Answer:
125
Step-by-step explanation:
120 - 90 = 25 x 5 = 125
? = 2. Thats the only one i got that equals 8xy^2. Not sure if its right tho.
12 oz = 1.15
24 oz = 2.79
Let's see if 2x12oz is equal, less, or more than the 24oz.
1.15 x 2 = 2.30
2.30<2.79
The 12 oz is a better buy.
<span>here is some introduction.
A common
language is needed in order to communicate mathematical ideas clearly and
efficiently. Exponential notation is one example. It was
developed to write repeated multiplication more efficiently. For example, growth
occurs in living organisms by the division of cells. One type of cell divides 2
times in an hour. So in 12 hours, the cell will divide 2 • 2 • 2 • 2 • 2 • 2 • 2
• 2 • 2 • 2 • 2 • 2 times. This can be written more efficiently as
212.</span>
theoretical probability is a coin will land on heads 50% of the time
50% of 100 = 50
since it only landed on heads 38 times, this was less than the theoretical probability of 50
