A square has one side measuring 5 feet. What is its area?
25 square feet.
A = L x W, so 25 = 5 x 5.
Solve for x:
10 = 5x + 15
x = -1
If there are 6 chickens and 3 tacos, what is the ratio of tacos to chickens in simplest form?
1:2
A bag has 3 red marbles, 2 blue, and 4 yellow. What is the fractional probability of pulling a red marble?
1/3.
The bag has 9 marbles in total, 3 are red, 3/9 is 1/3.
Solve for x:
-9x + 3x - 4 = 20
x = -4
Simplify:
16:4
4:1
Solve for q:
q/10 - 15 = 15
q = 300
Solve for x to make these proportional:
5/6 = x/36
x = 30
Suppose out of a class of 15, 3 kids obtain a perfect score on an exam. What is the percentage of kids who obtained a perfect score?
20 percent!
15/3 = .2 which is equivalent to 20%.
Solve for y:
2(5 + y/11) = 30
y = 110
How many numbers are there between 0 and 1?
Infinite.
0.1, 0.001, 0.00001, 0.000001... and so on.
Solve for f:
10(-11f + (-5)) = 1380
f = -13
