Answer:

0.21

Step-by-step explanation:

The given expression is :

0.5\times \sqrt{0.09}-2\sqrt{0.05}+\sqrt \frac{1}{4}

We need to solve it.

We know that,

\sqrt{0.09}=0.3\ and\ \sqrt{0.05}=0.223

So,

0.5\times \sqrt{0.09}-2\sqrt{0.05}+\sqrt \frac{1}{4}=0.5\times 0.3-2\times 0.22+0.5\\\\=0.21

or

=\dfrac{21}{100}

So, the value of the given expression is equal to 0.21.

<span>Work:
</span>
1 gallon of water requires 3/4 teaspoon of plant food, so multiply 3/4 by 5

3/4  ×  5

Make 5 into a fraction

3/4  ×  5/1

Multiply the denominator by the denominator and the numerator by the numerator

 3   ×   5            15
----     ----    =   ------
 4   ×   1<span>             4

15/4  is an improper fraction, so make it a mixed fraction

15/4  =  3 and 3/4

Answer:

Pedro should mix 15/4  teaspoons or 3 and 3/4  teaspoons  of plant food into 5 gallons of water.</span>
