Mathematics

Elena-2011 [213]3 years ago
4 0

Step-by-step explanation:

Here's the first question and how to solve the second.

So the first business start with 250, that's your b in slope.

y = mx + b

y = mx + 250

Now, they charge 14 an hour so that's your m.

y = 14x + 250

x is the number of hours it takes.

The second business is straight up 22 per hour, so it's just y = mx, where b is 0.

y = 22x VS y = 14x + 250

Try plugging in different numbers and seeing how much it take to level out!

Suppose the population of a certain city is 5831 thousand. It is expected to decrease to 5204 thousand in 50 years. Find the per
SVEN [57.7K]

Answer:

The percent decrease is approximately 10.75\%

(Don't know what you are expected to round to.)

Step-by-step explanation:

Percent change can be calculated by doing:

\frac{\text{original}-\text{new}}{\text{original}}

Then you multiply the result to covert it to a percentage.

Let's use this formula:

\frac{5831 \text{thousand}-5204 \text{ thousand }}{5831 \text{thousand}}

\frac{\text{thousand}}{\text{thousand}} \cdot \frac{5831-5204}{5831}

\frac{5831-5204}{5831}

\frac{627}{5831}

0.1075 approximately

Now the answer as a percent is 10.75\% approximately.

The percent decrease is approximately 10.75\%
