The sum of all edges of the regular quadrilateral pyramid depends on the length of the base edges and the height of the pyramid.

To find the sum of all edges of the regular quadrilateral pyramid, we need to find the length of the edges. Let's denote the length of the edge of the base by 'a'. Since the base of the pyramid is a regular quadrilateral, all its sides are equal. Therefore, the perimeter of the base is given by P = 4a = 30 cm.

Dividing both sides of the equation by 4, we get a = 7.5 cm.

Since the perimeter of a lateral face is 27.5 cm, the length of each lateral edge is equal to the height of the pyramid. Therefore, the sum of all edges of the pyramid is 4a + 4h, where 'h' is the height of the pyramid.

So, the sum of all edges is 4(7.5 cm) + 4h = 30 cm + 4h.

Answer:

The expression that shows how much profit Jessique will earn in

1 month is ⇒ Profit = 46x - 1000

Step-by-step explanation:

* Lets revise the relation between selling price , cost price and profit

- Profit is the difference between the selling price and the cost price

- Profit = selling price - cost price

- Jessique sells handbag for $50 each

- The selling price of each handbag is $50

- She spends $4 per handbag for materials

- She spends $1000 to rent a store each month

- She sells x amount of handbags in one month

* Lets calculate the cost price of the x handbags in 1 month

∵ She spends $4 per handbag for materials

∴ She spends on the materials of x handbag = 4 × x = 4x

∵ She spends $1000 to rent a store each month

∴ The cost price of x handbags in 1 month = 4x + 1000

∵ She sells x handbags in 1 month

∵ The selling price of 1 handbag is $50

∴ The selling price of x handbags in 1 month = 50 × x = 50x

∵ Profit = selling price - cost price

∴ Profit = 50x - (4x + 1000) ⇒ multiply the bracket by (-)

∴ Profit = 50x - 4x - 1000 ⇒ add like terms

∴ Profit = 46x - 1000

* The expression that shows how much profit Jessique will earn in

 1 month is Profit = 46x - 1000

Final answer:

Jessique's profit for selling x handbags in one month is represented by the expression 46x - 1000, where x is the number of handbags sold.

Explanation:

Jessique sells handbags for $50 each. She spends $4 per handbag for materials and $1000 to rent a store each month. To calculate Jessique's profit for selling x handbags in a month, you would subtract both the materials cost and the fixed store rent from her total sales.

The total sales from x handbags is $50 times x, or $50x. The cost of materials for x handbags is $4 times x, or $4x. The fixed store rent is $1000 every month, regardless of how many handbags are sold.

Therefore, to find her profit, the expression is:

Profit = Total Sales - Materials Cost - Fixed Rent
Profit = (50x) - (4x) - 1000

Simplifying this expression, her profit for x handbags in a month would be:

Profit = 46x - 1000

The equation to find the total number of castles conquered by Jackson is 15 + 3x, where x represents the remaining levels. Jackson has conquered 15 castles in 5 levels and will conquer 3 more for each additional level he completes.

The question relates to creating an equation to find the total number of castles Jackson will have conquered after completing all levels in a video game. Jackson has completed 5 levels, and there are 3 castles within each level. If x represents the remaining levels to complete, we can create the equation by considering the total number of castles conquered in the levels completed (5 levels × 3 castles/level = 15 castles) and adding it to the castles that will be conquered in the remaining levels (x levels × 3 castles/level). The equation representing the total number of castles Jackson will have conquered once he completes the final level is:

Total castles = (5 × 3) + (x × 3) = 15 + 3x

As a separate example unrelated to Jackson's equation, there is the classical problem involving grains of rice and a chessboard that demonstrates exponential growth. In this example, one grain of rice is placed on the first square of a chessboard, and the number of grains is doubled on each subsequent square. By the 64th square, you are placing a very large number of grains, and the total number minus one grain would be 264 - 1. However, the actual number of grains needed is a separate calculation from the equation for Jackson's video game question.

Step-by-step explanation:

The expression can be simplified using the distributive property, but it is not in its simplest form, Option A is correct.

An expression is combination of variables, numbers and operators.

The expression 6x + (9+3x) is in the distributive property.

To see why, we can apply the distributive property of multiplication over addition, which states that a(b + c) = ab + ac. In this case, we have:

6x + (9+3x) = 6x + 9 + 3x

Here, the expression 6x is being distributed over the parentheses, which contain 9 and 3x. We can combine the constants 6x and 9, as well as the like terms 6x and 3x, using the commutative and associative properties of addition:

6x + 9 + 3x

= 6x + 3x + 9

= (6x + 3x) + 9

= 9x + 9

So, the expression can be simplified using the distributive property, but it is not in its simplest form.

There should be 23 students from Ms. Gardner’s class in the play.

To determine why there must be exactly 23 students in Ms. Gardner's class and to find out how many students from Ms. Gardner's class are in the play, let's break down the problem step-by-step.

  - Let L be the number of students in Mr. Logan's class.

  - Let G be the number of students in Ms. Gardner's class.

  - Let C be the number of students in Mrs. Cho's class.

  - Let [tex]P_L[/tex] be the number of students from Mr. Logan's class in the play.

  - Let [tex]P_G[/tex] be the number of students from Ms. Gardner's class in the play.

  - Let [tex]P_C[/tex] be the number of students from Mrs. Cho's class in the play.

  - L = 23

  - [tex]P_L[/tex] = 7

  - There are 4 more students from Ms. Gardner's class in the play than from Mrs. Cho's class: [tex]P_G[/tex] = [tex]P_C[/tex] + 4

[tex]P_G[/tex]

  - The number of students in the play from Mr. Logan's class is greater than the number from Mrs. Cho's class and fewer than the number from Ms. Gardner's class: [tex]P_C[/tex] < 7 < [tex]P_G[/tex]

  - 30% of the students in these three classes are in the play.

  - Total students in these three classes: L + G + C

  - Total students in the play: [tex]P_L[/tex] + [tex]P_G[/tex] + [tex]P_C[/tex]

30% of the Students are in the Play:

  - 0.30 (L + G + C) = [tex]P_L[/tex] + [tex]P_G[/tex] + [tex]P_C[/tex]

0.30 (23 + G + C) = 7 + [tex]P_G[/tex] + [tex]P_C[/tex]

Using [tex]P_G[/tex] = [tex]P_C[/tex] + 4 :

0.30 (23 + G + C) = 7 + ([tex]P_C[/tex] + 4) + [tex]P_C[/tex]

0.30 (23 + G + C) = 7 + [tex]P_C[/tex] + 4 + [tex]P_C[/tex]

0.30  (23 + G + C) = 11 + 2[tex]P_C[/tex]

0.30 (23 + G + C) = 11 + 2[tex]P_C[/tex]

0.30 × 23 + 0.30G + 0.30C = 11 + 2[tex]P_C[/tex]

6.9 + 0.30G + 0.30C = 11 + 2[tex]P_C[/tex]

0.30G + 0.30C = 11 + 2[tex]P_C[/tex] - 6.9

0.30G + 0.30C = 4.1 + 2[tex]P_C[/tex]

G + C = [tex]\frac{4.1 + 2P_C}{0.30}[/tex]

G + C = [tex]\frac{4.1}{0.30} + \frac{2P_C}{0.30}[/tex]

G + C = [tex]\frac{41}{3} + \frac{20}{3}P_C[/tex]

G + C = [tex]\frac{41 + 20P_C}{3}[/tex]

[tex]P_G[/tex] = 7

[tex]P_C[/tex] = [tex]P_G[/tex] - 4 = 7 - 4 = 3

So,

G + C = [tex]\frac{41 + 20 \cdot 3}{3} = \frac{41 + 60}{3} = \frac{101}{3}[/tex]

G + C = 33.67

Since G and C must be integers and they add up to 33.67, we need to check for plausible values of G and C. However, considering our assumptions and given constraints, we should use consistent integer values:

For:

[tex]P_G[/tex] = 7

[tex]P_C[/tex] = 3

0.30(23 + G + C) = 7 + 7 + 3

0.30(23 + G + C) = 17

Thus:

23 + G + C = [tex]\frac{17}{0.30}[/tex]

23 + G + C = 56.67

So:

G + C = 56.67 - 23 = 33.67

Given [tex]P_C[/tex] < 7 < [tex]P_G[/tex], by resolving as integers:

G = 23

C = 11

Thus, Ms. Gardner's class must have 23 students.

The problem involves using trigonometry, specifically the tangent function, to determine the distance between the two ships. By calculating the distance from the observer to each ship separately and finding the difference, we find the distance between the two ships to be approximately 814.61 feet.

The problem at hand involves the use of trigonometry, specifically tangent of an angle in a right triangle. Since we are dealing with angles of depression, we must understand that these angles are taken from a horizontal line - in this case, the line of sight from the cliff's edge.

First, let's consider the observer and the further away ship using tangent as follows:

Similar steps for nearer ship with angle of 48 degrees:

Therefore, the distance between the ships is the difference between the two distances calculated above, which will be 1809.54 - 994.93 = 814.61 feet.

To determine the distance between the two ships, use the angles of depression and the observer's height above sea level to find the horizontal distances to each ship with trigonometry and subtract the smaller from the larger.

To calculate the distance between two ships using their angles of depression from an observer's viewpoint atop a cliff, we can employ trigonometry. Let us denote the observer's vertical distance above sea level as height (h), which is 1200 feet in this case. The angles of depression to the first and second ship are 48° and 33° respectively.

We will use the tangent of these angles to find the horizontal distances (d1 and d2) from the base of the cliff to each ship:

After finding d1 and d2, we subtract the smaller distance from the larger to get the distance between the two ships:

Distance between ships = d2 - d1

Finally, we convert the answer from feet to the desired unit if necessary.

Step-by-step explanation:

d=a(2+kt)

WE need to solve for k. our aim is to get K alone

d= a(2+kt)

To eliminate 'a' we divide by 'a' on both sides

[tex]\frac{d}{a} = 2+ kt[/tex]

To eliminte 2 we subtract 2 on both sides

[tex]\frac{d}{a}-2 =kt[/tex]
