The price of a video game was reduced from 60$ to $45. By what percentage was the price of the video game reduced?
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%.

The equation of sets is given by n(A∪B) = n(A) + n(B) - n(A⋂B)
What is Set Theory Formula?
The set formula is given in general as n(A∪B) = n(A) + n(B) - n(A⋂B), where A and B are two sets and n(A∪B) shows the number of elements present in either A or B and n(A⋂B) shows the number of elements present in both A and B.
Given data ,
Let the equation be represented as A
The value of A is
n(A∪B) = n(A) + n(B) - n(A⋂B)
So , from the given Venn diagram , we get
The number of people who have been to the United States and Australia is given by A = 2
The number of people who have been to Australia and not been to United States is B = 5
The number of people who have not been to Australia but been to United States is C = 6
The number of people who have not been to Australia and not been to United States is D = 4
Hence , the equation is solved by sets

Joe has dimes and nickels in his piggy bank totaling $1.45. The number of nickels he has is 5 more than twice the number of dimes, d. Write an equation that can be used to find the numbers of dimes, d, Joe has.
The number of dimes Joe has is 6.
Joe has dimes and nickels, the total amount is $1.45
We have to find the number of dimes Joe has.
Suppose the number of dimes is d, so we have the number of nickels is 2d + 5
Now from the question, we get an equation:
0.10d + 0.05( 2d+ 5) = $1.45
To know the value of d we need to solve the equation:
0.10d + 0.10d + 0.25 = 1.45
0.20d = 1.20
d = 120/20
= 6
Hence we get the total number of dimes Joe has is 6.

Jamie went to the movies with her twin sister, Jenna. They bought one large soda for $4.95 and 3 boxes of candy. Each box of candy cost the same amount. They spent a total of $18.45. Select the equation that best represents how you would solve for c, the cost of each box of candy?
Answer:
The Equation we can use to solve for the cost of each box of candy =
4.95 + 3b = 18.45
The cost of each box of candy = $4.5
Step-by-step explanation:
Let the number of boxes of candy be represented by: b
Each box of candy cost the same amount
Hence from the question above, we have the Equation:
$4.95 + 3b = $18.45
4.95 + 3b = 18.45
3b = 18.45 - 4.95
3b = 13.5
b = 13.5/3
b = 4.5
The cost of each box of candy = $4.5

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.
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.

please help me find the slope of the graph thank you a, b, c, d (picture)
Answer:
D: -75 the balloon is descending at a rate of 75ft per minute
Step-by-step explanation:
To find the slope of any graph, take two points on the graph and subtract them y/x so to get this answer is used the points (0,450) and (2,300) and subtracted the y-values over the x-values
450-300=150
0-2=-2
150/-2 = -75
that is the slope and since it is negative and the slope itself is a diagonal line going towards the x-axis you know it’s descending.

What is the most reasonable domain for this situation? Explain your answer.
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

To work out 20 - 5(3) you would multiply 5 and 3 first and then add the 20
to get a value of 35. Can you start at 35 and reverse those two steps to get
back to 32 Explain the two steps you would take to do that.
Answer:
You would get 5.
Step-by-step explanation:
According to the order of operations ( GEMDAS or PEMDAS ), in a problem the first step is grouping.
20 - 5(3) = 20 - 15, because 5 * 3 is 15 and parenthesis is a sign of multiplication. Then you would get:
20 - 15 = 5.
Here we would not inverse the subtraction sign, because there is an operation before the grouping
Would reverse operation:
20 - ( 5 + 3 )
Would NOT reverse operation:
20 - 5(2) Operation before the subtraction

Answer:
= 4 1/6 ---------------> final answer
Step-by-step explanation:
1 2/3 cup of sugar
That is : 5/3 cups of sugar for 1 cookie recipe
So for 1 recipe ------------- 5/3 cups of sugar
hence for 2 1/2 recipe ---------------> (5/3) * (5/2)
= 25/6
= 4 1/6 ---------------> final answer
Answer:
Step-by-step explanation:
1 2/3(3×1+2=5) × 2 1/2(2×2+1=5)

Bus A and Bus B leave the bus depot at 5 pm. Bus A takes 30 minutes to complete its route once and bus B takes 35 minutes to complete its route once. If both buses continue to repeat their route, at what time will they be back at the bus depot together?
Answer:
8:30 pm
Step-by-step explanation:
Bus A and Bus B leave the bus depot at 5 pm. Bus A takes 30 minutes to complete its route once and bus B takes 35 minutes to complete its route once. If both buses continue to repeat their route, at what time will they be back at the bus depot together?
We solve the above question using the Lowest Common Multiple Method.
We find the Multiples of 30 minutes and 35 minutes
Multiples of 30:
30, 60, 90, 120, 150, 180, 210, 240, 270
Multiples of 35:
35, 70, 105, 140, 175, 210, 245, 280
Therefore,
LCM(30, 35) = 210
The Lowest Common Multiple = 210. This means that bus A and bus B will be back at the same depot together after 210 minutes.
We add 210 minutes to 5pm
5 pm + 210 minutes
= 5 pm + 3 hours 30 minutes
= 8:30 pm
Bus A and Bus B will be back at the depot together by 8:30 pm.
