Front

What is scientific notation?

Back

A way of expressing numbers that are too large or too small to be conveniently written in decimal form, using powers of ten.

Front

Convert 6.52 x 10^{10} to standard notation.

Back

65,200,000,000

Front

How do you calculate distance traveled based on gas cost and mileage?

Back

Distance = (Amount of money / Cost per gallon) x Miles per gallon.

Front

If gas costs $3.05 per gallon and the car travels 27 miles per gallon, how far can you travel with $95?

Back

840 miles.

Front

What is the formula for calculating population growth rate?

Back

Growth Rate = (CBR - CDR + Immigration - Emigration) / 1000.

Front

Calculate the growth rate with CBR = 10, CDR = 2, Immigration = 5, Emigration = 7.

Back

0.6%.

Front

What is Net Primary Productivity (NPP)?

Back

The rate at which plants in an ecosystem produce net useful chemical energy; NPP = GPP - Respiration.

Front

If NPP is 2.3 kgC/m2/year and respiration is 1.8 kgC/m2/year, what is GPP?

Back

GPP = 4.1 kgC/m2/year.

Front

What is Gross Primary Productivity (GPP)?

Back

The total amount of carbon fixed by photosynthesis in a given area and time.

Front

If GPP is 5.8 kgC/m2/year and respiration is 2.5 kgC/m2/year, what is NPP?

Back

NPP = 3.3 kgC/m2/year.
