A ping pong ball (0.02 kg), bowling ball (25 kg), cotton ball (0.3 kg), wrecking ball (500 kg), and baseball (5 kg) are all moving with the same velocity. Which answer choice lists them from least kinetic energy to most kinetic energy?
A
Wrecking ball, bowling ball, baseball, ping pong ball, cotton ball
B
Cotton ball, baseball, ping pong ball, bowling ball, wrecking ball
C
Cotton ball, pin pong ball, baseball, bowling ball, wrecking ball
D
Ping pong ball, cotton ball, baseball, bowling ball, wrecking ball
Answer:
D) Ping pong ball, cotton ball, baseball, bowling ball, wrecking ball.
Step-by-step explanation:
If they are moving at the same time, the objects that have more mass have more kinetic energy.
the heaviest is the wrecking ball, and then the bowling ball, the baseball, the cotton ball, and the ping pong ball.
The only answer that follows this (in reverse) is D

7. An administrator surveys a random sample of 48 out of 900 middle school students. Using the
survey results, the administrator predicts that 225 students are in favor of the new dress code.
How many of the 48 students surveyed were in favor of the new dress code?
Answer:
12 students
Step-by-step explanation:
225 is 25% of 900 and 25% of 48 is 12.
The number of students is 12 that is surveyed were in favor of the new dress code the answer is 12.
What is the percentage?It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.
We have:
An administrator surveys a random sample of 48 out of 900 middle school students.
Using the survey results, the administrator predicts that 225 students are in favor of the new dress code.
The proportion of sample = 225/900
= 0.25
In percent sample:
= 0.25x100 %
= 25%
A number of students surveyed were in favor of the new dress code:
= 25% of 48
= (25x48)/100
= 1200/100
= 12
Thus, the number of students is 12 that is surveyed were in favor of the new dress code the answer is 12.

Answer:
12
Step-by-step explanation:
Okay, so on a grid, points Q and R are parallel to each other on the point 6, we just have to figure out how far apart they are, and to figure that out, we have to find the distance between 8 and -4 so:
8 - -4 = 8 + 4 = 12
So, the distance from point Q to point R is 12

Construct an isosceles triangle with the given base and the opposite angle to the base.
Answer:
Proof of Construction: The compass was used as a measuring tool to obtain (and copy) the length of the given segment. Since the given segment and the copy are the same length, the segments are congruent.
Note: You may also think of the length from A to B as being the radius of a circle with center at A. By copying the circle at A', the radii segments will be congruent.

PLS help I’ll give brainliest i’d be so grateful
Answer:
f the equation is in the form, ax + b = c, where x is the variable, you can solve the equation as before. First “undo” the addition and subtraction, and then “undo” the multiplication and division. Solve 3y + 2 = 11. Subtract 2 from both sides of the equation to get the term with the variable by itself.
Step-by-step explanation:
Answer:
The goal in solving an equation is to get the variable by itself on one side of the equation and a number on the other side of the equation. To isolate the variable, we must reverse the operations acting on the variable. We do this by performing the inverse of each operation on both sides of the equation.

Solve 4/9 plus x =7/9 x =
Answer:
x = 1/3
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
x + 4/9 = 7/9
Step 2: Subtract 4/9 from both sides.
x + 4/9 - 4/9 = 7/9 - 4/9
x = 1/3
Answer:
x = 1/3 (or) 3/9
Step-by-step explanation:
Now we have to,
→ Find the required value of x.
The equation is,
→ (4/9) + x = 7/9
Then the value of x will be,
→ (4/9) + x = 7/9
→ x = (7/9) - (4/9)
→ x = (7 - 4)/9
→ x = 3/9
→ [ x = 1/3 ]
Hence, the value of x is 1/3.

Of the two lights on Dexter Street, the probability of the lights being red is 20% for the first light and 30% for the second light. If a car is driving down Dexter Street, what is the probability that it does not get stopped at either light?
The probability that it does not get stopped at either light is 14/25.
We have given
Of the two lights on Dexter Street, the probability of the lights being red is 20% for the first light and 30% for the second light.
What is the formula for probability?
The probability of an event A is defined as the ratio of the number of favorable events that occurred in A /total number of events in a sample space
Red light for the first:
The Probability of the red light is 20 out of 100 so you would just find the difference which is 80%.
80/100
Red light for the second:
The Probability of the second red light is 30 out of 100 so you would just find the difference which is 70%.
70/100
The probability of not being stopped at either, multiply across and reduce.
[tex]80/100 * 70/100= 14/25[/tex]
Therefore, The probability that it does not get stopped at either light is 14/25.

Answer: The answer is 165
Step-by-step explanation:
Those who will visit the garden more than 3 times in the next month will be those who visit 4, 5, and 6 or more times.
Out of the 75 surveyed, the total number of those are:
= 9 + 12 + 3
= 24
That would give a percentage of:
= 24 / 75
= 32%
This means that the best estimate for those who will visit more than 3 times is 32%.
Out of the total number of 516, that is:

You now know a lot about all the angles formed from two straight lines that intersect. You know which angles are congruent and which angles are supplementary. Based on this information, you can find the angle measurements of all the angles even when you only know the measurement of one angle. In the figure below, angle 2 measures 145 degrees. What are the measurements of angles 1, 3 and 4? A angle 1 = 35 degrees, angle 3 = 145 degrees, angle 4 = 35 degrees B angle 1 = 30 degrees, angle 3 = 30 degrees, angle 4 = 160 degrees C angle 1 = 35 degrees, angle 3 = 35 degrees, angle 4 = 145 degrees D angle 1 = 135 degrees, angle 3 = 145 degrees, angle 4 = 35 degrees
Answer:
This is the correct way to set up the equation:
9x + 88 + 6x + 182 = 180
I'm going to move some things around so we can combine like terms. It now reads:
9x + 6x + 88 + 182 = 180
9x + 6x = 15x, so the equation now reads:
15x + 88 + 182 = 180
88 + 182 = 270, so the equation reads:
15x + 270 = 180
Subtract the 270 from both sides. 180 - 270 is -90:
15x = -90
Divide both sides by 15. -90 divided by 15 = -6:
x = -6
Now we can substitute -6 back into the separate equations.
9(-6) + 88 = ?
9 times -6 is -54. -54 + 88 = 34.
6(-6) + 182 = ?
6 times -6 = -36. -36 + 182 = 146
Now we can add 34 and 146 together.
34 + 146 = 180
