<u>650 cannonballs
</u>
Explanation step by step:
upper layer = 1 ^ 2
second layer = 2 ^ 2
third layer = 3 ^ 2
layer 12 is 12 ^ 2
<u>The formula is:
</u>
<u>n * (n + 1) * (2n + 1) / 6
</u>
<u>n = 12
</u>
<u>12 (12 + 1) (2 * 12 + 1) / 6
</u>
<u>12 * 13 * 25/6 =
</u>
<u>650

There are 650 cannonballs in this pyramid.
Hi! I don’t know what any of this means but I hope you have an amazing day and I hope god/allah/etc. blesses you :)
sorry I couldn’t answer
Answer:
F. 5:4
Step-by-step explanation:
Solve for a and c to find the ratio of a to c:
- 2a = 3b
- a = 3/2(b)
- 6b = 5c
- c = 6/5(b)
Now, we can use the value of a and c to find the ratio of a to c:
- (3/2(b))/(6/5(b))
- 3b/2 × 5/6b
- 15b/12b
- 5/4
F. 5:4 is the correct answer
# of numbers between 1 & 103: 102
Half of that would be even numbers. So, 51 even numbers.
Between 4 and x, there are 102 numbers. 4+102=106. 4+106=x. 106=x
