There 2 ways to solve this
1- Directly :
80% of water in the fresh berries è 20% of water in the dried berries
36 Ibs of the fresh berries è X Ibs of the dried berries
X =
<span> = 9 Ibs</span>
<span>2- </span>If you do not understand the first method, the second one is more explicit:
First, we gonna calculate the weight of the berries without water (dehydrated):
<span>36 * 80% = 28.8 Ibs (of water in the berries)</span>
Then:
<span>36 – 28.8 = 7.2 Ibs (of completely dehydrated berries)</span>
Next, we gonna add 20% of water in the dehydrated berries:
X (total weight of dried berries) è 100%
7.2 Ibs of dehydrated berries è 80%
X = <span> </span>
= 9 Ibs
Answer:
Allowing the birds to avoid many types of predators.
The process that happens in the given statement above is the chemical evolution. The chemical evolution allows cells to generate where as when time prolongs or goes on, complex molecules are being created in which they came from simple molecules. They are being created because of the reactions that occur chemically, generating or evolving them as time goes by.
Hello.
The answer is: A. the buoyancy of water
hydrometer is an instrument used to measure the specific gravity of liquids; that is, the ratio of the density of the liquid to the density of water, Used for measuring the relative density of liquids based on the concept of buoyancy.
