Answer:
50x105m
Step-by-step explanation:
310 (length of field) - 65-65= 200/4=50
Start with the perimeter subtract 65 twice because the length is on two sides. Now the length and width will be equal so divide by 4. Add 65 back because you subtracted it earlier.
Answer:
a) 
: at time t = 2 minutes the temperature will be 8.265 degress
b) 
: the temperature will be 6 degrees at time t = 3.55 minutes.
Step-by-step explanation:
When dealing with temperature changes, it's best to work with Newton's Law of Cooling.
here:
: the temperature in the room.
: ambient (or outdoor) temperature (that always remains constant, in our case: 
)
: are constants
Our conditions are provided:
1) 
2) 
using the first condition
using the second condition:
we can use our calculated value of C to find k
Finally we can put these constants back in the main equation:
or 
a) Reading after one more minute?
so it's asking:
T(2) = ?
Hence, after one more minute the temperature of the room will be 8.267 degrees
b) When will it be 6 degrees?
T(t) = 6?
Hence at t = 3.55 minutes the temperature of the room will be 6 degrees.

Answer:
It would represent 116.66666667
Step-by-step explanation:
3 inches= 50 miles
1 inch = 50/3 miles
7 inches = 50/3 × 7 miles
= 116.66666667 miles
