Answer:

The initial amount, 1.3 million = 1,300,000 is the 100%.

now, 640,000 is a given percentage (lower than 100%) of that.

How we can find it?

suppose that 640,000 represents an x%.

Then we have that the quotient between the actual quantities and the percentages must be the same

(640,000/1,300,000) = x%/100%

x% = (640,000/1,300,000)*100% = 49.23%

Then the percentage declined is:

100% - 49.23% = 50.77%

The other question can not be answered with the given information.

emmasim [6.3K]

Answer:

White

Some times when we look at some objects they appear to be different in color to us than their actual color. It may be due to several wavelength of  light with different intensities is striking on our eye.

Remember, white is not a color it is just produced in response to combination of 3 or more than three colors like light.

The three colors that can be combined at full intensity to form a white color are called as primary colors. The most common set is

               Red+Green+Blue= white

Zero intensity of each component gives darkest color and full intensity of any component give a white color.

Secondary colors can be produced by the addition of two colors such as;

                Red+Green=Yellow

                Red+Blue=Magneta

                Green+Blue=Cyan

alukav5142 [94]

The following statements apply:

1. Salt is not chemically bonded to water.

2. The ratio of salt to water may vary.

3. Salt and water retain their own chemical properties.

The solution formed by dissolving salt in water is an example of a mixture, it is a physical change and no new substance is formed. The salt and the water are not chemically bonded and salt can easily be recovered from the water by mean of evaporation. Any amount of salt can be dissolved in the water and each of the component, that is, salt and water still retain their individual chemical properties.
