How many hours? 1 hour 45 minutes of 145 hours lol?
Answer:
A. W
Step-by-step explanation:
The table in which each x-value is related to exactly one y-value is the table that represents a function.
Form the tables given, in table W, every x-value (input) has exactly one y-value (output) that is related to it.
Answer:
14 miles.
Step-by-step explanation:
Let the distance traveled from home to destination = x miles.
Speed while going to friend's house = 35 miles per hour.
Speed while coming back = 40 miles per hour.
Total Time taken for the journey = 45 minutes = 0.75 hours.
Let the time taken while going to friend's house = y hours.
Therefore, the time taken while going to friend's house = (0.75 - y) hours.
To find x and y, model the speeds of both the journeys.
Speed while going to friend's house = Distance/Time.
35 = x/y.
x = 35y (Equation 1).
Speed while coming back = Distance/Time.
40 = x/(0.75 - y).
x = 40(0.75 - y) (Equation 2).
Since x = x, therefore:
35y = 30 - 40y.
75y = 30.
y = 30/75.
y = 0.4 hours.
Put y = 0.4 hours in Equation 1:
x = 35y.
x = 35(0.4).
x = 14.
Therefore, the distance between my friend's house and my house is 14 miles!!!
In order to calculate the mean (average) you add up all the numbers and divide the total by how many numbers there are.
The sum of the data set is 468.
There are 5 numbers in the set.
468 divided by 5 is 93.6.
The answer is already to the nearest tenth, so the mean is 93.6.
