In this question, 10 people average running distance is 2.7miles. Then the sum of their running distance would be: 10 people * 2.7 miles/people= 27 miles.
The group then divided into 2, 4 people with 3 miles average and 6 people with unknown average. Since the people are same like the 10 people group, their total running distance would be the same. The calculation would be:
total distance = group1 * average1 + group2 * average2
27 miles= 4 people * 3 miles/people + 6 people* average2
6 people * average2 = 27 miles -12 miles = 15 miles
average2= 15 miles/6people= 2.5 miles/people
It is proportional because the relationship between gallons of gas and distance is constant and linear. The rate is 32 miles per gallon. You can also call 32 the slope of this linear relationship.
Answer:
14th term of geometric sequence 7, 28, 112 is 469762048
Step-by-step explanation:
Geometric sequence : 7, 28, 112, .....
First term = a = 7
Common ratio = r =
Common ratio = r =
Formula of nth term =
Substitute n = 14
So,
Hence the 14th term of geometric sequence 7, 28, 112 is 469762048
Answer:
Total is 20 coins
Step-by-step explanation:
