Answer:
A.) 0.0129 = k
B.) 2024
Step-by-step explanation:
A.)
267,000 = 250,300e^k5
267,000/250,300 = e^k5
1.0667 = e^k5
ln(1.0667) = lne^k5
ln(1.0667) = 5k
ln(1.0667)/5 = k
0.0129 = k
B.)
300,000 = 250,300^0.0129t
300,000/250,300 = e^0.0129t
1.1986 = e^0.0129t
ln(1.1986) = lne^0.0129t
ln(1.1986) = 0.0129t
ln(1.1986)/0.0129 = t
14.03 = t
so the year would be: 2024
Answer:
5
Step-by-step explanation:
If you mean a whole, sorry if its incorrect
Apples went up 0.75 a lb
p is the start price so new price is p + 0.75
we buy 3 lbs
3 ( p+ 0.75) = 5.88
now solve
3p + 2.25 = 5.88
-2.25 -2.25
3p = 3.63
/3 /3
p = 1.21 a lb
Answer:
1a. 1.5
1b. 0.38
Step-by-step explanation:
a.
one full grid is full (1) and half a grid is full (0.5)
b.
there are 100 squares and 38 of them are filled in,so you divide 38 by 100 which is 0.38
Answer:
The amount of water must be added to this task = 60 
Step-by-step explanation:
Let amount of water added = x
Then from the given conditions
A chemist would like to dilute a 90-cc solution that is 5% acid to one that is 3% acid. So
90 (0.05) = 0.03 ( 90 + x )
4.5 = 2.7 + 0.03 x
0.03 x = 1.8
x = 60
Therefore the amount of water must be added to this task = 60
