Answer:

99

Step-by-step explanation:

8 + 7(4^2 - 3)

Solve what’s in the parentheses first, starting with 4^2:

8 + 7(16 - 3)

Continue solving what’s in the parentheses:

8 + 7(13)

Considering the order of operations, multiply 7(13) before adding 8:

8 + 91 = 99

padilas [110]

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.
