Answer:
The temperature of the weather station was 3 degrees Celcius an hour earlier.
Step-by-step explanation:
We can say that the weather an hour ago should be represented with the variable - x.
From the problem, we know that the temperature of the station falls at a rate of -3 degrees per hour. This means that for every hour, the temperature of the place will go down by about 3 degrees Celsius.
If the temperature of the weather station is currently 0 degrees Celsius, to find its temperature an hour earlier, it means that we will need to add 3 degrees to its current temperature, because that is what must have lost in one hour.
i.e x = 0 + 3 = 3 degrees Celcius.
This means that the temperature of the weather station was 3 degrees Celcius an hour earlier.
Answer:
good
Step-by-step explanation:
4^2•4^4 = 4096
4^6= 4096
Answer: 4^6
12 sessions.
EXPLANATION:
each session is 1 3/4 hours.
We need enough sessions for 21 hours.
the equation is 1 3/4 x f = 21
using the multiplication property of equality, we can do 21 divided by 1 3/4
The answer is 12 sessions.
Hope it helps!
