Answer:
B. 140 in^2
Step-by-step explanation:
A = 1/2(b1 +b2)(h)
=1/2(15 + 4 + 15 + 6)(7)
=1/2(40)(7)
= 140 in^2
15x-10=10 6+2X is what I got from what u typed
For getting to the answer of this question, one has to know the conversion between kilometer and miles as well as the conversion between gallons and liter.
1 mile = 1.609 km
Then
16 km = 16/1.609 miles
= 9.94 miles
Again
3.785 liter = 1 gallon
then
1 liter = 1/3.784 gallons
= 0.26 liter
So
16 km/L = (9.94/0.26) miles per gallon
= 38.23 miles per gallon.
= 38 gallons
