The range is the distance between the largest and smallest numbers in a set of data (Largest number - smallest number = range)
Here we know the smallest number (20) but the largest number is at some point between 60 and 80.
To find the increment of each line in-between 60 and 80:
80-60 = 20
20/5 = 4
So the values will be 60, 64, 68, 72, 76, 80
Therefore the largest value is at the 76 mark
Now to find range by subtracting the smallest number from the largest number:
76-20 = 56
The range is 56
Answer:
[?] = 108
Step-by-step explanation:
is 3/4 of a whole revolution:
so the area of the sector is 3/4 of the area of the entire circle.
Area of a circle: 
Area of the sector: 
First one is 42
second is 24
Third is 12
If said number is x, that means that twice (2 times) a number and 2x-7=13. Adding 7 to both sides, we get 2x=20 and by dividing both sides by 2 we get x=10. For 2, we see that the sum of a number and 6 is first priority, so we have (x+6)*7=-43. Dividing both sides by 7, we get x+6=-43/7. After that, we subtract both sides by 6 to get -43/7-6=x
