Answer:
76.25°
Step-by-step explanation:
The solution to the differential equation is an exponential curve with a horizontal asymptote at Tm. It passes through (0, 145) and (30, 95), so the equation can be written as ...
T = 80 +65((95-65)/(145-65))^(t/30)
T = 80 +65(3/8)^(t/30)
That is, the temperature difference is reduced to 3/8 of its original value in 30 minutes.
Since the coffee in cup B cools twice as fast, it will cool to the same temperature (95°) in 15 minutes. In the next 15 minutes, the temperature difference will be reduced to (3/8)^2 of the original 80°, so will be 11.25°. That is, the temperature of cup B will be ...
11.25° +65° = 76.25°
after 30 minutes.
Answer:
x = 14.04°
Step-by-step explanation:
Find x using the tangent ratio in the right triangle, that is
tan x = =
=
Hence
x = (0.25) = 14.04°
X would equal = 3 because -
+ 8 x 3 = 33.
9 + 24 = 33.
Hope this helps (:
9 + 24 = 33.
