To find the average population growth per year, divide the total growth in population over 2 years by 2: 600 people / 2 years = <<600/2=300>>300 people per year.
To find the projected population growth over 5 years, multiply the average annual growth by the number of years: 300 people/year * 5 years = <<300*5=1500>>1,500 people. Answer: \boxed{1,500}.
A scientist samples a deer population and finds 200 deer in an area of 10 square miles. On average, how many deer can the scientist expect to find in an area of 300 square miles?(1 point)

320 deer
To find the average number of deer per square mile, divide the total number of deer by the area: 200 deer / 10 square miles = <<200/10=20>>20 deer per square mile.
To find the expected number of deer in a larger area, multiply the average number of deer per square mile by the area: 20 deer/square mile * 300 square miles = <<20*300=6000>>6,000 deer. Answer: \boxed{6,000}.

14 cookies
28 cookies
To find the number of cookies made per batch, divide the total number of cookies by the number of batches: 42 cookies / 3 batches = <<42/3=14>>14 cookies per batch.
To find the number of cookies made with 2 batches, multiply the number of cookies per batch by the number of batches: 14 cookies/batch * 2 batches = <<14*2=28>>28 cookies. Answer: \boxed{28}.

Start Fraction 4 over 90 End Fraction miles per gallon
20 miles per gallon
To find the vehicle's consumption rate in miles per gallon, divide the number of miles driven by the number of gallons of gasoline used: 90 miles / 4 gallons = <<90/4=22.5>>22.5 miles per gallon. Answer: \boxed{22.5}.
double check everything
Apologies for the confusion. Let's go through the calculations one more time:
To find the vehicle's consumption rate in miles per gallon, we divide the number of miles driven by the number of gallons of gasoline used: 90 miles / 4 gallons = 22.5 miles per gallon.
So, the correct answer is 22.5 miles per gallon.
