The height of the prism is 4ft

A prism is a solid shape that is bound on all its sides by plane faces. There are two types of faces in a prism. The top and bottom faces are identical and are called bases. A prism is named after the shape of these bases. For example, if a prism has a triangular base it is called a triangular prism.

A rectangular prism is known as cuboid

surface area of a cuboid = 2(lb +lh +bh)

52 = 2( 2×3 + 2h.+3h)

(6+ 2h.+3h) = 52/2

6+5h = 26

5h = 26-!6

5h = 20

divide both sides by 5

h = 20/5

h = 4ft

therefore the height of the prism is 4

Answer:

Step-by-step explanation:

A and B are wrong and with D they wouldn't be lines so imma go with C.

Sorry if it's wrong.

Answer:

Step-by-step explanation:

\(y = \frac{1}{3} x +4\) , \(slope, m_1 = \frac{1}{3}\)

Let the slope of the new line be \(m_2\)

Since the lines are parallel , \(m_1 = m_2\)

                                               \(m_2 = \frac{1}{3}\)

\((x_1, y_1) = (-3, 1) \ , \ m_2 = \frac{1}{3}\\\\Equation \ of \ the \ new \ line : (y - y_1) = m(x - x_1)\)

                                        \(y - 1 = \frac{1}{3}(x -(-3)) \\\\y - 1 = \frac{1}{3}(x +3)\\\\y - 1 =\frac{1} {3}x + 1 \\\\y = \frac{1}{3}x + 2\)

Response to the given question would be that Hence, the surface area rectangular box has a surface area of 592 square cm.

Surface area is a measure of how much space an object's surface takes up overall. The total area of a three-dimensional shape's surroundings is its surface area. Surface area refers to the total surface area of a three-dimensional form. You may compute the surface area of a cuboid with six rectangular sides by adding together their individual areas. Instead, you may use the following formula to name the box's dimensions: Surface (SA) = 2lh plus 2lw plus 2hw. A three-dimensional shape's surface area is calculated as the total amount of space it occupies (a three-dimensional shape is a shape that has height, width, and depth).

Size (l) equals 10 cm

Height (h) = 8 cm

Size (h) equals 12 cm

We may use the following formula to get the box's surface area:

Surface Area = 2(lh, lw, and wh)

Inputting the values provided yields:

Surface Area equals 2 (10 x 8, 10 x 12, and 8 x 12) square centimetres.

Surface Area is equal to 2 (80, 120, and 96 square cm).

Surface Area: 2(296) square centimetres

592 square cm is the surface area.

Hence, the rectangular box has a surface area of 592 square cm.

Dante and Mia lost a total of 100 + 50 = 150 pennies.

Let's denote the number of pennies Dante initially had as "D" and the number of pennies Mia initially had as "M." According to the given information, we know that D + M = 350.

After Dante lost half of his pennies, he would have (1/2)D pennies remaining, and after Mia lost one-third of her pennies, she would have (2/3)M pennies remaining. It is stated that they both had an equal number of pennies after these losses.

Therefore, we can set up the following equation:

(1/2)D = (2/3)M

To simplify this equation, we can multiply both sides by 6 to eliminate the fractions:

3D = 4M

Now we have a system of equations:

D + M = 350
3D = 4M

We can solve this system to find the values of D and M. Multiplying the first equation by 4, we get:

4D + 4M = 1400

Substituting 3D for 4M from the second equation, we have:

4D + 3D = 1400
7D = 1400
D = 200

Substituting D = 200 back into the first equation, we find:

200 + M = 350
M = 150

So, Dante initially had 200 pennies, and Mia initially had 150 pennies.

To find out how many pennies they lost, we need to calculate the difference between their initial amounts and their final amounts:

Dante lost: 200 - (1/2)D = 200 - (1/2)(200) = 200 - 100 = 100 pennies
Mia lost: 150 - (2/3)M = 150 - (2/3)(150) = 150 - 100 = 50 pennies

Therefore, Dante and Mia lost a total of 100 + 50 = 150 pennies.

Answer:

3628800 ways if the women are always required to stand together.

To solve this problem, we can consider the number of ways to arrange the women and men separately, and then multiply the results together.

First, let's consider the arrangement of the women. Since no two men can be seated next to each other, the women must be seated in between the men. We can think of the 5 men as creating 6 "gaps" where the women can be seated (one gap before the first man, one between each pair of men, and one after the last man).

Out of these 6 gaps, we need to choose 7 gaps for the 7 women to sit in. This can be done in "6 choose 7" ways, which is equal to the binomial coefficient C(6, 7) = 6!/[(7!(6-7)!)] = 6.

Next, let's consider the arrangement of the 5 men. Once the women are seated in the chosen gaps, the men can be placed in the remaining gaps. Since there are 5 men, this can be done in "5 factorial" (5!) ways.

Therefore, the total number of ways to seat the 5 men and 7 women is 6 * 5! = 6 * 120 = 720.

There are 720 ways to seat the 5 men and 7 women in a row such that no two men are next to each other.

The correct option is that, No, the Large Counts Condition is not met.

Conditions for inference are the three conditions on a mean are randomness, whether it is normal distribution and the independence of the test.

Given that,

The reporter selects a random sample of 50 American adults and finds that 28 are unable to name the current vice president.

So the sample is random.

10% condition is also met since the sample size is 50, which must be less than 10% of the total population.

So the 10% condition is also met.

Large counts condition is the condition which requires the sample size to be large enough for the distribution to be approximately normal.

To determine which proposal(s) to select, we need to compare the present worth or net present value (NPV) of each proposal. The NPV represents the difference between the present value of cash inflows and outflows for each proposal.

For independent proposals at MARR = 15.5% per year:

Calculate the NPV for each proposal using the cash inflows and outflows and discounting them to present value using the MARR of 15.5%.

Select the proposal(s) with a positive NPV. Positive NPV indicates that the project's expected cash inflows exceed the initial investment and the MARR.

For mutually exclusive proposals at MARR = 10% per year:

Calculate the NPV for each proposal using the cash inflows and outflows and discounting them to present value using the MARR of 10%.

Select the proposal with the highest positive NPV. The proposal with the highest positive NPV indicates the project that generates the highest expected return or value relative to the MARR.

For mutually exclusive proposals at MARR = 14% per year:

Calculate the NPV for each proposal using the cash inflows and outflows and discounting them to present value using the MARR of 14%.

Select the proposal with the highest positive NPV. The proposal with the highest positive NPV indicates the project that generates the highest expected return or value relative to the MARR.

It's important to note that the specific details of the proposals, including cash inflows, outflows, and timing, are needed to calculate the NPV accurately. Without this information, it is not possible to provide a definitive answer.

we have 3x + 4y = 7

4y = -3x + 7

y = -3/4 x + 7/4

so slope is -3/4

2 parallel lines always have same slope

so the slope of our new line is -3/4

so y = -3/4 x + C

for c,

we have (x,y) = (-2/3,7/8)

7/8 = -3/4 * -2/3 + C

C = 3/8
