a. The area of the family room is 162 ft².

b. 24 tiles will be needed to cover the floor.

c. Mr. Dieter will have to buy 2 boxes to tile the family room.

The solution has been obtained by using the arithmetic operations.

What are arithmetic operations?

All real numbers are thought to be sufficiently described by the four basic operations, also referred to as "arithmetic operations." The mathematical operations quotient, product, sum, and difference come after division, multiplication, addition, and subtraction.

a. There are two different shapes of which one is rectangle and other is triangle.

So,

⇒ Area of rectangle = length x width

⇒ Area of rectangle = 16 x 8

⇒ Area of rectangle = 128 ft²

Also,

⇒ Area of first triangle = [tex]\frac{1}{2}[/tex] x base x height

⇒ Area of first triangle = [tex]\frac{1}{2}[/tex] x 4 x 3

⇒ Area of first triangle = 6 ft²

Similarly,

⇒ Area of first triangle = [tex]\frac{1}{2}[/tex] x base x height

⇒ Area of first triangle = [tex]\frac{1}{2}[/tex] x 8 x 7

⇒ Area of first triangle = 28 ft²

On adding the three areas, we get

⇒ Area of family room = 128 + 6 + 28

⇒ Area of family room = 162 ft²

b. We will convert the area into inches.

We know that 1 feet = 12 inches.

So, using the multiplication, we get

162 feet = 162 * 12 in²

162 feet = 1944 in²

Now,

⇒ Area of tile = 9 * 9

⇒ Area of tile = 81 in²

So,

⇒ Number of tiles = [tex]\frac{1944}{81}[/tex]

⇒ Number of tiles = 24

c. Since, tiles are sold in boxes of 12 so, using the division operation, we get

⇒ Number of boxes needed = [tex]\frac{24}{12}[/tex]

⇒ Number of boxes needed = 2

Hence, the required solution has been obtained.

The expression is undefined when x = 9. the expression will be undefined when x-9 = 0.

To find the values of x for which the expression is undefined, we need to look for values of x that would make the denominator of the expression equal to zero. In this case, the denominator is x-9. Therefore, the expression will be undefined when x-9 = 0. Solving for x, we get x = 9.

When x is equal to 9, the denominator becomes zero, which would make the expression undefined as dividing by zero is undefined in mathematics. For all other values of x, the expression is defined and can be evaluated.

We can verify this by substituting x = 9 in the expression and observing that it becomes (9² - 36)/(9-9), which is (81-36)/0, and division by zero is undefined.

21)  Parallel: y = 3/4 x - 2 3/4

Perpendicular: y = [tex]\frac{-4}{3 }[/tex] x + 7 [tex]\frac{2}{3}[/tex]

Step-by-step explanation:

20)

y = mx + b

y = __x + ___  We need to find the slope that the y-intercept. We are given the slope 3/4.  We will you the x and y values from the point (2,5) to find the y intercept. Use 5 for y and 2 for x

y = mx + b

5 = 2(3/4) + b

5 = 3/2 + b  Subtract 3/2 from both sides

5 - 3/2 = 3/2 -3/2 +b

[tex]\frac{10}{2}[/tex] - [tex]\frac{3}{2}[/tex] = b

[tex]\frac{7}{2}[/tex] or 3 [tex]\frac{1}{2}[/tex]

y = 3/4x + 3 1/2

21)

Parallel slopes are equal so the slope will be 3/4.  Now we will use the x and y values from the point (5,1) to find the y-intercept.  We will use 1for y and 5 for x

y = mx + b

1 = 5(3/4) +b

1 = 15/4 + b  Subtract 15/4 from both sides.

[tex]\frac{4}{4}[/tex] - [tex]\frac{15}{4}[/tex] = [tex]\frac{15}{4}[/tex] - [tex]\frac{15}{4}[/tex] + b

[tex]\frac{-11}{4}[/tex] or - 2 [tex]\frac{3}{4}[/tex]

y = 3/4 x - 2 3/4

Perpendicular slopes or the opposite reciprocals.  So the slope of the reciprocal equations would be [tex]\frac{-4}{3}[/tex]. We would still use the x and y values from the point (5,1)

1 = -4/3(5) + b

1 = [tex]\frac{-20}{3}[/tex] + b  Add 20/3 to both sides

[tex]\frac{3}{3}[/tex] + [tex]\frac{20}{3}[/tex] = [tex]\frac{-20}{3}[/tex] + [tex]\frac{20}3}[/tex] + b

From the given question, the value of the height of the cone is given by 57.3 centimeters to the nearest 1 decimal place: Option B

We should note that a cone is a three-dimensional geometric figure with a flat and curved surface pointed towards the top.  It is formed by using a set of line segments or the lines which connects a common point, called the apex or vertex, to all the points of a circular base(which does not contain the apex)

The volume of the cone is given by the formula

Volume = 1/3πr²h

Where Volume = 1500 centimeters cube, radius = 5 cm, π = 22/7

1500 = 1/3*22/7*5*5*h

1500 = (22*5*5*h)/3*7

Simplifying the expression further we have

1500 = 550h/21

1500(21) = 550h

31500 = 550h

Making h the subject of the relation we have

h = 31500/550

h= 57.272727...

h= 57.3 to one decimal place

Answer:

Total amount = R41 337.50

Step-by-step explanation:

The value of the deposit is 15% of the total purchase price:

Deposit = 15/100 x R35 000

Deposit = R5 250

To calculate the balance that Claire will have to pay off, we need to subtract the deposit from the total purchase price:

Balance = Total purchase price - Deposit

Balance = R35 000 - R5 250

Balance = R29 750

To calculate the interest that Claire will have to pay on the balance, we can use the formula:

Interest = Principal x Rate x Time

where:

Principal is the amount of the balance

Rate is the annual interest rate (13%)

Time is the duration of the loan in years (3)

So, the interest that Claire will have to pay is:

Interest = R29 750 x 0.13 x 3

Interest = R11 587.50

Therefore, the total amount that Claire will have to pay back over the 3-year period is:

Total amount = Balance + Interest

Total amount = R29 750 + R11 587.50

Total amount = R41 337.50

Note that this assumes that the interest is calculated annually and added to the balance at the end of each year. In reality, the interest may be calculated differently depending on the terms of the hire purchase agreement.

P(x) is a continuous function on [0, 2]. We can conclude that the given function has a root on [0, 2].

The Intermediate Value Theorem is a mathematical theorem that states that a continuous function between two points takes on every value between the two points. The proof of this theorem is easy to understand and uses the definition of a continuous function. The theorem is used to establish the existence of roots or zeroes of functions.The statement is given by the Intermediate Value Theorem that “if f(x) is a continuous function on the interval [a,b], then for any value k that lies between f(a) and f(b) inclusive, there must be at least one value c on the interval [a,b] such that f(c)=k”.Use the Intermediate Value Theorem to show that P(x) = x5 + 4x3 − 10x − 6 has a root on [0, 2]Given, the function P(x) = x5 + 4x3 − 10x − 6Step 1: Verify if the function is continuous on [0, 2].The function P(x) is a polynomial function, and all the polynomial functions are continuous functions.

Therefore, P(x) is a continuous function on [0, 2].Step 2: Check the signs of the function at the endpoints f(0) and f(2).Let’s check f(0) and f(2)f(0) = P(0) = 0^5 + 4(0)^3 – 10(0) – 6= -6f(2) = P(2) = 2^5 + 4(2)^3 – 10(2) – 6= 50Step 3: Check if the value 0 lies between f(0) and f(2) inclusive.f(0) < 0 < f(2)Since 0 lies between f(0) and f(2), according to the Intermediate Value Theorem, there must be at least one value c on the interval [0,2] such that f(c)=0Hence, we can conclude that the given function has a root on [0, 2] Therefore, we can conclude that the given function has a root on [0, 2].
