Answer: The amount of cars they can expect to wash is 27, 792 in 2010.
Step-by-step explanation:
This problem asks us to calculate the potential growth of the business through a period. One of the ways to solve this problem is to use the formula for exponential growth to determine the number of cars they expect to wash in 2010.
[tex]f(x) = a(1 + r) ^x\\f(x) = 19, 300 (1+0.20)^2\\f(x) = 19, 300 (1.20)^2\\f(x) = 27, 792[/tex]
a = initial growth - 19, 300
r = growth rate - 0.20
x = time (years) - 2 years
We get 27, 792 as our final answer.
Suppose the length of a diagonal of a square increases from 16 cm to 16.1 cm. What would the change in the area of the square be
The change in area will be such that it will increase by 1.605 or 1.25%.
What is a square?A square is a geometrical figure in which we have four sides each side must be equal and the angle between two adjacent sides must be 90 degrees.
Area of square = Side²
The perimeter of the square = 4× side
The area of a square with diagonal x is given as x²/2.
Area with diagonal 16 cm ⇒ 16²/2 = 128 cm²
Area with diagonal 16.1 cm ⇒ 16.1²/2 = 129.605 cm²
Change of area = 129.605 - 128 = 1.605 cm².
Percentage change = 1.605/128 x 100 = 1.25%.
Hence "The change in area will be such that it will increase by 1.605 or 1.25%".

How many packages of diapers can you buy with $36 when on package costs $9?
Based on the calculations, the number of diapers which can be bought with $36 is equal to $4.
Given the following data:
Cost of diaper = $9.Amount for packages = $36.How to calculate the number of diapers?In order to determine the number of diapers that can be bought with $36, we would set up a direct proportion equation as follows:
$9 = 1 diaper
$36 = X diapers.
Cross-multiplying, we have:
9X = 1 × 36
9X = 36
X = 36/9
X = $4.

the distance from the earth to the Sun is approximately 9.3×10^7 miles. if light travels 1.2×10^7 miles in 1 minute, how many minutes does it take the light from the sun to reach the earth ?
It takes approximately 12.47 minutes for light from the Sun to reach the Earth.
Explanation:To find out how many minutes it takes for light from the Sun to reach the Earth, we can divide the distance from the Earth to the Sun by the distance light travels in 1 minute.
First, let's convert the distance from miles to kilometers. 1 mile is approximately 1.60934 kilometers, so the distance from the Earth to the Sun is approximately 1.496 × 108 kilometers.
Now, we divide this distance by the distance light travels in 1 minute: 1.496 × 108 kilometers / 1.2 × 107 kilometers per minute = 12.47 minutes.
Therefore, it takes approximately 12.47 minutes for light from the Sun to reach the Earth.

Find the standard deviation for each data set. Which set is more variable?
Answer:
Second set.
Step-by-step explanation:
I put the formula of standart deviation in the image below.
x is each data of the list
μ is the data average
N is the amount of elements.
So, for the first list we have:
μ= [tex]\frac{28995+37534+31361+27087+20966+37741}{6}= \frac{183684}{6}=30614[/tex]

= [tex]\sqrt{ 34563888.6667 }[/tex]
= 5879.1061.
For the other list of elements:
μ= [tex]\frac{72964+70763+101510+62161+66625+54339}{6}= \frac{428362}{6}=71393.66[/tex]

The arcade has 3 pinball machines and 5 video games. If a person wants to play one pinball machine and one video game, how many different combinations of games could that person play?
The number of possible combinations of playing one pinball game and one video game, given there are 3 pinball machines and 5 video games available, is 15.
Explanation:The subject of this question is combinatorics, a part of Mathematics that deals with combination and arrangement of objects. The question in essence is asking about the number of combinations one can play on a pinball machine and a video game in an arcade.
In the given context, there are 3 pinball machines and 5 video games. If a person wants to play one of each (one pinball game and one video game), we can calculate the number of combinations by simply multiplying the number of options for each game. That is, 3 pinball machines multiplied by 5 video games equals 15 different combinations.
So, there are 15 different combinations of games a person can play when selecting one pinball and one video game from the given sets.

The shanghai maglev train is one of the fastest trains in the world, traveling about 2144 miles in 8 hours. How many miles does it travel in one hour? The distance between columbus ohio and new york city is about 560 miles.how many hours would it take the train to travel between the cities
Answer:
The train travels 268 miles in 1 hour. It would take 2.0896 hours to travel between the cities.
Step-by-step explanation:
Consider the provided information.
The shanghai maglev traveling about 2144 miles in 8 hours.
This can be written as:
2144 miles = 8 hours
Divide both sides by 8.
2144/8 miles = 8/8 hours
268 miles = 1 hours
Thus, the train travels 268 miles in 1 hour.
The distance between Columbus Ohio and new York city is about 560 miles. We need to find how many hours would it take the train to travel between the cities.
268 miles = 1 hours
Divide both the sides by 268.
1 miles = 1/268 hours
Now multiply both sides by 560.
560 miles = 560/268 hours
560 miles = 2.0896 hours
Hence, it would take 2.0896 hours to travel between the cities.
