Which pairs of variables have a linear relationship? Select

Mathematics
2 answers:
Neko [114]3 years ago

Answer:

Side length and perimeter of 1 face

Area of 1 face and surface area

Step-by-step explanation:

Suppose you are given cube with side length of x units.

Then

Side length = x units

Perimeter = 4x units

Area of 1 face =x^2 square units

Surface area =6x^2 square units

Volume =x^3 cubic units

A linear relationship is any equation that, when graphed, gives you a straight line.

Consider all options:

A. Side length and perimeter of 1 face is a linear relationship, because the graph of the function y=kx is a straight line.

B. Perimeter of 1 face and area of 1 face is not a linear relationship, because the graph of this relationship is a quadratic parabola with equation y=kx^2.

C. Surface area and volume is not a linear relationship, because the graph of this relationship is a curve with equation y=kx^{\frac{3}{2}}.

D. Area of 1 face and surface area is a linear relationship, because the graph of the function y=kx is a straight line.

E. Side length and volume is not a linear relationship, because the graph of this relationship is a cubic parabola with equation y=kx^3.

The side lengths of a triangle are 6, 8, and 12. Is this a right triangle?
gizmo_the_mogwai [7]
<h2><u>D.</u></h2><h3>It's incorrect, because 6 squared = 36, 8 squared = 64, add them together and you get 100. 12 squared does NOT equal 100, it equals 144.</h3>

<em>(To find the hypotenuse {longest side of the triangle}, you square the two short sides, add them together, and finally, divide it by the provided number, and see if the number matches the provided number's square.)</em>

<h3>Brainly if correct and Thanks!</h3>

Carrie is driving to a friend’s house for the weekend. The friend lives in a town 160 mi. away. So far, Carrie has driven 64 mi.
ankoles [38]

Divide the amount she drove by the total amount she needs to drive, them multiply that answer by 100 to make it a percent. This will give you the percentage she drove. To find the percentage she has left,, subtract from 100%.


64 / 160 = 0.4

0.4 * 100 = 40%  (  percent she has already driven)


100% - 40% = 60% left.

Which of these true conditional statements has a false converse?
DENIUS [597]

Not sure if I'm right but i think the answer is C.

If a figure has four sides, its not always a square. It could be a trapezoid, or another four sided shape. The other converses for A and B are true.
