The volumes of two similar prisms are 135 ft^3 and 5000ft^3
a. Find the ratio of their heights.
b. Find the ratio of the area of their bases.
The ratio of the areas of the bases of the two similar prisms is approximately 26 to 1.
What is the scale factor?
A scale factor is defined as the ratio between the scale of a given original object and a new object, which is its representation but of a different size (bigger or smaller).
Let h1 and h2 be the heights of the two similar prisms, and let A1 and A2 be the areas of their respective bases.
Also, let k be the scale factor that relates the smaller prism to the larger prism.
a. We know that the volumes of the two similar prisms are proportional to the cubes of their corresponding side lengths, so we have:
(kh1)³ / (kh2)³ = 135 / 5000
Simplifying this expression, we get:
h1³ / h2³ = 135 / 5000
Taking the cube root of both sides, we get:
[tex]h1 / h2 = (135 / 5000)^{(1/3)}[/tex]
Using a calculator, we find:
h1 / h2 ≈ 0.405
Therefore, the ratio of the heights of the two similar prisms is approximately 0.405 to 1.
b. The ratio of the areas of the bases of two similar prisms is equal to the square of the scale factor. That is:
A1 / A2 = k²
To find the scale factor k, we can use the fact that the volumes of the two prisms are proportional to k³. Therefore:
k³ = 5000 / 135
k ≈ 5.091
Using this value of k, we get:
A1 / A2 = k² = (5.091)² ≈ 26
Therefore, the ratio of the areas of the bases of the two similar prisms is approximately 26 to 1.

The total revenue for a bluetooth speaker (in dollars) is given by R(x)=35x−0. 01x2 where x is the number of units sold. What is the average rate of change in revenue as the number of bluetooth speakers sold increases from 20 to 40 units?
The average rate of change in revenue as the number of bluetooth speakers sold increases from 20 to 40 units is $34.50 per unit.
To find the average rate of change in revenue, we need to calculate the change in revenue over the change in units sold.
First, let's calculate the revenue for 20 and 40 units sold:
R(20) = 35(20) - 0.01(20)^2 = $670
R(40) = 35(40) - 0.01(40)^2 = $1360
Now we can calculate the change in revenue:
ΔR = R(40) - R(20) = $1360 - $670 = $690
And the change in units sold:
Δx = 40 - 20 = 20
Finally, we can calculate the average rate of change in revenue:
ΔR/Δx = $690/20 = $34.50

Mr. and Mrs. Johnson took their three children to the movies. If adult tickets cost $7 and children's tickets cost $4, what is the ratio of the total cost of the parents' tickets to the total cost of the children's tickets? Write your answer in the form aib, where a and b are whole numbers.
Let's assume that Mr. and Mrs. Johnson bought x adult tickets and y children's tickets.
Since there are three children, we know that:
y = 3x
The total cost of the parents' tickets is 7x, and the total cost of the children's tickets is 4y. Substituting y = 3x, we get:
total cost of parents' tickets = 7x
total cost of children's tickets = 4(3x) = 12x
Therefore, the ratio of the total cost of the parents' tickets to the total cost of the children's tickets is:
(7x) / (12x) = 7/12
So the answer is 7/12, which cannot be simplified further. Therefore, the ratio is 7/12, which can be written in the form aib as 0+7/12i.
Answer: 7:6
Step-by-step explanation:
1. There are two adults (Mr. and Mrs. Jonhson) and three children. So let's make adults = y and children = x
2. Adult tickets cost $7. So we are going to multiply 7 x 2y = $14
3. Children's tickets cost $4. So we are going to multiply 4 x 3x = $12
4. The last step is to fully reduce [tex]\frac{14}{12}[/tex] = [tex]\frac{7}{6}[/tex]
5. So the answer is 7:6

Using circle theorems CD = 9.17
What are circle theorems?Circle theorems are theorems that govern circle properties.
Given that form the figure EF = 8, ON = 3 and OM = 2, we need to find CD.
From the figure using Pythagoras' theorem
OE² = ON² + EN²
= ON² + (EF/2)²
= 3² + (8/2)²
= 3² + 4²
= 9 + 16
= 25
OE = √25
= 5
Also, OD² = OM² + DM²
Making DM subject of the formula, we have that
DM² = OD² - OM²
DM = √(OD² - OM²)
Now OD = OE = 5
So, we have that
= √(OD² - OM²)
= √(OE² - OM²)
= √(5² - 2²)
= √(25 - 4)
= √(25 - 4)
= √21
= 4.58
Now CD = 2DM
= 2 × 4.58

Use the image to determine the type of transformation shown.
Horizontal translation
Vertical translation
Reflection across the x-axis
90° clockwise rotation
(Use Image added)
Answer:
Vertical translation
Step-by-step explanation:
Let's compare each point to its corresponding point in the image.
First, look at point A. Look at point A'.
With respect to the shapes ABCD and A'B'C'D', they are in the same position (in between B/B' and D/D'; across from C/C').
If you look at the image again, you'll find that the shape A'B'C'D' is not a rotated version of ABCD.
Thus, we can rule out the option "90° clockwise rotation."
A reflection across the x-axis indicates that A'B'C'D' and ABCD would be symmetrical across the x-axis (a horizontal line).
Because ABCD and A'B'C'D' are not symmetrical across a horizontal line, we can also rule out "Reflection across the x-axis."
Now, look at the position of A'B'C'D' with respect to ABCD. It's directly next to ABCD. In other words, it was shifted sideways.
Translations are basically just shifts.
Recall that horizontal means up and down, while vertical means side to side.
Since this is a sideways shift, we can conclude that the translation was:
a vertical translation.

The biggest effect of electing so many public officials is that it can be difficult for voters to make informed decisions.
With so many candidates to choose from, voters may not have the time or resources to thoroughly research each candidate and their qualifications. This can lead to uninformed voting, where voters may simply choose a candidate based on their name recognition, party affiliation, or other superficial factors.
Additionally, contested elections can also lead to an increase in negative campaigning and attack ads, which can further cloud voters' perceptions of the candidates and the issues at stake. Ultimately, electing a large number of public officials can make it harder for voters to feel confident in their choices and can undermine the democratic process.

Henry is saving up to buy a new jacket. He already has $95 and can save an additional $5 per week using money from his after school job. How much total money would Henry have after 10 weeks of saving? Also, write an expression that represents the amount of money Henry would have saved in w weeks
An expression that represents the amount of money Henry would have saved in w weeks is $95 + ($5 x w)
Henry already has $95, and he can save an additional $5 per week. So after one week of saving, Henry would have a total of $100 ($95 + $5). After two weeks, he would have $105 ($100 + $5), and so on.
To find out how much total money Henry would have after 10 weeks of saving, we can use the same method. After 10 weeks, Henry would have saved a total of $145 ($95 + ($5 x 10)). So, Henry would have a total of $145 after 10 weeks of saving.
Now, let's talk about an expression that represents the amount of money Henry would have saved in w weeks. We can use the formula:
Total amount saved = $95 + ($5 x w)
This formula takes into account the $95 that Henry already has, and the additional $5 he can save each week. The "w" in the formula represents the number of weeks Henry has been saving for. By plugging in different values of "w", we can determine how much money Henry would have saved at different points in time.

write 3.6*10^5+4.8*10^4 in scientific notation
Answer: 3.610^5+4.810^4 in scientific notation is 4.08*10^5.
Step-by-step explanation: The initial step to convert 3.610^5+4.810^4 into scientific notation is to combine the two values.
The sum of 3610 multiplied by 10 to the power of 5 and 4810 multiplied by 10 to the power of 4 is equal to adding 3610 multiplied by 10 to the power of 4 and 4810 multiplied by 10 to the power of 4, resulting in 40.8 multiplied by 10 to the power of 4.
We can convert 40.8*10^4 to scientific notation by shifting the decimal point to the left until there is only one non-zero digit to the left of the decimal, and denoting the number of decimal places moved with a 10 exponent.
Rewording: When you raise 40.810 to the power of 4, the result is 4.0810 to the power of 5 when you add 1 to the exponent. This is equivalent to multiplying 4.08 by 10 and raising it to the power of 5.

what value of c is such that 99% of all parcels are at least 1 lb under the surcharge weight? (round your answer to four decimal places.)
the value of c is 11.165 lbs. This was calculated using the z-score formula, assuming a normal distribution with a mean weight of 10 lbs and a standard deviation of 0.5 lbs. This ensures that 99% of all parcels are at least 1 lb under the surcharge weight.
To find the value of c, we need to use the standard normal distribution and the z-score formula. Since we know that 99% of all parcels are at least 1 lb under the surcharge weight, we can use the z-score associated with the 99th percentile, which is 2.33 (from a z-score table).
The formula for the z-score is:
z = (x - μ) / σ
where x is the weight of the parcel, μ is the mean weight, and σ is the standard deviation.
In this case, we want to find the weight of the parcel that is at the 99th percentile, which is 1 lb under the surcharge weight. Let's call this weight x. We know that the surcharge weight is c, so the weight of the parcel that is 1 lb under the surcharge weight is (c - 1).
Using the z-score formula and substituting the values we know, we get:
2.33 = ((c - 1) - μ) / σ
We want to solve for c, so we need to rearrange the equation:
c - 1 = 2.33σ + μ
c = 2.33σ + μ + 1
We don't know the values of μ and σ, but we can use the fact that the distribution is normal to estimate them. We can assume that the distribution is centered at the mean weight of all parcels, and that the standard deviation is equal to the average difference between the weight of each parcel and the mean weight.
Let's say that the mean weight is 10 lbs, and the standard deviation is 0.5 lbs. Then, we can plug these values into the equation for c:
c = 2.33(0.5) + 10 + 1
c = 11.165
So, the value of c that ensures that 99% of all parcels are at least 1 lb under the surcharge weight is approximately 11.165 lbs.

Bringing all the terms to one side, we get
x² - 7x + 12 = 0
Now we can factor the quadratic equation to get
(x - 3)(x - 4) = 0
So the solutions are x = 3 and x = 4. However, we need to check for any extraneous solutions that may have been introduced by the original equation.
Plugging in x = 3 to the original equation, we get
-2/(3 - 8) = (3 - 1)/(3 + 2)
Which simplifies to
2/5 = 2/5
Therefore, x = 3 is a valid solution.
Plugging in x = 4 to the original equation, we get
-2/(4 - 8) = (4 - 1)/(4 + 2)
Which simplifies to
1/2 = 3/6
Therefore, x = 4 is not a valid solution.
So the only solution to the equation is x = 3.

Find the exact value: tan 13pi/12
(Use the fact that 13pi/12 = 3pi/4 + pi/3
Thanks in advance!
Answer: the exact value of tan(13π/12) is √3 + 2.
Step-by-step explanation: The trigonometric equation demonstrating the equality between the tangent of 13π/12 and the tangent of 3π/4 added to π/3 may be expressed in the formal and technical tone often employed in academic writing as follows: tan(13π/12) = tan(3π/4 + π/3).
Through utilization of the identity, tan(a+b) = (tan(a) + tan(b)) / (1 - tan(a)*tan(b)), the given expression may be rendered more concise.
The trigonometric expression tan(13π/12) can be represented as (tan(3π/4) + tan(π/3)) divided by (1 - tan(3π/4) multiplied by tan(π/3)).
It is established that:
it can be observed that the value of the trigonometric function of tan(3π/4) is -1.
The mathematical expression "tan(π/3) = √3" signifies that the trigonometric tangent function of the angle π/3 is equivalent to the square root of three.
Upon substitution of the aforementioned values, the resulting output is obtained.
The trigonometric function of tan(13π/12) can be expressed as a quotient between two real numbers. Specifically, it can be represented in the form (-1 + √3) / (1 + (-1) * √3).
By utilizing the conjugate of the denominator and performing the operation of multiplication on both the numerator and denominator, the resulting expression is obtained:
The trigonometric function of tangent evaluated at 13π/12 is expressed as the product of two fractions. The numerator of the first fraction is comprised of the difference of the values -1 and the positive square root of 3, while the denominator is the sum of the value 1 and the product of -1 and the square root of 3. The numerator of the second fraction is the sum of the values 1 and the positive square root of 3, while the denominator is the sum of the same values.
The trigonometric identity expressed as tan(13π/12) has been rendered in symbolic form, wherein the numerator is the summation of -1, √3, √3, and -3. The denominator is the product of (1 + √3) and (1 - √3).
The mathematical expression tan(13π/12) can be represented as (-2√3 - 4) / (-2).
The mathematical expression tan(13π/12) is equivalent to the value of √3 + 2.
students conducted a survey and found out that 18% of their peers on campus go home every weekend but only 3% rides the public transportation. if 100 students were surveyed, can these students use the normal approximation to study the proportion of students in the population who go home every weekend?
To determine whether the normal approximation can be used to study the proportion of students in the population who go home every weekend, we need to check if the sample size is large enough and if the success-failure condition is met.
Sample size: A commonly used rule of thumb is that the sample size should be at least 10 times the number of successes and failures combined. In this case, the number of students who go home every weekend in the sample is 18, and the number who do not is 82. So the sample size is 100, which is greater than 10 times the number of successes and failures combined.
Success-failure condition: Another assumption for the normal approximation is that the sample proportion is not too close to 0 or 1. In this case, the sample proportion of students who go home every weekend is 18/100 = 0.18, and the proportion who do not is 0.82. Both proportions are between 0.1 and 0.9, so the success-failure condition is met.
Therefore, we can use the normal approximation to study the proportion of students in the population who go home every weekend.
