Lilit [14]

Answer:

<em>The maximum number of kilowatt-hours is 235</em>

Step-by-step explanation:

<u>Inequalities</u>

Robert's monthly utility budget is represented by the inequality:

0.1116x + 23.77 < 50

Where x is the number of kilowatts of electricity used.

We are required to find the maximum number of kilowatts-hours used without going over the monthly budget. Solve the above inequality:

0.1116x + 23.77 < 50

Subtracting 23.77:

0.1116x < 50 - 23.77

0.1116x < 26.23

Dividing by 0.1116:

x < 26.23/0.1116

x < 235

The maximum number of kilowatt-hours is 235

To find:

The ratio of the afternoon to morning.

Afternoon Temperature = 30 degrees

\text{Ratio}=\dfrac{\text{Afternoon Temperature}}{\text{Morning Temperature}}

\text{Ratio}=\dfrac{30}{15}

\text{Ratio}=\dfrac{2}{1}
