Helena creates two similar rectangles using exactly 100 cm of string. The smaller rectangles width and length are 4 cm by 6 cm r

Misha Larkins [42]

Answer:

The dimensions of the larger rectangle are $24\ cm$ of length by $16\ cm$ of width

Step-by-step explanation:

Let

x-----> the length of the larger rectangle

y-----> the width of the larger rectangle

we know that

$\frac{x}{y}=\frac{6}{4}$ ------> by similar rectangles

$x=1.5y$ -----> equation A

<u>Find the perimeter of the smaller rectangle</u>

$P=2(6+4)=20\ cm$

<u>Find the perimeter of the larger rectangle</u>

Subtract the perimeter of the smaller rectangle from 100 cm of string

$P=100-20=80\ cm$

Remember that

$80=2x+2y$ ------> $40=x+y$ ------> equation B

substitute equation A in equation B

$40=1.5y+y$

$2.5y=40$

$y=16\ cm$

Find the value of x

$x=1.5(16)=24\ cm$

The dimensions of the larger rectangle are $24\ cm$ of length by $16\ cm$ of width

Which of the following equations represents the graph shown?

melomori [17]

Answer: Last option.

Step-by-step explanation:

The equation of the line in slope-intercept form is:

$y=mx+b$

Where m is the slope and b the intersection with the y-axis.

You can observe in the graph that the line passes through the origin, then:

$b=0$

Choose two points of the line and calculate the slope with:

$m=\frac{y_2-y_1}{x_2-x_1}$

Points: (2,3) and (-2,-3)

Substitute values, then the slope is:

$m=\frac{-3-3}{-2-2}=\frac{-6}{-4}=\frac{3}{2}$

Substituting "m" and "b" into $y=mx+b$ , you get that the equation is:

$y=\frac{3}{2}x$

This can be written as:

$f(x)=\frac{3}{2}x$
