If the car's wheels revolve 10,000 times without slipping, the car will travel approximately 9.92 miles.

The circumference of a circle (which is the distance around it) is given by the formula:

C = πd, where d is the diameter of the circle.

In this case, the diameter of the car's wheels is 20 in., so the circumference of each wheel is:

C = πd

C= π(20 in.) =

C = 20π in.

If the car's wheels revolve 10,000 times without slipping, then the total distance the car travels is:

distance = number of revolutions × circumference

distance = 10,000 × (20π in.)

To convert this distance to miles, we need to divide by the number of inches in a mile, which is 63,360 in.

distance = (10,000 × 20π in.) / 63,360 in./mi

distance = 9.92 miles

Therefore, distance traveled by the car is 9.92 miles.

No, she have not enough time to fill the pool before he gets home. The garden hose with flow rate 24 gal/min will take 40 minutes to complete fill up the tank that is t ~ 40 minutes. So, she cannot complete fill up the pool before he come.

We have, the time in which Ines's younger brother will be home = an half hour = 1/2 hour

water flow rate of garden's hose = 24 gal/min

She want to fill up the pool. From the figure, depth of pool = 3 ft

Width of pool = 10 in.

1 inch = 0.0833 feet

So, 10 inches = 0.833 feet

outer diameter of pool = 9 ft

so, outer radius of pool = 4.5 ft

Now, inner diameter of pool/tank = outer diameter - 2(width)

= 9 - 2×0.833

= 9 - 1.666 = 7.334

Inner radius of pool = 7.334/2 = 3.667 ft

Water flow rate, Q = 24 gal/min

= 24/7.48 gal ( since 1 ft³ = 7.48 gal)

= 3.20 ft³

Using formula, Q = volume/ time

where t --> time to fill up the pool through hose

Volume of tank/pool = surface area × height (depth)

= π r² × h , where r is inner radius

= π (3.667)² × 3 ft³

= 126.71 ft³

So, Q = 126.71 ft³/t

=> t = 126.71 ft³/3.20 ft³

The Saints had the best overall record for the season because they had a larger mean value of about 200 points, whereas the Saints had a larger median value of 12 points.

To determine which team had the best overall record for the season, we need to consider the total number of points earned by each team across all games. We can calculate the total points for each team by adding up the points earned in each game.

For the Saints:

Total points = 21+12+3+3+10+10+14+3+12+28+40+10+17+20+7 = 200

For the Cowboys:

Total points = 10+3+8+6+24+12+21+3+10+28+28+7+7+13+3 = 183

Therefore, the Saints earned a total of 200 points, while the Cowboys earned a total of 183 points. Therefore, the Saints had the better overall record for the season.

To compare the central tendency of the points earned by each team, we can use either the mean or the median. However, in this case, the median is a better measure of center because it is less sensitive to extreme values than the mean.

Calculating the median for each team:

For the Saints:

Arrange the points earned in ascending order: 3 3 7 10 10 12 12 14 17 20 21 28 40

The median value is the middle value, which is 12.

For the Cowboys:

Arrange the points earned in ascending order: 3 3 6 7 8 10 10 12 13 21 24 28

The median value is the middle value, which is 10.

Therefore, the Cowboys have a median value of 10 points, while the Saints have a median value of 12 points. However, as we already determined, the Saints had a better overall record for the season based on the total points earned.

The dimensions of the can that use the least amount of material are a radius of approximately 4.38 cm and a height of approximately 3.11 cm.

To design a can that uses the least amount of material, we want to minimize its surface area. Since the can is shaped like a right circular cylinder, its surface area is given by:

A = 2πr² + 2πrh

where r is the radius of the base of the cylinder and h is its height.

We also know that the volume of the can is given by:

V = πr²h

We can use these equations to express h in terms of r, and then substitute this expression for h into the equation for surface area. Then we can differentiate the resulting equation with respect to r, set it equal to zero, and solve for r to find the value of r that minimizes surface area.

First, we solve for h in terms of r by rearranging the equation for volume:

h = V/(πr²)

Substituting this expression for h into the equation for surface area, we get:

A = 2πr² + 2πr(V/(πr²))

A = 2πr² + 2V/r

To minimize A, we differentiate with respect to r:

dA/dr = 4πr - 2V/r²

Setting this expression equal to zero and solving for r, we get:

4πr = 2V/r²

r³ = V/(2π)

Substituting the given value for V, we get:

r³ = 432/2π

r ≈ 4.38 cm

Now we can use the expression for h in terms of r to find the corresponding height:

h = V/(πr²) ≈ 3.11 cm

Therefore, the dimensions of the can that use the least amount of material are a radius of approximately 4.38 cm and a height of approximately 3.11 cm.

A percentage is a ratio or number expressed as a percentage of 100 in mathematics. The abbreviations "pct.," "pct," and "pc" are also used on occasion. Despite this, the percentage symbol "%" is commonly used to represent it. The % value is dimensionally empty. In essence, percentages are fractions with a denominator of 100. To indicate that a number is a percentage, a percent sign (%) should be placed next to it. For example, you receive a 75% on an exam if you correctly respond to 75 out of 25 pages (75/100). Divide the result by 100 after dividing the amount by the total when calculating percentages. The percentage is found by multiplying (value/total) by 100%.

Find: A - ? (area)

Let's start by writing down both circumference and area formulas:

[tex]c = 2\pi \times r[/tex]

[tex]a = \pi \times {r}^{2} [/tex]

We can find the radius (r) from the 1st formula:

[tex]r = \frac{c}{2\pi} = \frac{14.4}{2\pi} =14 \frac{4}{10} \times \frac{1}{2\pi} = \frac{144}{10} \times \frac{1}{2\pi} = \frac{144}{20\pi} = \frac{36}{5\pi} [/tex]

The required transformed coordinates of the quadrilateral as:A'(-10, 0),B'(-8, -6),C'(-3, -7), D'(0, -3).

The image matrix for the composite transformation of a rotation of 270º and a reflection over the line y=-x can be found by multiplying the transformation matrices for each operation.

The rotation matrix for 270º counterclockwise can be represented as:

[tex]$R_{270} = \begin{bmatrix}0 & -1 \1 & 0\end{bmatrix}$[/tex]

The reflection over the line y=-x can be represented as:

[tex]$F_{y=-x} = \begin{bmatrix}0 & -1 \-1 & 0\end{bmatrix}$[/tex]

To find the composite transformation matrix, we multiply the two matrices:

[tex]$M = F_{y=-x} \cdot R_{270} = \begin{bmatrix}0 & -1 \-1 & 0\end{bmatrix} \cdot \begin{bmatrix}0 & -1 \1 & 0\end{bmatrix} = \begin{bmatrix}1 & 0 \0 & -1\end{bmatrix}$[/tex]

To apply this transformation to the coordinates of the quadrilateral ABCD, we write each point as a column vector:

[tex]$A = \begin{bmatrix}-10 \0\end{bmatrix}$[/tex],

[tex]$B = \begin{bmatrix}-8 \6\end{bmatrix}$[/tex],

[tex]$C = \begin{bmatrix}-3 \7\end{bmatrix}$[/tex],

and

[tex]$D = \begin{bmatrix}0 \3\end{bmatrix}$[/tex]

We can then apply the composite transformation matrix M to each of these vectors:

[tex]$A' = M \cdot A = \begin{bmatrix}1 & 0 \0 & -1\end{bmatrix} \cdot \begin{bmatrix}-10 \0\end{bmatrix} = \begin{bmatrix}-10 \0\end{bmatrix}$[/tex]

[tex]$B' = M \cdot B = \begin{bmatrix}1 & 0 \0 & -1\end{bmatrix} \cdot \begin{bmatrix}-8 \6\end{bmatrix} = \begin{bmatrix}-8 \-6\end{bmatrix}$[/tex]

[tex]$C' = M \cdot C = \begin{bmatrix}1 & 0 \0 & -1\end{bmatrix} \cdot \begin{bmatrix}-3 \7\end{bmatrix} = \begin{bmatrix}-3 \-7\end{bmatrix}$[/tex]

[tex]$D' = M \cdot D = \begin{bmatrix}1 & 0 \0 & -1\end{bmatrix} \cdot \begin{bmatrix}0 \3\end{bmatrix} = \begin{bmatrix}0 \-3\end{bmatrix}$[/tex]

We can then write the transformed coordinates of the quadrilateral as:

A'(-10, 0),

B'(-8, -6),

C'(-3, -7),

D'(0, -3)

Answer:

i) ABCDEF has an area of 98m

ii) Flower bed has an area of 6m

iii) The area of the grass is 92m

Hope this helps!

Step-by-step explanation:

The area of a triangle is  [tex]\frac{1}{2}[/tex] × L × H

The area for the triangle flower bed will be [tex]\frac{1}{2}[/tex] × 6m × 2m or 6m.

In order to find the entire area of ABCDEF, draw a segment FC to create a trapezoid and a rectangle. The rectangle has an area of 77m ( 7 × 11 ). The trapezoid has a formula of [tex]\frac{1}{2}[/tex] × ( b + b ) × h, this would be [tex]\frac{1}{2}[/tex] × ( 10 + 11 ) × 2.

The trapezoid has an area of 21, this added to the rectangle's area of 77 equals 98m as the total area of the garden.

Subtract the area of the flower bed ( 6 ) from the area of the garden, and you get an area of 92m. This is the area of grass.

This inequality states that the total cost of buying x gumballs and y jawbreakers must be less than or equal to $3.00.

Let x be the number of gumballs that Bob buys, and let y be the number of jawbreakers that Bob buys.

The cost of buying x gumballs is $0.50 times x, or 0.50x. The cost of buying y jawbreakers is $0.30 times y, or 0.30y.

Bob has $3.00 to spend on candy, so we can write an inequality to represent the total cost of buying both types of candy:

0.50x + 0.30y ≤ 3.00

This inequality states that the total cost of buying x gumballs and y jawbreakers must be less than or equal to $3.00.
