What is the constant of proportionality in the equation?
IrinaVladis [17]

Answer:

The constant of proportionality is option D i.e 5.

Step-by-step explanation:

Variation:

Variation problems involve fairly simple relationships or formulas, involving one variable being equal to one term. There are two types of variation i.e.

  1. Direct variation
  2. Inverse variation

Direct Variation:

Mathematical relationship between two variables that can be expressed by an equation in which one variable is equal to a constant times the other.

Example y=kx

where, k  is constant of proportionality.

The above given example is of Direct Variation

∴ y = 5 x

∴ k = 5 = constant of proportionality.

Inverse Variation:

Mathematical relationship between two variables which can be expressed by an equation in which the product of two variables is equal to a constant.

Example yx=k

where, k  is constant of proportionality.

A can of tuna fish is a cylinder with a height of 1.75 inches and a diameter of 3 inches. If the can is half full, how many cubi
zlopas [31]

Answer: 6.185in^3

Step-by-step explanation:

The formula for calculate the volume of a cylinder is:

V_{cylinder}=\pi r^2h

r is the radius of the cylinder and h is the height of the cylinder.

Given the diameter of 3 inches, calculate the radius of the cylinder with:

r=\frac{d}{2} (Where d is the diameter)

 r=\frac{3in}{2}=1.5in

Knowing the height and the radius, you can calculate the volume of the entire can of tuna:

V_{can}=\pi (1.5)^2(1.75in)=12.37in^3

As you want to know the cubic inches of tuna that are in the can (volume of tuna), and you know that the can is half full, then:

V_{tuna}=\frac{V_{can}}{2}\\\\V_{tuna}=\frac{12.37in^3}{2}\\\\V_{tuna}=6.185in^3
