Kilo is the unit prefix for multiplication by one thousand. Therefore, a kilogram, or kg, is equal to one thousand grams. To convert grams to kilograms, you simply have to multiply the number of kilograms to grams.
So, for example, if you had 16.24kg of a compound, it would equal:
Answer:
B=16 ounces
C=24 ounces
B=1/0.75=133%
Step-by-step explanation:
we have that
A≡0.25B (25%), if A=4 ounces then B=4/0.25 = 16 ounces
C=1.5B (150%), if B=16 ounces then C=1.5*(16 ounces) = 24 ounces
D≡xB (?%), if D=12 ounces then x=12/16 = 0.75 ≡ 75%, but xB≡D ⇒ B≡D/x →
B≡12(1/0.75)= B=12*(1.333)→ B≅133%D
The answer is area= 113.05 Circumference= 37.68
Answer:
P is exactly 3km east from the oil refinery.
Step-by-step explanation:
Let's d be the distance in km from the oil refinery to point P. So the horizontal distance from P to the storage is 3 - d and the vertical distance is 2. Hence the diagonal distance is:

So the cost of laying pipe under water with this distance is

And the cost of laying pipe over land from the refinery to point P is 400000d. Hence the total cost:

We can find the minimum value of this by taking the 1st derivative and set it to 0

We can move the first term over to the right hand side and divide both sides by 400000


From here we can square up both sides






d = 3
So the cost of pipeline is minimum when P is exactly 3km east from the oil refinery.
