The price of a video game was reduced from 60$ to $45. By what percentage was the price of the video game reduced?
Answers
Answer:
the price was reduced by 25%
Step-by-step explanation:
60 - 45 = 15
15 is what percent of 60?
15/60 = .25 x 100 = 25%
also can notice that 15 is 1/4 of 60, so it is equal to 25%.
You would do 60 x 25 = 1,500
Remove the two zeros which would be 15
60 - 15 = 45
The height of a cylinder is 6 centimeters. The circumference of the base of the cylinder is 14 centimeters. Which measurement is closest to the volume of the cylinder in cubic centimeters.
Answers
The volume of the cylinder in cubic centimeters is 251.2 cm^3.
The volume of a cylinder is expressed as:
V = πr²h
V = base area * height
Given the following
Base area = 16π centimeters
Height = 5cm
Substitute into the formula to have:
V = 16(3.14) * 5
V = 251.2 cm^3
Hence the volume of the cylinder in cubic centimeters is 251.2 cm^3.

A 150 -inch pipe is cut into two pieces. One piece is two times the length of the other. Find the length of the shorter piece.
Answers
Answer:
im trying to get 50 points
Step-by-step explanation:
Answer:
The pipe lengths are 50 inches and 100 inches.
Step-by-step explanation:
If we refer to the length of the shorter piece as x, then we can say the length of the larger piece is 2x. We are also told that the pipe length is 150 inches, so we can say:
x + 2x = 150
3x = 150
x = 150/3
x = 50
So the pipe lengths are 50 and 100 inches respectively.

What is the most reasonable domain for this situation? Explain your answer.
Answers
Answer:
I don't know the answer but try using 900gle lens and scanning it on homework setting
Answer:
Range is 0 ≤ h ≤ 32
Step-by-step explanation:
The height is a function of time and is described as h(t) = -8t² + 32t
h is the y-axis and t is the x axis, so we can write this as y = -8x² + 32 x.
This describes a parabola that opens downward, since the coefficient of the square term is negative. The maximum point for height will be at the vertex of the parabola.
y = ax² + bx + c
The x coordinate of the vertex is at -b/2a
a = -8, b = 32, c = 0
-b/2a = -32/-16 = 2
Maximum height is at x = 2 seconds (we can see this on the graph)
At 2 seconds, y = -8(2²) + 32(2) = -32 + 64 = 32
Again, we can see this on the graph.
The x intercepts are the points where y = 0
0 = -8x² + 32x = 8x(-x +4)
y will be 0 when x is 0 or 4 (confirmed by graph)
So, the height (y) = 0 at time (x) = 0 sec, 4 sec
0 ≤ y ≤ 32
y = h, so 0 ≤ h ≤ 32
I hope this helps.

Fill in the inequalities below to specify the graph's domain shown. Domain: __ is not greater than or equal to x, which is below 4.
Fill in the inequalities below to specify the graph's range shown.
Range: __ is not greater than or equal to y, which is below 5.
The domain and range is the graph's domain is its set of potential input values, and its range is its set of potential output values.
Following is the finished inequality reflecting the set of the domain and range;
First,
Domain: -4 is below x, which is below or equal to 4.
Second,
Range: -2 is below y, which is below or equal to 5
The attached graph shows that the point (-4, 5) has an open circle, which denotes that the point has no value.
The closed circle at the other end of the graph, at the coordinates (4, -2), denotes that the graph has a value at that location (4, -2)
First,
The domain of a graph is the set of potential inputs (x-values) for the graph, expressed as inequality is -4 < x ≤ 4
Therefore;
To complete the inequality for the domain, gives;
Domain: -4 is less than x which is less than or equal to 4
Second,
The range of a graph are the possible output (y-values) of the graph, in inequality notation, the domain of the attached graph is -2 ≤ y < 5
the domain supplies the necessary inequality to be complete;
Range: -2 is less than or equal to y which is less than 5.
