Answer:

10 inches

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]

Thus, each side is 10 inches.

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

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%

The decay factor of the exponential function represented by the table is \[tex]( \frac{1}{3} \).[/tex]

The decay factor of an exponential function in the form[tex]\( y = ab^x \)[/tex]is represented by the base, denoted as 'b.' In this scenario, we're given data in a table format. When observing the relationship between the input and output values, notice that as the input increases by 1 unit, the output decreases by a factor of [tex]\( \frac{1}{3} \) ([/tex]e.g., going from 2 to 6, a change in input by 1 unit results in the output decreasing from 6 to 2, a factor of \( \frac{1}{3} \) of the previous output).

The pattern here illustrates a consistent reduction by a factor of [tex]\( \frac{1}{3} \)[/tex]as the input increases. This characteristic aligns with the decay factor in an exponential function, indicating that the base 'b' in the function[tex]\( y = ab^x \) is \( \frac{1}{3} \).[/tex]This base value of[tex]\( \frac{1}{3} \)[/tex] signifies that the function is an exponential decay, where the output diminishes rapidly as the input increases.

Understanding the relationship between the input and output values is crucial in determining the behavior of an exponential function. In this case, recognizing the consistent factor by which the output decreases as the input increases helps identify the decay factor as [tex]\( \frac{1}{3} \),[/tex]indicating the rate of decrease in the exponential decay function.

The consistent reduction by a factor of[tex]\( \frac{1}{3} \)[/tex] establishes the decay pattern in the given exponential function, leading to the conclusion that the decay factor of the function is [tex]\( \frac{1}{3} \).[/tex]

Answer: [tex]\frac{4^{0.5 a}}{2^{b}}=4[/tex]

Step-by-step explanation:

We are told [tex]a-b=2[/tex] being [tex]a[/tex] and [tex]b[/tex] positive integers, hence:

[tex]a=2+b[/tex] (1)

Now we have the following expression:

[tex]\frac{4^{0.5 a}}{2^{b}}[/tex] (2)

Which can be also written as:

[tex]\frac{2^{2(0.5 a)}}{2^{b}}[/tex] (3)

Since [tex]4=2^{2}[/tex]

Then, substituting (1) in (3):

[tex]\frac{2^{2(0.5(2+b))}}{2^{b}}[/tex] (4)

Since we have exponents with the same base, we can do the following:

[tex]\frac{2^{2+b}}{2^{b}}=2^{2+b} 2^{-b}[/tex] (5)

Finally:

[tex]2^{2+b} 2^{-b}=2^{2+b-b}=2^{2}=4[/tex] (6)

Hence:

Answer:

21.25 feet or 255 inches.

Step-by-step explanation:

The first step in this problem is to covert each measurement to the same system of measurement (feet, inches, meters, etc.).

Let's convert 4 inches to feet.

As there are 12 inches in a foot, and 4/12 = 1/3, 4 inches = 1/3 foot.

Now, multiply 1/3 foot by 63 3/4 (the amount of feet in mixed number form).

63 3/4 * 1/3 = 21 1/4, or 21.25.

Therefore, the final answer is 21.25 feet.

If you want the answer in inches, all you have to do is multiply 21.25 by 12, as there are 12 inches in a foot.

21.25*12 = 255.

So, the alternative answer is 255 inches.

Answer:

Soda- 156

Hot Dogs- 52

Step-by-step explanation:

Final answer:

The vendor sold 156 sodas and 52 hot dogs at the basketball game. This was determined by setting up a system of equations using the total number of items sold and the ratio of sodas to hot dogs, then solving for each.

Explanation:

To find the number of sodas and hot dogs sold at the basketball game, we can set up a system of equations based on the information provided:

Let S represent the number of sodas sold.

Let H represent the number of hot dogs sold.

The problem states two key pieces of information:

The total number of sodas and hot dogs sold is 208: S + H = 208.

The number of sodas sold was three times the number of hot dogs sold: S = 3H.

We can substitute the second equation into the first to solve for H:

3H + H = 208

4H = 208

H = 208 / 4

H = 52

Now that we have the number of hot dogs sold (52), we can find the number of sodas sold:

S = 3H

S = 3 \\( 52 \)

S = 156

The vendor sold 156 sodas and 52 hot dogs.

Step-by-step explanation:

If the volumes of two triangular prisms are the same, that means that:

[tex]\frac{1}{3} B_1h_1=\frac{1}{3} B_2h_2[/tex] , where B_1 and h_1 belong to one prism and B_2 and h_2 belong to the second.

It is possible that if the volumes are the same, the prisms are congruent. That means that B_1 = B_2 and h_1 = h_2. However, this isn't always the case. Here's a counterexample:

PRISM 1: B = 4, h = 3  ⇒  V = (1/3) * 4 * 3 = 4

PRISM 2: B = 2, h = 6  ⇒  V = (1/3) * 2 * 6 = 4

Their volumes are the same, but their dimensions certainly aren't. So this statement is true only sometimes.

Final answer:

To find the length of KL in ΔKLM with a 90° angle at M and a 10° angle at K, we use the sine function with the given hypotenuse length of 86 feet. Calculating sin(10°) times 86 gives approximately 14.9296 feet, which rounds to 14.9 feet.

Explanation:

To find the length of KL to the nearest tenth of a foot in ΔKLM, where ∠M equals 90°, ∠K equals 10°, and LM is 86 feet, we can use trigonometry.

Since LM is the hypotenuse and we want to find KL, which is the side opposite ∠K, we will use the sine function:

Calculating this we get:

This provides us with the length of KL in the triangle.

A system of equations is a group of equations that need to be manipulated in some way that will figure out the values of the variables.

The most common system of equations seen is a system of linear equations, which means that the degree of the variables is no more than 1. These can be solved using elimination, substitution, or even graphing, if applicable.

Hope this helps!

Answer:

A system of equations is 2 or more equations that need to be solved. When you solve a system of equations, the answer is where the equations intersect on a graph. Sometimes there is 2 solutions (equations intersect twice), 1 solution (equations intersect once), no solution (equations don't intersect), or infinite solutions ( equations are the same).

They are usually solved using substitution, elimination, or simply looking at a graph to see where the lines intersect.

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.

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.
