The ratio of the bake time for a pepperoni pizza (P) and a cheese pizza (C) is modeled by the equation: P = 3C - 2. A.) If a small cheese pizza should bake for 12 minutes, how long should you bake a small pepperoni pizza? B.)If a small cheese pizza should bake for 12 minutes, how long should you bake a small pepperoni pizza?

34 minutes

Step-by-step explanation:

Given:

Ratio of time for which Pepperoni pizza and cheese pizza should be baked is given as:

Where is the time for which pepperoni pizza should be baked and

is the time for which Cheese pizza should be baked.

Also, it is given that a small Cheese pizza should be baked for 12 minutes.

In other words, we are given that:

To find:

For how long small pepperoni pizza should be baked ?

In other words,

Solution:

Let us put the value of in the equation of the model.

Therefore, a small pepperoni pizza should be baked for 34 minutes.

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.
