If you start with 1 cheerleader in row A, then you'll have 3 cheerleaders in row B (add on 2), and then 5 cheerleaders for row C (add on another 2), etc etc.
Note how: 1+3+5 = 4+5 = 9 which is a perfect square. Also note that 36 is a perfect square.
Rule: The sum of the first positive n odd numbers is going to be equal to n^2. In the example of adding the first three odd numbers (1,3,5), we have n^2 = 3^2 = 9 as the sum
So as you can see, we'll have n = 6 rows because n^2 = 6^2 = 36 and
1+3+5+7+9+11 = 36
which is the sum of the first six positive odd numbers. So we'll have 1 cheerleader in row A, 3 in row B, 5 in row C, 7 in row D, 9 in row E, 11 in row F to have 6 rows total.
Answer:
The answer for 4.5 to multiply 3.5 is 15.75
Answer:
Y = MX
Step-by-step explanation:
If two quantities X and Y maintain a proportional relationship with each other, then we can write this as Y ∝ X.
Now, converting this relation into the equation we write Y = MX ........ (1), where M is a constant.
Now, from the above equation, we can say that the rate of change of Y with respect to the unit change of X is always constant.
Graphically. this equation represents the graph of a straight line with a constant slope and passing through the origin. (Answer)
