Answer:
76
Step-by-step explanation:
median is the number in the very center of the list of numbers in order:
64, 72, 72, 80, 85, 89
to find the one in the middle we take away the numbers from both ends:
72, 72, 80, 85
72, 80
since there are two numbers in the middle we’ll find the average
(72+80)/2
152/2

Answer:
Isosceles
Step-by-step explanation:
Answer:
45 km/h
Step-by-step explanation:
In the first part of the trip, he already covered 30 km so we can subtract that from the total distance
45 - 30 = 15
This means he has 15 km to go
He also took an hour, or 60 minutes, to get to school. We subtract the time spent of the first part and time spent talking to a friend from the 60 minutes
60 - 35 = 25
25 - 5 = 20
He took 20 minutes to cover the second part of the journey
Speed = distance/time
15/20 = 0.75
He covered 0.75 km per MINUTE
to find it in km/h, we just multiply the number by 60
0.75 x 60 = 45
Answer:
A
Step-by-step explanation:
Consider the parent function 
The graph of this function is represented as red graph in attached diagram.
Now consider the function 
Remind main translations of the graph of the function 
- translation a units to the right;
- translation a units to the left;
- translation a units up;
- translation a units down.
In your case, the graph of the function 
is translated graph of the function 
2 units to the left (blue graph). So, correct answer is option A.
Answer:
n= 27
Step-by-step explanation:
To solve first subtract the 90-degree angle:
180-90= 90
Then, convert into an equation:
3n+9= 90
Subtract 9 from both sides:
3n=81
Then divide by 3:
n= 27
Hope this helps!
