Which expression represents rational numbers? Select all that apply

Masja [62]

Answer:

A, B, C and F

Step-by-step explanation:

We have according to the options:

A. $\sqrt{100} \times \sqrt{100}=10\times 10=20$

B. $13.5+\sqrt{81} =13.5+9=22.5$

C. $\sqrt{9}+\sqrt{729}=3+27=30$

D. $\sqrt{64}+\sqrt{353}=8+\sqrt{353}$ , which is not rational.

E. $\frac{1}{3}+\sqrt{216}=0.3+6\sqrt{6}$ , which is not rational.

F. $\frac{3}{5}+2.5=0.6+2.5=3.1$

Hence, the expressions representing rational numbers are A, B, C and F.

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.
