The weights of four different insects are given below.
Insect A: 2.19*10^-4 g;
Insect B: 5.00*10^-3 g;
Insect C: 9.0*10^-2 g;
Insect D: 1.50*10^-3 g
What is the order of these insects from heaviest to lightest?
Use 10^-4 as a common exponent. Then they are, as multiples of 10^-4:
2.19
50.0
900.0
15.0
Not too hard to order them now, eh?
To determine the order of the insects from heaviest to lightest, we will compare the weights of each insect.
Given weights:
Insect A: 2.19 * 10^-4 g
Insect B: 5.00 * 10^-3 g
Insect C: 9.0 * 10^-2 g
Insect D: 1.50 * 10^-3 g
First, let's convert the weights to a common unit, like grams, for easier comparison.
Insect A: 2.19 * 10^-4 g
Insect B: 5.00 * 10^-3 g
Insect C: 9.0 * 10^-2 g
Insect D: 1.50 * 10^-3 g
Converting using scientific notation:
Insect A: 0.000219 g
Insect B: 0.005 g
Insect C: 0.09 g
Insect D: 0.0015 g
Now, comparing the weights, we can determine the order:
Insect C (0.09 g)
Insect B (0.005 g)
Insect D (0.0015 g)
Insect A (0.000219 g)
So, the order of the insects from heaviest to lightest is: C, B, D, A.
