Answer:

33 minutes and 45 seconds.

Step-by-step explanation:

We can easily set up a proportion...

He can paint 8 rocks in 5 minutes. He can paint 54 rocks in x minutes.

\frac{8}{5} =\frac{54}{x}

8 * x = 54 * 5

8x = 270

4x = 135

x = 33.75

So, it will take Ronnie 33 minutes and 45 seconds to paint 54 rocks.

Hope this helps!

Call center A and B offers equal wages.

<h3>what is Equation?</h3>

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side. It demonstrates the equality of the relationship between the expressions printed on the left and right sides LHS = RHS is a common mathematical formula.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given:

The formula for wages = P/t

First, P= 15 dollars

           = 1500 cents

time= 1 hour= 60 minutes

then, the unit rate is

=1500/60

= 25 cents/ min

Second, P= 25 cents

       

time= 1 minutes

then, the unit rate is

=25/1

= 25 cents/ min

Hence, Call center A and B offers equal wages.
