An automated car wash can wash 30 cars in 5 hours. How long would it take to wash 120 cars? A. 15 h B. 20 h C. 25 h D. 30 h
Answers
An automated car wash can wash 120 carsin 20 hours.
What is expression?
In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.
Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.
Given is that an automated car wash can wash 30 cars in 5 hours.
Now, an automated car wash can wash 30 cars in 5 hours.
Then, 1 car can be washed in (5/30) hours.
So, 120 cars will take (5/30 x 120) hours
(5/30 x 120)
5 x 4
20 hours
Therefore, an automated car wash can wash 120 carsin 20 hours.

So, divide 120 by 6
120 / 6 = 20 hours
Hope this helped!

We know that when: t=0, C(t)=8.
With this data, the expression below can be produced...
8=ab⁰
Now since b⁰=1, we've discovered that a=8.
----------
Furthermore, we also know that when: t=1, C(t)=24. Since we discovered that a=8, we can produce the expression below...
24=8*b¹
This means that:
8b=24
Therefore: b=24/8=3.
If a=8 and b=3...
C(t)=8*(3^t)
Answer:
C(t)=8*(3^t)
0,8
so
8=ab^0
8=a1
8=a
we also have
1,24 so
24=8b^1
24=8b
divide 8
3=b
therefor the eqution is

Option C) is correct.
Step-by-step explanation:
One to one function can be checked by using horizontal line test and vertical line test.
A)
the graph of this function ia attached below named as Graph 1.
The above function did not pass the horizontal line test therefore it is not a one to one function.
the graph of this function is attached below named as Graph 2.
The above function did not pass the vertical line test therefore it is not a one to one function.
the graph of this function is attached below named as Graph 3.
The above function pass the horizontal line test as well as vertical line test and therefore this function is one to one function.
the graph of this function ia attached below named as Graph 4.
The above function is a floor function and fail the vertical line test.
Therefore, correct answer is option C).
For more information, refer the link given below
check the picture below.
bearing in mind that a one-to-one function must pass the horizontal line test as well as the vertical line test.
now, |x| is the graph of a letter V more or less, and that'd fail the horizontal line test.
the first piecewise function, has say 4 : x < 0, namely for all values before 0, "y" is a steady constant of 4, that will be a horizontal line and will definitely fail the vertical line test.
[[x]] is pretty much the "floor function", and you can do a quick google search on it, or do it in your calculator, it should have a floor function, but that one will definitely fail the vertical line test as well.

For example, we have 3/4 and 7/8.
3/4 misses 1/4.
7/8 misses 1/8.
According to the rule, we choose 7/8 as a larger one because it "misses" less then 3/4. (1/8 < 1/4)
