that total coins=150
Foreign coins=76% of total
then other coins are 24% of total
so other coins=150*24/100
=72/2
=36
Hence,
Other coins collected were 36.

Use the rational zeros theorem to list all possible rational zeros of the following.
Answer:

Step-by-step explanation:
Given polynomial:
[tex]f(x)=-3x^3-5x^2+x-7[/tex]
Rational Root TheoremIf P(x) is a polynomial with integer coefficients and if p/q is a root of P(x), then p is a factor of the constant term of P(x) and q is a factor of the leading coefficient of P(x).
Possible p-values
Factors of the constant term: ±1, ±7
Possible q-values
Factors of the leading coefficient: ±1, ±3
Therefore, all the possible values of p/q:
[tex]\sf \dfrac{p}{q}=\dfrac{\pm1}{\pm1},\dfrac{\pm1}{\pm3},\dfrac{\pm7}{\pm1},\dfrac{\pm7}{\pm3}=\pm 1, \dfrac{\pm1}{\pm3},\pm 7, \dfrac{\pm7}{\pm3}[/tex]
Substitute each possible rational root into the function:
[tex]x=-1 \implies f(-1)=-3(-1)^3-5(-1)^2+(-1)-7=-10[/tex]
[tex]x=1 \implies f(1)=-3(1)^3-5(1)^2+(1)-7=-14[/tex]
[tex]x=-7 \implies f(-7)=-3(-7)^3-5(-7)^2+(-7)-7=770[/tex]
[tex]x=7 \implies f(7)=-3(7)^3-5(7)^2+(7)-7=-1274[/tex]
[tex]x=-\dfrac{1}{3} \implies f\left(-\dfrac{1}{3}\right)=-3\left(-\dfrac{1}{3}\right)^3-5\left(-\dfrac{1}{3}\right)^2+\left(-\dfrac{1}{3}\right)-7=-\dfrac{70}{9}[/tex]
[tex]x=\dfrac{1}{3} \implies f\left(\dfrac{1}{3}\right)=-3\left(\dfrac{1}{3}\right)^3-5\left(\dfrac{1}{3}\right)^2+\left(\dfrac{1}{3}\right)-7=-\dfrac{22}{3}[/tex]
[tex]x=-\dfrac{7}{3} \implies f\left(-\dfrac{7}{3}\right)=-3\left(-\dfrac{7}{3}\right)^3-5\left(-\dfrac{7}{3}\right)^2+\left(-\dfrac{7}{3}\right)-7=\dfrac{14}{9}[/tex]
[tex]x=\dfrac{7}{3} \implies f\left(\dfrac{7}{3}\right)=-3\left(\dfrac{7}{3}\right)^3-5\left(\dfrac{7}{3}\right)^2+\left(\dfrac{7}{3}\right)-7=-70[/tex]
As f(p/q) ≠ 0, none of the possible rational roots are actual roots of the given polynomial.

The new triangle with vertices A'(0, 6), B'(12, -6), and C'(6, -6) would be larger than the original triangle by a factor of 120%.
What is a transformation?A point is transformed when it is moved from where it was originally to a new location. Translation, rotation, reflection, and dilation are examples of different transformations.
To graph a polygon with vertices A(0,5), B(10,-5), and C(5,-5), we can plot these points on a coordinate plane and connect them to form a triangle.
Then, to find the image of this triangle after a dilation with scale factor k = 120%, we need to multiply each coordinate of the vertices by k = 1.2.
For vertex A, the new coordinates would be (0 × 1.2, 5 × 1.2) = (0, 6).
For vertex B, the new coordinates would be (10 × 1.2, -5 × 1.2) = (12, -6).
For vertex C, the new coordinates would be (5 × 1.2, -5 × 1.2) = (6, -6).
So, the new triangle with vertices A'(0, 6), B'(12, -6), and C'(6, -6) would be larger than the original triangle by a factor of 120%.

Approximate the area between the x-axis and the graph of f(x) = x² + 4 over the interval [0, 2]
by calculating the sum of the areas of 4 rectangles with equal widths along the interval. The
rectangles should be placed on the x-axis and the heights should be the function values at the right
endpoint of each subinterval, as shown below.
Answer:
To approximate the area between the x-axis and the graph of f(x) = x^2 + 4 over the interval [0, 2], we can use the right rectangle method, where the heights of the rectangles are given by the value of the function at the right endpoint of each subinterval. If we divide the interval [0, 2] into 4 equal subintervals of width 0.5, the right endpoint of each subinterval would be 0.5, 1, 1.5, 2.
The height of the first rectangle would be f(0.5) = 0.5^2 + 4 = 4.25, the height of the second rectangle would be f(1) = 1^2 + 4 = 5, the height of the third rectangle would be f(1.5) = 1.5^2 + 4 = 6.25, and the height of the fourth rectangle would be f(2) = 2^2 + 4 = 8.
The sum of the areas of the rectangles is equal to (0.5) × (4.25 + 5 + 6.25 + 8) = (0.5) × 24 = 12.
So, the approximate area between the x-axis and the graph of f(x) = x^2 + 4 over the interval [0, 2] is 12.

In mathematics, an equation is a statement that two mathematical expressions are equal. The expressions can contain variables, constants, mathematical operations, and functions. An equation can be used to represent a relationship between two or more variables, and it is often used to solve problems by finding the values of the variables that satisfy the equation.
Equations can be represented in different forms, such as algebraic equations, differential equations, integral equations, and partial differential equations. Algebraic equations are the most common type of equations, and they involve algebraic operations such as addition, subtraction, multiplication, and division.
Equations can be classified according to their degree, which is the highest power of the variable in the equation. Linear equations are those with a degree of one, and they can be represented by a straight line on a graph. Quadratic equations have a degree of two, and they can be represented by a parabolic curve. Higher degree equations are generally more complex, and they may not have a simple geometric representation.
For x = -4, y = 4(-4) - 3 = -19 and z = -18, so y is greater.
For x = 2, y = 4(2) - 3 = 5 and z = 6, so z is greater.
For values of x where z is greater than y, we need to compare the values of z and y for each x value in the table.
At x = 3, y = 4(3) - 3 = 9 and z = 9, so they are equal.
At x = 7, y = 4(7) - 3 = 25 and z = 27, so z is greater.
At x = 10, y = 4(10) - 3 = 37 and z = 35, so z is not greater than y.

Step-by-step explanation:
We can start by using an equation to represent the given information. Let's call the number p, and the number k, then:
k = (1/5)p + 6
So, "six more than one-fifth of a number p is equal to a number k" can be represented mathematically as k = (1/5)p + 6. To find the value of p, we can solve for p:
p = 5k - 30
So, p is equal to 5 times the value of k minus 30.

Lowell's verbal representation of the equation y = x - 25 is "y is equal to x minus 25".
This verbal representation accurately describes the equation. In the equation, y is the dependent variable and x is the independent variable. The equation says that y is equal to x minus 25, which means that for every value of x, there is a corresponding value of y that is x minus 25.
So, Lowell has completed the task correctly.
