To solve this problem, we need to use the formula for the area of a rectangle, which is length times width. We can set up the formula as follows:

Area = length * width

Since we know that the width is 7 greater than ⅔ the length, we can represent the width as follows:

width = ⅔ * length + 7

We can substitute this expression for the width in the area formula to get the following:

Area = length * (⅔ * length + 7)

We are given that the area of the rectangle must be 172, so we can set up the following equation:

172 = length * (⅔ * length + 7)

To solve for the length of the rectangle, we can first distribute the length on the right-hand side of the equation, like this:

172 = length * ⅔ * length + 7 * length

We can then combine like terms on the right-hand side of the equation to get the following:

172 = ⅔ * length^2 + 7 * length

To solve for the length, we can use the quadratic formula, which is as follows:

length = (-b +/- sqrt(b^2 - 4ac)) / 2a

In this case, a = ⅔, b = 7, and c = -172. Plugging these values into the quadratic formula, we get the following:

length = (-7 +/- sqrt(49 - 4 * ⅔ * -172)) / 2 * ⅔

Simplifying this expression, we get the following:

length = (-7 +/- sqrt(49 + 576)) / ⅓

We can further simplify this expression by calculating the value of the square root, like this:

length = (-7 +/- sqrt(625)) / ⅓

Simplifying again, we get the following:

length = (-7 +/- 25) / ⅓

To find the final value of the length, we need to calculate the two possible values of the square root, which are 25 and -25. Plugging these values into the equation for the length, we get the following:

length = (-7 + 25) / ⅓ = 18 / ⅓ = 6

length = (-7 - 25) / ⅓ = -32 / ⅓ = -10

Since the length of a rectangle must be positive, we can discard the negative value and only consider the value of 6. This means that the length of the rectangle is 6, and the width is ⅔ * 6 + 7 = 11. Therefore, the dimensions of the rectangle are 6 by 11.

Answer:

angle b

Step-by-step explanation:

let's assume the triangle is a right angle triangle . either angle a or c can be equal to 60 degree

The value of θ is 60°.

Trigonometry is the study of the relationships between the angles and the lengths of the sides of triangles

The six trigonometric functions are sin, cos , tan , cosec , sec and cot

Let the angle be θ , that is;

sin θ = opposite / hypotenuse

cos θ = adjacent / hypotenuse

tan θ = opposite / adjacent

Thus, tan θ = sin θ / cos θ

cosec θ = 1/sin θ

sec θ = 1/cos θ

cot θ = 1/tan θ

Given data that the angle be represented as θ

Now , we are given that the angle θ is acute

Since Acute angles measure less than 90 degrees

So , the value of θ < 90°

when the value of sec θ = 2

cos θ = 1/sec θ

, cos θ = 1/2

The value of θ when cos θ is 1/2.

when the angle θ is 60°

Therefore ,

the value of θ is 60°

sec 60° = 2

Hence , The value of θ is 60°

Step-by-step explanation:

the probability that the first song played is a folk song is 9.1%.

What is probability?

By simply dividing the favorable number of possibilities by the entire number of possible outcomes, the probability of an occurrence can be determined using the probability formula. Because the favorable number of outcomes can never exceed the entire number of outcomes, the chance of an event occurring might range from 0 to 1.

Carter has 153 songs on a playlist. He's categorized them in the following manner:

20 country, 31 blues, 8 Latin American, 17 jazz, 26 rap, 14 folk, and 37 hip hop.

The number of folk songs is 14

P(folk) = number of folk songs/ total

= 14/ 153

1) Adam's monthly cash flows are:

2) I would save $300 monthly from the ending cash flow balance for retirement savings.

3) If Adam retires in 35 years and finds an IRA for 4.8%, the future value of their retirement account will be $326,070.43 when they retire.

4) In 35 years, Adam will deposit $126,000 in total to their IRA.

5) The accrued interest from the IRA will be $200,070.43.

The future value represents the balance in Adam's retirement savings account after 35 years of depositing $300 monthly at 4.8% interest.

The future value is computed by compounding the periodic deposits (present values).

Adam's total monthly earnings = $2,080 ($15 x 32 x 52 x 1/12)

Monthly Expenses:

Rent $650

Groceries $325 ($75 x 52 x 1/12)

Utilities $120

Car Insurance $118

Gasoline $130 ($30 x 52 x 1/12)

Miscellaneous $400

Total monthly expenses = $1,743

Ending cash flows = $337 ($2,080 - $1,743)

Retirement period = 35 years

IRA interest rate = 4.8%

Monthly savings = $300

N (# of periods) = 420 months (35 years x 12)

I/Y (Interest per year) = 4.8%

PV (Present Value) = $0

PMT (Periodic Payment) = $300

Results:

Future Value (FV) = $326,070.43

Sum of all periodic deposits = $126,000 ($300 x 420)

Answer:

[0, 799.95]

Step-by-step explanation:

First, we need to isolate the variable by subtracting 9 from both sides of the inequality:

20t + 9 - 9 ≤ 16,000 - 9

This gives us:

20t ≤ 16,000 - 9

Next, we can divide both sides of the inequality by 20 to isolate the variable:

20t / 20 ≤ (16,000 - 9) / 20

This simplifies to:

t ≤ 799.95

Finally, we need to express the solution in interval notation. Since the value of t cannot be negative, the solution is:

[0, 799.95]

Therefore, the solution to the inequality in interval notation is [0, 799.95].

For the rectangle, we have

Length = 5 ft and Width = 14 feet

For the circle, we have

Diameter = 14 ft - 4 ft - 4 ft

Evaluate

Diameter = 6 feet

Start by calculating the radius of the semicircle

So, we have the following representation

radius = Diameter/2

This gives

radius = 6/2

Evaluate

radius = 3

The area of the shape is then calculated as

Area = Length * WIdth + πr²/2

What is system of equations?

A set of one or more equations involving numerous variables is referred to as a system of equations. The variable mappings that satisfy all component equations are the solutions to systems of equations, or the points where the components of these equations intersect.

Let d be the number of adults and y be the number of students.

⇒ d + s = 500                   ..(1)

The number of adult tickets sold at $6.50 and the number of student tickets sold at $3.50 each.

⇒ 6.5d + 3.5s = 2050         ..(2)

From equation (1) d = 500 - s

Plug the value of d in equation (2)

6.5(500 - s) + 3.5s = 2050

3250 - 6.5s + 3.5s = 2050

3250 - 3s = 2050

3s = 3250 - 2050

3s = 1200

s = 400

Plug s = 400 in d = 500 - s

⇒  d = 500 - 400 = 100

Hence, there are 100 students and 400 adults.

Now,  at one performance there were three times as many student tickets sold as adult tickets.

⇒ s = 3d

3d - s = 0          ..(3)

d + s = 480       ..(4)

⇒ 4d = 480

     d = 120  Adults

Plug d = 120 in equation (4)

120 + s = 480

         s = 480 - 120

         s = 360 Students

The money earned from these 480 people is

120 * 6.5 + 360 * 3.5 = 780 + 1260 = $2040.

$2040 - $2040 = $10

Hence, the 480 tickets sold had a $10 fall in ticket sales.

Answer:

To simplify the given equation, we can start by using the rules of algebra to rearrange the terms and combine like terms on both sides of the equation. This gives us:

-x - (-4x - 6) = 6

We can then distribute the negative sign on the left side of the equation to get:

-x + 4x + 6 = 6

We can then combine like terms on the left side of the equation to get:

3x + 6 = 6

We can then subtract 6 from both sides of the equation to get:

3x = 0

We can then divide both sides of the equation by 3 to get the final result:

x = 0

Therefore, the simplified form of the given equation is x = 0.

New total non fiction books = 36 + 20 = 56

New total number of all books = 300 + 20 = 320

Thus;

New percentage of non fiction books = 56/320 * 100%

New percentage of non fiction books = 17.5%

The equations for parallel lines:

y = -1/2 x - 2  ----- y = -1/2 x + 6

y = 1/2 x + 4   ----- y = 1/2 x - 4

y = 2x -4       -----  y =2/1x + 2

y = 5x + 2     -----  y = 5x - 1

y = 1/5 x + 10 ----   y = 1/5 x + 3

What is slope of line?

A line's steepness can be determined by looking at its slope. Slope is calculated mathematically as "rise over run" (change in y divided by change in x).

If an equation in the form y = mx + c then m is the slope of the line.

Answer: (-1,1)

Step-by-step explanation:

since y is equal to 2x+3  you can sub 2x+3 into the y value of 12x+4y=-8

12x+4(2x+3)=-8

Multiply the numbers inside the parentheses using the distributive property

12x+8x+12=-8

Combine like terms

20x+12=-8

Isolate x by moving all other numbers to the right side

Subtract 12 on both sides

20x+12-12=-8-12

20x=-20

divide both sides by 20 to isolate and get the value of x

x=-1

Now that we know the x value substitute the value of x in any of the above equations. I am using y=2x+3

y=2(-1)+3

Multiply the numbers inside the parentheses

y=-2+3

y=1

The x value is -1, and the y value is 1.

Use them as coordinate points

(-1,1)

The solution to the given system of equations is the point (-1, 1) which is determined by the substitution method.

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

The system of equations is given as:

12x + 4y = −8

y = 2x + 3

To solve this system of equations using the substitution method, you can substitute the second equation into the first equation to eliminate one of the variables.

Substituting y = 2x + 3 into the first equation gives:

12x + 4(2x + 3) = -8

12x + 8x + 12 = -8

20x + 12 = -8

20x = -20

x = -1

Substituting this value of x back into the second equation gives:

y = 2(-1) + 3

y = -2 + 3

y = 1

Therefore, the solution to the system of equations is the point (-1, 1).
