◉ How many total degrees in a parallelogram? Hint: parallelogram =
2 triangles. Answer: 360 degrees
◉ Range. Answer: The greatest value minus the smallest value
◉ SSAT Special Functions (weird symbol problems). Answer: Don't
panic! They will define the function for you. All you have to do is
plug in the numbers for the variables.
Ex: a £ b = a + 5b
What is the value of 6 £ 1 ?
6 £ 1 = 6 + (5)(1)
6£1=6+5
6 £ 1 = 11
◉ Combined average problems. Answer: Break into two separate
average equations before combining to solve.
, Ex: The average test score for 5 girls is 90. The average test score for
10 boys is 85. What is the average test score of all the students (boys
and girls)?
GIRLS
90 = x / 5
(90)(5) = x
450 = x
BOYS
85 = x / 10
(85)(10) = x
850 = x
Now, combine into one big average problem!
Group average = (850 + 450) / 10 + 5
= 86.7
Group average = 86.7
