Answer:
k = - 6.6667
Step-by-step explanation:
this is quite very simple to begin. I would encourage you take other practice questions similar to help with understanding it.
let us begin.
Given that ;
dT/dt = k ( Tm - T) where Tm is the temp of the medium
dT/dt = 5 degrees Celsius per minute when T = 70
so we have that, 5 = k ( 25 - 70)
remember to convert 5 degree celsius per minute to seconds
we have that;
5*60(sec) = k ( 25 - 70)
k = 5*60 / ( 25 - 70)
k = - 6.6667
note K is negative because we consider it for cooling process (temp decreasing).

Answer:
190 baskets of strawberries
Step-by-step explanation:
The question is incomplete as it didn't state what we are to determine from the information given.
Let's determine total amount picked in the three days.
1st day picked 90strawberries
Amount of strawberries on 2nd day = 2/3 of the amount picked 1st day
= (2/3)(90)
Amount of strawberries on 2nd day = 60 baskets of strawberries
Amount of strawberries picked on 3rd day = (2/3) of the amount picked 2nd day
= (2/3) (60)
Amount of strawberries picked on 3rd day = 40 basket of strawberries
Total amount picked for 3 days = 90+60+40
= 190 baskets of strawberries
