A parallelogram which has a line of symmetry is a rectangletrue or false​

Mathematics

<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.

Jessica is shopping for a new car. She found a blue car that has a 12-gallon gas tank and can go 384 miles on one tank. She foun
adelina 88 [10]

Answer:

Silver car

Step-by-step explanation:

It seems pretty hard but it's actually REALLY easy. gas mileage means the number of miles you can go on a particular amount of gallons. But the gallons have to be the same for both cars so that it's fair.

so let's go with 10 gallons. pretty broad number right?

so to get 12 gallons(the gallons for the blue car) to 10, We divide it by 12 then multiply it by 10. Try it yourself, (12/12)*10=???

then we do that to 384 (the miles for the blue car)

(384/12)*10=320

so 320 is the mileage for the first car. Repeat the steps for the silver car!

(14/14)*10=10

so then: (504/14)*10= 360.

So which is bigger, 320 or 360?

360 is bigger, meaning it has better gas mileage.
