The total number of hours each student spends volunteering in their community is shown in the stem-and-leaf plot.
Which statement is supported by the data in the stem-and-leaf plot?
A.
The most common number of hours volunteered is 25.
B.
The number of students who volunteered more than 30 hours is greater than the number of students who volunteered fewer than 30 hours.
C.
The number of students who volunteered between 9 and 20 hours is greater than the number of students who volunteered more than 40 hours.
D.
The most common number of hours volunteered is 42.
Answers
Answer:
C
Step-by-step explanation:
The most common number of hours volunteered is 34, so the answer can't be A or D. 7 students volunteered more than 30 hours, while 12 students did less than 30 hours, which means B is incorrect. There are 3 students that volunteered more than 40 hours and 6 that volunteered between 9 and 20 hours, which means C is correct.

D. 1.5x+6=27
x+6=18
x=12
The tree will take 12 years to be 27 feet tall.
E. 27÷1.5=18
18-6=12
Answers
Answer:
Step-by-step explanation:
Answers are A and B.
Facts given are :
Current height = 6 ft
Growth per year = 1.5 ft
Final height = 27
Explanation for A:
Assume it takes 'x' number of years.
initial height + growth in 'x' years = Total height of the tree after 'x' years
6 + 1.5x = 27
1.5x = 27 -6 = 21
(1.5 can be written as 3/2) 3x/2 = 21
3x = 42
x = 14
hence, number of years = 14
Explanation for B:
After 'x' years,
Final height - initial height = Growth in 'x' years
27 - 6 = Growth in 'x' years
21=Growth in 'x' years = 1.5x
21= 3x/2
42=3x
14=x
hence, number of years = 14

A. Plot points that show the volume when r=1, r=2, r=3, and .r=4.
B. Show your reasoning.
Answers
To plot points that show the volume of a sphere for different values of the radius, we can use the formula for the volume of a sphere:
V = (4/3)πr^3
For different values of the radius, we can substitute those values into the formula and calculate the corresponding volume.
A. Plotting points for r = 1, 2, 3, and 4:
When r = 1, V = (4/3)π(1)^3 = (4/3)π ≈ 4.19
When r = 2, V = (4/3)π(2)^3 = (4/3)π(8) ≈ 33.51
When r = 3, V = (4/3)π(3)^3 = (4/3)π(27) ≈ 113.1
When r = 4, V = (4/3)π(4)^3 = (4/3)π(64) ≈ 268.1
We can plot these points on a graph with radius on the x-axis and volume on the y-axis:
B. Reasoning:
As we can see from the formula for the volume of a sphere, the volume increases rapidly as the radius increases. In fact, the volume increases with the cube of the radius, which means that a small increase in radius can result in a significant increase in volume. This is why we see such a rapid increase in volume as we increase the radius from 1 to 4.
The graph of the volume of a sphere versus its radius is a curve that starts at zero when the radius is zero (i.e., a point) and increases rapidly as the radius increases. It is a smooth, continuous curve that does not have any sharp turns or corners. This is because the formula for the volume of a sphere is a smooth, continuous function of the radius, with no sudden jumps or changes.
-3 (x- 4/5) ≤ 6 solve step by step
Answers
-3x + 12/5 ≤ 6
Next, we can subtract 12/5 from both sides of the inequality to isolate the variable term on the left side.
-3x ≤ 6 - 12/5
Simplifying the right side of the inequality:
-3x ≤ 30/5 - 12/5
-3x ≤ 18/5
Finally, we can divide both sides of the inequality by -3. Since we are dividing by a negative number, we need to reverse the direction of the inequality.
x ≥ -18/15
Simplifying:
x ≥ -6/5
Therefore, the solution for the inequality is x ≥ -6/5.
Distribute the -3:
-3x + 12/5 ≤ 6
Subtract 12/5 from both sides:
-3x ≤ 6 - 12/5
Find a common denominator:
-3x ≤ 30/5 - 12/5
-3x ≤ 18/5
Divide by -3, remembering to flip the inequality since we are dividing by a negative number:
x ≥ -18/15
Simplify:
x ≥ -6/5
Rita is painting the walls in the playrooms at the daycare center. She estimates that she will need 1/4 gallon of paint for each wall. How many walls can she paint with 5 gallons of paint?
Answers
Answer:
20 walls can be painted.
Step-by-step explanation:
Rita needs to use ¼ a gallon per wall. So, using 1 gallon would result in painting 4 walls.
5 gallons times 4 would be 20.
So, with five gallons, 20 walls can be painted.

Bjorn is making aush, and he does not have enough of all the ingredients. He decides to make 5/6 of a whole recipe, which means he uses 1 1/4 L of water.
How much water is in a whole recipe?
____?
Answers
Answer:
1[tex]\frac{1}{2}[/tex]
5/6 of the whole recipe = 1 1/4 L of water
1 whole recipe = (1 1/4 L of water) / (5/6)
To divide a fraction by another fraction, we can multiply by the reciprocal of the divisor. Therefore, we can simplify the above expression as follows:
1 whole recipe = (1 1/4 L of water) * (6/5)
Multiplying 1 1/4 L by 6/5, we get:
1 whole recipe = (5/4 L) * (6/5) = 30/20 L = 1 1/2 L
Therefore, a whole recipe of aush requires 1 1/2 L of water.
Answer: 1 1/2 L

Answers
Answer: 90° clockwise rotation
Step-by-step explanation:
The rules for rotation are below:
90° clockwise rotation = (x, y)→(y, -x)
270° clockwise rotation = (x, y)→(-y, x)
180° counterclockwise rotation = (x, y)→(-x, -y)
90° counterclockwise rotation = (x, y)→(-y, x)
Let's take point B. Point B's coordinates are (3, -2). Point B' is (-2,-3). -x would be -3, and y stays the same.
Therefore, the answer is 90° clockwise rotation.

Answer:
B
Step-by-step explanation: The box represents the middle 50% of the data, with the bottom and top of the box representing the first and third quartiles, respectively. The line inside the box represents the median.
The whiskers extend from the box to show the range of the data, excluding outliers. Outliers are typically shown as individual points outside the whiskers.
Based on this information, we can see that the box in the box plot represents the middle 50% of the data. Therefore, the answer is B. The box, from 44 to 52, includes about 50% of the data.
