Pete Corporation produces bags of peanuts. Its fixed cost is $18,200. Each bag sells for $3.43 with a unit cost of $1.83. What is Pete’s breakeven point?
Answers
Let's call x to the bags of peanuts. One bag has a variable cost of $1.83, then the variable cost of x bags is 1.83x dollars.
The total cost of production for the corporation is obtained by adding fixed and variable costs. In this case, the total cost is 18,200 + 1.83x dollars.
The revenue for the corporation of 1 bag is $3.43, then of x bags is 3.43x dollars.
When the revenue and the total cost are equal, the breakeven point is reached, in this case:
18,200 + 1.83x = 3.43x
18,200 = 3.43x - 1.83x
18,200 = 1.6x
18,200/1.6 = x
11375 = x
The cost of production of 11375 bags is:
Total Cost = 18,200 + 1.83*11375
Total Cost = 18,200 + 20816.25
Total Cost = 39016.25
Pete’s breakeven point is (11375, 39016.25), or, 11375 bags and $39,016.25
Four friends participated in a free contest for charity. Erin scored 4 less points than Taylor. Nya scored three times as many points as Erin. Aaron scored 10 more points than Nya. Together the four friends scored a total of 158 points. Find how many points each friend made :How many points Taylor scored :Erin scored : Nya scored :Aaron scored:
Answers
Taylor's scored 22 points
Erin scored 18 points
Nya scored 54 points
Aaron scored 64 points
Explanation:Let Taylor's point = x
Erin scored 4 less points than Taylor:
Erin's score = x - 4
Nya scored three times as many points as Erin:
Nya's score = 3(x - 4)
Aaron scored 10 more points than Nya:
Aaron's score = Nya's score + 10
= 3(x - 4) + 10
The total score of the four friend = 158 points
Taylor's score + Erin's score + Nya's score + Aaron's score = 158
x + (x - 4) + 3(x -4) + 3(x-4) + 10 = 158
Expand the parenthesis:
x + x -4 + 3x - 12 + 3x - 12 + 10 = 158
collect like terms:
x + x + 3x + 3x - 4 - 12 - 12 + 10 = 158
8x - 18 = 158
8x = 158 + 18
8x = 176
Divide both sides by 8:
8x/8 = 176/8
x = 22
Taylor's scored 22 points
Erin scored : x-4 = 22- 4 = 18 points
Nya scored : 3(x-4) = 3(22-4) = 3(18) = 54 points
Aaron scored: 3(x-4) + 10 = 54 + 10 = 64 points

The height of a triangle is 3 m

76 m2. Find the height of the triangle. Help me!
Answers
The triangle has a height of 19 meters.
How to determine the height of a triangle
In this problem we find the area of a triangle, in square meters, and the relationship between its height (h) and its base length (b), both in meters. We must solve the following expression to determine the height:
A = (1 / 2) · b · h
h = 3 + 2 · b
A = 76
Then,
76 = (1 / 2) · b · (3 + 2 · b)
152 = b · (3 + 2 · b)
152 = 3 · b + 2 · b²
2 · b² + 3 · b - 152 = 0
Finally, we find the roots of the polynomial by quadratic formula:
b₁ = 8, b₂ = - 19 / 2
Since, lengths are non-negative real numbers, the only possible solution is b = 8 and the height of the triangle is:
h = 3 + 2 · 8
h = 19
The height of the triangle is 19 meters.

In each of the following problems, how do I graph the line with the given slope m and y-intercept b.

Answers
The graph is shown the following slope intercept formula y = 5/3x -4.
What exactly is a slope?A line's slope can be used to determine how steep it is.The slope is calculated mathematically as "rise over run" (change in y divided by change in x).When a line's equation is expressed as y = mx + b, the slope-intercept representation of the equation is used.M displays the slope of the line.B is the value of b where the y-intercept is located (0, b).For instance, the slope and y-intercept of the equation y = 3x - 7 are 3 and 0, respectively.So, the slope-intercept formula: y = mx + b
Where, = 5/3x and b = -4.Now, substitute the values in the formula and graph the slope-intercept on the graph as follows:
y = 5/3x -4(Refer to the graph attached below )
Therefore, the graph is shown the following slope intercept formula y = 5/3x -4.

The Ferris wheelThe community loves the Ferris Wheel because when they are at the top of the wheel they can look for their house and it has long been a family favorite. The company sent you a Ferris wheel that has a radius of 40 ft. and each car is 5 ft. tall. The people can’t start to look for their houses until they get above the tents of the carnival and those tents are 20ft tall. The Ferris wheel has 20 passenger cars and it takes 12 minutes to have all the cars filled. Once all cars are filled the Ferris wheel runs at 1 rotation for every 2 minutes for a total of 8 minutes.Once someone has boarded the Ferris wheel, how long will it take for them to be able to start looking for their house?How long will they have to search for their house?
Answers
Given:
radius of Ferris wheel = 40 ft
height of a car = 5 ft
height of a tent = 20 ft
no. of passenger cars = 20
time to load all cars = 12 minutes
time for 1 rotation = 2 minutes
time for all rotations = 8 minutes
What we want to know is how many degrees the car will have to travel along the circle before it reaches a height of 20 ft.
We can draw a triangle to represent the unknown and find the angle.
The total height from the ground to the center of the Ferris wheel is 45 ft (5ft car height + 40 ft radius). We deduct the 20ft height of the tent so we get the side of the right triangle we're using to solve for the missing angle. That height is 25 ft.
The radius also serves as the hypotenuse of the triangle.
We can then use the following to solve for the angle theta:
[tex]\begin{gathered} \cos\theta=\frac{adjacent}{hypotenuse} \\ \\ \cos\theta=\frac{25}{40} \\ \\ \cos^{-1}(\cos\theta)=\cos^{-1}(\frac{25}{40}) \\ \\ \theta=51.3\degree \end{gathered}[/tex]Now we know that the car must travel 51.3 degrees along the circle before it gets to a height where it can see above the tents. If one rotation is 360 degrees and it takes 2 minutes to complete one round, then to find the time it will take to travel 51.3 degrees, we use the following equation:
[tex]\begin{gathered} \frac{360\degree}{2minutes}=\frac{51.3\degree}{x\text{ }minutes} \\ \\ x=\frac{51.3(2)}{360} \\ \\ x=0.285\text{ minutes or }17.1\text{ seconds} \end{gathered}[/tex]It will take them 17.1 to be able to start looking for their house.
Now every time the car goes around the path of the Ferris wheel, for 17.1 going up and another 17.1 seconds going down, they will not be able to look for their house.
17.1 seconds x 2 x 4 turns = 136.8 seconds
8 minutes - 136.8 seconds = 480 - 136.8 = 343.2 seconds or 5 minutes and 43.2 seconds
They have 5 minutes and 43.2 seconds to look for their house.

What is an inverse matrix?An inverse of a matrix, A, is a matrix [tex] A^{-1}[/tex], that multiplies matrix A to give an identity matrix.
The inverse matrix method involves defining and making use of a coefficient matrix, A, a variable matrix, X, and a constant matrix, B, which are obtained from the system of equations as follows;
A·X = B
The system of equations is presented as follows;
3·x + 4·y = 18
4·x - y = 5
From the above system of equations, we have:
[tex]The \ coefficient \ matrix, \ A = \begin{bmatrix} 3&4 \\ 4& -1 \end{bmatrix}[/tex]
[tex]The \ variable \ matrix, \ X = \begin{bmatrix} x \\ y \end{bmatrix}[/tex]
[tex]The \ constant \ matrix, \ B = \begin{bmatrix} 18 \\ 5 \end{bmatrix}[/tex]
From the equation, A·X = B, we have;
[tex]\therefore X = \dfrac{B}{A} = A^{-1} \times B[/tex]
Where: A⁻¹ is the inverse matrix of A, which is found as follows;
[tex]If\ A = \begin{bmatrix} a&b \\ c&d \end{bmatrix}[/tex]
[tex]Then, \ A^{-1} = \dfrac{1}{a\cdot d-b\cdot c} \cdot \begin{bmatrix} d& -b \\ -c& a \end{bmatrix}[/tex]
Which gives the value of A⁻¹ obtained from the coefficient matrix, A = [tex]\begin{bmatrix} 3&4 \\ 4& -1 \end{bmatrix}[/tex] as follows;
[tex]A^{-1} = \begin{bmatrix} 3 & 4 \\ 4 & - 1 \end{bmatrix}^{ - 1} = \dfrac{1}{(3 \times - 1) - (4 \times 4)} \times \begin{bmatrix} - 1 & - 4 \\ - 4 & 3 \end{bmatrix}[/tex]
[tex]A^{-1} = \dfrac{1}{(3 \times - 1) - (4 \times 4)} \times \begin{bmatrix} - 1 & - 4 \\ - 4 & 3 \end{bmatrix} = \begin{bmatrix} \dfrac{ - 1}{ - 19} & \dfrac{ - 4}{ - 19} \\\\ \dfrac{ - 4}{ - 19} & \dfrac{3}{ - 19} \end{bmatrix}[/tex]
The variable matrix, [tex]X = A^{-1} \times B[/tex], which gives the value of the variables in the solution is therefore;
[tex]X = \begin{bmatrix} x \\ y \end{bmatrix} = \begin{bmatrix} \dfrac{ - 1}{ - 19} &\dfrac{ - 4}{ - 19} \\ \\\dfrac{ - 4}{ - 19} &\dfrac{3}{ - 19} \end{bmatrix} \times \begin{bmatrix} 18 \\ 5 \end{bmatrix} = \begin{bmatrix} 2 \\ 3 \end{bmatrix}[/tex]

(b) Find the probability that a randomly selected ART cycle that resulted in a pregnancy did not produce a multiple birth.(c) Would it be unusual for a randomly selected ART cycle to result in a pregnancy and produce a multiple birth?
Answers
In this case, we'll have to carry out several steps to find the solution.
Step 01:
Data:
assisted reproductive technology (ART) cycles:
pregnancies = 36%
pregnancies resulted in multiple births = 26%
Step 02:
a.
p (pregnancies) = 36% = 36/100 = 0.36
pregnancies resulted in multiple births = 26% = 26/100 = 0.26
p(pregnancies resulted in multiple births) = 0.36*0.26 = 0.0936
b.
p (pregnancy did not produce a multiple birth) = 1 - 0.0936 = 0.9064
c.
Indeed, the probability of multiple pregnancies is low 9.36%.

If I flip [tex]\frac{1}{1}[/tex] upside down, I get the same fraction which is equal to 1. Now I will take the opposite sign. Since it is positive, the new slope will be negative
slope -1
x = -1
y = -1
I am using the point that will be on the new line. This is the midpoint that we just found (-1,-1) I am going to plug in the number that I know and solve for b or the y=intercept.
y = mx + b
- 1 = -1(-1) + b
-1 = 1 + b Subtract 1 from both sides of the equation
-2 = b
y = mx + b
y = -1x -2
or
y = -x -2
x + y = 5 y - 2x = -4
Answers
x = 3, y = 2
Explanations:The equations are:
x + y = 5......................(1)
y - 2x = -4...................(2)
Make x the subject of the the formula
x = 5 - y...............(3)
Substitute equation (3) into equation (2)
y - 2(5 - y) = -4
y - 10 + 2y = -4
3y = -4 + 10
3y = 6
y = 6 / 3
y = 2
Substitute the value of y into equation (3)
x = 5 - 2
x = 3

The rational number is -91/100 or -0.91.
What is Rational number?Any number of the form p/q, where p and q are integers and q is not equal to 0, is a rational number. The letter q stands for the set of rational numbers.
The word "ratio" is where the word "rational" first appeared. Rational numbers are therefore closely tied to the idea of fractions, which stand for ratios. In other terms, a number is a rational number if it can be written as a fraction in which the numerator and denominator are both integers.
Given:
We have to find the rational number between -0.45 and -0.46
Now, make both decimal into fraction
-0.45 and -0.46
-45/100 and -46/100
Now, multiply 2
-45/100 x 2/2 and -46/100 x 2/2
-90/100 and - 92/100
Hence, the rational number is -91/100 or -0.91.
