Answer:
Step-by-step explanation:
Hi!
Lets call:
T = temprature of the object
T₀ = temperature of surroundings
t = time
The rate of change of T is its derivative with respecto to time. If T > T₀, the object looses heat, so T decreases. Then, being k > 0:
In this case T₀ = 70ºF and k = 0.05/min. Then the differential equation is:
Answer:
The missing angle is 41 degrees
Step-by-step explanation:
First of all, a triangle is measured at 180 degrees in total
To find the missing measurement for the third angle, add the 47 and 92 degrees together which would equal 139 degrees.
47+92=139 degrees
Next just subtract 139 from 180 to get your answer.
180-139=41 degrees
The answer is 41 degrees

Answer:
3 45/55 or 3 9/11
Step-by-step explanation:
convert each term to an improper fraction
42/5 divided by -11/5
dividing fractions is the same as multiply by reciprocal of the second term
42/5 x -5/11 = -210/55
