Look at the question times it what ever number is listed that is your answer
Answer:
76.09 pounds
Step-by-step explanation:
From the information given:
At a slower of 4 gal/min, the solution gets pumped out;
So,
The differential of the equation is:
For the linear differential equation, the integrating factor is determined as:
Multiplying with the above integration factor;
By using the given condition:
A(0) = 40
40 = 50 + c (50)⁻²
10 = c(50)⁻²
OR
c = -10 × 2500
c = -25000
A = (50 + t) - 25000(50 + t)⁻²
The number of pounds of salt in the tank after 30 min is:
A(30) = (50+30) - 25000(50 + 30)⁻²
Thus, the number of pounds of salt in the tank after 30 min is 76.09 pounds.

Answer:
181 mi^2
Step-by-step explanation:
Dimensions of large rectangle, on the left, are 6 mi by 8 m; area is 48 m^2;
Dimensions of small rectangle, in the middle of the diagram, are 4 mi by 5 mi, or 20 mi^2; area is 20 mi^2.
Dimensions of circle: r = 12 mi; area of quarter circle is (1/4)(3.14)(12 mi)^2, or 113 mi^2.
Total area is 113 mi^2 + 20 mi^2 + 48 mi^2, or 181 mi^2
