The length of a rectangle is 4 meters less than three times its width. Its area is 615 square meters. What are the dimensions of

Anarel [89]

Area= length*width

width=W

W*(3W-4)=615
3W^2-4W=615
3W^2-4W-615=0
W=41
W=-45
But W cant be a negative number so it is 41m (width)
The length is (41*3)-4=119m (length)

Data set A have a median of 2, mean of 3.4, min of 1 and max of 9. range of 8
Data set B have a median of 7, mean of 6, min of 1 and max of 12, range of 11
so Data set B is much bigger than data set A

What is the slope of a line that is perpendicular to the line whose equation is 2y = 3x - 1?

alexandr1967 [171]

Answer:

The slope of the line is $-\frac{2}{3}$

Step-by-step explanation:

For any line $y=mx+b$ , a line that is perpendicular to it is $y_\perp =-\frac{1}{m} x+b$ .

Therefore the slope of the perpendicular line is $-\frac{1}{m}$ .

For our case $y=\frac{3}{2}x-\frac{1}{2}$ therefore the slope of the prependicular is the reciprocal of $\frac{3}{2}$ multiplied by $-1.$

$\therefore\:slope=-\frac{2}{3}.$

What is product of x/3 and 6/x when x=0 ? <br>A.2 <br>B.18 <br>C.2/x^2<br> D.18/x^2

Ahat [919]

Answer:

A) But if anyone thinks this they should go back to preschool

Step-by-step explanation:

On any other value of x you would take the numerators and denominators and multiply them across:

$\frac{x}{3}*\frac{6}{x}=\frac{x*6}{x*3}=\frac{6}{3} =2$

But, this literally does not make since considering the fact that you cannot divide any value by zero. Try it, it won't work. If we plug these into a trusty dusty calculator, we get this:

$\frac{0}{3}=0\\\\\frac{6}{0}=DOMAINERROR$

0*DOMAINERROR= You can't do it.

There are other reasons why you can't divide by zero, I would suggest looking them up on YT and learning about them.

I would answer A, but the person who wrote this question just wasn't focusing when they wrote the question.
