Answer:
5/6 miles
Step-by-step explanation:
Matthews travels 2.5 miles → this is 3 times the distance that Jennifer travels
Jennifer travels 2.5 / 3 miles = 5/6 miles
because,
2.5 = 2 and 1/2 = 5/2
(5/2) ÷ 3 = (5/2) *(1/3) = 5*1/ 2*3 = 5/6
<u>650 cannonballs
</u>
Explanation step by step:
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
</u>
<u>There are 650 cannonballs in this pyramid.</u>
