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)

Answer:
3/8 = 9/24
Step-by-step explanation:
So here we have a basic multiplication problem and finding the LCM of 8 and 3. The first step in this problem is finding the LCM of 3/8. The LCM of 3 and 8 is 24. So yay! we have the bottom half of our answer!
Ex.-
The LCM of 8 and 3 is 24.
So now we have to find an equivalent fraction. Since we already know that 8 (the denominator in the original equation) can be multiplied by 3 to equal 24, we use 3 (the numerator in the original equation) and multiply it by itself to get an equivalent fraction.
Ex.-
8 x 3 = 24
3 x 3 = 9
Now that we have our numerator and denominator, all we have to do now is put them together to get our answer.
Ex.-
9/24 (answer) = 3/8 (original equation)
Hopefully I could help! :)
I agree with your answer "supplementary". The two angles combine to form 180 degrees, aka a straight angle
