It rained 464 inches in the rainforest in the last 2 years. On average, how much rain fell in 1 year? $$ inches/year
To find the average amount of rain that fell in 1 year, we divide the total amount of rain that fell in 2 years by 2: 464 inches / 2 years = <<464/2=232>>232 inches/year. Answer: \boxed{232}.
A painter can paint 375 square feet in 3 hours. At this rate, how many square feet can he paint in 7 hours? $$ square feet
To find out how many square feet the painter can paint in 7 hours, we need to set up a proportion.
We know that the painter can paint 375 square feet in 3 hours. Therefore, the rate of painting is 375 square feet / 3 hours = 125 square feet/hour.
We can then use this rate to find out how many square feet the painter can paint in 7 hours:
125 square feet/hour * 7 hours = 875 square feet.
Therefore, the painter can paint 875 square feet in 7 hours. Answer: \boxed{875}.
A scientist is growing bacteria in a beaker. At this rate, in 4 hours, 122 bacteria have grown. How many bacteria will grow in 6 hours? $$ bacteria
To find out how many bacteria will grow in 6 hours, we need to set up a proportion.
We know that in 4 hours, 122 bacteria have grown. Therefore, the growth rate is 122 bacteria / 4 hours = 30.5 bacteria/hour.
We can then use this rate to find out how many bacteria will grow in 6 hours:
30.5 bacteria/hour * 6 hours = 183 bacteria.
Therefore, 183 bacteria will grow in 6 hours. Answer: \boxed{183}.
A town’s population has grown by 3,000 people in the past 6 years. What is the town’s average population growth rate per year? $$ people/year
To find the average population growth rate per year, we divide the total population growth by the number of years:
3000 people / 6 years = 500 people/year.
Therefore, the town's average population growth rate per year is 500 people. Answer: \boxed{500}.
A population of owls in a region has increased by 60 owls in the last 4 years. At this rate, how many owls will the population grow by in the next 2 years? $$ owls
To find out how many owls the population will grow by in the next 2 years, we need to use the given rate.
We know that the population has increased by 60 owls in 4 years. Therefore, the growth rate is 60 owls / 4 years = 15 owls/year.
We can then use this rate to find out how many owls the population will grow by in the next 2 years:
15 owls/year * 2 years = 30 owls.
Therefore, the population will grow by 30 owls in the next 2 years. Answer: \boxed{30}.
To find the average amount of rain that fell in 1 year, we can divide the total amount of rain in 2 years (464 inches) by the number of years (2).
So, the calculation would be: 464 inches / 2 years.
Dividing 464 by 2 gives us the result of 232 inches.
Therefore, on average, 232 inches of rain fell in 1 year.
