what does break-even mean in Maths Lit
Answers
Answer:
Break-even point is where the business is at an activity level (doing business) at which total cost = total sales, i.e. you have made enough income to cover the costs.
Answer:
The break-even point is the point at which total cost and total revenue are equal, i.e. "even". There is no net loss or gain, and one has "broken even"
Step-by-step explanation:
for example you want to run a hat business and it costs 10 dollars to produce each hat and a set price of 5000 dollars for the shop. and you sell each hat for 20 dollars. You would need to sell x number of hats in order to make what you spent. thats what break-even is. So basically you made back everything you spent and can bein to profit if that makes sense.
The perimeter of a rectangle is 90 feet, and the length is 32 feet. What is the width of the rectangle?
A. 26 feet
B. 13 feet
C. 58 feet
D. 15 feet
Answers
2 x (length + width) = perimeter = 32 ft
⇒ length = 16ft - width [1]
length x width = area = 48 sq ft
Using [1] above:
⇒ (16ft - width) x width = 48 sq ft
multiplying out and rearranging:
⇒ width2 - 16 x width + 48 = 0
factorizing:
⇒ (width - 4)x(width - 12) = 0
Thus width = 4 or 12, so using [1] above:
⇒ width = 4ft, length = 16 - 4 = 12ft
or width = 12ft, length = 16 - 12 = 4ft
Convention is that the length is larger than the width, thus rectangle is 12ft long by 4 ft wide.
Answer:
15 ft

Suppose the population of a town is 17,400 and is growing 2% each year.
Predict the population after 9 years.
Answers
Answer: 20,532
Step-by-step explanation:
17,400(.02)=348
348(9)=3132
17,400+3132=20,532
Answer:
Step-by-step explanation:
This is an exponential growth function of the form:
[tex]y=ab^x[/tex] where a is the initial population and b is the growth rate. This could also be written as
[tex]y=a(1+r)^x[/tex] which is a bit more accurate. We'll use that one. r is the percent growth: 2% for us.
Filling in the formula:
[tex]y=17400(1+.02)^x[/tex] and then simplifying:
[tex]y=17400(1.02)^x[/tex]
That's the model for this population. Filling in any number of years for x will give you the population y. Our time is 9 years:
[tex]y=17400(1.02)^9[/tex]
Take care of the exponents first, giving us:
[tex]y=17400(1.195092569)[/tex] and then multiply to get
y = 20,794.6 or 20,794 people (since you can't have 6/10 of a person)

A or [tex]\frac{\sqrt{6} }{2}[/tex]
Step-by-step explanation:
*note- this method only works because the denominator values are being multiplied, if they were being added then there are extra steps to keep in mind but for now this is simple*
Start by dividing the root 12 in the numerator by the root 2 in the denominator
[tex]\frac{\sqrt{12} }{\sqrt{2} }=\sqrt{6}[/tex]
Then we simply substitute back in the 2 (from the denominator) that we ignored for a second to get our answer
[tex]\frac{\sqrt{6} }{2}[/tex]
*note- if you are allowed to use a calculator then you could also plug in your values to check each answer option but since this question isn't too complicated there should be no need to do so unless you forget how to solve it algebraically*

Step-by-step explanation:
Given the five number summary which are all displayed on a box and whisker plot :
Maximum = 48
Minimum = 27
Median = 36
Upper Quartile = 45
Lower quartile = 32
Maximum and minimum values are displayed by the whiskers :
Starting point of whisker = minimum value
End point of whisker = maximum value
The quartiles are displayed by the box :
Starting point of the box = lower quartile
End point of the box = upper quartile
Line in between the box = Median

Step-by-step explanation:
√18 = √(2x9) = 3√2. so they pulled the 2 out of the square root incorrectly.

What is the Sine Rule?The Law of Sines (also called the Sine Rule) is defined as it relates all three sides of a triangle with an angle of a triangle.
Triangle is a basic polygonal shape of a triangle that has three sides and three interior angles. It is one of the fundamental shapes in geometry.
As per the given question, the given data as:
A = 63
B = 56
C = 61 (because these angles should add up to 180)
c = 1/2
We know that the Sine Rule,
sin 63 / a = sin 61 / .5
a = 0.51 miles
sin 56 / b = sin 61 / .5
b = 0.47 miles
Therefore, the length 0.51 miles and 0.47 miles are the distances from each observer to the sailboat.
