Shapes of You (Geometry)
Which of the following is NOT a polygon: triangle, square, octagon, circle
Circle
(Polygons must have at least three straight sides and angles)
Finn's grandma gave him $20 for his birthday. Finn owes Sebastian $33. How much money does Finn "really" have?
$ -13
($20 income = +20, $33 debt = -33, then 20 - 33 = -13)
Solve for x:
3x = 9
x = 3
(9 / 3 = 3)
What is the probability of rolling an even number on a standard, 6-sided die?
3/6 or 1/3
The location of a point is given using these two alphabetical lines
x- and y-axis
When dealing with positive and negative integers, what does it mean to have a "zero pair"? (You can explain in words, or give examples)
Examples: 1 + (-1) = 0, -5 + 5 = 0, etc.
Solve for y:
2y - 4 = 12
y = 8
(12 + 4 = 16, 16 / 2 = 8)
A package of M&Ms contains 8 red M&Ms, 6 green M&Ms, 5 brown M&Ms, 9 blue M&Ms, and 7 yellow M&Ms. What is the probability of the first M&M you pull out being yellow?
7/35 or 1/7
(8 + 6 + 5 + 9 + 7 = 35)
An angle with a measurement of 90 degrees is also know as what name?
Right angle
Solve the following: -18 + 30 + (-5) = ?
7
(-18 + 30 = 30 - 18, and 30 - 18 = 12; 12 + (-5) = 12 - 5, 12 - 5 = 7)
Solve for a:
5a + 11 = 56
a = 9
(56 - 11 = 45, 45 / 5 = 9)
An animal shelter has 25 dogs, 30 cats, 18 bunnies, and 22 lizards. If you were to adopt an random animal, what is the probability of getting a dog?
25/95 or 5/19
A rectangle has an area of 32 cm and a perimeter of 24 cm. What are the lengths of its sides?
8 and 4 cm
Solve the following: 52 + 13 - 73 = ?
-8
(-73 + 13 = - 60; -60 + 52 = -8)
Solve for b:
10b - 8 = 12
b = 2
(12 + 8 = 20, 20 / 10 = 2)
Describe how to find mean, median, and mode.
Mean = Average, find the sum of set, then divide by the number of items in the set)
Median = Arrange numbers from least to greatest and find the middle number
Mode = Find the number that occurs most in the data set)
A triangle has angles measuring 60 degrees and 80 degrees. What is the third angle?
40 degrees
(The angles in a triangle always add to 180 degrees, so 180 - 80 = 100, then 100 - 60 = 40)
Determine whether each type of multiplication problem results in a positive or negative answer.
POS. x POS. = ?
POS. x NEG. = ?
NEG. x NEG. = ?
POS. X POS. = POSITIVE
POS. x NEG. = NEGATIVE
NEG. x NEG. = POSITIVE
Solve for x:
12x - 62 = 82
x = 12
(82 + 62 = 144, 144 / 12 = 12)
Find the mean, median, and mode for the following data set:
8, 3, 0, 10, 7, 7, 2, 13, 4
Mean: 6
Median: 7
Mode: 7
(0, 2, 3, 4, 7, 7, 8, 10, 13)
