A two-pound mixture of raisins and peanuts costs $7.50. The raisins cost $3.25 a pound and the peanuts costs $5.75 a pound. How much does each ingredient weight in the mixture?
he mixture refers to the one pound mix of peanuts and raisins that cost $7.50.
So you need to figure out how much of that 1 lb is raisins and how much is peanuts based on how much they each cost separately.
r=raisins, p=peanuts
(r x $3.25) + (p x $5.75) = $7.50
The weight of the ingredients in the mixture are 1.8 pound and 0.2 pound respectively.
What is a system of linear equations?A system of linear equations is a group of equations having same number of variables and degree.
For the n number of variables n number of equations are required.
On the basis of number of solutions a system of equations can be classified as consistent and inconsistent.
The given problem can be solved as follows,
Suppose the amount of raisins be x pound,
And, the amount of peanuts be y pound,
Now, the equation for the total amount is given as,
x + y = 2 (1)
And, for the cost as,
3.25x + 5.75y = 7.50 (2)
Multiply equation (1) by 3.25 and then subtract from (2) as follows,
3.25(x + y) - (3.25x + 5.75y) = 2 × 3.5 - 7.50
=> -2.5y = -0.5
=> y = 0.2
Then, x + 0.2 = 2
=> x = 1.8
Hence, the weight of raisins and peanuts in the mixture is given as 1.8 pound and 0.2 pound respectively.

A soccer team won 11 games last year. This year they won 13 games. What was the percent increase in the number of games won? Round your answer to the nearest whole percent.
Answer:percent increase in the number of games won= 18%
Step-by-step explanation:
Number of game won last year = 11
Number of games won this year = 13
Percent increase = Increase in number of games won/ Number of games won lasT year ) X 100
= (13-11)/ 11 X 100

Find the solution set of the following equations:
2y=2x+7
X=y+2
Answer:
The system of equations has no solution.
Step-by-step explanation:
Given the system of equations
2y = 2x+7
x = y+2
solving the system of equations
[tex]\begin{bmatrix}2y=2x+7\\ x=y+2\end{bmatrix}[/tex]
Arrange equation variables for elimination
[tex]\begin{bmatrix}2y-2x=7\\ -y+x=2\end{bmatrix}[/tex]
Multiply -y+x=2 by 2: -2y+2x=4
[tex]\begin{bmatrix}2y-2x=7\\ -2y+2x=4\end{bmatrix}[/tex]
so adding
[tex]-2y+2x=4[/tex]
[tex]+[/tex]
[tex]\underline{2y-2x=7}[/tex]
[tex]0=11[/tex]
so the system of equations becomes
[tex]\begin{bmatrix}2y-2x=7\\ 0=11\end{bmatrix}[/tex]
0 = 11 is false, therefore the system of equations has no solution.
Thus,
No Solution!

Ginny is making homemade pizzas for her family. The recipe makes 70 ounces of dough, but she made more that to ensure she had enough to feed everyone. She plans to freeze 28 ounces for next week, and the rest of the dough will be split evenly to make 3 pizzas. A. Write an inequality to represent the maximum weight of each pizza. Response area b. Each of Ginny's pizzas will weigh more than Response area ounces.
Answer:
14 ounce
Step-by-step explanation:
Given that:
Ounces of dough used in making recipe = 70 ounces
Number of ounces frozen = 28 ounces
Number of pizzas made from dough left = 3
Number of ounces left = total made - number frozen
Number of ounces left = 70 - 28 = 42
Weight of pizza made :
Number of ounces left / number of Pizzas made
42 / 3 = 14
Hence, maximum weight of each pizza made will weigh more than 14 ounces

PLEASE HELP THIS IS TIMED!!!!!!!!!!!!!!!!!!!! A gumball machine had 78 gumballs. Each person who put a coin into the machine gets 3 gumballs. After a certain number of people got gumballs, there were 54 gumballs remaining. Estimate how many people got gumballs out of the machine.
Answer:
8 people got gumballs out of the machine.
Step-by-step explanation:
Given that:
Number of gumballs in machine = 78
Number of gumballs on each coin = 3
Number of gumballs left = 54
Let,
x be the number of people who put coin
Gumballs left = Total gumballs - 3*Number of people
54 = 78 - 3x
3x = 78 - 54
3x = 24
Dividing both sides by 3
[tex]\frac{3x}{3}=\frac{24}{3}\\x=8[/tex]
Hence,
8 people got gumballs out of the machine.

Jaylin has a scale model of a train. 2 cm in the model represents 3 feet in a real train. The height of the model train is 10.2 cm. What is the height of the rail train?
Answer:
the height of the rail train is 15.3 feet
Step-by-step explanation:
The computation of the height of the rail train is given below:
= Height of the model train ÷ 2 cm × real train
= 10.2 cm ÷ 2 cm × 3 feet
= 15.3 feet
Hence, the height of the rail train is 15.3 feet
We basically applied the above formula in order to get the height of the rail train

Cheddar cheese costs $3.45 per pound. Which equation best represents the total cost, c, of pounds, p, of cheddar cheese?
Answer:
c = 3.45 * p
Step-by-step explanation:
Since the total cost of Cheddar Cheese is dependant on the number of pounds that are being purchased then to calculate the total cost we would need to multiply the price per pound by the number of pounds being purchased. Therefore, the following equation would best represent the total cost of the cheddar cheese...
c = 3.45 * p
In a stationery design, the number of ovals is proportional to the number
of squares. How many squares will there be when there are 75 ovals?
Question Help
When there are 75 ovals, how many squares are there?
Answer:
75 ÷k number of squares based on the k value
Step-by-step explanation:
Let us suppose the ovals number be x
And, the square number be y
Now in the case when the ovals number is proportional to the square number
So, it would be defined as
x∝y
And,
x = ky
Here k is the constant
Now
If there are 75 ovals,
So, x = 75
Now put this in the above equation
75 = kx
x = 75 ÷k
A factory makes 640brushes in 4 hours.Does the equation y=150x model the number of brushes made each hour?
Answer:
No it doesn't
Step-by-step explanation:
The equation we have is
Y = 150x
We have x = 4 hours
This is a simple question. We have to plug in the x = 4 in the equation to find out if we would have 640 brushes. If y = 640, then it models it. But if y is not equal to 640, it doesn't.
So let's solve this to see for ourselves.
Y = 150(x)
We put the value of x
Y = 150(4)
Y = 600
So we can see that the equation does not model the number of brushes made each hour. This equation models 600 brushes and not 640.

If the last digit is 5 or higher (5,6,7,8,9,) it rounds up
If the last digit is 4 or lower (1,2,3,4) it rounds down
Example:
$7.60 would be rounded to $8 because 6 is higher than 5, or in this case, 60 is higher than 50
$4.40 would be rounded to $4 because 4 is lower than 5, or in this case, 40 is lower than 50

The area of the triangle is A = 61.8 units²
What is a Triangle?A triangle is a plane figure or polygon with three sides and three angles.
A Triangle has three vertices and the sum of the interior angles add up to 180°
Let the Triangle be ΔABC , such that
∠A + ∠B + ∠C = 180°
The area of the triangle = ( 1/2 ) x Length x Base
For a right angle triangle
From the Pythagoras Theorem , The hypotenuse² = base² + height²
if a² + b² = c² , it is a right triangle
if a² + b² < c² , it is an obtuse triangle
if a² + b² > c² , it is an acute triangle
Given data ,
Let the triangle be represented as ΔABC
Now , length of side AC is 10 and the length of CB is 13.
Angle BAC is 64° and angle ACB is 72°
Now , the area of the triangle is A = ( 1/2 ) x Length x Base ( sin 72° )
A = 1/2 ( 10 ) ( 13 ) sin 72°
A = 61.8 units²
Hence , the area is A = 61.8 units²
