A large mixing tank initially contains 1000 gallons of water in which 40 pounds of salt have been dissolved. Another brine solution is pumped into the tank at the rate of 5 gallons per minute, and the resulting mixture is pumped out at the same rate. The concentration of the incoming brine solution is 3 pounds of salt per gallon. If img represents the amount of salt in the tank at time t, the correct differential equation for A is:______.
A) dA/dT=3--.005A
B) dA/dT=5--.05A
C) dA/dT=15--.005A
D) dA/dT=3--.05A
E) dA/dT=15+.05A

Answers

Answer:

If A(t) represents the amount of salt in the tank at time t, the correct differential equation for A is is dA/dt =  15 - 0.005A

Option C) dA/dt =  15 - 0.005A is the correction Answer

Step-by-step explanation:

Given the data in the question;

If A(t) represents the amount of salt in the tank at time t, the correct differential equation for A is?

dA/dt = rate in - rate out

first we determine the rate in and rate out;

rate in = 3pound/gallon × 5gallons/min = 15 pound/min

rate out = A pounds/1000gallons × 5gallons/min  = 5Ag/1000pounds/min

= 0.005A pounds/min

so we substitute

dA/dt = rate in - rate out

dA/dt =  15 - 0.005A

Therefore, If A(t) represents the amount of salt in the tank at time t, the correct differential equation for A is is dA/dt =  15 - 0.005A

Option C) dA/dt =  15 - 0.005A is the correction Answer

what is the range of the data below 6.5,7.6,9.1,2.4,8.8​

Answers

Answer:

the range would be 6.7 or if you want it to be rounded up, it would be 7.

Step-by-step explanation:

you subtract the highest number by the lowest number. 9.1-2.4= 6.7 or if you need it to be rounded, 7.

The range of the data set given is 6.7.

What is range in statistics?

In statistics, the range of a set of data is the difference between the largest and smallest values, the result of subtracting the sample maximum and minimum. It is expressed in the same units as the data.

Given is a data set, we need to find the range of the data set,

S = 6.5, 7.6, 9.1, 2.4, 8.8​

The range = max value - min value

= 9.1 - 2.4 = 6.7

Hence, the range of the data set given is 6.7.

The difference of two numbers is 63. The sum of two numbers is 111. What are the two numbers?

Answers

Answer:

Step-by-step explanation:

Let b>a

b-a=63

b=63+a

a+b=111, substituting 63+a from above in this equation gives you

a+63+a=111

2a+63=111

2a=48

a=24, since b=63+a

b=63+24

b=87 so the two numbers are

24 and 87

Answer:

Step-by-step explanation:

I assume that they want the value of a when the solution exists.

2(ax+3y)+2x-6y=2(-5)+10

2ax+6y+2x-6y=-10+10

2ax+2x=0

ax+x=0

ax=-x

a=-1

You could then solve for x and y if you wanted x=5 and y=0

Answers

Answer:

3 2/5 cups remaining

Step-by-step explanation:

To subtract fractions, they need a common denominator. I am using 5.

7 is equal to 35/5. Make 3-3/5 into an improper fraction of 18/5.

Now subtract: 35 - 18 = 17. There is 17/5 remaining.

Make it into a mixed number and you will get 3 2/5 remaining.
