Here are two rectangles.

creativ13 [48]

Answer:

$\frac{Area \:of\: rectangle\: A}{Area \:of\: rectangle\: B} =\frac{4}{3}$

Step-by-step explanation:

Let the length of rectangle A be x units.

So, length of rectangle B

= x + 25% of x

= x + 0.25x

= 1.25x

Let the width of rectangle A be y units

So, Width of rectangle B

$= \frac{3}{5}\times x\\=0.6x$

Area of rectangle A = xy

Area of rectangle B

= 1.25x * 0.6y

= 0.75xy

$\frac{Area \:of\: rectangle\: A}{Area \:of\: rectangle\: B} =\frac{xy}{0.75xy}\\\\\frac{Area \:of\: rectangle\: A}{Area \:of\: rectangle\: B} =\frac{1}{0.75}\\\\\frac{Area \:of\: rectangle\: A}{Area \:of\: rectangle\: B} =\frac{100}{75}\\\\\red{\bold{\frac{Area \:of\: rectangle\: A}{Area \:of\: rectangle\: B} =\frac{4}{3}}} \\\\$

What is the slope of the line that

Naily [24]

Answer:

The line has a slope of zero which means the line is a horizontal line.

Step-by-step explanation:

Given that:

The two points are (-3,2) and (4,2)

Slope of a line is given by the formula,

$m = \frac{Rise}{Run} = \frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

Here,

$x_{1}=-3,\ y_{1}=2\\x_{2}=4,\ y_{2}=2$

Putting these values in formula;

$m=\frac{2-2}{4-(-3)} \\m = \frac{0}{4+3}\\m = \frac{0}{7} = 0$

Hence,

The line has a slope of zero which means the line is a horizontal line.

H+20=35-4h please help

andrew-mc [135]

H+20=35-4H
first, combine your like terms, which are the Hs
add the 4H to both sides, and you will get
5H+20=35
now subtract 20 from both sides, that will cancel out the 20 on the left and leave you with
5H=15
finally, divide both sides by 5 and you will get H=3.

PLEASE PLEASE HELP!! 30 POINTS!!

LenKa [72]

There is no rate of change.

x=8 and x=13 are horizontal lines going to infinity and negative infinity, its valid for all reals on those 2 lines.

I'm guessing you left out some information on what kind of interpretation you want of these straight lines.
