To calculate the average, we will use the following rule:
average = sum of scores / number of scores
sum of scores = 85+72+89+90 = 336
number of scores = 4
average = 336/4 = 84%
Answer:
m < b = 70, m < c = 110 and m < d = 70 degrees.
Step-by-step explanation:
The opposite angle a ( angle c) = a = 110 degrees (Property of a parallelogram).
The angle on the same line as a ( that is angle b) = 180 - 110 = 70 degrees.
(Property of a parallelogram).
Finally angle d which is opposite angle b = 70 degrees.
The largest square you can make using 40 tiles, would be 100
Answer:
-4 and 9
Step-by-step explanation:
x² - 36 = 5x
= x² - 5x - 36
= (x + 4) (x - 9)
x + 4 = 0
x = -4
x - 9 = 0
x = 9
