Answer 6

To find the cost per room for Spot on Cleaning, we can divide the total charge by the number of rooms.

Spot on Cleaning charges $300 for 6 rooms:
Cost per room = Total charge / Number of rooms = $300 / 6 = $50 per room.

Now, we compare the costs:

- Carpet Cleaning Pros: $40 per room
- Spot on Cleaning: $50 per room

The less-expensive company is Carpet Cleaning Pros, with a cost of:

**$40/room**

Answer 7

First, we need to determine the truck's fuel efficiency (miles per gallon).

The truck drives 120 miles using 5 gallons of gasoline. Therefore, the miles per gallon (MPG) is calculated as follows:

\[
\text{MPG} = \frac{\text{Miles Driven}}{\text{Gallons Used}} = \frac{120 \text{ miles}}{5 \text{ gallons}} = 24 \text{ miles per gallon}
\]

Now, to find out how far the truck could drive with 7 gallons of gasoline, we multiply the MPG by the number of gallons:

\[
\text{Distance with 7 gallons} = \text{MPG} \times \text{Gallons} = 24 \text{ miles per gallon} \times 7 \text{ gallons} = 168 \text{ miles}
\]

So, the truck could drive **168 miles** with 7 gallons of gasoline.

Answer 8

To find out how many finches the population grew by each year, we can divide the total increase in the finch population by the number of years.

The total increase is 75 finches over 3 years.

\[
\text{Annual increase} = \frac{\text{Total increase}}{\text{Number of years}} = \frac{75 \text{ finches}}{3 \text{ years}} = 25 \text{ finches/year}
\]

Thus, the population grew by **25 finches** each year.

Answer 9

To compare the lengths, we can convert all the units to the same measurement (meters) for clarity:

1. **One yard**:
- 1 yard = 0.9144 meters

2. **One kilometer**:
- 1 kilometer = 1000 meters

3. **One meter**:
- 1 meter = 1 meter

4. **One inch**:
- 1 inch = 0.0254 meters

Now let's summarize the lengths in meters:
- One yard = 0.9144 meters
- One kilometer = 1000 meters
- One meter = 1 meter
- One inch = 0.0254 meters

From this comparison, it's clear that **one kilometer** is the longest length.

Answer 10

The measurement that is used in the metric system is **kilogram**.

The other options, yard, mile, and gallon, are part of the imperial system of measurements.
