Sum means add
the number is x
13 divided by a number is 13/x
the number divided by the number is x/13
so

also can be simplified to

or

translated it is

where x is the number
The sum of the percentages of milk and dark chocolate needs to equal 100%.
Since dark chocolate is 25%, then milk chocolate must be 75%
Now we can set up a proportion:
75% = 3 lbs
25% = X lbs
Dark chocolate = (3 x 25%) / (75% x X) = 1 lb
Answer:
Osa
Step-by-step explanation:
<u>Relative distances</u>
Osa is in a submarine 200 feet under sea level. We can say its distance to sea level is 200 feet
Jill is 311 feet above sea level, her distance to sea level is 311 feet
We can say Osa is closest to sea level
If we consider ground level to the reference where distances are measured from above, then we must say Osa is closest to it because she is below sea level and naturally, closer to the ground below it
The answer is 840 cm just do length times width times height
