Answer:
The mode is 7
Step-by-step explanation:
Answer:
1. 516 ppm; 2. 561 ppm
Step-by-step explanation:
1. CO₂ increase at old rate
Time = 2100 - 2010 = 90 years
Increase in CO₂ = 90 yr × (1.4 ppm/1 yr) = 126 ppm
CO₂ in 2010 = 390 + 126 = 516 ppm
At the old rate, the CO₂ concentration in 2100 will be 516 ppm.
2. CO₂ increase at new rate
Time = 2100 - 2010 = 90 years
Increase in CO₂ = 90 yr × (1.9 ppm/1 yr) = 171 ppm
CO₂ in 2010 = 390 + 171 = 561 ppm
At the new rate, the CO₂ concentration in 2100 will be 561 ppm.
41-28=13 questions, but you also have to do 41 and 28, so 15 questions
Answer:
read the question and you will find the like the question and just find it out The weather report says the temperature is 20°c and will drop 5°c per hour for the next 6 hours.
Temperature drops by 5°c per hour
So we find the temperature after 6 hours
In 1 hour temperature drops= 5°c
So in 6 hours = 6* 5 = 30°c
In 6 hours , temperature drops by 30°c
the actual temperature is 20°c. after 6 hours the temperature becomes
20°c - 30°c= -10°c
So, after 6 hours the temperature will be -10°c
Daryl plans to be gone for at least 6 hours. so its 6 hours or more than 6 hours
In 6 hours or more than 6 hours , the temperature will drop less than -10°c
