Answer:
Step-by-step explanation:
We are given that
Volume,V=250 L
Mass of salt=m=40 g
Brine containing 1 g per liter
Pumped into the tank at the rate=5 L/min
We have to find the number A(t) of grams of salt in the tank at time t.
Rate of change of salt in the tank
Rate in-Rate out
Rate in=5 L/min
Rate out=
L/min
Using the formula
A=40 and t=0
Substitute the value
Answer:
If it has a diameter of 10, divide it by 2 to get Radius (5) because Area = πr²
Then you do r * π *r which would be 78.5. so C is your answer.

Answer:
Step-by-step explanation:
You only need one, but to use two let's go from cm to mm an then mm to inches. there are 100 mm^2 in a cm^2 so that's 100 mm^2/ 1 cm^2 and then there's 645.16 mm^2 in one square inch so that one will be 1 in^2/ 645.16 mm^2 so writing it out we get:
62 cm^2 * 100 mm^2/ 1 cm^2 * 1 in^2/ 645.16 mm^2
units all cancel out to get in^2 an then you just multiply 62*100/645.16 = 9.61 so that leaves us with 9.61 in^2.
Let me know if there's something you don't understand.
Answer:
i think it would be 10,000
I hope it helped!
