Answer:

30 feet by 18 feet

Step-by-step explanation:

Area = length * width

A  = x*w

w = x - 12

A = 540 sq. ft

540 = x * (x -12)

x*x - 12x - 540 = 0

x*x - 12x  + 36  - 36 - 540 = 0

(x - 6)^2  -  576 = 0

x - 6 = 24

or x -6 = -24

x = 30  or x = -18

w = 30 - 12 = 18

30 ft by 18 ft

The solution to the equation -4x + 1 = x + (-4) using algebra tiles is x = 1

An equation is an expression that shows the relationship between two or more numbers and variables.

Given the equation:

-4x + 1 = x + (-4)

Add 4 positive x-tiles to both sides and create zero pairs:

-4x + 1 + 4x = x + (-4) + 4x

1 = 5x - 4

Add 4 positive unit tiles to both sides and create zero pairs:

1 + 4 = 5x - 4 + 4

5x = 5

Divide the unit tiles evenly among the x-tiles:

5x/5 = 5/5

x = 1

Answer:

Ashley's remaining available credit after her first purchase is $1025.00

Step-by-step explanation:

Here we are told that the borrower with the lower credit score will be charged $50.00 fee after the first purchase

Therefore, we have

Credit score Andrea = 895

Credit score for Ashley = 768

Therefore, Ashley has the lower credit score hence after her first purchase of a $425.00 Coach bag, we have

Available credit = Initial balance - Purchase - Charges

∴ Available credit = $1,500.00 - ($425.00 + $50.00) = $1025.00

Therefore, Ashley's remaining available credit after she purchases the $425.00 Coach bag = $1025.00.

Question:

Which three-dimensional figures have lateral faces that are polygons? check all that apply.

- cones

- cylinders

- hemispheres

- prisms

- pyramids

- spheres

Answer:

The correct choices are;

- prisms and

- pyramids

Step-by-step explanation:

A polygon is a figure closed or bounded with several straight line segments and polygons are named based on how many sides, side size and sizes of angles that they have present.

A three sided polygon for example is called a triangle

A lateral face are the faces of a prism except the base

Based on the definitions, we note that out of the options, only prisms, and pyramids have lateral faces that are made up entirely of straight line segments, hence polygons. Therefore, the correct choices are prisms and pyramids.

Actually the correct is Cylinders, Prisms, and Pyramids. I just did it

Answer:

The factored from of the equation is (x+4)(x-6)=0.

Step-by-step explanation:

When solving this problem, we need to find the factored form of this problem. Remember that in factored form, the right-hand side of the equation must equal to 0.

We can simply convert the left-hand side to standard form first:

(x-4)(x+2)=16 --> x²-2x-8= 16.

Now, to set the right-hand side of the equation to 0, we must subtract -16 from both sides:

x²-2x-24=0.

Now, if we convert this to factored form, we will get:

(x+4)(x-6)= 0.

All of the other statements are false. This is the only true statement.

What information do we have?

Cost of 1 kg vanilla beans = $600

Amount of vanilla beans bought by Jacque = 70 gram

121 + 22i - 1

Step-by-step explanation:

Expand:

(11 + i)² = (11 + i)(11 + i)

Note that:

i² = -1

Use FOIL method. Multiply first terms, outside terms, inside terms, then the last two terms:

(11)(11) = 121

(11)(i) = 11i

(i)(11) = 11i

(i)(i) = -1

Combine like terms:

121 + 11i + 11i - 1

121 + (11i + 11i) - 1

121 + 22i - 1

121 + 22i - 1 is your answer.

Answer:

81.85%

Step-by-step explanation:

We have the following information:

mean = m = 52000

standard deviation = sd = 12000

a = 40000

b = 76000

we need to find the probability between a and b, that is:

P (a <x <b) = P (40,000 <x <76000)

P [(40000 - m) / sd <(x - m) / sd <(76000 - m) / sd]

replacing

P [(40000 - 52000) / 12000 <z <(76000 - 52000) / 12000]

P (-1 <z <2)

P (z <= -1) - P (z <= 2)

We look for this value of z, in the attached table:

0.9772 - 0.1587

P = 0.8185

In other words, the probability is 81.85%

Answer:

y = -2x+2

Step-by-step explanation:

First we find the slope

m = (y2-y1)/(x2-x1)

   = (-2-4)/(2--1)

   = (-2-4)/(2+1)

   -6/3

  -2

We have the slope =-2

We can substitute it into the equation

y = mx+b where m is the slope and b is the y intercept

y =-2x+b

Use a point for x and y to solve for b

4 = -2(-1) +b

4 = 2+b

Subtract 2 from each side

4 -2 = -2+2+b

2 = b

We know m and b

y = -2x+2

Answer:

y = -2x + 2

Step-by-step explanation:

Slope: (-2-4)/(2--1) = -6/3 = -2

y - 4 = -2(x - -1)

y = -2x - 2 + 4

y = -2x + 2

Answer:

573.95 gallons/minute

Step-by-step explanation:

To find the amount of oil after 12 minutes you take the difference between the amount of oil that flows into the tank minus the the oil that flows aout the tanks. Then you have:

[tex]T(t)=F(t)-E(t)\\\\F(t)=t^2+\frac{1}{t+1}\\\\E(t)=\frac{ln(t+7)}{t+2}[/tex]

Being F(t) the flow that goes into the tank per minute, and E(t) the amount of oil that flows outside the tank per minute.

To know the total amount of F and E for t=12 you integrate these function:

[tex]\int_0^{12}F(t)dt=\frac{t^3}{3}+ln(t+1)|_{0}^{12}=578.56\frac{gallons}{minute}\\\\\int_{0}^{12}E(t)dt=\int_0^{12}[\frac{ln(t+7)}{t+2}]dt=4.61\frac{gallons}{minute}\\\\\int_0^{12}T(t)dt=578.56-4.61=573.95\frac{gallons}{minute}[/tex]

Answer:

Two solutions:

Adding 7 to the left and 0 to the right: 7920

Adding 2 to the left and 5 to the right: 2925

Step-by-step explanation:

The multiples of 45 always have as last digit 0 or 5, so the digit to the right of 92 has to be 0 or 5.

If we use 0 as the last digit, our options of multiples will be just 7920 (7920 = 45 * 176)

If we use 5 as the last digit, our option of multiples will be just 2925 (2925 = 45 * 65)

So we have just two solutions for this problem:

Adding 7 to the left and 0 to the right: 7920

Adding 2 to the left and 5 to the right: 2925

An angle measures 50° more than the measure of its supplementary angle. However, there are no angles that satisfy this condition.

An angle measures 50° more than the measure of its supplementary angle.

To solve for the measure of each angle, we can set up an equation:

Let x be the measure of the angle, and let y be its supplementary angle.

Since the sum of the measures of two supplementary angles is 180°, we can write the equation:

x = y + 50°

Substituting y + 50° for x in the equation, we get:

y + 50° = y

Subtracting y from both sides, we get:

50° = 0

Since there is no solution to this equation, it means that there are no angles that satisfy the given condition.

The smaller angle measures 65° while the larger angle measures 115°.

Let's denote the measure of the smaller angle as x degrees. Since the angles are supplementary, their sum must be 180 degrees. Thus, the measure of the larger angle will be (x + 50) degrees.

Using this information, we can form the following equation:

x + (x + 50) = 180

Simplify the equation:

2x + 50 = 180

Subtract 50 from both sides:

2x = 130

Divide both sides by 2:

x = 65

Therefore, the measures of the angles are:
