Answer:
No. You would have to cut the number of veggie burgers in more than half.
Explanation:
1. Model the situation with a system of equations
a) Name the variables:
number of turkey burgers: tnumber of veggie burgers: vb) Number of burgers:
50 = t + vc) Cost of the 50 burgers:
$90 = 2t + 1.50v2. Solve that system of equations:
a) System
50 = t + v90 = 2t + 1.50vb) Mutliply the first equation by 2 and subtract the second equation
100 = 2t + 2v 90 = 2t + 1.50v10 = 0.5vv = 20 ⇒ t = 50 - 20 = 30c) How much would you spend if the next year you buy the double of 20 turkey burgers (40) and the half of 30 veggie burgers (15)
$2(40) + $1.50(15) = $80 + $22.50 = $102.50Then, you if you double the number of turkey burgers, and cut the number burgers in half, you would spend more than $90 ($102.50).
Points A, B, and C are midpoints of the sides of right
triangle DEF
Which statements are true? Select three options. (The
formula for the area of a triangle is A = bh.)
BC = 6 cm
AC = 5 cm
BA = 4 cm
DE = 10 cm
FD = 6 cm
FE = 8 cm
The perimeter of triangle ABC = 12 cm.
The area of triangle ABC is
the area of triangle DEF.
The correct statements of the triangle are; AC = 5 cm; BA = 4 cm; The perimeter of triangle ABC is 12 cm.
What are the correct statements of the Triangles?As we know that a, b, and c are midpoints of the sides of right triangle that means midpoint divide the side in equal parts.
Now we have to calculate the sides of triangle ABC by using Pythagoras theorem.
Using Pythagoras theorem in ΔACF :
AC² = FA² + CF²
Thus;
AC² = 3² + 4²
AC = √25
AC = 5
Using Pythagoras theorem in ΔDAB, we have;
BA = √(5² - 3²)
BA = 4 cm
Using Pythagoras Theorem, we have;
CB = √(5² - 4²)
CB = 3 cm
Perimeter of ΔABC = Side AB + Side CB+ Side AC
Perimeter of ΔABC = 4 + 3 + 5
Perimeter of ΔABC = 12 cm
Area of ΔABC = (1/2) * 4 * 3 = 6 cm²
Area of ΔDEF = (1/2) * 8 * 6 = 24 cm²
Area of ΔABC = (6/24) * Area of ΔDEF
Area of ΔABC = (1/4) * Area of ΔDEF

Given the information provided, we can determine the lengths of the sides of triangle ABC and its perimeter and area.
Explanation:Given that points A, B, and C are midpoints of the sides of right triangle DEF, we can determine the lengths of the sides using the information provided.
BC = 6 cmAC = 5 cmBA = 4 cmDE = 10 cmFD = 6 cmFE = 8 cmTo find the perimeter of triangle ABC, we sum the lengths of all three sides: AB + BC + CA. Substituting the given lengths, AB = BA = 4 cm, BC = 6 cm, and CA = AC = 5 cm, the perimeter is 4 cm + 6 cm + 5 cm = 15 cm.
The area of triangle ABC can be determined using the formula A = bh, where b is the base and h is the height. Triangle ABC and triangle DEF are similar triangles, so their areas are proportional. Since point A is the midpoint of DE, half the base of triangle DEF is equal to the base of triangle ABC. Substituting the given length of DE = 10 cm, the base of triangle ABC is 10 cm / 2 = 5 cm. The height of triangle ABC is equal to the length of AC = 5 cm. Therefore, the area of triangle ABC is A = 5 cm * 5 cm = 25 cm².

5. Graph the given relation or equation and find the domain and range. Then determine whether the relation or equation is a function.
(3.9, 5.9), (–1.1, 5.9), (–4.1, 3.9), (–4.1, –2.1)
Given:
Given that the coordinates are (3.9, 5.9), (–1.1, 5.9), (–4.1, 3.9), (–4.1, –2.1)
We need to determine domain and range and also find whether the relation is a function.
Domain:
The domain is the set of all independent x - values.
Thus, we have;
[tex]Domain=\{3.9,-1.1,-4.1\}[/tex]
Thus, the domain is {3.9,-1.1,-4.1}
Range:
The range is the set of all dependent y - values.
Thus, we have;
[tex]Range=\{5.9,3.9,-2.1\}[/tex]
Thus, the range is {5.9,3.9,-2.1}
Function:
We need to determine whether the given relation is a function.
For a relation is said to be a function, if every value of x has only one image in the y - coordinate.
After plotting the graph, it is obvious that the x - value -4.1 has two images 3.9 and 2.1
Hence, the given relation is not a function.

Step-by-step explanation:
Wilson is 6 years older than Mary. Wilson's age is 10 years less than five times Mary's age. The equations below model the relationship between Wilson's age (w) and Mary's age (m):
w = m + 6
w = 5m - 10
Which is a possible correct method to find Wilson's and Mary's ages?
Solve W + 6 = 5w - 10 to find the value of w.
Write the points where the graphs of the equations intersect the x axis.
Solve m + 6 = 5m - 10 to find the value of m.
Write the points where the graphs of the equations intersect the y axis.
Final answer:
The correct method to find Wilson's and Mary's ages with the given equations is to solve the equation m + 6 = 5m - 10 by substitution, which will give you the value of Mary's age (m). After finding m, you can then solve for Wilson's age (w).
Explanation:
Among the provided methods to find Wilson's and Mary's ages based on the given equations w = m + 6 and w = 5m - 10, the correct approach is to solve m + 6 = 5m - 10 to find the value of m, Mary's age. This is due to the fact that by substituting the expression for w from the first equation into the second, we isolate m and solve for it directly. Here is how you'd solve it step by step:
First, substitute w from the first equation into the second equation, resulting in m + 6 = 5m - 10.
Next, rearrange the terms to get all the m terms on one side: 5m - m = 10 + 6.
Then, simplify to find that 4m = 16.
Last, divide both sides by 4 to get m = 4.
Once you have m, substitute it back into either of the original equations to find w. In this case, w = 4 + 6 = 10.
Graphical solutions involving the x or y axis do not apply directly to solving the system of equations and are therefore not correct methods for this particular problem.
There are 18 offensive players on the hockey team. How many ways can the coach choose a left wing, center, and right wing to start the game?
Answer:
4896 ways
Step-by-step explanation:
We have a total of 18 players, and we want to form groups of three, where the order matters, because there are different roles for each player, so this is a permutation problem.
We solve this problem calculating a permutation of 18 choose 3:
P(18,3) = 18! / (18-3)! = 18! / 15! = 18 * 17 * 16 = 4896
So the coach has 4896 ways to choose the left wing, center and right wing.
Answer: There are 4,896 possible ways
Step-by-step explanation: If there are 18 offensive players on the hockey team, and there is a need to make a selection of three players for three different positions, that means each time you choose one player there is an 18 times 17 (18 x 17) other possibilities for the remaining players. If you choose the next player, there would now be a 17 times 16 (17 x 16) other possibilities for the remaining players, hence we need a formula for the arrangement of 3 players to be chosen from a total of 18.
From the first explanation, if we were to make an arrangement to choose all 18 players the permutation would be given as;
P = 18! (18 factorial)
Which is 18 x 17 x 16 x 15 x 14 x... x 1
However the permutation for selecting just 3 out of the 18 players is given as;
P = 18! ÷ 15!
And this results in;
P = 18 x 17 x 16
P= 4896
Therefore there are 4,896 possible ways
**Note that 18! divided by 15! leaves you with the possible arrangement for 3 persons which is explained as 18 x 17 x 16**
Twice one number added to another
number is 18. If the second number is equal
to 12 less than 4 times the first number, find
the two numbers.
First complete the equations below, where x stands for
the first number and y stands for the second number.
2x + y = 18; y = [?]x-[]
Answer:
The Answer is: The first number is 5 and the second one is 8.
please give me brainliest!! :)
Step-by-step explanation:
Let f = first number and s = second number
Twice the first number added to the second number is 18:
2f + s = 18
The second number is equal to 4 times the first number minus 12:
s = 4f - 12
Substitute:
2f + (4f - 12) = 18
6f - 12 = 18
6f = 18 + 12
6f = 30
f = 5, is the first number.
Solve for the 2nd number:
s = 4(5) - 12 = 20 - 12 = 8, is the second number.
Proof:
2f + s = 18
2(5) + 8 = 18
18 = 18
Hope this helps! Have an Awesome Day! :-)
Answer:
y = 8
x = 5
Step-by-step explanation:
This is a system of equations problem
Set up your two conditions:
2x + y = 18
y = 4x - 12
rearrange them to match
y = -2x + 18
y = 4x - 12
combine them by subtracting one equation from the other in such a way that it eliminates one variable. In this case I choose to subtract each value from the second equation from the first one
0 = -6x + 30
solve
6x = 30
x = 5
plug in the x value to solve for y
2(5) + y = 18
10 + y = 18
y = 8

Factor as the product of two binomials.
X^2 – 10x + 21
The requried expression of the given expression which is a product of two binomials is (x - 3)(x - 7).
What is a polynomial function?A polynomial function is a function that applies only integer dominions or only positive integer powers of a value in an equation such as the monomial, binomial, and trinomial, etc. ax+b is a polynomial.
Here,
Given expression,
x² - 10x + 21 = 0
In order to factor the above expression in two binomial expressions, split the 10x in two where the multiplication of two numbers produces 21 and their difference produces -10x,
So,
y = x² -7x -3x + 21
y= x(x - 7) - 3 (x - 7)
y = (x - 3)(x - 7)
Thus, the requried expression of the given expression which is a product of two binomials is (x - 3)(x - 7).

There's 6,954 cases filed with Surpreme court only 82 were chosen by Surpreme court. what percentage was decided by the court ?
Answer:
1.2%
Step-by-step explanation:
Since only 82 were chosen by supreme Court,
The total is 6954
To calculate the percentage of the case decided by the court
82/6954 ×100
8200/6954
1.179~1.2
So the final answer is 1.2%
Final answer:
The percentage of cases decided by the Supreme Court compared to those filed is approximately 1.18%.
Explanation:
To calculate the percentage of cases decided by the Supreme Court out of the total number of cases filed, we use the formula for finding a percentage: (Number of cases decided / Total cases filed) × 100. In this scenario, the Supreme Court decided 82 cases out of 6,954 cases filed.
So, the calculation would look like this:
(82 / 6,954) × 100 = (0.01179) × 100 ≈ 1.18%
Therefore, approximately 1.18% of the cases filed with the Supreme Court were decided by the court.

Lance bought 12 quarts of lemonade so that everyone who came to his party could have exactly 1/3 quart. How many people did Lance invite to his party?
Lance invited 36 people to his party.
Step-by-step explanation:
It is given that,
Lance bought 12 quarts of lemonade.Everyone who came to his party could have exactly 1/3 quart.We know that,
The total quarts of lemonade available for the party = 12
Each person in the party consumes = 1/3 quart.
We need to find out how many people did Lance invited to his party.
To find the number of people :
Let us consider 'x' be the number of people invited to the party.
Total lemonade = number of people × lemonade for each person.
⇒ 12 = x × 1/3
⇒ 12×3 = x
⇒ x = 36 people
Therefore, Lance invited 36 people to his party.

Suppose y varies directly with x. Write an equation if y=75when x=25
Answer:
y = 3x
Step-by-step explanation:
The standard format of a directly proportional equation goes by the format of y = k × x. The question asks us to write an equation if y = 75 when x = 25 and y varies directly with x.
So we substitute the values y = 75 and x = 25 in the equation y = k × x
K = constant, we have to work this out
75 = k × 25
75 ÷ 25 = k
k = 75 ÷ 25
k = 3
k = 3 So then we put this back into the original y = k × x to find our final equation which is y = 3x

Janeel has a 10 inch by 12 inch photograph. She wants to scan the photograph, then reduce the results by the same amount in each dimension to post on her Web site. Janeel wants the area of the image to be one eight of the original photograph. Write an equation to represent the area of the reduced image. Find the dimensions of the reduced image.
Correct Answer:
A) [tex](10-x)(12-x)=15[/tex]
B) Dimensions are : Length = 10-x = 3 inch , Breadth = 12-x = 5 inch
Step-by-step explanation:
a. Write an equation to represent the area of the reduced image.
Let the reduced dimensions is by x , So the new dimensions are
[tex]length=10-x\\breadth=12-x[/tex]
According to question , Area of new image is :
⇒ [tex]Area = \frac{1}{8}Length(breadth)[/tex]
⇒ [tex]Area = \frac{1}{8}(10)(12)[/tex]
⇒ [tex]Area = 15[/tex]
So the equation will be :
⇒ [tex](10-x)(12-x)=15[/tex]
b. Find the dimensions of the reduced image
Let's solve : [tex](10-x)(12-x)=15[/tex]
⇒ [tex]120-10x-12x+x^2=15[/tex]
⇒ [tex]120-22x+x^2=15[/tex]
⇒ [tex]x^2-22x+105=0[/tex]
By Quadratic formula :
⇒ [tex]x = \frac{-b \pm \sqrt{b^2-4ac} }{2a}[/tex]
⇒ [tex]x = \frac{22 \pm8 }{2}[/tex]
⇒ [tex]x = \frac{22 +8 }{2} , x = \frac{22 -8 }{2}[/tex]
⇒ [tex]x = 15 , x =7[/tex]
x = 15 is rejected ! as 15 > 10 ! Side can't be negative
⇒ [tex]x =7[/tex]
Therefore, Dimensions are : Length = 10-x = 3 inch , Breadth = 12-x = 5 inch
