I don’t think you pick an answer you just put all of those formulas and solutions into your calculator and that will give you what you need to move onto the next question/ step
Answer:
611 square miles
Step-by-step explanation:
Area of triangle = (1/2)*a*b*sinC (formula when u are not given the height of the triangle, but u are given with the angle.)
= (1/2)*30*47*sin(60°)
= 610.54 square miles (2 d.p)
≈611 square miles (rounded to nearest mile)
:)
we are given
there are in 0.073 gallons
we can see that there are two non-zero places after decimals
so, there are two siginificant figures
step-1: Change gallons to quarts
we know that
1 gallon = 4 quarts
so, we can write as



step-2: Change into liter

we know that
1 liter = 1.057 quarts
or




step-3: Change into millilitre
we know that



Since, it is asking for only two significant figures
so, we can also write as
