Answer:
<u>The table shows that:</u>
- The value of y decreases when the value of x decreases or vice versa, the value of y increases as x increases.
Therefore the line has a positive slope
Answer:
B = (C-Ax)/y
Step-by-step explanation:
Solve for B.
Ax+By=C
making B the subject of formula '
Ax+By=C
subtract Ax from both sides
By = C-Ax
By = C-Ax
divide both sides by y
B = (C-Ax)/y
Answer is A, y = 65
The top angle is 50 because 180 - 130 = 50
Since the top angle is 50, the two bottom angles have to add up to 130. Since the bottom angles are the same, you can do 130 / 2 to find the angles which equals 65.
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.
Answer:
B
Step-by-step explanation:
if it is shaded under than it is <
the slope is 1/2x so that is the answer
