Answer:
The 50th term is 147
Step-by-step explanation:
The nth term of an AP can be find as:
Where, a is the first term, d is the common difference, n is the number of term and is the nth term.
Now consider the provided AP: 0,3,6,9...
Here, the first term is 0, common difference is 3 and n is 50.
Substitute a = 0, d = 3 and n =50 in above formula.
Hence, the 50th term is 147
Answer: The Van needs 18 gallons of gas to travel 360 miles.
Step-by-step explanation: Given that a Van travels 300 miles on 15 gallons of gas.
We are to find the number of gallons that the Van needs to travel 360 miles.
We will be using the UNITARY method to solve the given problem.
Number of gallons needed to travel 300 miles = 15.
So, number of gallons needed to travel 1 mile will be
Therefore, the number of gallons needed to travel 360 miles is given by
Thus, the Van needs 18 gallons of gas to travel 360 miles.
Amount of gas required to travel is .
Further explanation:
The word problems can be solved from the unitary method.
The unitary method is a method in which we have to first find the value of a single unit then further find the required value by multiplying the single unit value.
Given:
A van travelled on of gas.
Calculation:
Step 1:
First we have to find the number of gallons in one mile.
It is given that the number of gallons needed to travel is equal to .
Use the unitary method to calculate the number of gallons in one mile.
It is calculated as follows:
Step 2:
Now, we have to calculate the number of gallons needed to travel in .
Use the unitary method to calculate the required value by multiplying the single unit value.
The number of gallons in one mile is .
Therefore, the number of gallons in is calculated as follow:
Thus, the Van requires of gas to travel .

Answer: You spent 31.39 minutes reading.
Step-by-step explanation:
Hi, to answer this question we have to analyze the information given ( you write the numbers doubled, 9.759.75 is 9.75)
If you read 9.759.75 pages in your science book and it takes you 1.2 minutes to read each page, we simply have to multiply the numbers of pages by the time spent for each page.
9.75 pages x 1.21 minutes = 11.79 minutes
We do the same thing for the play:
24.5 pages x 0.8minutes = 19.6 minutes
Finally, we sum both results:
11.79 m + 19.6 m =31.39
You spent 31.39 minutes reading.
