Answer:
the answer is C, 369
Step-by-step explanation:
1. divide 800 by 40 which will give you 20
2. then multiply 18 by 20
3. answer is 360
the reason I did this was because if you had multiplied math, physics and chemistry by 20 it would have given you the total of 800 trials

Answer:
2998 ; 17%
Step-by-step explanation:
Given the function:
t(c)=-3970.9(ln c)
c = % of carbon remaining ; t = time
1.) c = 47% = 47/100 = 0.47
t(0.47) = - 3970.9(In 0.47)
t = - 3970.9 * −0.755022
t = 2998.119
t = 2998
B.)
t = 7000
t(c)=-3970.9(ln c)
7000 = - 3970.9(In c)
7000 / - 3970.9 = In c
−1.762824 = In c
c = exp(−1.762824)
c = 0.1715596
c = 0.1715596 * 100%
c = 17.156% ; c = 17%
When you line the object up against the ruler you are measuring it's side, if you put it on the one instead of the zero then you're making the object one inch longer, so you'd have to subtract the one in the end
Answer:
C equals 56.25
Step-by-step explanation: because all we have to do is 225 divided by 4. Hope this helps and can you make me brainliest. :)
, your answer will be in seconds. So divide your distance (2.28 x 10^11 meters) by your speed (3.00 x 10^8 meters/second), and you should get your time!
