very large tank initially contains 100 kg of 60% brine (60 wt% salt in water). At the start of a process, an inlet stream of 10 kg/min of a 10% brine solution begins flowing into the tank. Solution also begins to drain out of the tank at a rate of 15 kg/min. Assume complete mixing. Calculate the mass of salt (in kg) in the tank after 10 minutes.

answer: howdy

step-by-step explanation:

i dont know men

step-by-step explanation:

solution:

we have to construct

∠m nt ≅ ∠p qr

the steps to draw this construction are

step 1: use a compass to draw an arc from point q which intersects the side pq at point a and the side qr at point b.

step 2: draw a segment nt and use the same width of the compass to draw an arc from point n which intersects the segment nt at a point x.

step 3:

step 4: join points n and y using a straightedge.

step 3:

option (d).maintaining the same width of the compass as ab, draw an arc from point x such that it intersects the arc drawn from n in a point y.

to draw   congruent angles , 1. width of compasses while drawing two angles should be same i.e from point at which angle has to be drawn, 2.the distance between the two points where the compass intersects the two sides should be same while drawing any two congruent angles.
