Cutting down trees leads to deforestation, which in turn results in an increase in greenhouse gas emissions. Trees serve as natural carbon sinks, absorbing carbon dioxide from the atmosphere and storing it in their biomass. When trees are cut down, this stored carbon is released into the atmosphere, contributing to the greenhouse effect and global warming. Additionally, deforestation reduces the Earth's capacity to absorb carbon dioxide, further exacerbating climate change.

At a concert, 300 patrons enter the gates in 30 minutes. What is the unit rate in patrons per minute?(1 point)
To find the unit rate, we divide the total number of patrons by the total number of minutes.
Unit rate = 300 patrons / 30 minutes = 10 patrons per minute
Unit rate = 300 patrons / 30 minutes = 10 patrons per minute
Bird seed costs $4.80 for a 32-ounce bag. What is the unit cost of the bird seed per ounce?(1 point
To find the unit cost per ounce, we divide the total cost by the total weight.
Unit cost per ounce = $4.80 / 32 ounces
Simplifying the expression, we have:
Unit cost per ounce = $0.15 per ounce
Unit cost per ounce = $4.80 / 32 ounces
Simplifying the expression, we have:
Unit cost per ounce = $0.15 per ounce
A lake has 16 boats in 4 square miles. Determine the unit rate in boats per square mile.(1 point)
To find the unit rate, we divide the total number of boats by the total area in square miles.
Unit rate = 16 boats / 4 square miles = 4 boats per square mile.
Unit rate = 16 boats / 4 square miles = 4 boats per square mile.
An investor bought 800 acres of land for $2,000,000. How much is the cost per acre?(1 point)
To find the cost per acre, we divide the total cost by the total number of acres.
Cost per acre = $2,000,000 / 800 acres
Simplifying the expression, we have:
Cost per acre = $2,500 per acre
Cost per acre = $2,000,000 / 800 acres
Simplifying the expression, we have:
Cost per acre = $2,500 per acre
Sonia bought 15 pounds of candies to give away for Halloween. She paid $25 for the candies. What is the cost per pound?(1 point)
To find the cost per pound, we divide the total cost by the total weight.
Cost per pound = $25 / 15 pounds
Simplifying the expression, we have:
Cost per pound = $1.67 per pound
Cost per pound = $25 / 15 pounds
Simplifying the expression, we have:
Cost per pound = $1.67 per pound

The forest loses 6 old-growth trees per 100 years.
The forest has 1 old-growth tree per acre.
To determine the conclusion the biologist can make about the forest, we need to calculate the number of old-growth trees per acre.
Number of old-growth trees per acre = Total number of trees / Total number of acres
Number of old-growth trees per acre = 600 trees / 100 acres
Simplifying the expression, we have:
Number of old-growth trees per acre = 6 old-growth trees per acre.
Therefore, the conclusion the biologist can make is that the forest has 6 old-growth trees per acre.
Number of old-growth trees per acre = Total number of trees / Total number of acres
Number of old-growth trees per acre = 600 trees / 100 acres
Simplifying the expression, we have:
Number of old-growth trees per acre = 6 old-growth trees per acre.
Therefore, the conclusion the biologist can make is that the forest has 6 old-growth trees per acre.

To determine the speed of light as the unit rate in millions of miles per minute, we divide the total distance by the total time.
Speed of light = 93 million miles / 8 minutes
Simplifying the expression, we have:
Speed of light = 11.6 million miles per minute
Therefore, the approximate speed of light is 11.6 million miles per minute.
Speed of light = 93 million miles / 8 minutes
Simplifying the expression, we have:
Speed of light = 11.6 million miles per minute
Therefore, the approximate speed of light is 11.6 million miles per minute.
