Answer:

It should be d, The bases do not have the same area because the volumes are not the same.

Step-by-step explanation:

did it on the unit review test

The bases do not have the same area because the volume of the cylinder is not 3 times the volume of the cone, given the same heights.

The volume of a cone is given by the formula:

A = πr²h/3

The volume of a cylinder is given by the formula:

A = πr²h

It is given that the height of both the cylinder and the cone is the same.

This means that the only way variable that influences the volume is the radius of the base.

The volume of the cylinder is three times the volume of the cone when the radius and height are equal.

But the volume of the cylinder is two times the volume of the cone in the given question.

This means that they have different radii which means that the bases are different.

Therefore, we have found that the bases do not have the same area because the volume of the cylinder is not 3 times the volume of the cone, given the same heights. The correct answer is option D.

Amber will have to draw a straight line graph with equation y = 4x and the point where the straight line and the curve intersects is the solution

To solve the equation 3x² - 4x = 0 graphical, the curve will be plotted and the point of intersection with the x axis is the zero, or solution of the graph.

Using Amber's method we have that

y = 3x² - 4x = 0

3x² = 4x

There fore y = 3x²and y = 4x. The both graph will be plotted and their point of intersection, will be the solution of the problem.

The solution of the graph is

y = 3x²and y = 4x: (0, 0) and (1.33, 5.33)

3x² - 4x: (0, 0) and (1.33, 0)

Both has same x values of 0 and 1.333

Central Idea of the Poem; In the poem ‘Animals’, the poet Walt Whitman praises animals for being better than human beings and for possessing all such qualities that humans lack or have forgotten.

The poem Animals' central theme is that humans might get wisdom and virtues from the animals they formerly owned but have since lost.

The poet claims that animals possess many admirable traits like self-control, impartiality, and tranquility.

The comparison of people to animals in order to emphasize the shortcomings in human nature is the poem's main focus rather than praising how wonderful animals are.

The poet thinks that possibly people once possessed all of the virtues listed above, but that they have since lost them.

To calculate the mean absolute deviation (MAD), the steps are as follows:

The first step is to find the average of the data set by summing all the values and dividing by the total number of values. The arithmetic mean represents the central tendency of the data set.

After calculating the mean, you need to find the absolute difference between each data point and the mean. To do this, subtract the mean from each individual value and take the absolute value (ignoring the sign). This step measures the deviation of each data point from the mean, regardless of whether the value is above or below the mean.

Once you have obtained the absolute differences for each data point, add them all together. This step involves summing the absolute values of the deviations calculated in the previous step. The result is a single value that represents the total deviation from the mean for the entire data set.

Finally, divide the sum of absolute differences by the number of data points in the sample (if it's a sample MAD) or the population (if it's a population MAD).

This step computes the average deviation by dividing the total deviation by the number of data points. It gives you the mean absolute deviation, which represents the average amount by which each data point deviates from the mean.

Answer:

The computer will be worth $1,850 after four years.

Step-by-step explanation:

We need to find 6.5% of $2,500.

2,500 x 0.065 = $162.50

Therefore, the computer value decreases by $162.50 each year. Since we need to know the computer value after 4 years, we also need to multiply the value of decrease by 4.

162.5 x 4 = $650

Therefore, after 4 years, the computer value will decrease by $650.

To find the whole computer value after 4 years, we need to subtract the initial value of $2,500 by the 4-year decreasing value of $650.

2,500 - 650 = $1850

Therefore, the computer will be worth $1,850 after four years.

The required white effective interest rate is 0.71% more than his nominal interest rate.

Compound interest is the interest on deposits computed on both the initial principal and the interest earned over time.

Here,

White Effective interest R,
\(R=(1+i/m)^m)-1\\R=(1+0.1362/4)^4)-1\\R =0.1433*100=\)
R = 14.33 percent

So

Difference in interest = 14.33%-13.62%
                                    =0.71%

Thus, the required white effective interest rate is 0.71% more than his nominal interest rate.

The BMI of an 118-lb adult who is 5 feet 4 inches tall is approximately 20.25.

BMI stands for Body Mass Index.

It's a measure of body fat based on height and weight that applies to both adult men and women.

BMI is an easy-to-perform screening tool for body fat levels that can help identify individuals who have health risks linked with excess body fatness.

It's important to keep in mind that the BMI measurement should not be used as a diagnostic tool for health conditions and is only one component in an overall evaluation of a person's health status.

Using the formula below, we can calculate the BMI of an 118-lb adult who is 5 feet 4 inches tall: BMI = (weight in pounds / (height in inches x height in inches)) x 703

First, we need to convert the height into inches:5 feet 4 inches = 64 inches

Next, we plug the values into the formula and solve for the BMI:

BMI = (118 / (64 x 64)) x 703BMI = (118 / 4,096) x 703BMI = 0.0288 x 703BMI = 20.2464

Therefore, the BMI of an 118-lb adult who is 5 feet 4 inches tall is approximately 20.25.

Maria must cut an additional $70 from her expenses each month in order to save enough money to buy a new TV that costs $420 in 6 months. By allocating this additional amount towards her savings goal, she will be able to reach her target within the desired timeframe. It's important for Maria to review her budget and identify areas where she can reduce expenses in order to make room for the additional savings. This could involve cutting back on discretionary spending, finding ways to save on daily expenses, or exploring opportunities to increase her income.

Maria must cut an additional $70 from her expenses each month.

To determine how much additional money Maria must cut from her expenses each month to afford a new TV that costs $420 in 6 months, we divide the total cost by the number of months.

Additional money per month = Total cost / Number of months

Additional money per month = $420 / 6

r = \(\frac{a_{2} }{a_{1} }\) = \(\frac{-32}{128}\) = - \(\frac{1}{4}\)

There are 107 different methods to disembark.

When you mention "no two folks exit on the same floor," I suppose you mean that each of the seven people exits the elevator on a different floor.

The first person can exit the elevator on any of the building's 10 levels, followed by the second person on any of the other 9 floors, and so on.

The total number of ways in which the 7 people can exit the elevator from different floors is 10P7 ways.

The first person, as well as the second, third, and other people, can exit from any of the ten floors, thus we take this into consideration when calculating the overall number of exits. Therefore, there are 107 different methods to disembark.
