Suppose that the diameters of different types of hairs are 1.7 × 10–4 cm, 1.4 × 10–3 cm, 1.2 × 10–5 cm, and 1.9 × 10–4 cm? What is the order of the hairs from least to greatest diameter?
A. 1.9 × 10–4, 1.7 × 10–4, 1.4 × 10–3, 1.2 × 10–5
B. 1.2 × 10–5, 1.7 × 10–4, 1.9 × 10–4, 1.4 × 10–3
C. 1.9 × 10–4, 1.7 × 10–4, 1.2 × 10–5, 1.4 × 10–3
D. 1.2 × 10–5, 1.4 × 10–3, 1.9 × 10–4, 1.7 × 10–4

I shat myself
order them this way: the more positive the exponent, the number is greater.
e means power of ten ) going from least to greatest... e-20, e-9, e-4, e3, e7
when you get two numbers with the same power of ten, you order them by the number expression: 3.4>2.4>1.4>.22
i chose b
correct
ur fav 100% thx
You're welcome! Don't hesitate to ask if you have any more questions or need further assistance.
To find the order of the hairs from least to greatest diameter, we need to compare their diameters and arrange them accordingly.
Let's start by comparing the values before the powers of 10.
1.2 × 10^-5 is the smallest value because the number before the power of 10 is smallest among all the options.
Next, we compare the remaining three values: 1.9 × 10^-4 cm, 1.7 × 10^-4 cm, and 1.4 × 10^-3 cm.
The number before the power of 10 in scientific notation represents the magnitude of the value. In this case, 1.9 is larger than both 1.7 and 1.4. Therefore, the correct order for these three values is:
1.9 × 10^-4, 1.7 × 10^-4, 1.4 × 10^-3
Now, we put the value we found earlier (1.2 × 10^-5) at the beginning:
1.2 × 10^-5, 1.9 × 10^-4, 1.7 × 10^-4, 1.4 × 10^-3
So, the correct order of the hairs from least to greatest diameter is option B:
1.2 × 10–5, 1.7 × 10–4, 1.9 × 10–4, 1.4 × 10–3
