Answer:

4 feet and 4 inches of fringe

Step-by-step explanation:

The length and width of a square are equal to each other

Let x = length of a side of a square

Area of a square = Length × Width

                            = (x inches) × (x inches)

                            = [tex]x^{2}[/tex] [tex]in^{2}[/tex]

The area of the square placemat = 169 [tex]in^{2}[/tex]

∴                                            [tex]x^{2} in^{2}[/tex]  = 169 [tex]in^{2}[/tex]

Taking the square root on both sides of the equation to get rid of the square:

                                             x inches = [tex]\sqrt{169}[/tex] inches

                                            x inches = [tex]\sqrt{169}[/tex] inches

   ([tex]\sqrt{169} =[/tex] ± 13. However, the negative value will be rejected since the length of a side CANNOT be negative)    

        So, x = 13 inches

This means the perimeter of the square = (13 + 13 + 13 + 13) inches

                                                                   = 52 inches

∴ 52 inches of fringe will be needed by Sally

Unit conversion:

                                                   I foot = 12 inches

                                      ∴          y feet = 52 inches

     Cross-multiplication is applied:

                       (y feet)(12 inches) = (52 inches)(1 foot)

Isolating y and making it the subject of the formula:

                                   y feet = [tex]\frac{(52 inches)(1 foot)}{12 inches}[/tex]

Inches in the numerator and denominator will cancel each other out completely:

                                  y feet = [tex]\frac{52}{12}[/tex] feet

Applying long division:

The highest quotient to be multiplied by 12 to give a number, which is closest to 52 but still less than 52. 12×4 = 48. Therefore, the quotient is 4 and the remainder is 4.

∴ 52 inches = 4 feet and 4 inches

The required final balance on interest rate of 6%per annul is  $354.

The fee you pay to borrow money or the fee you charge to lend money is called interest. The most common way to represent interest is as a yearly percentage of the loan amount. The interest rate on the loan is known as this percentage.

Simple interest is calculated as:

I = P * r * t

where I is the interest, P is the principal (initial investment), r is the annual interest rate as a decimal, and t is the number of years.

So, in this case:

I = 300 * 0.06 * 3

I = 300 * 0.06 * 3 = 54

The final balance would be the sum of the initial investment and the interest earned:

Final balance = P + I

Final balance = 300 + 54

Final balance = 300 + 54 = 354

Rounded to the nearest cent, the final balance is $354.

Answer:

  ∆ABC is an isosceles triangle

Step-by-step explanation:

You have a triangle ABC such that the angle bisector of angle B also bisects side AC.

An angle bisector divides the sides of the triangle proportionally. This means the sides BA and BC will have the same ratio as the segments of AC on either side of the point of intersection with the angle bisector.

Since AC is bisected, that means those segments are congruent, hence sides BA and BC are congruent. The triangle is isosceles.

What is inequality?

An inequality is a relation that compares two numbers or other mathematical expressions in an unequal way. The majority of the time, size comparisons between two numbers on the number line are made. Different types of inequalities are represented by a variety of notations, including:

The symbol a < b indicates that an is smaller than b.

When a > b is used, it indicates that an is bigger than b.

Here, we have

Given: -4(x + 7) < 3(x - 2)

To find out which inequality is equivalent, you solve for x.

-4(x+7) < 3(x-2): distribute variables

-4x-28 < 3x-6: Add 6 to both sided

-4x-22 < 3x: add 4x to both sides

-22 < 7x

The required demand function and revenue per ticket are p(x) = -0.4 * (x - 21000) + $9 and  $9.

a) To find the demand function p(x), we can use the two data points: (21000, $9) and (26000, $7). To find the slope of the demand function, we can use the formula:

slope = (change in price) / (change in attendance)

Plugging in the two data points, we get:

slope = ($9 - $7) / (26000 - 21000) = -$2 / 5000 = -0.4

To find the y-intercept, we can use either data point and the slope we just found. Let's use the first data point:

p(x) = slope * (x - 21000) + $9

Now we have our demand function:

p(x) = -0.4 * (x - 21000) + $9

b) To maximize revenue, we need to find the price that will result in the maximum number of tickets sold. This is equal to the price that corresponds to the peak of the demand function, or the maximum value of x for which p(x) is decreasing. To find this, we can take the derivative of the demand function and set it equal to zero:

dp/dx = -0.4 = 0

x = 21000

So the maximum revenue is obtained by selling 21000 tickets at the price of $9 each, for a total revenue of $189,000. To maximize revenue, the ticket price should be set at $9.

Answer:

Step-by-step explanation:The equation for the nth term of an arithmetic sequence is given by:

an = a1 + (n-1)d

Where:

a1 is the first term of the sequence

d is the common difference

n is the number of the term we want to find

Using the given information, we have:

a1 = -9 and d = 2

Plugging these values into the formula, we get:

an = -9 + (n-1)2

To find the 12th term of the sequence:

n = 12

an = -9 + (12-1)2

an = -9 + 11 * 2

an = -9 + 22

an = 13

So the 12th term of the sequence is 13.

A interaction between two terms or concepts that is neither equal in mathematics is referred to as an inequality. Consequently, inequity results from imbalance. In algebra, an inequality establishes the connection between two non-equal numbers. Egality and inequalities are not the same. Use the not comparable symbol most usually when two components are really not equal (). Values of any size can be contrasted using a variety of inequalities. By changing the two aspects until only the variables are left, many straightforward inequalities can be solved. But, a variety of factors support inequality: Both sides' 0 are split or added. Exchange the left and the right.

Problem 1

L = length

P = perimeter of the rectangle

P = 2L+2W

P = 20

2L+2W = 20

L+W = 10 after dividing everything by 2.

L = 10-W

area = length*width

A = L*W

A = (10-W)*W

A = -W^2 + 10W

Let x replace W for a temporary basis.

If we graphed y = -x^2+10x, then we'd see the highest point occurs at (5, 25). This means a width of 5 meters leads to the largest area of 25 square meters.

The length would be L = 10-W = 10-5 = 5 meters as well.

It turns out that a 5 meter by 5 meter square is the best choice when trying to max out this rectangle's area.

Problem 2

The results we got from the previous section was that a 5 by 5 square will max out the area.

If we allowed non-whole numbers into the mix, then it wouldn't change the previous answer. The best choice is still that 5 by 5 square.

The outcomes for the event of rolling a number greater than 5 is 1.

Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event.

We know that, probability of an event = Number of favourable outcomes/Total number of outcomes

Given that, a number cube with faces labeled from 1 to 6 will be rolled once.

Now, sample space is {1, 2, 3, 4, 5, 6}

Total number of outcomes =6

Number of favourable outcomes =1
