To calculate the cost of filling a planter in the shape of a square pyramid, first, find the volume of the planter using the volume formula of a pyramid (1/3*Base Area*Height) then multiply the volume with the cost of the soil per cubic foot.

To calculate the cost of filling the planter with soil, we first need to know the volume of the square pyramid. The formula to calculate the volume of any pyramid is 1/3*Base Area*Height. Once we know the volume, we can multiply it by the cost of the soil per cubic foot, which in this case is $0.78.

For instance, if the volume of your pyramid planter was 10 cubic feet, you would calculate 10 * $0.78 = $7.80. Therefore, in our example, it would cost you $7.80 to fill your square pyramid planter with soil.

Answer:

About 28.26 inches.

Step-by-step explanation:

The formula for circumfrence is c = 2(pi) * r.

We know that r = 4.5 (because the diameter is 9 inches).

So, the equation is c = 2(pi) * 4.5

Let's solve:

c = (2*3.14) * 4.5

c = 6.28 * 4.5

c = 28.26

Therefore, the final answer is 28.26 inches.

Of course, this is not exact because pi is irrational and goes on forever, but the question is asking for an estimate anyways.

Answer:

8.1

Step-by-step explanation:

1) There are 360 degrees in a circle.  Therefore, the arc measure of PQ would be 360-(73+150+65)= 72.  

2) The intercepted arc is the same measure as the central, making it 72.  Therefore it takes up 72/360 of a circle or 1/5.  

3) To find the measure of it, you would find 1/5 of the circumference.  C=2πr . C=2(3.14)(6.48)≈ 40.7 .

4) 1/5 of the circumference would be (40.7)/(5)≈8.1

Step-by-step explanation:

take the cube root of the volume to find the lenght of each side.

Answer:

10 inches

Step-by-step explanation:

The volume of a cube is of the form: [tex]V=s^3[/tex] , where s is the side length.

Here, we know the volume V, but not the side length. So, we can plug in the value 1000 in for V and solve for s:

1000 = [tex]s^3[/tex]

Cube root both sides:

s = [tex]\sqrt[3]{1000} =10[/tex]

The question is about solving a system of equations representing the sales of adult and child tickets. You would use either substitution or elimination methods to find the individual prices of the adult (A) and child (C) tickets.

The subject of your query pertains to system of equations. In this problem, we can establish two equations based on the information provided: 4A + C = 55 and 3A + 2C = 50, where A represents the cost of an adult ticket and C is the cost of a child ticket. We can solve this using the substitution or elimination method. If we solve the first equation for A, we will obtain A = (55-C)/4. Substituting this into the second equation gives us 3((55-C)/4) + 2C = 50. Simplifying and solving this equation will provide us with the cost of the child ticket (C), which we can then substitute back into one of our original equations to find the price of an adult ticket (A).

The complete question says: "Cheyenne holds a $7,500 portfolio that consists of four stocks. Her investment in each stock, as well as each stock’s beta, is listed in the following table:"  The complete table for the question can be seen in the image attached below.

Cheyenne’s portfolio’s beta is 0.965 and the required return is 9.31%

A portfolio's beta is the model that measures the stock's return while estimating the market risk.

The required rate of return is the minimal return an investment will take for holding a company's shares in exchange for taking on a certain amount of risk.

The formula for calculating Portfolio's Beta is:

= Sum of (Beta × Weights)

[tex]\mathbf{= (1 \times (\dfrac{2625}{7500})) + (1.50 \times (\dfrac{1500 }{ 7500})) + (1.10 \times (\dfrac{1125 }{ 7500})) + (0.50 \times (\dfrac{2250 }{ 7500}))}[/tex]

= 0.35 + 0.30 + 0.165 + 0.15

= 0.965

Required Return = Risk Free Rate + (Beta × Premium Market Risk)

= 4% + (0.965 × 5.5%)

= 0.04 + (0.965 × 0.055)

= 9.31%

Answer:

∠ 3 = 25°

Step-by-step explanation:

The sum of the 3 angles 85, 2x and x - 10 are a straight angle = 180°

85 + 2x + x - 10 = 180, that is

3x + 75 = 180 ( subtract 75 from both sides )

3x = 105 ( divide both sides by 3 )

x = 35

Thus x - 10 = 35 - 10 = 25

∠ 3 and x - 10 are Alternate angles and congruent, thus

Just took the quiz and got it right

The statement that shows a negative rate of change for the interval 0 to 2 on the x-axis is option C; On a coordinate plane, a parabola opens up. It goes through (negative 1, 4), has a vertex of (2.5, 0.25), and goes through (5.8, 4).

Suppose that we have to measure the rate of change of y as x changes, then we have:

[tex]Rate = \dfrac{y_2 - y_1}{x_2 - x_1}[/tex]

Remember that, we divide by the change in independent variable so that we get some idea of how much the dependent quantity changes as we change the independent quantity by 1 unit.

Answer:

The number of guppies were in the shop in the beginning = 60

Step-by-step explanation:

guppies ⇒ x , angelfish ⇒ y , goldfish ⇒ z

guppies to angelfish = 2 : 3 ⇒ x : y = 2 : 3 ⇒ x = 2/3 y

The number of angelfish was 2/3 the number of goldfish ⇒ y = 2/3 z

Or z = 3/2 y

The shopkeeper decided to replace 1/4 of the guppies with some angelfish. The number of angelfish she added was equal to the number of guppies she replaced

so, the number of guppies = 0.75x

and the number of angelfish = y + 0.25 x = y + 0.25 * 2/3 y

There were 30 more goldfish than angelfish in the end

z - (y + 0.25 * 2/3 y) = 30

so, 3/2 y - (y + 0.25 * 2/3 y) = 30

3/2 y - y - 1/6 y = 30

1/3 y = 30

y = 90

x = 2/3 y =2/3 * 90 = 60

z = 3/2 * 90 = 135

so, the number of guppies were in the shop in the beginning = 60

Final answer:

By setting up variables for the number of guppies (G) and angelfish (A) and establishing equations based on the given ratios, we can determine that the shop initially had 40 guppies.

Explanation:

To determine how many guppies were in the shop originally, let's set up variables for the number of guppies (G) and angelfish (A). According to the information provided, the ratio of guppies to angelfish is 2:3, which can be represented by the equation G/A = 2/3. The number of angelfish was also 2/3 the number of goldfish (F), meaning A = (2/3)F. When 1/4 of the guppies are replaced with angelfish, the number of guppies becomes 3/4G, and the number of angelfish becomes A + 1/4G. In the end, we are told there are 30 more goldfish than angelfish. Therefore, we have F = A + 30.

From A = (2/3)F and F = A + 30, we can substitute (2/3)F for A in the second equation, yielding F = (2/3)F + 30. Solving this equation for F gives us F = 90. Using the earlier equation A = (2/3)F, we find A = 60. Now, since A was 2/3 the number of goldfish originally, and using G/A = 2/3, we solve for G by setting up the equation G/60 = 2/3, leading to G = 40. Hence, there were 40 guppies in the shop initially.

Final answer:

The upper bound for 96.3 cm, measured to the nearest tenth of a cm, is 96.4 cm. This represents the highest possible value that would round down to 96.3 cm.

Explanation:

The student is asking to find the upper bound for the measurement of 96.3 cm, given that it is measured to the nearest tenth of a cm (centimeter). When measurements are taken to the nearest tenth, this indicates that the actual length could be anywhere from the stated length up to, but not including, 0.1 cm greater. To find the upper bound, you would add 0.1 cm to the stated measurement without including it, meaning the maximum possible actual length just before it would round up to the next tenth of a cm.

To calculate the upper bound for 96.3 cm, you simply add 0.1 cm to it:
96.3 cm + 0.1 cm = 96.4 cm
So, the upper bound is 96.4 cm, as that is the largest value that would still round down to 96.3 cm when measured to the nearest tenth of a cm.
