Answer:

  $12

Step-by-step explanation:

You want to know the amount that has a tax of $0.72 when the tax rate is 6%.

The tax is computed by multiplying the price by the tax rate.

  tax = price × (tax rate)

  $0.72 = price × 0.06

  price = $0.72/0.06 = $(72/6) = $12

The original price of the bracelet is $12.

To the total of 99 cookies, there are 27 cookies in middle pile.

Let's call the number of cookies in the first pile "x". Then, the number of cookies in the second pile is 1/2 of x, or (1/2)x, and the number of cookies in the third pile is 1/3 of x, or (1/3)x.

We know that the total number of cookies is 99, so we can write an equation:

x + (1/2)x + (1/3)x = 99

To solve for x, we can first find a common denominator:

(6/6)x + (3/6)x + (2/6)x = 99

(11/6)x = 99

x = (6/11) * 99

x = 54

So, there are 54 cookies in the first pile, (1/2)x = (1/2)*54 = 27 cookies in the second pile, and (1/3)x = (1/3)*54 = 18 cookies in the third pile. In the middle pile there are 27 cookies.

Para resolver este problema, primero tenemos que multiplicar las fracciones:

3/5 x 4/7 = 12/35

Luego, encontramos cuántas docenas son 12/35 de 420 docenas:

(12/35) x 420 = 144

Así que 3/5 de 4/7 de 420 docenas (que es equivalente a 12/35 de 420 docenas) representa 144 docenas de huevos.

Para encontrar el número total de huevos, multiplicamos 144 docenas por 12 huevos por docena:

144 x 12 = 1,728

Por lo tanto, 3/5 de 4/7 de 420 docenas representa 1,728 huevos.

The probability of the first three cards being 3 aces and the last one being a king is 1/66,300.

The probability of drawing an ace from a deck of 52 cards is 4/52 (since there are 4 aces in the deck), and the probability of drawing a king is 4/52 as well.

Since the cards are dealt with no replacement, the probability of drawing three aces in a row is

(4/52) × (3/51) × (2/50) = 1/5525

This is because after each card is drawn, there is one less ace in the deck, and one less card overall.

Now, we need to multiply this probability by the probability of drawing a king as the fourth card. Since there are only 48 cards left in the deck at this point (since three cards have already been drawn), the probability of drawing a king is

4/48 = 1/12

Therefore, the probability of drawing 3 aces and 1 king in a row is

(1/5525) × (1/12) = 1/66300

Answer:

We cannot determine the exact number of votes for Tim or Selena without additional information. However, we can determine the fraction of the whole class that voted for each candidate based on the given information.

If only one third of the students cast votes, that means that two thirds did not vote. Therefore, the fraction of the whole class that voted for Tim and Selena is each equal to one third of the total number of students.

To calculate these fractions, we can use the following formula:

Fraction of class = Number of students who voted / Total number of students

Let's assume that there are N students in the class. Then, the number of students who voted for Tim is (1/3)N, and the number of students who voted for Selena is also (1/3)N.

So, the fraction of the whole class that voted for Tim is:

(1/3)N / N = 1/3

Similarly, the fraction of the whole class that voted for Selena is also 1/3.

Since we don't know the exact number of votes for each candidate, we cannot determine who received more votes.

The average rate of change from year 1 to year 10 is: (150 - 69)/9 = 9 based on the given function.

The amount of maize the farmer's land is yielding in pounds per acre over x years is represented by the function f(x)=[tex]-x^2+20x+50[/tex].

We must compute the change in f(x) for the range [1,10] and divide by the interval's length to determine the average rate of change from year 1 to year 10.

f(1) = [tex]-(1)^2[/tex] + 20(1) + 50 = 69

f(10) = [tex]-(10)^2[/tex] + 20(10) + 50 = 150

Hence, the change in f(x) throughout the range [1,10] is as follows:

f(10) - f(1) = 150 - 69 = 81

And the interval [1,10] has the following length:

10 - 1 = 9

Thus, from year one to year ten, the average rate of change is:

(150 - 69)/9 = 9

By interpreting the average rate of change, we can conclude that from year 1 to year 10, the farmer's land's yield of maize per acre is growing at a pace of 9 pounds each year. This indicates that, on average, throughout the course of these ten years, the farmer can anticipate harvesting 9 extra pounds of maize per acre.

Based on my knowledge, I would expect a negative correlation between the amount of gas in a car's gas tank and the total distance the car has traveled since last being filled with gas.

As the car travels, the amount of gas in the tank decreases. Thus, if the car has traveled a long distance since being filled up, it is likely that there is less gas in the tank. Therefore, there should be a negative correlation between the amount of gas in the tank and the distance traveled, meaning that as the distance traveled increases, the amount of gas in the tank decreases.

A scatter plot of these two variables should show a downward-sloping trend, indicating the negative correlation.

The cost of 4 kilograms is $13 if the unit rate is $3.25kg.

What is the unit rat?

The unit rate is a rate in which the second term in the ratio is 1. For example, if you have a rate of 60 miles per hour, the unit rate would be 60 miles per 1 hour, or simply 60 miles per hour. Another example is if you have a unit price of $2.50 per pound of apples, the unit rate would be $2.50 per 1 pound, or simply $2.50 per pound.

If the unit rate is $3.25/kg, then the cost of 1 kg is $3.25. To find the cost of 4 kg, we can multiply the cost of 1 kg by 4:

4 kg x $3.25/kg = $13

The rate at which the height of the water is increasing when water is being pumped in at a rate of 2/3 m/s and the water is 9m deep is 0.667 m/s.

We can start by using the formula for the volume of a square pyramid to find the volume of water in the tank. Let V be the volume of water in the tank and h be the height of the water.

V = (s² [h])/3

We know that the base of the pyramid is 3m by 3m, so s = 3. Also, the height of the pyramid is 16m, so we have:

V = (3² [h])/3

V = 3h

Now, we can find the rate of change of the volume with respect to time:

dV/dt = 3 [dh/dt]

We know that water is being pumped in at a rate of 2/3 m/s, so dh/dt = 2/3. We want to find how fast the height increases when the water is 9m deep, so h = 9. Substituting these values, we get:

dV/dt = 3 [dh/dt]

dV/dt = 3 [2/3]

dV/dt = 2

Therefore, the rate at which the volume of water is increasing is 2 cubic meters per second. To find the rate at which the height of the water is increasing, we need to solve for dh/dt:

dV/dt = 3 [dh/dt]

2 = 3 * dh/dt

dh/dt = 2/3

So the height of the water is increasing at a rate of 2/3 m/s when the water is 9m deep. Rounded to 3 decimal places, the answer is 0.667 m/s.

what is equation ?

An equation is a mathematical statement that asserts that two expressions are equal. In other words, an equation says that one expression on the left side of the equals sign is the same as the expression on the right side of the equals sign. An equation typically includes variables

In the given question,

To determine the equation of the line passing through the points (0,-3) and (2,0), we can use the slope-intercept form of a linear equation:

y = mx + b

where m is the slope and b is the y-intercept.

The slope of the line can be found using the formula:

m = (y₂ - y₁) / (x₂ - x₁)

where (x₁, y₁) = (0,-3) and (x₂, y₂) = (2,0)

m = (0 - (-3)) / (2 - 0) = 3/2

So the equation of the line is:

y = (3/2)x - 3

Now we can check which ordered pair is a solution to this equation by plugging in the x and y values into the equation and seeing if it holds true.

A. (0,-3)

y = (3/2)x - 3

-3 = (3/2)(0) - 3

-3 = -3

This is true, so (0,-3) is a solution.

B. (2,0)

y = (3/2)x - 3

0 = (3/2)(2) - 3

0 = 0

This is true, so (2,0) is a solution.

C. (2,2)

y = (3/2)x - 3

2 = (3/2)(2) - 3

2 = 0

This is false, so (2,2) is not a solution.

D. (-3,0)

y = (3/2)x - 3

0 = (3/2)(-3) - 3

0 = -9/2

This is false, so (-3,0) is not a solution.

Therefore, the solutions to the equation represented by the graph are A. (0,-3) and B. (2,0).

Step-by-step explanation:

The total amount of water supplied per hour inside a circle of radius 14 is approximately79.90 ft^3 per hour, and the total amount of water that goes through the sprinkler per hour is approximately  2π ft^3 per hour. As R approaches infinity, the total amount of water supplied per hour approaches  2 ft^3 per hour.

To find the total amount of water supplied per hour inside of a circle of radius 14, we need to integrate the function e^(-r) over the region of the circle total amount of water = ∫∫ e^(-r) dA

where the integration is over the circular region of radius 14, and dA is the differential area element.

Using polar coordinates, we can write dA = r dr dθ, and the limits of integration are 0 ≤ r ≤ 14 and 0 ≤ θ ≤ 2π. Substituting these values, we get:

total amount of water = ∫(0 to 2π) ∫(0 to 14) e^(-r) r dr dθ

Integrating with respect to r first, we get:

total amount of water = ∫(0 to 2π) [-e^(-r)](0 to 14) dθ

total amount of water = ∫(0 to 2π) (1 - e^(-14)) dθ

total amount of water = (1 - e^(-14)) ∫(0 to 2π) dθ

total amount of water = 2π(1 - e^(-14))

Thus, the total amount of water supplied per hour inside of a circle of radius 14 is approximately 79.90 ft^3 per hour.

To find the total amount of water that goes through the sprinkler per hour, we need to integrate the function e^(-r) over the entire plane:

total amount of water = ∫∫ e^(-r) dA

where the integration is over the entire plane, and dA is the differential area element.

Using polar coordinates, we can write dA = r dr dθ, and the limits of integration are 0 ≤ r ≤ ∞ and 0 ≤ θ ≤ 2π. Substituting these values, we get:

total amount of water = ∫(0 to 2π) ∫(0 to ∞) e^(-r) r dr dθ

Integrating with respect to r first, we get:

total amount of water = ∫(0 to 2π) [-e^(-r)](0 to ∞) dθ

total amount of water = ∫(0 to 2π) (1) dθ

total amount of water = 2π

Thus, the total amount of water that goes through the sprinkler per hour is exactly 2π ft^3 per hour.

To calculate the total amount of water supplied per hour inside a circle of radius R, then let R → ∞, we can use the result from part B and multiply it by the ratio of the areas of the two circles:

total amount of water = (total amount of water inside circle of radius R) × (area of circle of radius R)/(area of entire plane)

total amount of water = (2πR^2(1-e^(-R))) / (πR^2)

total amount of water = 2(1-e^(-R))

Now we can let R → ∞:

total amount of water = 2

Thus, the total amount of water supplied per hour inside a circle of infinite radius is exactly 2 ft^3 per hour.

The value of T(v), express v as linear combination in the basis B and the matrix representation of T obtain is T(v) = [4, -4].

To find T(v), we need to express v as a linear combination of the basis vectors of R^3 with respect to B:

v = (-1)[0] + (-1)[0] + (1)[1]

This means that the coordinate vector of v with respect to B is [-1, -1, 1].

To find the matrix representation of T with respect to the standard bases of R^3 and R^2, we can apply T to each of the basis vectors:

T([1, 0, 0]) = [1, 3]

T([0, 1, 0]) = [-1, 1]

T([0, 0, 1]) = [2, -2]

We can arrange the results in a matrix:

[1 -1 2]

[3 1 -2]

The matrix [1 -1 2; 3 1 -2] represents T with respect to the standard bases of R^3 and R^2.

To find T(v), we can multiply the matrix representation of T with the coordinate vector of v with respect to B:

T(v) = [1 -1 2; 3 1 -2] * [-1; -1; 1] = [4; -4]
