It takes the friend 10 minutes to wash 1/4 of a car. Yes, I believe she is correct because.

10 minutes for 1/4
40 minutes for 1 car.
40 times 6 = 240
240 divided by 6 is 4 (hours)
Sorry not sure about the unit rate!

Answer:

-6/7

Step-by-step explanation:

The slope of the line perpendicular to DE is the negative reciprocal of the slope of DE. The slope of DE is ...

(change in y)/(change in x) = (y2 -y1)/(x2 -x1) = (-3-4)/(1-7) = -7/-6 = 7/6

The inverse of that is 6/7, and the opposite of that inverse is -6/7.

The slope of the line perpendicular to DE is -6/7.

Answer:

a> h
a<164

Step-by-step explanation:

I think your question is missed of key information, allow me to add in and hope it will fit the original one.

<em>Andre notices that he is a little taller than Lin, who described her height as h > and 150 h < 160 but andre is also shorter than their math teacher who is 164 centimeters tall. select the two inequalities that describe andress height</em>

Please have a look at the attached photo.

My answer:

Math teacher's height: 164 cm

Let Andre height is :a

We have Heather height: h

<=> h > and 150 h < 160

<=> 150 < h < 160

=> two inequalities that describe Andres height

a> h
a<164

Hope it will find you well
