At their going out business sale, Bill’s Bikes sold 36 bikes and had 58 left. Which equation could be used to find x, the number of bikes the store had originally.
The equation that could be used to find x, the number of bikes the store had originally, is (x-94) = 0.
According to the question,
We have the following details:
Bill has sold 36 bikes and is left with 58 bikes more.
Now, the number of bikes the store had originally is given to be x.
So, we have:
x = Number of bikes sold + Number of bikes left
x = 36+58
x = 94
x-94 = 0 (94 was positive on the right hand side. So, it is negative on the left hand side.)
Hence, the equation that could be used to find number of original bikes in Bill's store is x-94 = 0.

The decimal number 3.16 in the form of the simplest fraction is 79/25.
The portion or part of the complete item is represented by a fraction. It stands for the equal components of the whole. The denominator and numerator are the two components of a fraction. The top number is referred to as the numerator, and the bottom number is referred to as the denominator.
Consider the decimal number,
Let x = 3.16
Then,
x = 3.16 = 316/100
The fraction then can be simplified as,
x = ( 158 × 2)/ (50 × 2)
x = 158/50
x = ( 79 × 2)/ ( 25 × 2 )
x = 79/25

Points A and B are on a circle with centre O and radius n so that AOB = (360/n). Sector AOB is cut out of the circle. Determine all positive integers n for which the perimeter of sector AOB is greater than 20 and less than 30
The integer n = 25 is the only value so that the sector AOB is greater than 20 and less than 30.
How to find the positive integers associated to the diameter of a circle
In this problem we find the sector generated by line segments OA and OB, where O is the center of the circle and the points A and B are on the circle:
20 < 360 / n < 30
20 · n < 360 < 30 · n
First, we determine the factorial decomposition of 360:
360 = 2³ × 3² × 5
Second, find the value of n associated to each limit of the inequality:
Lower limit
360 = (2² × 5) × (2 × 3²)
360 = 20 × 18
n = 18
Upper limit
360 = (2 × 3 × 5) × (2² × 3)
360 = 30 × 12
n = 12
Third, find the values that are between 12 and 18:
x = 2³ × 3
x = 24
n = 360 / 24
n = 15
The only integer that satisfies the inequality is 15.

What is an Undefined Slope of a Line?An undefined slope of a line can be described as the slope of a vertical line that has no run but only rise. That is, the x-coordinates do not change even though the y-coordinates of the line are changing.
Thus, the change in x-coordinates is always 0.
Slope = change in y / change in x.

What is Mean Absolute Deviation?
The average distance between each data value and the mean is known as the mean absolute deviation (MAD) of a data set. A measure of variance in a data set is the mean absolute deviation. We may determine how "spread out" the values in a data collection are by looking at the mean absolute deviation.

The mean would be 100
|data - mean value| = 96-100 = 4
38-100 = 62
162-100 = 62
65-100 = 35
178-100 = 78
112-100 = 12
57-100 = 43
143-100 = 43
135-100= 35
104-100 = 4
88-100 = 12
22-100 = 78
Now, sum of |data - mean values| = 468
The mean absolute deviation:
= sum of |data - mean values| / number of values
= 468 / 12
= 39

Find the number of units where the break-even point is located, i.e., find n when P(n) = 0.The number of units, n, where the break-even point is located, isHint: Did you factor the GCF? Then reduce your equation to smaller coefficients?
Given the function:
[tex]P\mleft(n\mright)=-25n^2+300n+1125[/tex]You know that "P" is the profit for a certain "n" commodity (in units).
You need to find the value of "n" when:

1. Substitute this value into the function:
[tex]P(n)=0[/tex]Then:
[tex]\begin{gathered} 0=-25n^2+300n+1125 \\ \\ -25n^2+300n+1125=0 \end{gathered}[/tex]2. Divide both sides of the equation by -25:

a. Use the formulas shown to write the company's profit function, P, from producing and selling x radios.
b. Find the company's profit if 23,000 radios are produced and sold.
***
Answer:
(a) The profit function is P(x) = 89x - 90,000.
(b) The company's profit at x=23,000 is 1,957,000.
Step-by-step explanation:
Given,
The cost function of the company is C(x)=90,000 +42x and
The revenue function is R(x) = 47x
where x is the number of radios.
(a)
The company's profit function, P, is from producing and selling x radios is
The formula for profit:
Profit (P) = Revenue (R) - Cost (C)
P = R - C
P = 47x - 90,000 + 42x
P = (47x + 42x) - 90,000
P = 89x - 90,000
For (a), The company's profit function, P, from producing and selling x radios is P = 89x - 90,000
(b)
The radios produced and sold are 23,000
So, x = 23,000
putting x value in the profit function, P
P = 89x - 90,000
P = 89 x 23,000 - 90,000
P = 2,047,000- 90,000
P = 1,957,000
For (b), the company's profit at x = 23,000 is 1,957,000.

Here, we are given that Shelby prepared 9 kilograms (kgs) of dough after working 3 hours.
from this information we can calculate the amount of dough she can prepare in 1 hour.
3 hours ⇒ 9 kgs
1 hour ⇒ 9/3 kgs
9/3 = 3
Thus, she will prepare 3 kgs of dough in 1 hour.
Now, we are given that Shelby prepares 15 kgs of dough in all.
we have, 3 kgs ⇒ 1 hour
Thus, 15 kgs ⇒ 15/3 hours

The value for h'(-1) is 1
Given the tangent line to the graph of y=h(x) at the point (-1,4) passes through (3,6), to get h(-1) and h'(-1), we should calculate the following:
Gradient of the tangent line:
Gradient=change in y axis/change in x axis=Δy/Δx
Using the x and y coordinates (-1,4) and (3,6)
Gradient=(6-4)/(3--1)
=2/4
=1/2
Gradient=1/2 or 0.5
Equation of the tangent line:
This should be in the form of y=mx+c, where m is the gradient of the line
We use the gradient and one of the x and y coordinates get the equation of the tangent line
Gradient=change in y axis/change in x axis=Δy/Δx, and gradient was found as 1/2
Δy/Δx=1/2
(y-4)/(x--1)=1/2
(y-4)/(x+1)=1/2
2y-8=x+1
y=(1/2)x+4.5
Equation of the tangent line is y=(1/2)x+4.5 or y=0.5x+4.5
And y=h(x)
So, h(x)=0.5x+4.5
Calculate h(-1), here x=-1:
h(x)=0.5x+4.5
h(-1)=(0.5*-1)+4.5

h(-1)=4
Calculate h'(-1), x=-1:

The total surface area of the prism is 217 square inches.
In geometry, a prism is a polyhedron with n sides made of polygons, a second base that is a translation of the first base, and n additional faces that must all be parallelograms and connect the effective distribution of the two bases.
The bases are translated into all cross-sections that are parallel to them.A solid object's surface area is a measurement of the overall space that the object's surface takes up.The base is a square with area = 49 square inches
Length of 1 side = √49 = 7 inches
Area of the triangular sides is given by the formula (1/2) × base × height
Area of each side
= (1/2) × base × height
= (1/2) × 7 × 12
= 42 square inches.
Total surface area
