-- I hope you stay safe and extra healthy. Don't let those annoying hands of yours touch your germ-free face! Make sure to wash your hands extra this time and use a lot of PURELL, just, don't dry your hands out, so, make sure you have enough hand lotion. Hope this helped! (Also, masks are great! Don't use gloves because you put germs on the gloves, then, when you take them off, you touch the germs that were on your gloves.)

Rectangle ABCD is graphed in the coordinate plane. The following are the vertices of the rectangle: A(-4, -2), B(-2, -2), C(-2,

vladimir2022 [97]

Answer:

The area of rectangle ABCD is $18\ units^2$

Step-by-step explanation:

Plot the figure to better understand the problem

we have the vertices

A(-4, -2), B(-2, -2), C(-2, 7), D(-4, 7)

see the attached figure

The area of the rectangle is equal to

$A=LW$

where

L is the length

W is the width

In this problem we have

$L=BC=7-(-2)=9\ units$ ---> difference of the y-coordinates

$W=AB=-2-(-4)=2\ units$ ---> difference of the x-coordinates

substitute

$A=(9)(2)=18\ units^2$

Sara and Jenny can both do flips in the air. The ratio of the number of flips Sara can do to the number of flips Jenny can do is

Snowcat [4.5K]

Wow! I never had problems this hard in middle school!

But you can do it!

First, we need to figure the number of flips Sara can do based on Jenny's.

Jenny = 120 and Sara - 120 x 3/8 (because she is only 3/8 of Sara's)

Calculate 120 x 3/8 = 45 flips

Now we know that Sara increased her amount of flips by 3 (45 +3 = 48)

And we know that Jenny decreased hers by 12 (120 - 12 = 108)

So now we have a ratio of 48:108, but we need to simplify that with factoring.

I am going to divide first by 2.

24:54

Then 2 again...

12:27

How about 3?

4:9

I think that is as far as we can go.

Sara is now doing 4 out of every 9 that Jenny does.

Check it!

108 (Jenny) x 4/9 = 48 (Sara) Yes! It checks.
