Answer:
n/-8 = 7
Step-by-step explanation:
n is the number, being divided by -8 and it equals 7
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.
Opposite sides are congruent in a parallelogram.
so,
JK will be congruent with ML
and
JM will be congruent with KL

Answer:
3 necklaces.
Step-by-step explanation:
According to the Question,
Elise is having 15 Purple beads and 12 Yellow beads ,
All necklace should be the same ,
So, She wants to form group such that in each group , equal number of Purple and Yellow beads will be present.
Now , the maximum number of such necklaces can be calculated from the HCF of 15 and 12 as we want to break them in equal groups .
Now , HCF of 15 and 12 comes out to be 3.
Thus ,
a maximum of 3 necklaces can be made.
