You are hosting a dinner party tonight and you forget to put the soda bottle into the refrigerator so take a bottle of soda at room temperature which is 70°F and put it in the river refrigerator to cool hoping that it will be cold but a time your guest arrive the temperature in the refrigerator is 40°F in K equals 0.4 what will the temperature be in one hour two hours and three hours

T=R + (T0-R)e-kt so after 1 hour: T = 40°F + (70°F -40°F)e-0.4*1 = 60.11°F

After 2 hours: T = 40°F + (70°F -40°F)e-0.4*2 = 53.48°F

After 3 hours: T = 40°F + (70°F -40°F)e-0.4*3 = 49.04°F

Step-by-step explanation:

Pluto answer

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6

none cuz there are no "following statements" regarding the question
