Answer:
15%
Step-by-step explanation:
we call the original price 100% and to find the discount amount :
Multiply 100 by $476 then divide by $560
100 × $476 ÷ $560 = 85
$476 is 85% of the original price therefore the amount of discount as in percentage is 100 - 85 = 15%

Jasmine and Stephanie are selling pies for a school fundraiser. Customers can buy cherry pies
and blackberry pies. Jasmine sold 12 cherry pies and 4 blackberry pies for a total of $136.
Stephanie sold 8 cherry pies and 1 blackberry pie for a total of $64. What is the cost each of one
cherry pie and one blackberry pie?
Please send a picture showing steps.
Answer:
Cost of each cherry pie = $6
Cost of each blackberry pie = $16
Step-by-step explanation:
Let x be the cherry pies and y be the blackberry pie.
Solution:
From the above statement Jasmine sold 12 cherry pies and 4 blackberry pies for a total of $136.
So, we write the first equation as.
[tex]12x+4y = 136 ------(1)[/tex]
And Stephanie sold 8 cherry pies and 1 blackberry pie for a total of $64.
So, we write the second equation as.
[tex]8x+y = 64 --------(2)[/tex]
First we solve equation 2 for y.
[tex]y = 64-8x[/tex] ------------------------(3)
Substitute [tex]y = 64-8x[/tex] in equation 1.
[tex]12x+4(64-8x) = 136[/tex]
[tex]12x+256-32x=136[/tex]
[tex]12x-32x=136-256[/tex]
[tex]-20x=-120[/tex]
[tex]x=\frac{120}{20}[/tex]
x = 6
Substitute x = 6 in equation 3.
[tex]y = 64-8(6)[/tex]
[tex]y=64-48[/tex]
y = 16
Therefore, cost of each cherry pie = $6 and cost of each blackberry pie = $16
By solving the system of equations, it is determined that the cost of one cherry pie is $6 and the cost of one blackberry pie is $16. These findings are crucial for pricing strategies in the school fundraiser.
Explanation:To solve the system of equations for the cost of cherry and blackberry pies sold by Jasmine and Stephanie for a school fundraiser, we can set up two equations based on the given information:
Let's denote the cost of one cherry pie as c and the cost of one blackberry pie as b. Therefore, we can form the following equations based on the problem statement:
Using the method of substitution or elimination, we solve for c and b.
For simplicity, let's use elimination. To eliminate b, we can multiply the second equation by -4 and add to the first:
-32c - 4b = -256
12c + 4b = 136
Combining these, we get -20c = -120, thus c = $6. Substituting c = 6 into the second equation, 8*6 + b = 64, gives us b = $16.
In real-life terms, this means one cherry pie costs $6, and one blackberry pie costs $16, which would be important for pricing and accounting in the fundraiser.

The function f(x) = 2x + 210 represents the number of calories burned when exercising, where x is the number of hours spent exercising.
The function g(x) = 2x + 125 represents the calorie deficit that occurs when following a particular diet, where x is the number of hours spent exercising.
What is (f + g)(2)? Explain.
Hey there!
When we say (f + g)(2), we are adding both functions together and plugging in 2 for x.
Since f(x) is equal to 2x + 210 and g(x) is equal to 2x + 125, (f + g)(x) is equal to (2x + 210) + (2x + 125).
That can be simplified to 4x + 335.
So, (f + g)(x) = 4x + 335.
Let's plug 2 in for x and solve.
(f + g)(2) = 4(2) + 335
Multiply.
(f + g)(2) = 8 + 335
Add.
(f + g)(2) = 343
The x value is consistent for the values of both equations, in both x is defined as the number of hours spent exercising.
So, (f + g)(2), which is 343, is the amount of calories burned and the calorie deficit on a diet when 2 hours are spent exercising.

A square prism measuring 6 km along each
edge of the base and 5 km tall. Find area
Final answer:
The total surface area of a square prism with a base edge of 6 km and height of 5 km is 192 km².
Explanation:
The question is about finding the surface area of a square prism (also known as a rectangular prism where the base is a square). A square prism has six faces: two square bases and four rectangular sides. To find the total surface area, we calculate the area of each face and sum them up.
The formula for the area of a square is side × side. Since the base of the prism is a square with each side measuring 6 km, the area of one square base is:
Area of one square base = 6 km × 6 km = 36 km²Since there are two square bases:
Total area of two square bases = 36 km² × 2 = 72 km²The formula for the area of a rectangle is length × width. The four rectangular sides each have one dimension that is the height of the prism (5 km), and the other dimension is the length of a side of the base (6 km), so:
Area of one rectangular side = 5 km × 6 km = 30 km²There are four such sides:
Total area of four rectangular sides = 30 km² × 4 = 120 km²Adding the areas of the bases and the sides:
Total surface area of the prism = 72 km² + 120 km² = 192 km²What is the Value of x?

Step-by-step explanation: The diagram shows a triangle which is actually in fact, two triangles placed into each other. The first one is triangle APR (the larger one) while the second one is triangle CDR (the smaller one).
Also the diagram shows line AP as being parallel to line CD. That makes triangle APR similar to triangle CDR.
We can now determine the ratios of the similar sides
If triangle APR = triangle CDR, then
Line PD/DR = AC/CR or
PD/PR = AC/AR or
CD/RD = AP/RP
Therefore to calculate X, we use the ratio,
PD/DR = AC/CR

Last month, Jim and Debbie earned $7,200. Debbie earned $1,600 more than Jim earned. How much did they each earn? Call the amount that Jim earned j and the amount that Debbie earned d.
Step-by-step explanation:
Let Jim earned $ x
Therefore, Debbie earned = $(x + 1600)
According to the given information:
[tex]x + (x + 1600) = 7200 \\ \therefore \: 2x = 7200 - 1600 \\ \therefore \: 2x =5600 \\ \\ \therefore \: x = \frac{5600}{2} \\ \\ \therefore \: x =2800 \\ [/tex]
Thus, Jim`s earning = $2800
Debbie`s earning = 2800 + 1600 = $4400
Lets Jim earn $ x
Therefore, Debbie earned=$(x+1600)
calculate Debbie's earnings
According to the given information :
[tex]x+(x+1600)=7200\\$$\therefore 2 x=7200-1600\\$$\therefore 2 x=5600\\$$\therefore x=\frac{5600}{2}\\$$\therefore x=2800\\$[/tex]
thus, Jim's earnings =$2800
Debbie's earnings =2800+1600=$4400

IF M∠J = 82, M∠L = 57, AND M∠K = 41, list the sides of JLK in order from smallest to largest.
angle list: k,l,j:
sides are: LJ, KJ, KL
To find the sides of triangle JLK in order from smallest to largest, we need to compare the measures of the angles. The side opposite the largest angle is the longest side, so we can determine the order of the sides based on the angle measures.
Explanation:The triangle JLK has angles J, L, and K with measures 82, 57, and 41 degrees, respectively. To determine the sides of JLK in order from smallest to largest, we can use the fact that the side opposite the largest angle is the longest side. So, we need to identify the largest angle and its corresponding side.
Comparing the measures of the angles, we can see that M∠J is the largest angle. Therefore, the side opposite angle J, which is side JL, is the longest side. Next, we compare the measures of the remaining angles. M∠L is the next largest angle, so the side opposite angle L, which is side LK, is the second longest side. Finally, M∠K is the smallest angle, so the side opposite angle K, which is side JK, is the shortest side.
Therefore, the sides of triangle JLK in order from smallest to largest are JK, LK, JL.

Final answer:
Mark can travel 390 miles on 13 gallons of gas, as his car gets 30 miles per gallon and distance is calculated by multiplying fuel efficiency by the number of gallons.
Explanation:
To calculate the distance Mark can travel on 13 gallons of gas, we use the formula: Distance = Fuel Efficiency imes Number of Gallons.
Mark's car gets 30 miles per gallon. Thus, the distance he can cover on 13 gallons of gas is calculated by multiplying 30 miles/gallon by 13 gallons, which equals 390 miles.
This is a straightforward multiplication problem involving units of fuel efficiency (miles per gallon) and quantity of fuel (gallons).
The solution directly gives us the total number of miles Mark can travel on 13 gallons of gas.
Order the integers from least to greatest.

How do you get the number 24 with the numbers 2,6,4,1
Answer:
(2+6)*(4-1) = 24
(2-1)*(6*4) = 24
(2-1)*6*4 = 24
(2-1)*(4*6) = 24
(2-1)*4*6 = 24
(6+2)*(4-1) = 24
6*(2-1)*4 = 24
6*(2-1)*4 = 24
6/(2-1)*4 = 24
6/(2-1)*4 = 24
write the domain and range in interval notation.
Domain: [tex][-2,6][/tex]
Range: [tex][0,5][/tex]
Explanation:
Domain:
The domain of a function is the set of all possible values of the independent variable x. From the graph, we can see that the function has the set of all possible values from -2 to 6. Hence, the domain is from -2 to 6.
Thus, writing the domain in interval notation, we have,
[tex]-2\leq x\leq 6[/tex]
This also can be written as [tex][-2,6][/tex]
Hence, the domain is [tex][-2,6][/tex]
Range:
The Range of a function is set of all possible values of y obtained by substituting the values for x in the function. From the graph, we can see that the function has the set of all possible values from 0 to 5. Hence, the range is from 0 to 5.
Thus, writing the range in interval notation, we have,
[tex]0\leq y\leq 5[/tex]
This also can be written as [tex][0,5][/tex]
Hence, the range is [tex][0,5][/tex]
The domain and range in interval notation represent sets of possible values a function can take. For instance, for the function f(x) = 2x + 3 where x can be any real number, both the domain and range would be (-∞, ∞). Square brackets denote inclusive endpoints, while parentheses denote exclusive endpoints in interval notation.
Explanation:In mathematics, particularly in functions, the domain and range represent sets of possible input and output values respectively. When expressed in interval notation, domain and range convey a concise representation of these sets.
Let's illustrate with an example. If we have the function f(x) = 2x + 3, and x can be any real number, the domain in interval notation would be (-∞, ∞). As for the range, since the function can also output any real number, the range would also be (-∞, ∞).
To write the domain and range in interval notation, remember that square brackets [ ] represent inclusive endpoints, while parentheses ( ) represent exclusive endpoints. The symbol '∞' is always cloaked by parentheses.
