Answer:
There are two types of variables-independent and dependent. ... Answer: An independent variable is exactly what it sounds like. It is a variable that stands alone and isn't changed by the other variables you are trying to measure. For example, someone's age might be an independent variable.

Okay?
Step-by-step explanation:
5. After 6 hours, the concentration is halved. After 12 hours, it will be quartered. If the original concentration is 200 nmol, a quarter is 50 nmol.
14. The population doubles after 3 hours, and a day is 24 hours. That means that the original population should be multiplied by 
, or 
. 3 million times is 3 * 256 million, or 768 million.
15. The concentration is halved every 8 hours and the original concentration is 100 nmol. So now, how many times do you halve 100 to get to 12.5?
100/2 = 50, 50/2 = 25, 25/2 = 12.5. That's three times. 3 * 8 is 24 hours, or 1 day.
Standard form is Ax + By = C. We need to subtract 11y. This gives us 8x + 11y = 24.
The standard form of 8x = -11y + 24 is 8x + 11y = 24.
1-->12, 2*AE = length of the diagonal
3-->10, AC is equal to BD.
2-->
Angles : <CBA, <DBA, <BCD, <BAD, are all 40
Angles: <ADB, <CAD, <ACB, <CBD are all 70
Angles: <ACD, <ABD are 70
Angles: <CDB, CAB are 110.
