Answer:
6/31
Step-by-step explanation:
4 1/3 divided by 5 1/6
Change the mixed numbers to improper fractions
4 1/3 = (3*4+1)/3 =13/3
5 1/6 = (6*5+1)/6 =31/6
13/3 ÷ 31/6
Copy dot flip
13/3 * 6/31
13*2/31
26/31
The question is asking what fraction should we end up multiplying by(the flip fraction)
That is 6/31
Answer:
The Answer is A) 6/31
Step-by-step explanation:
Describe two ways to express the edge length of a cube with a volume of 64
The edge length of a cube with a volume of 64 cubic units can be expressed as 4 units, which is the cube root of 64, or algebraically as V⅛ or 64⅛.
Explanation:To express the edge length of a cube with a volume of 64 cubic units, we can use the formula for the volume of a cube, which is V = L³, where V is volume and L is the length of an edge. Since we have the volume (V), we can solve for L (the edge length) by taking the cube root of the volume. Consequently, the cube root of 64 is 4, so one way to express the edge length is simply as 4 units.
Alternatively, we can express the edge length in terms of the formula for volume. If the volume V is a constant 64 cubic units, the edge length can be represented as V⅛, or 64⅛ in this specific case. This second expression emphasizes the relationship between volume and edge length in a cube and is particularly useful in algebraic and geometric applications.

A bee with velocity vector
r'(t)
starts out at
(5, −5, −3)
at
t = 0
and flies around for 5 seconds. Where is the bee located at time
t = 5
if
5
0
r'(u)du = 0?
Final answer:
The bee returns to the starting point at (5, -5, -3) after 5 seconds since the integral of its velocity over that period is zero, indicating no net change in position.
Explanation:
To find where the bee is located at time t = 5, we start by looking at the given velocity vector r'(t). Since ∫05r'(u)du = 0, this implies that the integral of the velocity function over the interval from 0 to 5 seconds results in zero net displacement. Thus, the total change in position of the bee over these 5 seconds is zero.
Since the bee starts at the position (5, −5, −3) at t = 0, and there is no net change in position over 5 seconds, the bee must return to the starting point at t = 5. Therefore, the bee is located at (5, −5, −3) at time t = 5 seconds.
The movie theater in town has 4 rooms. Each room has 58 seats on the left side and 32 seats on the right side. Which equation could be used to show the total number of seats in the theater?
A) 52 + 32= ?
B) 4 + 32 + 58= ?
C) (58 + 32) x 4= ?
D) (58 - 32) x 4= ?
Answer:
The right option is (C) (58 + 32)×4
Step-by-step explanation:
Total number of rooms = 4
Number of seats on left = 58 seats in each room
Number of seats on right = 32 seats in each room
Total number of seats in a room = 58 + 32 seats
Total number of seats in the movie theater = Number of rooms × Number of seats in each room
Total number of seats in the movie theater = 4 × (58 + 32) = 360 seats
Hence the right option is (C) (58 + 32)×4

A community center has an l shaped swimming pool that is 10 feet deep. What is the volume of the pool?
A. 640 cubic feet
B. 880 cubic feet
C. 1200 cubic feet
D. 1040 cubic feet
Answer:
1,040 cubic feet
Step-by-step explanation:
volume = width * length * height
In order to find this split the pool into two separate rectangular prisms.
The first one's measurements are 4ftx16ftx10ft
4*16*10 = 640
the next prism is 4ftx10ftx10ft
4*10*10 = 400
640+400= 1040 cubic feet

X is less than or equal to -8 graphed on a number line
Graphing x \<= -8 involves placing a solid circle at -8 on a number line and shading everything to the left to represent all numbers less than or equal to -8.
To graph x \<= -8 on a number line, you need to include every number that is less than or equal to -8. Start with a number line and locate the point -8 on it. Then, draw a solid circle at -8 to indicate that -8 is included in the solution (because of the '<=' symbol). Next, shade or draw a thick line to the left of -8, going towards the negative direction, to cover all numbers that are less than -8. This shaded area represents all the possible values for x that satisfy the inequality x \<= -8.
Visual Representation on Number Line
A visual representation helps to understand the solutions to the inequality. When graphing, remember that the area to the left of the chosen point on a number line includes all numbers less than the indicated value, and if the circle is solid, that point is also part of the solution set.
The process described here provides a straightforward approach to graphing linear inequalities on a number line, which is a fundamental concept in algebra.
In a distribution, a score of X=60 has a z-score of -3.0.. A score of X=85 has a z-score of 2.0. What are the mean and standard deviation for this population?
Final answer:
By using the z-score formula and solving a system of linear equations, we find that the mean (μ) of the population is 75, and the standard deviation (σ) is 5.
Explanation:
To find the mean (μ) and standard deviation (σ) of the distribution based on the given z-scores, we can use the z-score formula:
z = (X - μ) / σ. Rearranging this formula, we can express X as X = zσ + μ.
For the two provided z-scores and X values:
For X = 60 and z = -3.0: 60 = (-3)σ + μ
For X = 85 and z = 2.0: 85 = (2)σ + μ
We now have a system of linear equations that can be solved to find μ and σ:
-3σ + μ = 60
2σ + μ = 85
Solving for σ and μ:
Multiplying the first equation by 2, and the second equation by 3 and adding them gives us:
(-3)(2)σ + 2μ = 120
(2)(3)σ + 3μ = 255
Adding these together yields 5μ = 375, so μ = 75.
Now, substitute the μ value into either equation to find σ:
-3σ + 75 = 60
σ = (75 - 60) / 3
σ = 5
Therefore, the mean (μ) of the population is 75 and the standard deviation (σ) is 5.
A news reporter wants to estimate the percentage of registered voters who will vote for a particular candidate in an upcoming election. Which statement describes a method that will help him accurately estimate this percentage?
A.) He could contact every resident in the town, ask whether the resident will vote for the particular candidate, and then calculate the percentage of residents who say they will vote for the particular candidate.
B.)He could ask employees at the newspaper which candidate each will vote for, and then calculate the percentage who will vote for the particular candidate.
C.)He could take a random sample of registered voters, and then calculate the percentage of the sample who will vote for the particular candidate.
D.)He could ask his readers to respond to a survey that asks which candidate the reader will vote for and then calculate the percentage of people who say that they will vote for the particular candidate.
A news reporter wants to estimate the percentage of registered voters who will vote for a particular candidate in an upcoming election. Which statement describes a method that will help him accurately estimate this percentage?
Answer: In order to estimate the percentage of registered voters who will vote for a particular candidate in an upcoming election, a news reporter can randomly take a sample from the registered list of voters and based on their opinion a reporter can accurately estimate percentage of registered voters who will vote for a particular candidate in an upcoming election. Therefore, the option C will be correct.
Therefore the correct method is C) He could take a random sample of registered voters, and then calculate the percentage of the sample who will vote for the particular candidate.
The other options to gather the opinion about the percentage of the sample who will vote for the particular candidate are non probabilistic and there is every possibility of introduction of bias in the estimate. The only option which is probabilistic is option c because it involves random selection of respondents. Therefore the appropriate option is c.

A prism with a volume of 270 m³ is dilated by a factor of 3. What is the volume of the dilated prism? Enter your answer in the box.
A prism with a volume of 270 m³ is dilated by a factor of 3. What is the volume of the dilated prism? Enter your answer in the box.
If we dilate each dimension by 3, then the volume of the figure will be dilated by [tex] 3^{3} [/tex] .
[tex] 3^{3} [/tex] =3*3*3 =27
So, the volume of the dilated prism is [tex] 3^{3} [/tex] *volume of original prism
Volume of dilated prism=27*270[tex] m^{3} [/tex]
Volume of dilated prism=7290[tex] m^{3} [/tex]
The volume of a prism when dilated by a factor of 3 increases to 7290 m³,
A prism with a volume of 270 m³ that is dilated by a factor of 3 will have its new volume calculated by cubing the scale factor and multiplying it by the original volume.
Original Volume (V1) = 270 m³
Scale Factor (k) = 3
Dilated Volume (V2) = V1 × k³
So, V2 = 270 m³ × 3³
V2 = 270 m³ × 27
V2 = 7290 m³
Hence, the volume of the dilated prism is 7290 m³.
