Question

what masses are shown on each of the following balances? triple beam balance four beam balance

Explanation:

Step1: Identify values on triple - beam balance

For a triple - beam balance, the top beam has increments of 1 g, the middle beam has increments of 10 g, and the bottom beam has increments of 100 g. For the first triple - beam balance:
The top beam reads 2.8 g, the middle beam reads 20 g, and the bottom beam reads 600 g.

Step2: Calculate total mass

Total mass = 600 + 20+2.8=622.8 g

For the second triple - beam balance:
The top beam reads 3.6 g, the middle beam reads 10 g, and the bottom beam reads 500 g.
Total mass = 500 + 10+3.6 = 513.6 g

For the third triple - beam balance:
The top beam reads 0.4 g, the middle beam reads 10 g, and the bottom beam reads 0 g.
Total mass = 0+10 + 0.4=10.4 g

For the four - beam balance:
The top beam has increments of 0.1 g, the second beam has increments of 1 g, the third beam has increments of 10 g, and the fourth beam has increments of 100 g.
For the first four - beam balance:
The top beam reads 0.2 g, the second beam reads 2 g, the third beam reads 20 g, and the fourth beam reads 100 g.
Total mass = 100+20 + 2+0.2=122.2 g

For the second four - beam balance:
The top beam reads 0.5 g, the second beam reads 5 g, the third beam reads 50 g, and the fourth beam reads 200 g.
Total mass = 200+50 + 5+0.5=255.5 g

For the third four - beam balance:
The top beam reads 0.9 g, the second beam reads 0 g, the third beam reads 90 g, and the fourth beam reads 0 g.
Total mass = 0+90+0 + 0.9=90.9 g

Answer:

622.8 g
513.6 g
10.4 g
122.2 g
255.5 g
90.9 g
