So, 420 miles=12 gallons
That means that for 1 gallon you would be able to go 35 miles.
Just multiply that by 8. 35*8=280
Answer:
70
Step-by-step explanation:
Apparently, you want the ratio of the weights:
(dino weight)/(car weight) = (2.8×10^5)/(4×10^3)
= (2.8/4)×10^(5-3) = 0.7×10^2 = 0.7×100
= 70
The heaviest dinosaur weighed about 70 times the weight of an average car.

Your calculator can do arithmetic in scientific notation. So can any spreadsheet.
The applicable rule of exponents is ...
(10^a)/(10^b) = 10^(a-b)
the answer is 2c you - the five with four then you gaana have 1c +1c equal 2c.
Answer:
2 miles
Step-by-step explanation:
distance=rate*time
d=rt
1/6=r*(1/12)
multiply both sides by 12
12(1/6)=r*(1/12)12
2=r*1
2=r
rate=2 miles per hour
