Petra is raking leaves in her backyard. Petra’s backyard is rectangular and has an area of 476 square feet. One side of the backyard is 28 ft. How long is the other side?

Answer:

[tex]x=5+\frac{29}{z}-\frac{y}{z}[/tex]

[tex]y=5z+29-xz[/tex]

Step-by-step explanation:

Given: [tex](4z^2+7z-8)(-z+3)=-4z^3+xz^2+yz-24[/tex]; find x and y.

Let's start with finding x first. Let's distribute the left side of the equation.

[tex]-4z^3+5z^2+29z-24=-4z^3+xz^2+yz-24[/tex]

Let's move everything we can to the left side of the equation. Some things will cancel out.

[tex]5z^2+29z=xz^2+yz[/tex]

Now, let's move the term that includes [tex]x[/tex] to the left side of the equation. Everything else should be moved to the right.

[tex]-xz^2=-5z^2-29z+yz[/tex]

Let's get rid of the negative sign in front of [tex]x[/tex] by dividing both sides by -1.

[tex]xz^2=5z^2+29z-yz[/tex]

To get [tex]x[/tex] completely isolated, divide both sides by [tex]z^2[/tex].

[tex]\frac{xz^2}{z^2}=\frac{5z^2}{z^2}+\frac{29z}{z^2}-\frac{yz}{z^2}[/tex]

Simplify.

[tex]x=5+\frac{29}{z}-\frac{y}{z}[/tex]

Let's solve for y. We will start with the distributed and simplified equation to make it easier.

[tex]5z^2+29z=xz^2+yz[/tex]

Now, let's move the term that includes [tex]y[/tex] to the left side of the equation. Everything else should be moved to the right.

[tex]-yz=-5z^2-29z+xz^2[/tex]

Again, let's get rid of the negative sign in front of the [tex]y[/tex] by dividing both sides by -1.

[tex]yz=5z^2+29z-xz^2[/tex]

To isolate y, divide both sides by z.

[tex]\frac{yz}{z}=\frac{5z^2}{z}+\frac{29z}{z}-\frac{xz^2}{z}[/tex]

Simplify.

[tex]y=5z+29-xz[/tex]

(8c+5)(-2c-3)

Multiply each term together, then combine like terms:

8c * -2c = -16c^2

8c *-3 = -24c

5 * -2c = -10c

5 *-3 = -15

Now combine:

Answer:

y = - 2 or y = 6

Step-by-step explanation:

Given the 2 equations

y = 2x → (1)

y = x² - 3 → (2)

Substitute y = x² - 3 into (1)

x² - 3 = 2x ( subtract 2x from both sides )

x² - 2x - 3 = 0 ← in standard form

(x - 3)(x + 1) = 0 ← in factored form

Equate each factor to zero and solve for x

x - 3 = 0 ⇒ x = 3

x + 1 = 0 ⇒ x = - 1

Substitute these values into (1) for corresponding values of y

x = 3 : y = 2 × 3 = 6

x = - 1 : y = 2 × - 1 = - 2

Answer:

 A =  114 m²

Step-by-step explanation:

The formula for area of a trapezoid is

A = (1/2)(B + b)h   where B is the bottom base, b is the top base, and h is the height.  

We are given B = 11, b = 8, and h = 12, plug those values in and simplify

A = (1/2)(11 + 8)(12)

     A = (1/2)(19)(12)

          A = (19)(6)             (half of 12 is 6)

                A =  114 m²

Answer:

132 miles

Step-by-step explanation:

miles ran + miles to run = total miles

28 + miles to run = 160

Subtract 28 from each side

28-28 + miles to run = 160-28

miles to run = 132

He still need to run 132 miles

Answer:

132 mi

Step-by-step explanation:

since he ran 28 miles but he has to run 160 miles, he still has to run some miles. if we make the amount he still has to run x, we can do 28+x=160. now we can solve this by subtracting 28 on both sides to getx=132

             28+x=160

             -28      -28

        -------------------------

            x=132

Answer: ABC = 32 degrees

Step-by-step explanation:

We are already given the measurement of angle ACB, which is 58. And given AC is tangent to circle B we also know that BAC is 90 degrees.

So,

ABC = 180 - (BAC + ACB)

ABC = 180 - (90 + 58)

ABC = 180 - (148)

ABC = 32 degrees

Hope I could help :)

Answer:

ABC is equal to 32 degrees

Answer:

The value of y is -5

Step-by-step explanation:

we have

[tex]9x+2y=8[/tex] ------> equation A

[tex]7x+2y=4[/tex] ------> equation B

we know that

If x and y satisfy both equations, then (x,y) is the solution of the system of equations

Using a graphing tool

Remember that

The solution of the systems of equations is the intersection point both graphs

The intersection point is (2,-5)

therefore

The solution of the system of equations is the point (2,-5)

The value of y is -5

To find the value of y in the given system of equations, we can use the method of substitution.

To find the value of y in the system of equations 9x + 2y = 8 and 7x + 2y = 4, we can use the method of substitution. First, we solve one equation for one variable and substitute the expression into the other equation. In this case, we can solve the second equation for y: 7x + 2y = 4, y = (4 - 7x)/2. Now substitute this expression for y in the first equation: 9x + 2((4 - 7x)/2) = 8. Simplify and solve for x. Once we have the value of x, we can substitute it back into the second equation to find y.

Answer: [tex]120in^2[/tex]

Step-by-step explanation:

The formula that is used to calculate the area of a triangle is:

[tex]A_{(triangle)}=\frac{b*h}{2}[/tex]

Where the base of the triangle is b and the height of triangle  is h.

If the pennant has a base of 10 inches and a height of 24 inches, you know that:

[tex]b=10in\\h=24in[/tex]

As it is a triangular pennant, you can substitute the values of the base and the value of the height into the formula used to calculate the area of a triangle.

Answer:

The volume of the cone is 128π mm³ ⇒ answer (C)

Step-by-step explanation:

* Lets study the cone

- Its base is a circle

- Its height the perpendicular distance from its vertex to

 the center of the base

- The length of its slant height = √(h² + r²)

- The volume of the con is 1/3 the volume of the cylinder

∵ The volume of the cylinder = πr²h

∴ The volume of the cone = (1/3) πr²h

* In our problem:

- r = 4 mm

- h = 24 mm

∴ Its volume = (1/3) × π × (4)² × 24 = 128π mm³

* The volume of the cone is 128π mm³

The experimental probability of tossing tails in the given scenario is 0.4 or 40%, which is determined by dividing the number of tails (6) by the total number of tosses (15).

The student is asking to determine the experimental probability of tossing tails when a coin was tossed 15 times and resulted in 9 heads and 6 tails. Experimental probability is calculated by dividing the number of times an event occurs by the total number of trials. In this case, the coin landed as tails 6 times out of 15 tosses.

To find the experimental probability of tossing tails, use the formula:

Experimental Probability of Tails = Number of Tails / Total Number of Tosses

So, it would be:

Experimental Probability of Tails = 6 / 15

Experimental Probability of Tails = 0.4 or 40%

Answer:

A loan that you usually have to get from a bank to use specifically for paying for a car,which you later have to pay back

Step-by-step explanation:

A car loan is a type of secured loan, where we can say that the car we buy is collateral for the loan.

In case of failure of payment of loan, the lender can repossess the car and sell it to pay off the loan.

In other words, we can say the lender or banks purchase the car for us and gives us few years time to pay back that loan.

The loan is granted with interest rates, that one has to pay above the principle amount during the tenure of the loan.

Answer:

[tex]f^{-1}(x)=\dfrac{e^x}{3},\ x\in(-\infty,\infty),\ y>0[/tex]

Step-by-step explanation:

Consider the function [tex]f(x)=\ln 3x.[/tex] the domain of this function is x>0 and the range of this function is all real numbers. The inverse function has the domain all real numbers and the range y>0.

If

[tex]y=\ln 3x,[/tex]

then

[tex]3x=e^y,\\ \\x=\dfrac{e^{y}}{3}.[/tex]

Change x into y and y into x:

[tex]y=\dfrac{e^x}{3}.[/tex]

Thus, the inverse function is

[tex]f^{-1}(x)=\dfrac{e^x}{3}.[/tex]

ANSWER

[tex]{f}^{ - 1} (x) = \frac{ {e}^{x} }{3} [/tex]

EXPLANATION

The given logarithmic function is

[tex]f(x) = ln(3x) [/tex]

Let

[tex]y = ln(3x) [/tex]

Interchange x and y.

[tex]x = ln(3y) [/tex]

Solve for y.

[tex] {e}^{x} = {e}^{ ln(3y) } [/tex]

[tex] {e}^{x} = 3y[/tex]

Divide both sides by 3.

[tex] \frac{ {e}^{x} }{3} = y[/tex]

Therefore

[tex] {f}^{ - 1} (x) = \frac{ {e}^{x} }{3} [/tex]

The approximate percentage increase of the number of seats in the movie theater after the renovation is 34.8% when rounded to the nearest tenth of a percent.

To calculate the approximate percentage increase of the number of seats in the movie theater, we start by finding the difference in the number of seats before and after the renovation. We then divide this difference by the original number of seats and multiply by 100 to get the percentage increase.

Original number of seats = 138
New number of seats = 186
Increase in seats = New number of seats - Original number of seats
Increase in seats = 186 - 138 = 48

Next, we calculate the percentage increase:

Percentage increase = (Increase in seats \/ Original numbe of seats) x 100
Percentage increase = (48 \/ 138) x 100
Percentage increase \/= 34.7826...

When rounded to the nearest tenth of a percent, the percentage increase is approximately 34.8%.
