The standard form of an imaginary number is <span>a ± bi where a is the real number and b is the imaginary number. The answer hence is false. i related to an imaginary number is equal to square root of -1. Hence when i is squared, the answer should be -1. Answer is false. Complex numbers can be graphed only in an plane with an imaginary axis and a real axis/ Answer in 3 is false</span>

Mon wants to make 5 lbs of the sugar syrup. How much water and how much sugar does he need to make 5% syrup?
ICE Princess25 [194]

4.75 lbs of water and 0.25 lbs of sugar is needed to make 5% of syrup.

<u>Solution:</u>

Let us assume that x is the required pounds sugar to make 5% syrup

\Rightarrow\frac{x}{\text{total quantity}}=5\%

which is \frac{x}{5}=5\%

On solving we get,

\Rightarrow\frac{x}{5} =0.05 [5\%=\frac{5}{100}]

\Rightarrow x = 5\times0.05\rightarrow x=0.25

If the required sugar to make 5% syrup is 0.25 lbs then the remaining quantity in the total sugar syrup would be water. That is,

5 \text{ lbs }-0.25 \text{ lbs }=4.75 \text{ lbs }

So, the required amount is 0.25 lbs of sugar and 4.75 lbs of water.
