Good job!
The third angle is equal to 52 degrees.
What is the value of 6 in the number 256,945?
Nice work!
The value is 6 000.
3 to the power of 2 * 5 = x
What is x worth
9 x 5 = 45
The answer is 45
What is the probability of rolling an even number on a 6 face die?
6 numbers
2, 4, 6
= 3/6
= 1/2
0.4 + 0.04 + 0.004
0.444
A) Define a supplementry angle
B) Define a complementry angle
Awesome work!
A) All the angles of a supplementry angle have a sum of 180 degrees.
B) All the angles of a complementy angle have a sum of 90 degrees.
What is the word form and expanded form of the number 534,903?
Good guess!
The word form is five hundred thirty-four thousand nine hundred three.
The expanded form is 500 000+30 000 +4000+900+3.
20% x y = 5
What is the value of y?
100 / 20 = 5.
5 x 5 = 25
The value of y is 25

(hint : move decimal point)
To get to 180˚ in an isosceles triangle, one angle is 54˚, what are the other two angles?
180 - 54 = 126. 126 / 2 = 63.
The answer is 63 (two angles = same)
Name all the prime numbers up to 20.
You guys are so smart!
2,3,5,7,11,13,17,19
Y = 13.
10y - 50 = ?
What is the answer?
13 x 10 = 130.
130 - 50 = 80
The answer is 80
There are 5 cards, numbered 1,2,3,4, and 5 in a box. Two cards are selected randomly without replacement from the box. What is the probability that 1 is the largest number selected?
the answer is 0/5
out of all the numbers 1 is the smallest (impossible)
express this fraction as a decimal = 80/1000
the answer is 0.08

What is the total sum of the area of both trapezoids?
You are on a roll!
The total sum of their area is 46.5
(15 x 6) x 2
180
X is 6.
5x + 20 / 5 = ?
What is the answer?
30 + 20 / 5
50 / 5
The answer is 10
from a well shuffled deck of 52 cards, what is the probability of getting a king?
4 kings and 52 cards.
= 4:52
= 2:26
= 1:13
3.6 / 0.04 x 2
90 x 2 = 180
The angles in this certain parallelogram adds up to 360˚.
Angle A is 137˚. B is 90˚. C, the EXTERIOR angle is 98˚ but you must figure out the interior angle. With all these added up, what is D worth.
(Hint: Subtraction)
180 - 98 = 82.
82 + 137 + 90 = 309
360 - 309 = 51.
ANGLE D IS WORTH 51.
Sahai goes to a grocery store and buys 3 jugs of milk that cost $4.55 each. Sahai pays with a $20 dollar bill. If Tiana the grocer only gets nickels back, how many nickels does she get as her change?
(Hint: change the decimal spots)
4.55 x 3 = 13.65
20 - 13.65 = 6.35
6.35 --> 635. 0.05 --> 5
635/5 = 127.
SAHAI GETS 127 NICKELS BACK.
x is 7, y is 9.
(6x * 3) + (5y * 2) = ?
What is the answer?
(42 x 3) + (45 x 2)
126 + 90
The answer is 216.
Suppose a standard fair 6-sided die is rolled twice. What is the probability that the two numbers that come up are both the same
1-1, 1-6
2-2 - 6
3-3 - 6
4-4 - 6
5-5 -6
6-6 - 6
= 6 x 6 = 36
6/36
= 1/6
