A pair of shoes cost $120 but they are 25% Off;
What would be discount and the final price of those
shoes?
Answer:
Discount = $30, Final price = $90
Step-by-step explanation:
25% is one quarter. 120/4=30
One quarter of 120 is 30, so - 30 would give discounted price of $90.
Similarly you could think of it like the discounted price is 75% of the original one and do 120x0.75=90 to find 75% of 120.

Answer:
In order from smallest to largest:
g(x)=(1,-2)
now, f(x) and h(x) would reach the same height, so from left to right on the graph, if plotting all vertices:
h(x)=(-2,2)
f(x)=(4,2)
Step-by-step explanation:
f(x)
f(x)=-2(x-4)^2+2
This is the vertex form of a quadratic equation: The formula used is f(x)=a(x-h)^2+k, where (h,k) is the vertex. In this case, 4 is h and 2 is k, so the vertex of this equation is (4,2).
g(x)
g(x)=5x^2-10x+7
To find the vertex of a quadratic equation in standard form, you first have to find the x-coordinate of the vertex using the formula, -b/2a. In this equation, a=5 and b=-10, so plug into the formula: -(-10)/2(5)=10/10=1, so the x-coordinate of the vertex is 1. Now to find the y-coordinate of the vertex by plugging in the x-coodinate for x in the equation: 5(1)^2-10(1)+7=5(1)-10+7=5-10+7=-5+7=-2, so your y-coordinate is -2. Therefore, your vertex for this equation is (1,-2).
h(x)
So, this quadratic function is in the form of a graph. The vertex of the graph is the maximum of minimum value of the graph, depending on whether the graph is positive or negative. In this graph, it is the maximum point, which is (-2,2).
If the figure above shows the graph of the function F, where f(x) = x^2 + 1, if the graph Gis the same as the reflection of about the x axis which of the following is g(x)?
Answer:
B, g(x)=-x^2-1
Step-by-step explanation:
-g(x)=x^2+1 is the reflection of g(x)=x^2+1 over the x-axis. Therefore, g(x)=-x^2-1.

y = 4800(1.239)
growth or decay
Hello there! :D
Well, it is a general rule of thumb that growth is indicated by positive numbers, and decay is indicated by negative numbers. I would show decay in this exponential equation by making the percentage inside the parenthesis negative. It would look like this: y=4800(-1.239)
Obviously, this equation does not have a negative integer so we know it must constitue growth!
I hope this helped you and that you have a wonderful day,

Find the approximate side length of a square game board with an area of 105in2.
Answer:
Approximately 10.2 inches
Step-by-step explanation:
The area of a square is given by the formula:
[tex]A=s^2[/tex]
Where A is the area and s is the side length.
Since we already know that the area A is 105, substitute:
[tex]105=s^2[/tex]
Now, take the square root of both sides:
[tex]s=\sqrt{105}[/tex]
Use a calculator:
[tex]s\approx10.2470[/tex]
So, the side length is approximately 10.2 inches.
Angie and kenny play online video games. Angie biys 1 software package and 4 months of game play. Kenny buys 1 software package and 1 month of game play. Each software costs $35. If their total cost is $130 what is thr cost of one month of game play
Answer:
1 month of game play will cost $12
Step-by-step explanation:
Here in this question, we are interested in calculating the cost of one month of game play.
From the question, we know the following;
Angie bought 1 software package and 4 months of game play
while
Kenny bought 1 software package and 1 month of game play.
The total packages and months bought will be;
2 packages and 5 months of game play
From the question, we are told that 1 month of game play is $35, so 2 months of game play will be 2 * $35 = $70
So the amount remaining for the 5 months will be; $130 - $70 = $60
So if 5 months cost $60, it means one month will be $60/5 = $12
A die is thrown . find the probability of (1) a multiple of 2 or 3
Answer:
A die is thrown which means that it can land on either 1-6 on the die.So if you want to find the probability of the multiple of 2 or 3....we have multiplies of 2 in the die from 1-6 which is 2,4 and 6 if you count them they are just 3 numbers and since there is a probability of it to land on any of them it will be 3/6 which is 1/2 if yiu divide by 3 to it's lowest term....Then multiple of 3 is 3,and 6.which will be 2/6 which is 1/3 if u cut to its lowest term. Or in the question means addition sign in probability then it is 2 or 3 which is (1/2)+(1/3)=5/6.Thank you for the question

Please answer area of this triangle
Answer:
[tex]A=2\text{ units}^2[/tex]
Step-by-step explanation:
The area for a triangle is given by:
[tex]A=\frac{1}{2}bh[/tex]
Where b is the base length and h is the height.
The base is 2 and height is also 2. Therefore:
[tex]A=\frac{1}{2}(2)(2)[/tex]
Simplify:
[tex]A=\frac{1}{2}(4)[/tex]
Multiply:
[tex]A=2\text{ units}^2[/tex]
The state of Kansas has a population of about 2.85 million people. Find the population density
in the people per square mile.
Answer:
In the state of Kansas, the density of people per square mile is 34.3
Step-by-step explanation:
According to US topographers, the state of Kansas has an area of 213 096 km².
If 1 km² is equal to 0.39 mi², then how much is 213 096 km².
If 1 km² : 0.39 mi².
213,096 km² : 83,107.44 mi²
If the state of Kansas has a population of 2.85 million people, then:
2.85 x10^6 people / 83 107.44 mi² =
34.3 people per square mile.

Mr Jones is 4 years older than his wife and 31 years older than his son. their ages add up to 82 years. if Mr Jones is x years old, find the value of x and the ages of his wife and son.
first person here gets the brainiest award thingy!
Answer:
39 Mr Jones
35 Mrs. Jones
8 Son
Step-by-step explanation:
x ----> Mr. Jones
x - 4 ----> His wife
x - 31 ---> His son
x + (x - 4) + (x - 31) = 82
3x - 35 = 82
3x = 82 + 35
3x = 117
x = 117/3
x = 39 Mr Jones
x - 4
39 - 4

A deli has a special one-day event to celebrate its anniversary. On the day of the event, every eighth customer receives a free drink. Every twenty-eighth customer receives a free sandwich. If 200 customers show up for the event, how many of the customers will receive both a free drink and a free sandwich?
Answer:
the number of common customers are 8 in number
Answer: The answer is just 3 people will get BOTH the free drink and free sandwich.
Step-by-step explanation:
Every 8th = 1 free drink
Every 28th = 1 free sandwich
200 costumers showed
Add 28 to 28 until you reach the closest to 200 so: 28,56,84,112,140,168,196
Then add 8 to 8 until 200, every number that match the 28th sequence is 1 costumer that receives 1 drink and 1 sandwich
The match numbers are 56,112,168

1. Point P is between points F and G. The distance between points F and P
is 1/4 of FG. What is the coordinate of point P?
Answer:
Point P is in between points F and G.
Now, here we do not have the actual locations of F and G, so i will answer this in a general way.
Suppose that F is located at 0 and G is located at some value A.
Then the distance FG = A - 0 = A.
Now, the distance between F and P is:
Distance = (1/4)*FG = A/4
Then the location of P is equal to the location of F plus A/4
P = 0 + A/4
Now, writing this in a more general way:
P = F + FG/4
