Answer:
Craig's collection increased by 20%.
Step-by-step explanation:
Original amount: 10
New amount: 12
To find the percent increase, we first need to find how much Craig's record collection increased by. To do this, subtract the old amount from the new amount:
12 - 10 = 2
The amount his collection increased by is 2. To find the per cent increase, divide 2 by the original amount of records:
Convert the decimal into a percentage:
0.20 * 100 = 20%
The percent increase of Craig's record collection is 20%.

Answer:
500%
Step-by-step explanation:
We find the volume of pyramid A
Pyramid A is a square pyramid with a base side length of 9 inches and a height of 10 inches.
Volume = a² h/3
Where a = 9 in
h = 10 in
Volume = 9² × 10/3
Volume = 270 cubic inches
Pyramid B has a volume of 1,350 cubic inches.
Step 2
We compare both volumes
Pyramid A : Pyramid B
270: 1350
= 270/ 1350
= 1 /5
Hence, Pyramid B is 5 times bigthan ger pyramid A
In percent, it is the volume of Pyramid B 500% bigger than Pyramid A
