The Young family and the Parker family each used their sprinklers last summer. The water output rate for the young family's sprinkler was 30 L per hour. The
water output rate for the Parker family's sprinkler was 25 L per hour. The families used their sprinklers for a combined total of 65 hours, resulting in a total
water output of 1825 L. How long was each sprinkler used?
Note that the ALEKS graphing calculator can be used to make computations easier.

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.

answer: 8

step-by-step explanation: if you add the possibilities 5 different flavor and 3 different sizes 5+3=8
