Hello!
Multiply the amount of bags Mr. Eaton bought by the amount of pounds each bag weighs:
15 * 45 = 675
The total weight of the topsoil Mr. Eaton bought is 675 pounds.
Since each angle of the hexagon is a 30 degree rotation just count the letters as you move and multiply by 30.
1. 120 degrees
2. 30 degrees
3. 30 degrees
There will be 23 layers of brick, because 7500/321 = 23 with 117 leftover.
Total no. of outcomes when two dice are rolled = 36
No. of outcome when 6 will be on both dice = 1
Probability of rolling two 6's = 1/36
Hope this helps!
