Answers

Inequalities are used to represent unequal expressions.

The inequality is [tex]24 + 8R \ge 100[/tex]

The given parameters are:

[tex]Paid = 24[/tex]

[tex]Rolls = 12[/tex]

[tex]Cost = 8[/tex] --- the unit cost per roll.

Assume the number of additional roll is R.

So, the total number of sushi is:

[tex]Total=Paid + Cost \times R[/tex]

This gives

[tex]Total=24 + 8\times R[/tex]

Multiply 8 and R

[tex]Total=24 + 8R[/tex]

The sushi needed is at least 100.

This implies that:

[tex]Total \ge 100[/tex]

So, we have:

[tex]24 + 8R \ge 100[/tex]

Hence, the inequality is [tex]24 + 8R \ge 100[/tex]

Terry and Jim have two car loans totaling $ 26,004.
One loan has an annual percentage rate (APR) of 3.1 % and the other has an APR of 7%.
If the total interest they paid after one year is $1,481.25, what is the amount owed on each car?
(1 = PRT. Note t = 1 year).
Answer needed right away!! With explanation

Answers

The annual percentage rate is the interest rate for payment for the car

loan.

The mount owed on the car with an APR of 3.1% is approximately $8,693.08.

The mount owed on the car with an APR of 7% is approximately $17,310.92.

The given parameters are;

The amount of loan Terry and Jim have = $26,004

The annual percentage rate (APR) on one loan = 3.1 %

The annual percentage rate (APR) on the other loan = 7 %

Total interest paid after one year = $1,481.25

Required:

The amount owed on each car

Solution:

Let X represent the loan, with 3.1% APR, we have;

The other loan with 7% APR = 26,004 - X

Therefore;

0.031·X + 0.07·(26,004 - X) = 1,481.25

0.031·X + 1,820.28 - 0.07·X = 1,481.25

1,820.28 - 1,481.25 = 0.07·X - 0.031·X = 0.039·X

339.03 = 0.039·X

[tex]X = \dfrac{339.03}{0.039} \approx 8693.08[/tex]

Therefore;

The amount owed on the car with an APR of 3.1%, X ≈ $8,693.08

Therefore;

The amount owed on the car with an APR of 7% ≈ 26,004 - 8693.08 =

17310.92.

The amount owed on the car with an APR of 7% ≈ $17,310.92

The perimeter of a rectangle is 20x -18 feet. If the width of the rectangle is 3x -1 feet, write an expression that can represent the length of the rectangle.

Answers

Answer:

l = 7x - 9

Step-by-step explanation:

The length of the rectangle is represented by the expression "7x - 9".

What is the perimeter of the rectangle?

The perimeter of a rectangle is defined as the addition of the lengths of the rectangle's four sides.

The perimeter of a rectangle is given by the formula:

Perimeter = 2 (length + width)

Therefore, we can set up the equation:

20x - 18 = 2 (length + (3x - 1))

Expanding the parentheses and combining like terms, we get:

20x - 18 = 2 × length + 6x - 2

Moving all the terms to one side, we get:

14x - 18 = 2 × length

Dividing both sides by 2, we get:

7x - 9 = length

Thus, the rectangle's length is expressed by the expression "7x - 9".

During the NCAA basketball tournament season, affectionately called March Madness, part of one team's strategy is to foul their opponent if his free-throw shooting percentage is lower than his two-point field goal percentage. Juan's free-throw shooting percentage is lower and is only 53.5%. After being fouled he gets two free-throw shots each worth one point. Calculate the expected value of the number of points Juan makes when he shoots two free-throw shots.

Answers

Using the binomial distribution, the expected value of the number of points Juan makes when he shoots two free-throw shots is 1.07.

For each shot, there are only two possible outcomes, either Juan makes it, or he misses it. The probability of making a shot is independent of any other shot, hence, the binomial distribution is used to solve this question.

Binomial probability distribution

Probability of exactly x successes on n repeated trials, with p probability, and the expected value is:

[tex]E(X) = np[/tex]

In this problem:

Two shots, hence [tex]n = 2[/tex]He makes 53.5% of the shots, hence [tex]p = 0.535[/tex].

Then:

[tex]E(X) = np = 2(0.535) = 1.07[/tex]

Your parents decide to build a rectangular pool in your backyard. They determine that the length of the pool should be 15 feet longer than the width.

Answers

The area of the pool is the amount of space it occupies

The expression for the area and the perimeter are [tex]\mathbf{A = 15x + x^2}[/tex] and  [tex]\mathbf{P = 4x +30}[/tex], respectively

Let the dimension of the pool be x and y, where x represents width and y represents length.

So, the relationship between the width and the length is given as:

[tex]\mathbf{y = 15 + x}[/tex]

The area of the pool would be:

[tex]\mathbf{A = xy}[/tex]

Substitute 15 + x for y

[tex]\mathbf{A = x(15 + x)}[/tex]

Open bracket

[tex]\mathbf{A = 15x + x^2}[/tex]

And the perimeter of the pool would be

[tex]\mathbf{P = 2(x + y)}[/tex]

Substitute 15 + x for y

[tex]\mathbf{P = 2(x +15 + x)}[/tex]

[tex]\mathbf{P = 2(2x +15)}[/tex]

Open brackets

[tex]\mathbf{P = 4x +30}[/tex]

Hence, the expression for the area and the perimeter are [tex]\mathbf{A = 15x + x^2}[/tex] and  [tex]\mathbf{P = 4x +30}[/tex], respectively
