Answer:

r = 7

Step-by-step explanation:

To solve this, we can plug in a pair of x and y values and solve for r.

y = rx | Plug in a pair

42 = r*6 | Now divide both sides by 6

7 = r.

We can test this by plugging in r with a pair.

y = (7)x

77 = 7*11, 77 = 77, This equation is correct.

<h2>Answer:</h2>

The constant of proportionality r in the equation is:

                       r = 7

<h2>Step-by-step explanation:</h2>

We know that for the equation of the type:

                y=rx

The constant of proportionality is given by the equation:

 r=\dfrac{y}{x}

i.e. it is the ratio of the output to the input values.

Here we have a table of values as follows:

      x        y

      2       14

      6       42

      11      77

Hence, with the help of any one set of value we will get the value of r.

We take the set (2,14)

i.e.

r=\dfrac{14}{2}\\\\r=7

The area of a rectangular field is 6052 m².
Aleonysh [2.5K]

Answer:

<h2>length = 89 m</h2>

Step-by-step explanation:

Area of a rectangle = l × w

where

l is the length

w is the width

From the question

Area = 6052 m²

width = 68 m

To find the length substitute the values into the above formula

6052 = 68l

Divide both sides by 68

We have the final answer as

<h3>length = 89 m</h3>

Hope this helps you

A glass containing water is in the shape of a right circular cylinder with a radius of 3
Lubov Fominskaja [6]

Answer:

Step-by-step explanation:

The equation for a cylinder is the radius of the circle times pi squared, multiplied by the height. 3 squared is 9, times pi is 9(pi). If we multiply this by the height, the answer is 90(pi) centimeters in volume.
