Arectangle with a height of 2 cm and length of 9 cm on her computer. the length of the new rectangle is 13.5 cm. find the height of the new rectangle.

6.5cm

Step-by-step explanation:

Because the equation for a rectangle is:

Length * Width = Area

We can find out the height of the new rectangle by finding the difference between the heigh and length of the first computer:

9 - 2 = 7

So 13.5 - 7 = 6.5

So the height of the new rectangle is 6.5cm

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1

step-by-step explanation:

at each of the parallel lines adjacent angles are supplementary. the angles have special names identifying their positions with respect to the parallel lines and transversal. they are corresponding angles, alternate interior angles, or alternate exterior angles. an angles is congruent to its matched angle.
