lmk if its right bc im not too confident </33
D. The new volume will be 8 times the original volume.
The measurements of the rectangular prism are 5m ( length ), 3m ( width ), and 2m ( height ). To find the volume of the rectangular prism, you have to multiply the length, width, and height altogether. That gives you ( 5*3*2= ) 30 cubic meters. However, if the measurements were doubled for each edge, the new measurements would be ( 5*2= ) 10m ( new length ), ( 3*2= ) 6m ( new width ), and ( 2*2= ) 4m ( new height ). Multiplying those new measurements together would get you the volume of ( 10*6*4= ) 240 cubic meters. Now, in order to find out how it affects the volume of the prism, you divide 240 cubic meters by 30 cubic meters and get 8. Therefore, the answer will be D. The new volume will be 8 times the original volume.

At a certain middle school, there are 200 5th graders, 220 6th graders, 180 7th graders, and 150 8th graders. The Dean of Students chooses a scholar at random to help run Community Circle. What is the probability that a 7th grader is chosen?
Answers
Answer:
6/25
Step-by-step explanation:
Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.
For example, the probability that it would rain on Friday is between o and 1. If it rains, a value of one ids attached to the event. If it doesn't a value of zero is attached to the event.
probability that a 7th grader is chosen = total number of 7th graders / total number of students
total number of 7th graders = 180
total number of students = 200 + 220 + 180 + 150 = 750
180 / 750
To transform to the simplest form. divide both the numerator and the denominator by 30

Use the rectangle FOUR to find the value of x.
in FU = 38, RQ = 2x + 9.
Answers
Answer:
x = 5
Explanation:
2x + 9 = 19
2x = 10
x = 5
Applying the properties of the diagonal of a rectangle, the value of x is determined as: 5.
Diagonals of a RectangleThe diagonals of a rectangle are of equal length.The diagonals of a rectangle bisects each other into two equal halves.FU and RO are diagonals of rectangle FOUR.Therefore:
2(RQ) = FU
Substitute
2(2x + 9) = 38
4x + 18 = 38
4x = 38 - 18
4x = 20
x = 5
Thus, applying the properties of the diagonal of a rectangle, the value of x is determined as: 5.

Aretha's teacher will choose two students from a class of 10 to prepare a display. Assuming the teacher chooses these students at random,
what is the probability that Aretha will not be chosen?
Answers
Answer:
80% chance she will not be chosen
Step-by-step explanation:
the ratio of students picked would be 2:10 so there would be 8:10 students not chosen that is 80%. 20% chance she would be chosen.
I hope this is correct!
The probability that Aretha will not be chosen is 0.8.
What is the probability?Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event.
Given that, Aretha's teacher will choose two students from a class of 10 to prepare a display.
We know that, probability of an event = Number of favourable outcomes/Total number of outcomes
Probability of choosing 2students =2/10
Probability of not choosing students = 1-2/10
= 8/10
= 0.8
Therefore, the probability that Aretha will not be chosen is 0.8.

Fred purchased a cone filled with cinnamon pieces. The cone is 7 inches tall and has a diameter of 2. How many cubic inches does the cone hold? Leave your answer in terms of pi
Answers
Answer:
V = 9.33 π m³
Step-by-step explanation:
Given: The cone is 7 inches tall and has a diameter of 2
To find: How many cubic inches the cone can hold
Formula: The formula for the volume of a cone is V = [tex]\frac{1}{3} h\pi r[/tex]².
Solution: A cone is a solid that has a circular base and a single vertex. To calculate its volume you need to multiply the base area
(area of a circle: π × r²) by height and by [tex]\frac{1}{3}[/tex]:
volume = ([tex]\frac{1}{3}[/tex]) × π × r² × h.
In terms of pi V = 9.33 π m³
