Answer:
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.

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
Answer:
Triangles ABC and DEF have the following characteristics :B and E are right angles A=D, BC=EF which congruence theorem can be used to prove ABC =DEF
5 gerbils = p dollars
1 gerbil = p/5 dollars
g gerbils = pg / 5 dollars
5/p gerbils = 1 dollar
5d/p gerbils = d dollars
