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 10 g, the middle beam has increments of 100 g, and the bottom beam has increments of 1 g.

Step2: Calculate mass for first triple - beam balance

Top beam value = 20 g, middle beam value = 300 g, bottom beam value = 3 g. Total mass = 20 + 300+3 = 323 g.

Step3: Calculate mass for second triple - beam balance

Top beam value = 50 g, middle beam value = 100 g, bottom beam value = 4 g. Total mass = 50 + 100 + 4=154 g.

Step4: Calculate mass for third triple - beam balance

Top beam value = 0 g, middle beam value = 0 g, bottom beam value = 1 g. Total mass = 0+0 + 1=1 g.

Step5: Identify values on four - beam balance

For a four - beam balance, the top beam has increments of 100 g, the second beam has increments of 10 g, the third beam has increments of 1 g, and the bottom beam has increments of 0.1 g.

Step6: Calculate mass for first four - beam balance

Top beam value = 100 g, second beam value = 20 g, third beam value = 8 g, bottom beam value = 0.2 g. Total mass = 100+20 + 8+0.2 = 128.2 g.

Step7: Calculate mass for second four - beam balance

Top beam value = 0 g, second beam value = 50 g, third beam value = 5 g, bottom beam value = 0.5 g. Total mass = 0+50 + 5+0.5 = 55.5 g.

Step8: Calculate mass for third four - beam balance

Top beam value = 0 g, second beam value = 0 g, third beam value = 90 g, bottom beam value = 0.9 g. Total mass = 0+0 + 90+0.9 = 90.9 g.

Answer:

323 g
154 g
1 g
128.2 g
55.5 g
90.9 g
