A parallelogram which has a line of symmetry is a rectangle<br>true or false​
ch4aika [34]
<h3>Answer: False</h3>

Explanation:

If a parallelogram has a line of symmetry through each pair of opposite sides, then we have a rectangle.

But if a parallelogram has a line of symmetry through each pair of opposite vertices, then we have a rhombus.

A square is a combination of both cases above.

The statement "A parallelogram which has a line of symmetry is a rectangle" is sometimes true. Overall its false because it implies that all parallelograms with this property are automatically a rectangle.

A hotel must increase its price by 5% per night, if the new price is $168 per night. What was the original cost?
ValentinkaMS [17]

Hey there! I'm happy to help!

We see that if you add 5% to the original cost, we have $168 as our cost. This means that 105% of the original cost is 168. Let's set up an equation to find the original cost. Let's call our original cost c.

To turn a percent into a decimal, you divide by 100.

1.05c=168

We divide both sides by 1.05.

c=160

Therefore, the original cost was $160.

Have a wonderful day! :D
