Answer:
Because the dried fruit contains less water
Step-by-step explanation:
Drying is a phenomenon whereby heat is used to remove moisture from a material.
Fruit juice contains about 85% water, that means the remaining fruit content is 25%
The average water content of fruits is about 89%, this means that the remaining fruit content is 11%.
Dried fruit contains about 20% water which means that the remaining fruit content is 80%.
If we assume that each cup serving weighs 1kg this implies that;
The real fruit content (vitamins, minerals etc) masses are;
Fruit juice = 0.25kg
Fruit = 0.11kg
Dried fruit = 0.8kg
We can see that the mass of the fruit content in the dried fruit is twice more than than of the fruit and fruit juice individually. This is why half cup of dry fruit is equated to one cup of the other two.
Answer: square root 50 that does not belong
Step-by-step explanation:
The total revenue that is gained from the sales of the cakes is determined by multiplying the number of cakes by the price. If we let x be the number of $1 that should be deducted from the price and y be the total revenue,
y = (25 - x)(100 + 5x)
Simplifying,
y = 2500 + 25x - 5x²
We get the value of x that will give us the maximum revenue by differentiating the equation and equating the differential to zero.
dy/dx = 0 = 25 - 10x
The value of x is 2.5.
The price of the cake should be 25 - 2.5 = 22.5.
Thus, the price of the cake that will give the maximum potential revenue is $22.5.
