1. Find the distance Sonya traveled:
20-8=12
12x1000feet=12000feet
2. Find the time it took Sonya to travel this distance:
Starting time: 3:10
Finish time: 3:14
Difference= 4min
3. Use the speed formula: S=D/T
S=12000feet/4min
S=3000feet/min
Answer:
1:100 and 1:14
Step-by-step explanation:
Substituting a, ( y ) for the given value, which is 8, we proceed to say that:
8y - 4, would be 8 (8) - 4,
which would be 64 - 4 = 60
The answer is: 60
Answer: 13
Step-by-step explanation:
First, we have to arrange the numbers in either ascending or descending order.
12,11,13,12,15,16, and 14 hours will then be: 11, 12, 12, 13, 14, 15 and 16.
The median will be gotten using the formula: = (n + 1) / 2
Since there are 7 numbers this will be:
= (n + 1) / 2
= (7 + 1) / 2
= 8/2
= 4th number
Since 13 is the 4th number, it's the median
The answer will be (x-2) (x+2) (x^2+4)
