There are 24 different winning scenarios possible in the family money game, calculated using permutations since the person in charge of choosing cannot win and there are three distinct prizes to be distributed among four participants.

Explanation:

The family money game presents a probability problem where one must calculate the number of different winning scenarios. Since there are five people including you, and you cannot win because you are the one choosing, you only need to consider the remaining four participants. Each person can win one of the three prizes - $1, $5 or $10 - since you won the $50 prize last time and you are exempt from winning again.

We need to look at the number of ways to arrange three distinct prizes among four people. This can be calculated using permutations where the order of assignment is important.

The formula for permutations is given as P(n, k) = n! / (n-k)!, where n is the total number, and k is the number to choose. In this case, n=4 (people) and k=3 (prizes). Hence, the calculation for permutations would be P(4, 3) = 4! / (4-3)! = (4 x 3 x 2 x 1) / 1 = 24.

Therefore, there are 24 different winning scenarios possible in this play of the money game.

The green area in the figure above represents a section of grass for a putting green. Find the area of the sector of grass.

A. A= 32π ft²

B. A= 6π ft²

C. A= 36π ft²

D. A= 72π ft²

Answer:

C. A= 36π ft²

Step-by-step explanation:

The image below is where your question emanated. The area of the sector of grass can be calculated below.

Area of a sector = ∅/360 × πr²

where

∅ = angle from the center of the circle

r = radius

Area of a sector = ∅/360 × πr²

r = 12 ft

∅ = 90°

Area of a sector = 90/360 × π × 12²

Area of a sector = 90/360 × π × 144

Area of a sector = 1/4 × 144π

Area of a sector = 144π/4

Area of a sector = 36π ft²

Answer:

8 dollars

Step-by-step explanation:

The required selling price of an item that has originally price $80 is $27.89.

Given that,
Each Saturday, a store reduces the price of any unsold item by 10%.
An item was priced at $80, on Saturday of the first week it is marked down to $72.
At the end of the second week, it drops to $64.80, and at the end of the third week, the price is decreases to $58.32.  
This continues for 10 weeks.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
From the given,
The relation is given as,
Selling price = original price [1 - 0.10]ˣ
Substitute the value in the above equation,
selling price = 80 [0.9]¹⁰
The selling price = $27.89

Thus, the required selling price of an item that has an original price $80 is $27.89.

Answer:

yes that the right answer

=====================================================

Work Shown:

E = exterior angle

n = number of sides

For any regular polygon, E = 360/n.

In this case, n = 10 as there are 10 sides, so E = 360/n = 360/10 = 36 degrees is the measure of each exterior angle.

Each interior angle is 180-E = 180-36 = 144 degrees

--------------

An alternative is to plug n = 10 into the formula below to get the measure of each interior angle i

i = 180(n-2)/n

i = 180(10-2)/10

i = 180(8)/10

i = 1440/10

i = 144

note: S = 180(n-2) is the sum of all the interior angles of any convex polygon. Dividing this sum over n will evenly divide the angle total to each interior angle.

Answer:

-4x + 5

Step-by-step explanation:

to be parallel, you need the same slope,

so it has to be -4x

and to go through the point (1,1) the y intercept has to be 5

because if you are using that slope, going down four and over one starting at (0,5) will connect the line to (1,1)

If it helps to draw it out or somehow visually see it, that would be a great idea

but in sum, the only answer is  y = -4x + 5

(i didn't see someone had already answered)

(but the answer above uses the slope of 2x and I am unsure why because it says -4x on your question)

Answer:

25.133

Step-by-step explanation:

area is pi*r^2. divide area by 3.14 and then sqrt to find radius. 6.28*radius= circumference, so 6.28*4=25.133

Answer:

25.12

Step-by-step explanation:

The total surface area to be painted in the hotel room is 644 square feet.

To calculate the surface area of the walls and the ceiling to be painted in a room, we separate the two calculations since the walls and the ceiling have separate dimensions. The floor of the room is a 14-foot square, which means that each side of the wall is 14 feet long. The ceiling also has the same dimensions as the floor. The room has a height of 8 feet.

The area of the ceiling is equal to the area of the floor since they are both squares with the same side length, which is calculated as follows:

Area of ceiling = Side length × Side length

Area of ceiling = 14 feet × 14 feet = 196 square feet

Next, we calculate the surface area of the walls. There are four walls in the room, and each wall has the same height of 8 feet. The wall area is calculated as follows:

Area of one wall = Side length × Height

Area of one wall = 14 feet × 8 feet = 112 square feet

Since there are four walls, total wall area = 4 × 112 square feet = 448 square feet

Finally, we add the area of the ceiling to the total wall area to get the total surface area to be painted:

Total surface area = Ceiling area + Wall area

Total surface area = 196 square feet + 448 square feet = 644 square feet

Therefore, the total surface area of the walls and ceiling of the room that will be painted is 644 square feet, ignoring any doors or windows.

Step 5 is to ( C ) take the Square root of both sides

The radius of the cone is ( A ) 2 inches

The radius of the cone is 2 inches.

The volume of a cone is determined by the amount of space occupied by the cone. A three-dimensional figure having a single circular base is known as a cone. The base and the vertex are connected by a curved surface. A cone with a radius of r has a volume V that is one-third the area of the base B times the height h.

[tex]V=\frac{1}{3} \pi r^{2} h[/tex] or [tex]V=\frac{1}{3} Bh[/tex],

Since, [tex]B=\pi r^{2}[/tex]

Given that the volume of cone V is 48π cubic inches and Height of the cone h=36 inches.Volume of cone [tex]V=\frac{1}{3} \pi r^{2} h[/tex] -------1

Here, the base of the cone is circular in shape and the area of circle is [tex]\pi r^{2}[/tex]. Consider [tex]B=\pi r^{2}[/tex]

Substituting the area of base in the equation (1).

[tex]V=\frac{1}{3} \pi r^{2}[/tex]

    [tex]= \frac{1}{3} Bh[/tex]

Substitute the given values in the equation (1).

⇒ [tex]48\pi =\frac{1}{3} \pi r^{2} 36[/tex]

⇒ [tex]\frac{48\pi }{36\pi } =\frac{r^{2} }{3}[/tex]

⇒ [tex]\frac{12(3)}{9}=r^{2}[/tex]

⇒[tex]4=r^{2}[/tex]

Answer:

B) $90

Step-by-step explanation:

To work out the value of the computer after 8 years you would first have to convert the percentage into a decimal. To achieve this you would divide the percentage of 25 by 100, which gives you 0.25. This is because percentages are out of 100. The next step is to minus 0.25 from 1, which gives you 0.75. This is because the value of the computer is diminishing. Then you would multiply 900 by 0.75 to the power of 8, which gives you 90. You would multiply to the power of 8 as the percentage decrease will need to take place 8 times due to it being annual.

1) Divide 25 by 100.

[tex]25/100=0.25[/tex]

2) Minus 0.25 from 1.

[tex]1-0.25=0.75[/tex]

3) Multiply 900 by 0.75 by the power of 8.

[tex]900*0.75^{8} =90.1[/tex]

4) Round to the nearest whole number.

90

Final answer:

Using the exponential decay formula, the value of Dan's computer after 8 years, with a 25% annual decline, is approximately $90, corresponding to option B.

Explanation:

The question asks about the depreciation of the value of a computer over time. To calculate the approximate value of Dan's computer after 8 years, with a 25% annual decrease in value, we can use the formula for exponential decay - V = P(1 - r)^t, where V is the final value, P is the initial value, r is the rate of decay, and t is the time in years.

The annual rate of decay, r, is 25% or 0.25.

The time in years, t, is 8 years.

Substituting these values into the formula gives us:

V = 900 (1 - 0.25)^8 = 900 (0.75)^8 = 900 * 0.10011291504 ≈ $90.10

After rounding, Dan can expect the approximate value of the computer to be about $90 after 8 years, which corresponds to option B.

The rate of appreciation of the ring is approximately 6.52% per year.

How to find the rate of appreciation

We shall use the formula for simple interest to find the rate of appreciation:

Rate of appreciation = (Final value - Initial value / Initial value * Number of years) * 100

Given:

Final value = $1875

Initial value = $750

Number of years = 2024 - 2001 = 23 years

Let us plug the values into the formula:

Rate of appreciation = ($1875 - $750 / $750 * 23) *100

Rate of appreciation = $1,125/1,7250 * 100

Rate of appreciation ≈ 0.0652 * 100

Rate of appreciation ≈ 6.52%

Hence, the rate of appreciation of the ring is ≈ 6.52% per year.

The rate of appreciation is 150%.

To find the rate of appreciation, we'll use the formula for simple interest:

[tex]\[ \text{Simple Interest} = \frac{{\text{Final Value} - \text{Initial Value}}}{{\text{Initial Value}}}\times 100 \][/tex]

Given:

Initial value (purchase price) = $750

Final value (appraised price) = $1875

Substitute these values into the formula:

[tex]\[ \text{Simple Interest} = \frac{{1875 - 750}}{{750}} \times 100 \][/tex]

[tex]\[ = \frac{{1125}}{{750}} \times 100 \][/tex]

[tex]\[ = 1.5 \times 100 \][/tex]

[tex]\[ = 150\% \][/tex]

So, the rate of appreciation is 150%.
