The average age of all the customers in the store, given the percentages that are parents and not, is 39.2 years.

To answer this question, we will use a weighted average formula. Since the percentage of parents and non-parents is given, we can use these percentages as weights.

Weighted Average Age = (Weight for Parents x Average Age of Parents) + (Weight for Non-Parents x Average Age of Non-Parents)

Parents:

Percentage (weight) = 60% = 0.60

Average age = 52 years

Non-Parents:

Percentage (weight) = 40% = 0.40

Average age = 20 years

Weighted Average Age = (0.60 x 52) + (0.40 x 20)

Weighted Average Age = 39.2 years

The sales tax rate for the item is 3%.

To find the sales tax rate, we can divide the sales tax amount by the original cost of the item, and then multiply by 100 to express the result as a percentage.

Given:

Sales tax amount = $11.70

Original cost of item = $390

Sales tax rate = (Sales tax amount / Original cost of item) x 100

Plugging in the given values:

Sales tax rate = (11.70 / 390) x 100

Calculating:

Sales tax rate = 0.03 x 100

Final result:

Sales tax rate = 3%

So, the sales tax rate for the item is 3%.

Answer:

Step-by-step explanation:

To solve for f, we can cross-multiply the equation:

f/40 = 10/f

Multiplying both sides by 40f gives:

f^2 = 400

Taking the square root of both sides yields:

f = ±20

Therefore, the solutions for f are f = 20 and f = -20. However, since f represents a physical quantity (presumably a frequency), we take only the positive value:

f = 20

it would take Cody 40 bushels / 5.26 bushels per hour = 7.61 hours to pick 40 bushels of apples alone.

To begin, let's determine Lisa's individual work rate, or the amount of work she can complete in an hour.

The work formula states that the amount of work completed is equal to the product of the work rate and the amount of time spent working. Lisa's work rate is 40 bushels divided by 13 hours equals 3.08 bushels per hour.

Let C represent Cody's work rate, and let t represent the amount of time it takes him to pick 40 bushels on his own.

At the point when Lisa and Cody cooperate, they pick 40 bushels, so we can compose:

Lisa's work + Cody's work = Total work

3.08 bushels/hour * 4.8 hours + C * 4.8 hours = 40 bushels

14.78 + 4.8C = 40

4.8C = 25.22

C = 5.26 bushels per hour

Consequently, it would take Cody 40 bushels/5.26 bushels each hour = 7.61 hours to pick 40 bushels of apples alone.

Answer:

To find the greatest common factor (GCF) of 8a^3b^2 and 12ab^4, we need to factor each term into its prime factors and then find the common factors.

8a^3b^2 can be written as:

8a^3b^2 = 2^3 * 2 * a * a * a * b * b

12ab^4 can be written as:

12ab^4 = 2^2 * 3 * a * b * b * b * b

The common factors are 2, a, and b^2.

Therefore, the GCF of 8a^3b^2 and 12ab^4 is:

The probability of drawing a green block followed by a yellow block with replacement is 0.03, or 3%.

The probability of an event is calculated by dividing the total number of possible outcomes by the number of possible outcomes.

The likelihood of drawing a green block on the main draw is:

P(green) = (number of green blocks) / (total number of blocks)

P(green) = 4 / (4 + 6 + 7 + 3)

P(green) = 4 / 20

P(green) = 0.2

Since the blocks are replaced after each draw, the probability of drawing a yellow block on the second draw is still:

P(yellow) = (number of yellow blocks) / (total number of blocks)

P(yellow) = 3 / (4 + 6 + 7 + 3)

P(yellow) = 3 / 20

P(yellow) = 0.15

To find the probability of both events happening, we multiply the probabilities:

P(green, then yellow) = P(green) * P(yellow)

P(green, then yellow) = 0.2 * 0.15

P(green, then yellow) = 0.03

As a result, replacing a yellow block with a green one has a chance of 0.03, or 3%, being drawn.

The maximum FUTA deductions for the first quarter is $1092.Because none of the given options correspond to this result, the correct answer is not listed.

The Federal Unemployment Tax Act (FUTA) tax rate is 6% on the first $7,000 paid to each employee in a calendar year. Therefore, the maximum FUTA deduction for each employee is $420 ($7,000 x 0.06).

Person 1 earned $4700, so the FUTA deduction for Person 1 is $282 ($4700 x 0.06).

Person 2 earned $19,800, but only the first $7,000 is subject to FUTA. Therefore, the FUTA deduction for Person 2 is $420.

Person 3 earned $6500, so the FUTA deduction for Person 3 is $390 ($6500 x 0.06).

The total FUTA deduction for the first quarter is the sum of the FUTA deductions for each employee:

The depreciation schedule for this truck using the declining-balance method at twice the straight-line rate are $24,000, $33,600, $39.744, $43,502 and $45,248

To create the depreciation schedule, we'll start with the cost of the asset and subtract the depreciation for each year. The depreciation for each year is calculated by multiplying the declining-balance rate by the book value of the asset at the beginning of the year.

The book value is simply the cost of the asset minus the accumulated depreciation. So in year 1, the book value is $30,000, and the depreciation is $8,000 (the declining-balance rate) times $30,000, which is $24,000. This means that the accumulated depreciation at the end of year 1 is $24,000.

To calculate the book value at the end of year 1, we simply subtract the accumulated depreciation ($24,000) from the cost of the asset ($30,000), which gives us $6,000.

=> $30000 - $6000 = $24000

This process is continued for the next five years that can be illustrated through the table.

Part A: The maximum velocity occurs at t = 0. We can plug this value into the velocity function to find the maximum velocity:

v_max = 0² = 0

Part B: The time at which the vehicle comes to rest is T = 0.

What is function?

In mathematics, a function is a relationship between two sets of elements, called the domain and the range.

The first step is to integrate the acceleration function to obtain the velocity function. Then, we can integrate the velocity function to obtain the position function.

Let's assume that the acceleration function is given by:

a(t) = 2t, where t is time in seconds.

Part A:

To find the velocity function, we integrate the acceleration function with respect to time:

v(t) = ∫a(t)dt = ∫2tdt = t² + C

where C is the constant of integration. We can find C by using the initial condition v(0) = 0.

v(0) = C = 0

Therefore, the velocity function is given by:

v(t) = t²

To find the maximum velocity, we can take the derivative of the velocity function and set it equal to zero:

dv/dt = 2t = 0

t = 0

Therefore, the maximum velocity occurs at t = 0. We can plug this value into the velocity function to find the maximum velocity:

v_max = 0² = 0

So, the maximum velocity is 0 m/s.

Part B:

To find the position function, we integrate the velocity function with respect to time:

x(t) = ∫v(t)dt = ∫t²dt = (1/3)t³ + C

where C is the constant of integration. We can find C by using the initial condition x(0) = 0.

x(0) = C = 0

Therefore, the position function is given by:

x(t) = (1/3)t³

To find the total distance traveled, we can find the area under the velocity graph. Since the velocity is always positive, the total distance traveled is the same as the total displacement. Therefore, we can find the displacement by finding the area under the velocity graph from t = 0 to t = T, where T is the time at which the vehicle comes to rest.

v(T) = 0

T² = 0

T = 0

Therefore, the time at which the vehicle comes to rest is T = 0.

The displacement is given by:

x_displacement = ∫v(t)dt from t=0 to t=T = ∫0 dt = 0

Therefore, the total distance traveled is 0 meters.
