The average has to be at least 120 and at most 130
To calculate the average we need the sum of all values divided by the number of values, in this case, three (135, 145 and the third result).
120 ≤ (135 + 145 + n)/3 ≤ 130
In inequalities like this, what we change in one side, must be changed in the othe rside as well.
360 ≤ 280 + n ≤ 390
80 ≤ n ≤ 110
Answer:
addition I hope this is right
Answer:
x=-17
Step-by-step explanation:
subtract 6 from each side and simplify and you'll get -17
Answer:
Step-by-step explanation:
The area of a sector with measure 
in degrees is given by 
, where 
is the radius of the sector.
What we're given:
Solving, we get:
*Notes:
- units should be in square meters (area)
- the problem does not say whether to round or leave answers in term of pi, so you may need to adjust the answer depending on what your teacher specifically wants
