Using separation of variables, it is found that the expression for the mass, M, at any time t, is given by:
<h3>What is separation of variables?</h3>
In separation of variables, supposing a differential equation in the format , we place all the factors of y on one side of the equation with dy, all the factors of x on the other side with dx, and integrate both sides.
In this problem, the differential equation is:
Then, applying separation of variables:
The initial mass is of M(0) = 150, hence:

Answer:
1.25 cups of diced tomatoes
Step-by-step explanation:
1. 12 1/4 ÷ 7
2. = 49/4 x 1/7
3. =49/28
4. =7/4
5. =1 1/4 or 1.25

Answer:
Keith spent 37 and a half minutes dusting.
Step-by-step explanation:
Given that Keith spent 2 1/2 of hours doing chores, and I have spent 1/4 of that time dusting, to determine how much time did Keith spend dusting, the following calculation must be performed:
1/2 = 0.5
1/4 = 0.25
2.5 x 0.25 = X
0.625 = X
1 = 60
0.625 = X
0.625 x 60 = X
37.5 = X
Therefore, Keith spent 37 and a half minutes dusting.
0.7 is just 7 tenths which is literally 7/10.
