One quarter has a mass of 5.67 grams. Which is the mass of two rolls of quarters each containing 40 quarters?

9514 1404 393

  453.6 g

Step-by-step explanation:

The mass of 80 quarters will be 80 times the mass of 1 quarter:

  80 × 5.67 g = 453.6 g

The mass of two rolls of quarters is 453.6 grams.

Additional comment

That's about 1.0000 pounds.

-7/8

step-by-step explanation:

instead of subtracting you add the -6/8 and -1/8

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.
