Answer:
33.75.
Step-by-step explanation:
The mean = sum of the numbers / the number count
= (34 + 31 + 32 + 38) / 4
= 135 / 4
= 33.75.
Answer:
30.08 liters of gas.
Step-by-step explanation:
Given:
Paul's car holds at most 17 gallons of gas.
Now it has 9 gallons.
Question asked:
Explain how to find the amount of gas he needs in liters.
Solution:
Capacity of Paul's car = 17 gallons of gas.
Now it has = 9 gallons of gas.
He need more = 17 - 9 = 8 gallons of gas.
Now, we have to convert it into liters:-
As we know:
Given:
1 gallon = 4 quarts ( Unitary method )
8 gallons = 
Now, we will convert it into liters:- ( Unitary method )
1 quart = 0.94 liters
32 quart = 
Thus, he needs 30.08 liters of gas.
Determine how much of the job they have finished by calculating:
2/4 + 2/6 = 1/2 + 1/3 = 5/6 of the job has been done.
So, they have 1/6 of the job to go.
Then we write the following fractional equation:
t/4 + t/6 = 1/6
Multiply all by 12 (the LCD) and get
3t + 2t = 2
5t = 2
t = 2/5 hour = 24 minutes.

e=3n
where e =edges and n= number of sides
n= e/3
Answer:
The area of the circle is 19.625.
Step-by-step explanation:
- To find the area of a circle, you use the formula A=πr², so you need the radius. The radius is half of the diameter, so half of 5 is 2.5.
- Next, you just plug the numbers into the formula (I used 3.14 for pi). A=(3.14)(2.5²).
- A=(3.14)(6.25)
- A=19.625
- Round to your liking/whatever the question asks for and add the units the question asks for as well. If there aren't any offered in the question, just use units squared if you have to give any.
