Answer:
- The value of z to balance the hanger is 2.75.
Step-by-step explanation:
<u>We know that:</u>
- 11 = 4z (In balanced form)
To balance the hanger, we must find the value of z such that if z is multiplied by 4, it will equal 11.
<u>Work:</u>
- 11 = 4z
- => z = 11/4
- => <u>z = 2.75</u>
Hence, the value of z to balance the hanger is 2.75.
The correct answer is, B. 1/5
Hope this helps!
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.
