trey has a peanut allergy, so he eats granola bars that are nut-free. a box of nut-free granola bars cost $4.50 after a 10% discount. what is the original price of the box of granola bars
The original price of the granola bars before the 10% discount was $5.00. To determine this, the given discounted price was divided by 0.90, which represents the price after a 10% reduction.
The original price of a box of nut-free granola bars before the discount can be calculated by reversing the 10% discount process. Since Trey paid $4.50 after the discount, we can represent the original price as x. The discount applied to x would be 0.10 times x (which is how a 10% discount is calculated), and the price after the discount is x minus the discount. So the equation to solve is x - 0.10x = $4.50.
Simplify this equation to find x:
0.90x = $4.50.
Now, divide both sides of the equation by 0.90 to find x:
x = $4.50 / 0.90.
x = $5.00.
Therefore, the original price of the box of granola bars before the 10% discount was $5.00.

A function, f, passes through the points (1,1), (2,7) and (3,25). A function, g, passes through the points (1,36), (2,43) and (3,50).
Select the correct answer.
Answer:
As the value of x increases, the value of f(x) will eventually exceed the value of g(x) is the correct option.
Step-by-step explanation:
A function, f, passes through the points (1,1), (2,7) and (3,25).
The equation of the function 'f' can be written as:
The f(x) is obtained by:
[tex]f\left(x\right)=3f\left(x-1_\right)+4[/tex]
[tex]f\left(4\right)=3f\left(3\right)+4=\left(25\times 3\right)+4=75+4=79[/tex]
A function, g, passes through the points (1,36), (2,43) and (3,50).
The g(x) is obtained by:
[tex]g\left(x\right)=g\left(x-1\right)+7[/tex]
[tex]g\left(4\right)=g\left(4-1\right)+7=g\left(3\right)+7=50+7=57[/tex]
So, value of f(x) at x = 4 exceeds the value of g(x) at x = 4.
Therefore, as the value of x increases, the value of f(x) will eventually exceed the value of g(x) is the correct option.

A certain forest covers an area of 8.25%. Suppose that each year this area decreases by 4800km^2. What will the area be after 5 years?
Solution:
The decreasing function is given as:
[tex]y = a(1-r)^t[/tex]
Where,
y is future value
a is initial value
r is decreasing rate
t is number of years
From given,
a = 4800
t = 5
[tex]r = 8.25 \% = \frac{8.25}{100} = 0.0825[/tex]
Therefore,
[tex]y = 4800(1 - 0.0825)^5\\\\y = 4800 \times 0.9175^5\\\\y = 4800 \times 0.6501\\\\y = 3120.841[/tex]
Thus the area after 5 years is 3120.841 square kilometer
Two lines intersect to form the angles shown.
Which statements are true?
Select each correct answer.
m<1=100 degrees
m<3=80 degrees
m<2= 80 degrees
m<3=m<1
Answer:
m∠3=80 degrees
m∠3=m∠1
Step-by-step explanation:
When two lines intersect, the opposite angles are equal. They are called vertical angles. That means for this problem:
m∠1 = m∠3 *Last option is true
m∠2 = 100° *Third option is false
A straight line is always 180°. When it is cut up, the sum of the angles is 180°. They are called suppementary angles. These are supplementary:
100° + m∠3 → m∠3 = 80° *Second option is true
m∠1 + 100° → m∠1 = 80° *First option is false
m∠1 + m∠2 → One or the other is 100° and 80°
m∠2 + m∠3 → One or the other is 100° and 80°
Kendra is babysitting her cousins, who are quintuplets. At snacktime, Kendra puts 5 plates on the table. She cuts apples into slices and places an equal number of slices on each cousin's plate. There is a total of 35 apples slices on the plates.
Which equation can you use to find the number of apple slices s on each plate?
Answer:
Kendra is watching over 5 children. She wants to be sure that they each have an even number of apple slices. There are 35 apple slices total. She wants to take 35 and put it equally into 5 groups.
Your equation would be 5s=35, where s would be the total amount of apple slices on each plate.
To solve this equation you would divide both sides by 5 to get 7. s=7 (35/5=7)
Each quintuplet would be 7 apple slices.

Find the minimum value of
C = 4x + 3y
Subject to the following constraints:
x 20
y20
2x + 3y > 6
3x – 2y = 9
x + 5y = 20
Final answer:
To find the minimum value of C given the constraints, one must plot these constraints, find the feasible region's vertices, evaluate C at each vertex, and select the minimum value obtained. The minimum value of C = 4x + 3y, given the constraints and the corrected understanding of them, is 29.
Explanation:
To find the minimum value of C = 4x + 3y subject to the given constraints, we need to first correct the constraints provided, as it seems there might be a misunderstanding in how they were presented. Assuming the constraints meant to be:
1. [tex]\(x \geq 0\)[/tex]
2. [tex]\(y \geq 0\)[/tex]
3. [tex]\(2x + 3y \geq 6\)[/tex]
4.[tex]\(3x - 2y = 9\)[/tex]
5.[tex]\(x + 5y = 20\)[/tex]
We will solve the system of equations (4) and (5) to find the values of x and y that satisfy these conditions, and then we will check if these values satisfy all other constraints including (3). If they do, we'll use these values to find C.
Solving the equations simultaneously:
From equation (4): 3x - 2y = 9
From equation (5): x + 5y = 20
Multiplying equation (5) by 3 to eliminate x, we get:
3(x + 5y) = 3(20)
3x + 15y = 60
Now, subtract equation (4) from this result to eliminate x:
3x + 15y - (3x - 2y) = 60 - 9
3x + 15y - 3x + 2y = 51
17y = 51
y = 3
Substitute y = 3 into equation (5) to find x:
x + 5(3) = 20
x + 15 = 20
x = 5
Now, check if [tex]\(x = 5\) and \(y = 3\) satisfy the constraint \(2x + 3y \geq 6\):[/tex]
[tex]\[2(5) + 3(3) \geq 6\][/tex]
[tex]\[10 + 9 \geq 6\][/tex]
[tex]\[19 \geq 6\] - This is true.[/tex]
Since x = 5 and y = 3 satisfy all the constraints, we can calculate \(C\):
C = 4x + 3y
C = 4(5) + 3(3)
C = 20 + 9
C = 29
Therefore, the minimum value of C = 4x + 3y, given the constraints and the corrected understanding of them, is 29.

The soccer team is selling tubs of cookie dough and brownie mix. Elaina raised $75 by selling one tub of cookie dough and five tubs of brownie mix. Megan raised $141 by selling three tubs of cookie dough and eight tubs of brownie mix. How much is a tub of brownie mix?
The cost of one tub of brownie mix = $12
Step-by-step explanation:
Step 1 :
Let x represent one tub of cookie mix's cost and y represent one tub cookie mix's cost
Total amount raised by Elaine = $75
Number of cookie mix tub sold by Elaine = 1
Number of brownie mix tub sold by Elaine = 5
This can be represented by the equation
x + 5 y = 75 => x = 75 - 5y
Step 2 :
Total amount raised by Megan = $141
Number of cookie mix tub sold by Megan = 3
Number of brownie mix tub sold by Megan = 8
This can be represented by the equation
3 x + 8 y = 141
Step 3 :
Solving the equations obtained in the above steps we have ,

On a container ship there were 30 small containers that each weighed 3 tons, 20 medium
containers that each weighed 5 tons, and 10 large containers that each weighed 8 tons.
Find the mean weight of the containers on this ship.
The mean weight of the containers on the ship is found by adding the total weight of all the containers (270 tons) and dividing by the total number of containers (60), giving a mean of 4.5 tons per container.
Explanation:In this problem, we are asked to find the mean weight of the containers on a ship. The mean is the average value of a set of numbers, found by adding all the numbers together and then dividing by the quantity of numbers.
First, let's compute the total weight of all the containers. The weight of the 30 small containers are 30 containers * 3 tons each = 90 tons. The weight of the 20 medium containers are 20 containers * 5 tons each = 100 tons. The weight of the 10 large containers are 10 containers * 8 tons each = 80 tons.
So, the total weight of all the containers is 90 tons + 100 tons + 80 tons = 270 tons. And the total number of containers is 30 + 20 + 10 = 60 containers.
So, the mean weight of the containers is 270 tons Total Weight / 60 = 4.5 tons/container. So, the mean weight of the containers on the ship is 4.5 tons.

the first term of an arithmetic sequence is -27. the common difference of the sequence is 6. What is the sum of the first 30 terms
Answer:
1800
Step-by-step explanation:
The sum to n terms of an arithmetic sequence is
[tex]S_{n}[/tex] = [tex]\frac{n}{2}[/tex] [ 2a₁ + (n - 1)d ]
where a₁ is the first term and d the common difference
Here a₁ = - 27 and d = 6, thus
[tex]S_{30}[/tex] = [tex]\frac{30}{2}[/tex] [ (2 × - 27) + (29 × 6) ]
= 15( - 54 + 174)
= 15(120)
= 1800
The sum of the first 30 terms of the arithmetic sequence, is 1800.
In an arithmetic sequence, the sum of the first n terms can be calculated using the formula:
Sum = n/2 × (2a + (n-1)d), where:

The value of x obtained after solving the equation x² + 2x + 9 = 0 will be x = -1 ±2i √(2)(x equals negative 1 plus or minus 2 I square root of 2).Option D is correct.
What is a quadratic equation?Any equation of the form ax²+bx+c=0 where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic equation.
As we know, the formula for the roots of the quadratic equation is given by:
[tex]\rm x = \dfrac{-b \pm\sqrt{b^2-4ac}}{2a}[/tex]
it is given that,
x² + 2x + 9 = 0
Rearrange the equation as
x² + 2x = - 9
Add 1 on both sides of the equation,
x² + 2x +1 = - 9 +1
x² + 2x +1 = - 8
(x+1)² = -8
Taking square root,
(x+1) = √ -8
Subtract 1 from both sides,
x+1-1 = -1 ±√(-8)
x = -1 ±√(-8)
√(-8) can be written as,
√(-8) = 2i√2
Substitute the values,
x = -1 ±2i sqrt(2)
Thus, the value of x obtained after solving the equation x² + 2x + 9 = 0 will be x = -1 ±2i √(2)(x equals negative 1 plus or minus 2 I square root of 2).Option D is correct.
