I) 4 Gallons
II) $77
Step-by-step explanation:
30km 1 gallon
420km ?
420 ÷ 30 = 14
? = 40
So, 4 gallons more will be needed to complete the journey.
1 gallon $5.50
14 gallon $?
14 x $5.50 = $77
The cost of the petrol is $77
According to the given table, the following statements are true.
Statement 1 is true : The car makes a complete revolution in 12 s.
Statement 2 is true: The radius of the Ferris wheel is 25 yards.
The maximum height is 55 yards and the minimum height is 5 yards. So, the radius will be : yards.
Using an infinite geometric sequence, it is found that the total distance that the ball travels is of 180 feet.
<h3>What is a geometric sequence?</h3>
A geometric sequence is a sequence in which the result of the division of consecutive terms is always the same, called common ratio q.
The nth term of a geometric sequence is given by:
In which is the first term.
Considering q < 1, the sum of an infinite sequence is given by:
In this problem, the first term and the common ratio are given by:
Hence the total distance traveled in feet is given by:

Answer:
400
Step-by-step explanation:
sqrt(160000)=sqrt(16)*sqrt(10000)=4*100
The answer is k-2/9 because it says that k is decreased which means u substrate and then it's says the quotient of 2 and 9 which means that u divide so then u get 2/9
