In a model, the distance from the sun to Earth is 7 inches and the distance from the sun to Neptune is 19 inches. If the actual distance from the sun to Earth is 91.549 million miles and the actual distance from the sun to Neptune is 2,780.5 million miles, are the model’s distances proportional to the actual dimensions of the solar system?(1 point)
Responses

Yes, because the ratios can be simplified, and those ratios are equal.
Yes, because the ratios can be simplified, and those ratios are equal.
No, because the ratios of model length to actual distance are different for the two planets.

To find the steps Mario walked per hour, we need to divide the total number of steps (3,600) by the number of hours (24).

3,600 steps / 24 hours = 150 steps per hour

Mario walked 150 steps per hour.

To find the number of acres that will be harvested in 10 hours, we need to calculate the harvest rate per hour and then multiply it by 10.

180 acres / 6 hours = 30 acres per hour

30 acres/hour * 10 hours = 300 acres

The combine machine will harvest 300 acres in 10 hours.

To find the cost per room of the less-expensive company, we need to compare the cost per room for both companies.

Carpet Cleaning Pros charges $40 per room.
Spot on Cleaning charges $300 for six rooms.

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

$300 / 6 rooms = $50 per room

Therefore, the cost per room of the less-expensive company is $40 per room (Carpet Cleaning Pros).

To find out how far the truck could drive with 7 gallons of gasoline, we need to find the average mileage of the truck and then multiply it by the number of gallons.

Average mileage = total distance / total gallons
Average mileage = 120 miles / 5 gallons = 24 miles per gallon

Now, we can calculate how far the truck could drive with 7 gallons of gasoline:
Distance = average mileage * number of gallons
Distance = 24 miles per gallon * 7 gallons = 168 miles

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

To find out how many finches the population grew by each year, we need to divide the total increase in the population (75 finches) by the number of years (3).

Total increase in finch population = 75 finches
Number of years = 3

Increase in finch population per year = total increase / number of years
Increase in finch population per year = 75 finches / 3 years = 25 finches per year

Therefore, the finch population grew by 25 finches each year.
