Answer:
(1.989×10^27 kg) × (10^6 mg/kg) = 1.989×10^33 mg
(1.989×10^33 mg) × (10^-6 kg/mg) = 1.989×10^27 kg
Step-by-step explanation:
"kilo-" and "milli-" are SI prefixes for the mass unit "gram". Respectively, they mean 10^3 and 10^-3 of the unit whose name they're attached to.
So, 1 kg = 1000 g, and 1 mg = 0.001 g. Hence 1 kg = 10^6 mg.
__
Using this fact, we can express the mass of Jupiter as ...
1.989×10^27 kg = (1.989×10^27)(10^6 mg) = 1.989×10^33 mg
__
We can multiply the above kg/mg relation by 10^-6 and get ...
10^-6 kg = 1 mg
Then we can express the mass of Jupiter as ...
1.989×10^33 mg = (1.989×10^33)(10^-6 kg) = 1.989×10^27 kg
One solution let's find that
2/4 divided by 5/4=
.4 or 2/5 (both are same, once is decimalic form and one is fraction form)
Answer:
B
Step-by-step explanation:
-3/4y - 1/5y = 380 can be simplified to -19/20y = 380.
In order for the student to incorrectly get 361, they likely just multiplied the 380 by 19/20 rather than multiplying by the reciprocal (which would be -20/19).
This means the best answer should be B.
International Monetary Fund (IMF)so hes right!
