The centroid C divides the length of each median PY, ZQ, and XR into the ratio of 2:1 as shown in the diagram below
a) CY = 10
PC = 2×10 = 20
PY = 20+10 = 30
b) QC =10
ZC = 10÷2 = 5
ZQ = 10+5 = 15
c) PX = 20
PQ = 2×20 = 40

The number (in scientific notation) is:
The power of "-4" tells us to move the decimal point 4 places to the left.
So, moving it, the number becomes:
