What is the measure of angle 3?
Mark this and return
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
∠ 3 = 25°
A cube-shaped box has a volume of 1,000 cubic inches. What is the length of each side of the box?
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.

Determine whether each statement is sometimes, always, or never true.
If the volumes of two triangular prisms are the same, the prisms are congruent.
Answer:
Sometimes
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.
Hope this helps!
Answer:
Sometimes true
Step-by-step explanation:
Volume = ⅓(base area × height)
The product 'base area × height' can be equal if the base and height are congruent, but there are other possibilities too

Base area of the second one is double but the height is half.

If the risk-free rate is 4% and the market risk premium is 5.5%, what is Cheyenne’s portfolio’s beta and required return?
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%
What is portfolio beta and the required return rate?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)

What is the decay factor of the exponential function represented by the table? One-third Two-thirds 2 6
The decay factor of the exponential function represented by the table is \[tex]( \frac{1}{3} \).[/tex]
Explanation: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]
The decay factor of the exponential function is 1/3
How to determine the decay factor of the exponential function
From the question, we have the following parameters that can be used in our computation:
The table of values
Where, we have
f(0) = 6
f(1) = 2
The decay factor (k) of the exponential function is calculated as
k = f(1)/f(0)
Substitute the known values into the equation
k = 2/6
Evaluate
k = 1/3
Hence, the decay factor of the exponential function is 1/3

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.
Explanation: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).

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.

Step-by-step explanation:
A planter in the shape of a square pyramid is being filled with soil. Soil cost $0.78 per cubit cubic foot. What is the cost of filling the planter with soil?
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.
Explanation: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.

If the scale of a flag from the image to the actual were 1 inch = 63.75 ft, what would the actual width of a large American flag measure if on the image the flag is 4 inches wide?
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.
Find the upper bound for 96.3cm measured to the nearest tenth of a cm
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.
