Answer:

19.65

Step-by-step explanation:

you line 28.9 with 9.25 below it and then you subtract it. take it one column at a time.

28.9

- 9.25

the imaginative zero becomes 10 and then the 9 becomes an 8 so 10-5=5 and 8-2=6

then you subtract 9 from 28 and get 19

The equation 3y=5x represents a proportional relationship. what is the constant of proportionality for this relationship

Citrus2011 [14]

The constant of proportionality for this relationship is $\frac{5}{3}$

Step-by-step explanation:

Proportional relationship is the relation between two variables that vary directly with each other

If x and y are proportion, then y = k x, where k is the constant of proportionality
If x and y are proportion, then $\frac{y}{x}=k$ , where k is the constant of proportionality

∵ The equation is 3 y = 5 x

∵ x and y are proportional

- That means y = k x, where k is the constant of proportionality

∴ Put the equation in the form y = k x

- Divide both side by the coefficient of y

∵ The coefficient of y is 3

∴ Divide both sides of the equation by 3

∴ y = $\frac{5}{3}$ x

- The value $\frac{5}{3}$ is constant

∴ k = $\frac{5}{3}$

∵ k represents the constant of proportionality

∴ The constant of proportionality = $\frac{5}{3}$

The constant of proportionality for this relationship is $\frac{5}{3}$

Hey does anyone know this

Readme [11.4K]

- Use the formula V = π <span>∙ r2 ∙ h.
- Plug into the equation. 27</span>π(cubed)=π∙3(2)∙h
-Solve. 27π(3)=9π∙h
27π/9π=3π
I believe the height is 3π.
