Apower plant generates electricity by burning oil. pollutants produced as a result of the burning process are re- moved by scrubbers in the smokestacks.
over time, the scrubbers become less efficient and eventually they must be replaced when the amount of pollution released exceeds government standards.
measurements are taken at the end of each month determining the rate at which pollutants are released into the atmosphere, recorded as follows. month
pollutant release rate (tons> day)

pollutant release rate (tons> day)

a. assuming a 30-day month and that new scrubbers allow only 0.05 ton> day released, give an upper estimate of the total tonnage of pollutants released by the end of june. what is a lower estimate? b. in the best case, approximately when will a total of 125 tons of pollutants have been released into the atmosphere?

answer:

step-by-step explanation:

answer: a.   one is a factor of every whole number since every number is divisible by itself.

14

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.
