Identify two additional values for x and y in a direct variation relationship where y =11 when x=18
Ann [662]
In a direct variation relationship the values must satisfy that y = kx. This si y is always a constant value (k) times x.

So, you can find multiple values that meet this:

y = kx => k = y / x = 11 / 18

=> y = (11/18)x

Now you can give any value to x and fint the value of x that satisfy the relationship:

x           y = (11/18)x

1           11/18

2           11/18 * 2 = 11/9

18          11/18 * 18 = 11

36           11/18 * 36 = 22

So, there you have several additional values for x and y in the same relationship that y = 11 and x = 18, and you can find many more using the same rule: y = (11/18)*x

Raja is making small, cone-shaped horns out of clay for an art project. Each horn is 16 centimeters tall with a base diameter of
kotykmax [81]

Answer: Raja needs 150.72 cubic centimeters for each horn.

Step-by-step explanation:

Since the horns that Raja is making are cone shaped, then we would determine the amount of clay she needs by applying the formula for

determining the volume of a cone is expressed as

Volume = 1/3πr²h

Where

h represents the height of the cone.

r represents the radius of the cone

π is a constant whose value is 3.14

From the information given,

Height = 16 centimeters

Diameter = 6 centimeters

Radius = diameter/2 = 6/2 = 3 centimeters

Therefore,

Volume = 1/3 × 3.14 × 3² × 16 = 150.72 cubic centimeters
