PLEASE HELP!!!<br> Which expressions simplify to a rational answer? Select each correct answer.

Bond [772]

ANSWER

The first three expressions will simplify to a rational answer.

EXPLANATION

Let us simplify the expressions then we can see which of them are rational.

$7\sqrt{3} \times \sqrt{3}$

We multiply out the roots to get

$7\sqrt{3} \times \sqrt{3}=7 \times (\sqrt{3})^2$

This simplifies to

$7\sqrt{3} \times \sqrt{3}=7 \times 3$

$7\sqrt{3} \times \sqrt{3}=21$

This is a rational number hence the answer is rational.

$\sqrt{5} \times \sqrt{5}=(\sqrt{5})^2$

$\sqrt{5} \times \sqrt{5}=5$

This is also a rational solution.

$2\sqrt{9} \times \sqrt{4}=2\times3\times2$

$2\sqrt{9} \times \sqrt{4}=12$

This one too is a rational solution.

$\sqrt{3} \times \sqrt{16}=\sqrt{3}\times4$

$\sqrt{3} \times \sqrt{16}=4\sqrt{3}$

This is an irrational answer because √3 is an irrational number and multiplying a rational number, 4 by an irrational number results in an irrational number.

A salesperson has to drive 500 miles. For the first three hours she drove at 65 mi/h. For the next two hours she drove at 55 mil

yarga [219]

Answer: she has 195 miles more to cover

Step-by-step explanation:

A salesperson has to drive 500 miles.

For the first three hours she drove at 65 miles/hour.

Distance = speed × time.

This means that distance covered in the first 3 hours is

65 ×3 = 195 miles

For the next two hours she drove at 55 miles per hour.

This means that distance covered in the next two hours is

55 × 2 = 110 miles

The total distance that the salesperson has to cover is 500 miles

Distance already covered is

195 + 110 = 305 miles

Distance remaining will be total distance - distance already covered. It becomes

500 - 305 = 195 miles
