Expression for area of triangle
This is calculated using

Assume that:

The equation becomes

the problem is a pattern that multiplies by two and subtracts one each time.
3x2=6 6-1=5 5x2=10 10-2=9 9x2=18 18-1=17 17x2=34 34-1=33
Answer:
D 40,000nm
Step-by-step explanation: 1nm/10^-9m * 10^-6/1um = 10^3 nm/um
Therefore in 40 microns there are:
40um * 10^3 nm/um = 40 * 10^3 nm = 40,000 nm
Answer:
The 2 in the hundreths is 10% of the 2 in the tenths
Step-by-step explanation:
We are given the number 15.2201
#The value of 2 in the tenths:

#The value of 2 in the hundredths:

The difference of the 2 in the tenths and in the hundredths is:

Hence, the difference between the 2 in the tenths minus 2 in the hundreths is 0.18, 2 in the hundreths is 10% the 2 in the tenths.
The simplified version of this equation is
