To convert 31,750 feet to miles, divide the number of feet by the number of feet per mile:

31,750 feet / 5,280 feet/mile = 6 miles

The frequency table is completed and the percent of the people who have exactly one sibling is 20.48%.

Relative frequency is found by dividing the frequency with the total number of values.

Cumulative frequency is calculated by adding the previous frequencies together.

(a) From the table,

Total number of people = 210

So, Total frequency = 210

Frequency of number of siblings as 4 = 210 - (43 + 43 + 41 + 43) = 40

Relative frequency = Frequency / Total frequency

Relative frequency of number of siblings as 2 = 0.1952

Cumulative frequency of number of siblings as 3 = 127 + 43 = 170

(b) Percent of people having exactly 1 sibling = (43 / 210) × 100

                                                                           = 20.48%

Hence the percent of people having exactly 1 sibling is 20.48%.

The product of a, b, and c is 27/8.

What is an expression?

In mathematics, an expression is a combination of numbers, symbols, and operators (such as +, -, ×, ÷, and parentheses) that represents a quantity or a mathematical relationship. Expressions can be simple or complex, depending on the number of terms and the complexity of the operations involved.

The given expression is

                                      [tex]\frac{6x^2y^{-1}}{\sqrt[4]{16x^5y^2} }[/tex]

To simplify the given expression and write it in the form of ax^by^c, we can start by using the properties of exponents and simplifying the numerator and denominator separately:

Numerator: [tex]6x^2y^(-1) = \frac{6x^2}{y}[/tex]

Denominator: [tex]\sqrt[4]{(16x^5y^2)} = (16x^5y^2)^{(1/4)} = 2x^{(5/4)}y^{(1/2)}[/tex]

Putting the simplified numerator and denominator together, we have:

[tex]\frac{6x^2y^{-1}}{\sqrt[4]{16x^5y^2}} = \frac{6x^2}{y} \cdot \frac{1}{2x^{5/4}y^{1/2}} = \frac{3}{\sqrt{2} \cdot x^{3/4}y^{3/2}}[/tex]

Now we can see that the given expression can be written in the form of ax^by^c, where a = 3, b = -3/4, and c = -3/2. Therefore, the product of a, b, and c is:

a * b * c = 3 * (-3/4) * (-3/2) = 27/8.

Hence, the product of a, b, and c is 27/8.

A function modeling the volume of the box can be found, and the values of x for which the volume is greater than 230 in2 are x = [-2.636, 2.636]. The largest volume is 480 in2, which is achieved when x = 5.

A function that models the volume V of the box can be found by subtracting four [tex]x2[/tex]from both the length and the width, and then multiplying the result to get the volume:

V = [tex](12 - 4x2)(20 - 4x2)[/tex]

To find the values of x for which the volume is greater than 230 in2, we can solve the equation

V = [tex](12 - 4x2)(20 - 4x2) = 230[/tex] for x.

This gives x values of ±2.636

Thus, the values of x for which the volume is greater than 230 in2 are x = [[tex]-2.636, 2.636[/tex]].

The largest volume that such a box can have is 480 in2, which is obtained when x is equal to the length or width divided by two. This occurs when x = 10/2 = 5. Thus, the largest volume that such a box can have is 480 in2.

Let's assume that he starts with $0 in the account and makes a monthly contribution of $100 for 40 years, which is equal to 40 x 12 = 480 months.

The total contributions would be $100 x 480 = $48,000.

The interest earned on the account balance can be calculated as follows:

Interest = Account balance * Interest rate

At the end of each year, the interest is added to the account balance. So, after 40 years, the balance would be:

Year 1: $48,000 * 1.5% = $720

Balance = $48,000 + $720 = $48,720

Year 2: $48,720 * 1.5% = $730.80

rectangular Persian rug's measurements are 10 ft in length and 1 ft in width.

Let's say that the Persian rug is rectangular, with length "l" and width "w".

The total of a rectangle's four sides is known as the perimeter, and it can be calculated as follows:

Perimeter = 2l + 2w

Given that the distance around it is 22 feet, we can write:

2l + 2w = 22

When we simplify this equation, we obtain:

l + w = 11

A rectangle's area is determined by the product of its length and breadth, which may be written as follows:

l x w = area

Given that the space is 10 square feet, we can write:

l x w = 10

Two equations with two variables are now available:

L+W = 11, and L x W = 10.

To find l and w, we can utilise substitution or elimination. For instance, we can solve for w from the first equation in terms of l:

w = 11 - l

Using this expression as w's replacement in the second equation, we obtain:

l x (11 - l) = 10

The result of expanding and rearrangement is a quadratic equation:

l² - 11l + 10 = 0

Using the quadratic formula or factoring, we can solve this quadratic problem. Factoring results in:

(l - 10)(l - 1) = 0

so either l = 10 or l = 1 is true.

w = 1 if l = 10, otherwise. w equals 10 if l = 1.

As w is always smaller than l, we have

Answer:

Step-by-step explanation:

In a parallelogram, opposite sides are congruent. To prove this, you would need to show that the following two conditions are true:

The length of one pair of opposite sides is equal.

The two pairs of opposite sides are parallel.

To show these two conditions, you may need additional segments or points such as:

Perpendicular lines or segments to the sides to help show the sides are parallel.

Diagonal segments to help show that the parallelogram is a rectangle and that the sides are equal in length.

By showing these two conditions, you can conclude that the opposite sides of a parallelogram are congruent.

To compare the amount of money that Patrick and Brooklyn would have after 2 years, we need to calculate the interest earned using each of their methods.

For Patrick, who deposited $300 with an interest rate of 3% compounded quarterly, the formula to calculate the amount after 2 years (8 quarters) is:

A = P(1 + r/n)^(nt)

Where:

P = principal amount ($300)

r = interest rate (3%)

n = number of times compounded per year (4)

t = time in years (2)

Substituting the values into the formula:

A = $300(1 + 0.03/4)^(4 * 2)

A = $300(1.0075)^8

A = $300 * 1.06173

A = $318.52

For Brooklyn, who deposited $300 with an interest rate of 5% compounded monthly, the formula to calculate the amount after 2 years (24 months) is:

A = P(1 + r/n)^(nt)

Where:

P = principal amount ($300)

r = interest rate (5%)

n = number of times compounded per year (12)

t = time in years (2)

Substituting the values into the formula:

A = $300(1 + 0.05/12)^(12 * 2)

A = $300(1.00417)^24

A = $300 * 1.09722

A = $328.17

Therefore, after 2 years, Brooklyn would have $328.17, which is more money than Patrick's $318.52.

Answer:

100π - 192 or 122.159....

Step-by-step explanation:

In order to find the diameter we much first split the rectangle diagonally and find the hypotenuse using Pythagorean theorem.

a^2 + b^2 = c^2

16^2 + 12^2 = c^2

400 = c^2

c = 20

If the diameter of the rectangle is 20, the radius is just half of that which is 10. Then you just need to a do a basic calculation for area of a circle and then subtract out the area of the rectangle.

Area of circle = πr^2 = π(10^2) = 100π (keeping it in exact value since π is infinite)

Area of rectangle = lw = (16)(12) = 192

Area of shaded area = 100π - 192 (exact) = 122.159 (estimate)

The slope of a line parallel to another line will have the same slope as the original line. To find the slope of the line 25x - 5y = -10, we need to rearrange the equation into the slope-intercept form y = mx + b, where m is the slope.

First, we'll isolate y:

25x - 5y = -10

5y = 25x + 10

y = (25/5)x + 2

So the slope of the line 25x - 5y = -10 is m = 25/5 = 5.

Therefore, a line parallel to 25x - 5y = -10 will have a slope of m = 5.
