After sitting in a refrigerator for a while, a turkey at a temperature of 34 degrees F is placed on the counter and slowly warms
Anton [14]

Answer:

  • k = 0.006
  • T = 48 °F

Step-by-step explanation:

The initial temperature difference of 72 -34 = 38 °F is reduced to a difference of 72 -41 = 31 °F after 35 minutes. The exponential term in the temperature expression could have the factor ...

  (31/38)^(t/35) = e^(-kt)

Taking the natural log, we find ...

  (t/35)ln(31/38) = -kt

  k = ln(38/31)/35 ≈ 0.00581711

To the nearest thousandth, this is ...

  k ≈ 0.006

Using this in the equation for temperature, we have ...

  T = 72 -38e^(-0.006t)

Filling in the desired value for t (80), we find the turkey temperature after 80 minutes to be about

  T = 72 -38e^(-.006×80) = 72 -38e^-.48 ≈ 48.49

  T ≈ 48 °F

The value of k is about 0.006, and the turkey temperature is about 48 °F.

The ratio of the number of left-handed batters to the number of right handed batters is 5:8. There are 45 left-handed batters. f
Anuta_ua [19.1K]
Answer=15:39

Step1(find the number of right handed batters)

Left-handed batters=45

 5    45
__=___
8      x


Cross multiply
5x=360
divide both sides by 5
x=72
Right-handed batters=72

Step 2 (find the number of total batters)
total batters=45+72=117

Step3 (find the ratio of left handed batters to total batters)

Left-handed batters to total batters= 45/117
45/117 can be shortened to 15/39

Answer=15:39
