Flura [38]

Answer: 20 minutes

Step-by-step explanation:

She has 45 mins to complete her writing paper.

She spends: $10\frac{1}{8}$ minutes to plan her paper.

She spends: $15\frac{1}{2}$ minutes writing rough drafts.

How much time left does she have?

$45-(10\frac{1}{8} +15\frac{1}{2})$

$45-(10+15(\frac{1}{8}+\frac{1}{2}))$

$45-(25\frac{(1)(2)+(8)(1)}{(8)(2)})$

$45-(25\frac{2+8}{16} )$

$45-(25\frac{10}{16})$ Simplify the fraction.

$45-(25\frac{5}{8})$

$45-25(\frac{5}{8})$

So she has approximately,

$20\frac{5}{8} =\frac{165}{8}= 20$ minutes.

Answer:

Step-by-step explanation:

Using the rule of radicals

$\sqrt{a}$ = $a^{\frac{1}{2} }$

Thus

( $\sqrt{a}$ )² = $a^{\frac{1}{2} }$ × $a^{\frac{1}{2} }$ = $a^{(\frac{1}{2}+\frac{1}{2}) }$ = $a^{1}$ = a → B
