Answer:
Apple juice there are 95.9 mg
Orange juice there are 87.1 mg
Step-by-step explanation:
We can get a system of equations from the statement.
Let x be the amount of vitamin C in apple juice
Let y be the amount of vitamin C in orange juice
Now, with the statement we have to:
x + y = 183 (1)
2 * x + 3 * y = 453.1 (2)
We have an equation system, of 2 equations with 2 unknowns, that is, it has a solution.
If we multiply the first equation by 2 and subtract the second equation, we are left with:
2 * x + 3 * y - 2 * x - 2 * y = 453.1 - 2 * 183
Solving
y = 453.1 - 366
y = 87.1
Now to calculate x:
x + y = 183
x + 87.1 = 183
x = 183 - 87.1
x = 95.9
To check:
https://es.symbolab.com/solver/step-by-step/x%20%2B%20y%20%3D%20183%3B%202%5Ccdot%20x%20%2B%203%5Ccdot%20y%20%3D%20453.1
Therefore in apple juice there are 95.9 milligrams of vitamin C and in orange juice there are 87.1 milligrams.
there are 60 seconds in 1 minute.
there are 60 minutes in 1 hour.
so in 1 hr there are 60 * 60 seconds, 60 minutes 60 times :).
so 1 hr has 3600 seconds then.
how many seconds in 17 hours? well just 17 * 3600, their product.
we know the photon can do 3x10⁸ meters in one second, namely 300000000 m/s.
so, how many meters did it travel in 17 hours?
well, we know 17 hours is (17*3600) seconds
so, we can say, how many seconds did the photon travel in (17*3600) seconds? we know it can do 3x10⁸ in 1 second alone.
so the distance travelled is just their product, (17*3600) * 300000000.
so is really just 18360000000000 meters, or in scientific notation, there are 10 zeros and then we move the dot over 3 more slots in front of the "1", 1.836 x 10¹³.
