Step-by-step explanation:
simple
The area covered by the plant increases by 16.66% every month.
Step-by-step explanation:
Step 1; It is given that the plant's area triples every year. So if the plants' area is 100 square feet at the beginning of a year it will be 300 square feet at the end of the year. So there will be an increase of 200% in a year.
Step 2; So to find the increase per month we divide the 200% increase per year by 12 so that it becomes a monthly increase.
Monthly increase =
% = 16.66%. So the tropical plant's area increases by 16.66% each month.
Answer:
The temperature outside is 75.6°F
Step-by-step explanation:
We are given the following in the question:
The temperature of dry ice = - 109.3°F
Let x be the temperature outside in Fahrenheit.
It is given that the temperature of dry ice is 184.9°F less than the outside temperature.
Thus, we can write the equation:

Solving, the above equation, we get:

Thus, the temperature outside is 75.6°F
