The answer is: [B]: " 3.99 * 10⁻⁶ " .
______________________________________________
Note:
______________________________________________
We are given the following answer choices, and we are asked which one is the "smallest number" :
_______________________________________________
[A]: 4.4 * 10⁻⁵
_________________________________________
[B]: 3.99 ⋅ 10⁻⁶
______________________
[C]: 2.6 ⋅ 10²
______________________
[D]: 1.85 ⋅ 10³
_______________________
We can rule out answer choices: [C] and [D]; since these values, essentially "direct us" to move the decimal point FORWARD "2 places" and "3 places", respectively; whereas choices [A] and [B] essentially "direct us" to move the decimal point BACKWARD "5 places" and "6 places" respectively. Note that all values given in the answer choices are written in proper "scientific notation" —that is, beginning with a "single integer followed by (a) decimal point(s) and then additional digits (when needed). So, the answer choice that essentially "directs us" to move the decimal point BACKWARD "6 places" —

→ Answer choice: [B]: " 3.99 * 10⁻⁶ " ;

is the smallest value ; and as such, the correct answer.

If this is for a rectangle the volume of it would be 39/2 or 19 1/2
Hello,
We must calculate the volume of water in one hour.
V=15000*PI*0.07²=230,9070600... m^3/h.
Volume of the pond=50*44*.21=462 m^3
Time=462 m^3/ 230.907... m^3/h=2,0008... h≈2 h
Answer:
Step-by-step explanation:
step 2 is always exponets so 6 squared divided by 8
Answer: 40%
Step-by-step explanation:
Total students= 240
Dissatisfied students= 96
To get the percentage of sixth grade students that were dissatisfied with the music played in the school, we divide 96 by 240 and multiply the result by 100. This can be written as:
= 96/240 × 100
= 0.4 × 100
= 40%
The percentage represented is 40%
