Answer:
The number times both Mark and Jen will be at the beach on the same day over the next 30 days is 10 times.
Step-by-step explanation:
Every third day implies that they both go the beach and then have a two day break, and then go the beach on the day after.
Put simply, every third day implies one day in three days.
Based on the above, the number times both Mark and Jen will be at the beach on the same day over the next 30 days can be calculated by dividing 30 by 3 as follows:
Number times both Mark and Jen will be at the beach = 30 / 3 = 10
Therefore, the number times both Mark and Jen will be at the beach on the same day over the next 30 days is 10 times.
Answer:
Sewage treatment and nitrous oxide
Step-by-step explanation:
Sewage to treatment and nitrous oxide is correctly paired with the greenhouse gases that it increases.
Greenhouse gas refers to gases that has the property of absorbing infrared radiation (net heat energy) emitted from Earth’s surface and reradiating it back to Earth’s surface, thus contributing to the greenhouse effect.
Examples of greenhouse gases and the most important greenhouse gases are methane, carbon dioxide (CO2), and water vapor.
Human activities such as fossil-fuel combustion are responsible for increase in the atmospheric concentration of various greenhouse gases, especially carbon dioxide, methane and ozone.
