Answer:

1.6 hours

Step-by-step explanation:

Leah practices dance for 2 hours each week.

Her younger sister Sonia practices dance for 0.8 the amount of time Leah practices.

The time of practice by Sonia = 0.8 of 2 hours

= 0.8 × 2

= 1.6 hours

Converting 1.6 hours to hours and minute.

1 hour (0.6 × 60) 36 minutes

Sonia practices dance for 1 hour 36 minutes each week.

Which of the following is equivalent to

enot [183]

Answer:

Option (2) is correct.

$18-\sqrt{-25}=18-5i$

Step-by-step explanation:

Given expression $18-\sqrt{-25}$

We have to find an equivalence value to the expression.

<u> Radical rule</u>,

$\sqrt{-a}=\sqrt{-1} \sqrt{a}$

Also, $i=\sqrt{-1}$

Consider the given expression,

$18-\sqrt{-25}$

Applying radical rule to $\sqrt{-25}$

$\sqrt{-25}=\sqrt{-1}\sqrt{25}=5i$

Thus, the expression becomes,

$18-\sqrt{-25}=18-5i$

Thus, option (2) is correct.
