Answer:
you have an odd number, divide by 2 and round up to get the position of the median number.
Step-by-step explanation:
you have an even number, divide by 2. Go to the number in that position and average it with the number in the next higher position to get the median.
Answer:
( since they're similar, they are proportional to each other)
1 (7.2) = h (1.6) (set the two up as a proportion and then cross multiply)
7.2 = 1.6h (divide both sides by 1.6)
h = 4.5 m (this is the answer)
Step-by-step explanation:
Y = 18(1.15)x is the answer
After one year
18×(1.15)=20.7
After two years
18×(1.15)^(2)=23.81
Answer:
This is one of a variety of "subtraction solutions"--basically a different way to subtract by breaking numbers down into 10-digit chunks. It's not especially helpful for small subtraction problems, but as math gets more complicated, this method will come in handy.
Step-by-step explanation:
Here's an example: Jim had a bag of 15 jelly beans. He eats 8. How many jelly beans does he have left? <u>Take apart the number to make a 10. Then subtract.</u>
Here, you need to "take apart" the 8 to make your 15 jelly beans 10, then you subtract the remainder of 8 to get your solution. In other words,
--"take apart" 8 into 5 and 3 (because you're going to need a 5 to make 15 into 10). 15 minus 5 equals 10. HOORAY! You have your 10. Now, subtract the remaining 3. 10 minus 3 equals 7. Huzzah--your final answer!
On paper, the problem looks like this:
<u>15 - 8 (</u><u>5, 3</u><u>) = ?</u>
15 - 5 = 10
10 - 3 = 7
So...15 - 8 = 7
