a total of eight pills are on a table. all have the same color and size. however, one is poisonous and weighs a fraction more than the others. a balance scale may be used only two times to determine the heavier pill. seven of the pills must be eaten.
What's your question? All you would do is weigh each one and write down the weights. The heaviest one would not get eaten and the others would.
um, your right, you didn't understand the question. first off, its a balance scale, which doesn't tell you the weights, and secondly, you can only use the scale 2 times, not seven.
how would you make 300,000+40,000+800 into a standard notation
To determine the heavier pill among the eight pills on the table, you can follow these steps:
Step 1: Divide the pills into three groups.
Group 1: Place three pills on one side of the balance scale.
Group 2: Place three pills on the other side of the balance scale.
Remaining Group: Keep two pills aside.
Step 2: Weigh the two groups against each other.
Case 1: If the scale is balanced, the heavier pill is in the remaining group of two. Proceed to Step 3.
Case 2: If the scale is not balanced, go to Step 3 directly.
Step 3: Take the remaining group of two pills from the previous step and choose one of the pills. Weigh this pill against any other pill from the group of two on the balance scale.
Case 1: If the scale is balanced, the remaining pill is the heavier one.
Case 2: If the scale is not balanced, the scale will tilt towards the side with the heavier pill.
By following these steps, you can identify the heavier pill using the balance scale only two times.
