Answers

Answer 1

Answer:

4.) 32 answer

Step-by-step explanation:

2×2 is 4

4× 8 is 32

Answer 2
To compute the number of board feet of lumber, we need to first convert the dimensions to feet and then calculate the volume in cubic feet.

Recall that a board foot is a unit of volume equal to 1 foot by 1 foot by 1 inch, or 1/12 cubic foot.

1. 4" x 8" x 12" = (4/12) ft x (8/12) ft x (12/12) ft = 0.222 cubic feet. Therefore, the number of board feet is 0.222 / (1/12) = 2.664 board feet.

2. 3" x 2" x 10" = (3/12) ft x (2/12) ft x (10/12) ft = 0.042 cubic feet. Therefore, the number of board feet is 0.042 / (1/12) = 0.504 board feet.

3. 2" x 4" x 12" = (2/12) ft x (4/12) ft x (12/12) ft = 0.167 cubic feet. Therefore, the number of board feet is 0.167 / (1/12) = 2.004 board feet.

4. 2" x 2" x 8" = (2/12) ft x (2/12) ft x (8/12) ft = 0.022 cubic feet. Therefore, the number of board feet is 0.022 / (1/12) = 0.264 board feet.

5. 4" x 4" x 10" = (4/12) ft x (4/12) ft x (10/12) ft = 0.111 cubic feet. Therefore, the number of board feet is 0.111 / (1/12) = 1.332 board feet.

Therefore, the number of board feet for each dimension are as follows:

1. 2.664 board feet
2. 0.504 board feet
3. 2.004 board feet
4. 0.264 board feet
5. 1.332 board feet

What is value of x in this equation:


4x+15=33-2x

Answers

Answer: Simplifying

4x + 15 = 33 + -2x

Reorder the terms:

15 + 4x = 33 + -2x

Solving

15 + 4x = 33 + -2x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '2x' to each side of the equation.

15 + 4x + 2x = 33 + -2x + 2x

Combine like terms: 4x + 2x = 6x

15 + 6x = 33 + -2x + 2x

Combine like terms: -2x + 2x = 0

15 + 6x = 33 + 0

15 + 6x = 33

Add '-15' to each side of the equation.

15 + -15 + 6x = 33 + -15

Combine like terms: 15 + -15 = 0

0 + 6x = 33 + -15

6x = 33 + -15

Combine like terms: 33 + -15 = 18

6x = 18Divide each side by '6'.

x = 3

Simplifying

x = 3

so X=3 is your answer

XYZ Software employed three different salespeople last year. Person 1

C. $403.00
D. $1128.40

Answers

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:

$282 + $420 + $390 = $1092

Therefore, 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 correct answer is a. True, b. False, c. True, d. True

How to find the mean of regions?The mean of Region 1 is 31+ (32+33+34)×3+35×4+36/15 = 33.6°C

The mean of Region 2 is 36+ 37+ 2x38+ (39+41)x3 +40x4+42/15 = 39.4°C

(The mean = all temperature of region divided by the number of states )

So,  39.4- 33.6 = 5.8 True

The data of Region 2 is more concentrated, So its variability is weaker than Region 3.

So False (variability is comparing the density)

The mean of Region 3 is (32+ 2x (34+35+37+38)+ 36x3+ 39+ 40] ÷15 = 33.8°C

Working alone, Lisa can pick forty bushels of apples in 13 hours. One day her friend Cody helped and it only took them 4.8 hours to do it together. Find out how long it would take Cody to do it alone.

Answers

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

How to find Lisa's individual work?

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.

3. A vehicle starting from rest (v(0) = m/s) at position x = 0 is subjected to the following acceleration, a(t):

A. Use your knowledge of derivatives and or integrals to plot the velocity and clearly indicate the maximum velocity on your graph

B. Given your results of part (a), use your knowledge of derivatives and or integrals to plot the position x (t), and clearly indicate the total distance traveled on your graph

Answers

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.

Find the probability of drawing a green, then yellow, with replacement.
A bag has 4 green blocks, 6 red blocks, 7 blue and 3 yellow.

Answers

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

What is probability?

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.

a truck costs $30,000 and has an estimated life of 5 years with a residual value of $10,000. Prepare a depreciation schedule using the declining-balance method at twice the straight-line rate

Answers

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.

solve for f
f/40 = 10/f​

Answers

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

Answer:

f = 20

Step-by-Step Explanation:

Starting with:

f/40 = 10/f

We can simplify by multiplying both sides by f:

f/40 * f = 10/f * f

f^2 / 40 = 10

Multiplying both sides by 40:

f^2 = 400

Taking the square root of both sides, remembering to consider both the positive and negative roots:

f = ±20

So the two possible solutions are f = 20 or f = -20.

The surface area of the cylinder to the nearest square meter include the following: C. 160 square meters.

How to calculate surface area of a cylinder?

In Mathematics and Geometry, the surface area (SA) of a cylinder can be calculated by using this mathematical equation (formula):

SA = 2πrh + 2πr²

Where:

h represents the height.r represents the radius.

By substituting the given parameters into the formula for the surface area (SA) of a cylinder, we have the following;

Surface area = 2πrh + 2πr²

Surface area = 2(3.14)(2.8)(6.3) + 2(3.14)(2.8²)

Surface area = 160 square meters.

Therefore, the value of f(m-2) is 5/(m-2) + 2, and the value of function g(1/2) is 2.

What is function?

In mathematics, a function is a rule or correspondence between two sets, where each input value from the first set (called the domain) corresponds to exactly one output value in the second set (called the range). A function is often represented by a formula, equation, or graph.

Here,

1. To find f(m-2), we substitute (m-2) for x in the expression for f(x):

f(m-2) = 5/(m-2) + 2

So the value of f(m-2) is 5/(m-2) + 2.

2. To find g(1/2), we substitute 1/2 for x in the expression for g(x):

g(1/2) = -2(1/2) + 3

So the value of g(1/2) is -1 + 3, which simplifies to 2.

At the store, 60% of the customers are parents and 40% of the customers are not. The average age of the parents is 52 years old. The average age of those not parents is 20 years old.

Answers

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

How to find the average age ?

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

In a small town, all 100 residents live on the west side of town, and they work on the east side of town. People may choose to drive to work, which costs $2 worth of fuel per round trip. There is no overnight parking at work, so anybody driving will drive a round trip. The supply of fuel is perfectly elastic at $2 per the amount required for a round trip. The only downside to driving is that every round trip generates pollution worth $0.03. That pollution affects each and every resident of the small town (for simplicity assume that it even impacts the driver). The other transportation alternative is a free electric tram. It is a good thing the tram is free because people are not willing to pay to take the tram.
