Well a fraction is set up as a unit rate or a ratio along with the unit rate it is a ratio
Answer: 90 visitors per hour
Explanation: "Per hour" means in 1 hour, so we can rewrite the given statement using fractions as <em>450 visitors/5 hours = __visitors/1 hour</em>.
To find out what goes in the bank, notice that we
have a 1 in the denominator of our second fraction.
So we want to find a fraction that is equivalent
to 450/5 that has a 1 in the denominator.
If we divide the numerator and denominator of 450/5 by 5,
we get the equivalent fraction 90/1 or <em>90 visitors/1 hour</em>.
So now we have <em>90 visitors/1 hour = __visitors/1 hour</em>.
So a 90 must go in the blank.
This means that the museum sees 90 visitors per hour.
Answer:
Step-by-step explanation:
The final price is $135 , because
.10 × 150 = 15
150 - 15 = 135
The limit is the value of the function when you approach the closest possible to the x value without getting to that x value.
The closed point (2,1) is not used to calculate the limit. The closed point (2,1) represents the value of the function at x = 1, but the limit is not the value of the function.
Use the horizontal line that comes from the left and ends at the open point (2,3) to find the limit of f(x) when x approaches to 2 from the left.
That limit is 3, because you can get as close as you want to 3 when you approach x = 2 from the left.
Use the horizontal line that starts at the open point (2-2) and goes to the right, to find the limit of f(x) when x approached to 2 from the right.
That limit is -2 because you can get as close to -2 when you approach x = 2 from the right.
It is important that you know that the definition of limits do not include the value of the function at the point where you want to state the limit.
This result, limit of f(x) when x approaches 2 from the left = 3 and limit of f(x) when x approaches 2 from the right = -2, means that the limit of the function when x approaches 2 does not exist.
The limit exists if and only if the two lateral limits exists and are equal.
