The ones ticked are correct
Given
6 + 18 + 54 + 162 + 486
There is a common ratio r between consecutive terms, that is
18 ÷ 6 = 54 ÷ 18 = 162 ÷ 54 = 486 ÷ 162 = 3
This indicates the series is geometric with explicit formula
= a
where a is the first term and r the common ratio
Here a = 6 and r = 3, thus explicit formula is
= 6
The series in summation form with 5 terms in the series is
∑ 6 for k = 1 to 5
Sum = 6 + 18 + 54 + 162 + 486 = 726
Answer:
Yamal can move the ice to 82 km in approximately <u>15 hrs</u>.
Step-by-step explanation:
Given:
Speed = 5.5 km/hr
Distance = 82 km
Let time be represented as 'x'.
We need to find the number of hours required to travel 82 km.
We know that Distance can be calculated by the product of Speed and time.
Framing above sentence in equation form we get;
Distance = Speed × Time
Substituting the given value we get;
Hence The expression for number of hours is
Solving the equation to find the value of x we get;
Hence Yamal can move the ice to 82 km in approximately <u>15 hrs</u>.
