Volume of cylinder = πr²h
Volume = 3.14 x 4² x 20
Volume = 1,004.8 m³
When the tank is 60% full, the volume is:
0.6 x 1004.8
= 602.88 m³ of water
So since there are 2 placeholders, the answer are many, but we can make into slope intercept form to make it easier to solve (slope intercept form is y=mx+b)
15x-12y=60
15x-60-15y=0
15x-60=12y
12y=15x-60
divide both sides by 3
4y=5x-20
divide both sides by 4
y=5/4x-5
just put in values for x and get y so exg
(x,y)
0,-5
1,-15/4
2,-5/2
3,-5/4
4,0
and so on
= 9n + 63
generate the first few terms using the recursive equation
f(1) = 72
f(2) = 72 + 9 = 81
f(3) = 81 + 9 = 90
f(4) = 90 + 9 = 99
the sequence is 72, 81, 90, 99, .....
This is an arithmetic sequence whose n th term formula is
=
+ (n - 1 )d
where
is the first term and d the common difference
d = 99 - 90 = 90 - 81 = 81 - 72 = 9 and
= 72
= 72 + 9(n - 1) = 72 + 9n - 9 = 9n + 63 ← explicit formula
Answer:
The gasoline cost $411.47.
Step-by-step explanation:
This problem can be solved using rules of three.
The first step is finding how many gallons were used.
They travelled a total of 3982 miles. They averaged 24 miles per gallon of gasoline.
So
1 gallon = 24 miles
x gallons - 3982 miles
![24x = 3982](https://tex.z-dn.net/?f=24x%20%3D%203982)
![x = \frac{3982}{24}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B3982%7D%7B24%7D)
![x = 195.9](https://tex.z-dn.net/?f=x%20%3D%20195.9)
195.9 gallons were used.
How much did the gasoline cost is the price per gallon was $2.48?
Each gallon costs $2.48. 195.9 gallons were used. So
$2.48*195.9 = $411.47
The gasoline cost $411.47.
