Answer:

17 inches

Step-by-step explanation:

Given

P = 51 --- Perimeter of rectangle

Required

The length of the original square

The perimeter is calculated as

51 = 2(L + W)

Divide by 2

25.5 = L + W

The rectangle and the square have the same length.

So:

L = 2W

25.5 = L + W becomes

25.5 = 2W + W

25.5 = 3W

Divide both sides by 3

W = 8.5

Recall that:

L = 2W

L = 2 * 8.5

L = 17

Suppose that a large mixing tank initially holds 900 gallons of water in which 50 pounds of salt have been dissolved. Another br
borishaifa [10]

Answer:

dA/dt= 12-2A(t)/900+t

Step by step Explanation:

Given:

rate of 3 gal/min

concentration of the solution entering is 4 lb/gal,

The equation of the solution can be expressed as

dA/dt = R(1)- R(2)

Where R(1)=( concentration of the salt at inflow* rate of input of given brine)

R(2)= ( concentration of the salt at inflow* rate of output of given brine)

R(1)= 3 gal/min× 4 lb/gal=12Ib/min

But the solution is been pumped slowly, the rate of the accumulation can calculated as;

(3 gal/min- 2 gal/min)=1gal/min

But after t min we will be having 900+t gallons present in the tank
