Answer:
x = -4.604
Step-by-step explanation:
Here, we want to get the value of x
We start by dividing through by 5
e^(2x + 11) = 30/5
e^(2x + 11) = 6
Writing this in natural logarithm form, we have;
ln 6 = 2x + 11
2x + 11 = 1.792
2x = 1.792-11
2x = -9.208
x = -9.208/2
x = -4.604
Given:
Louise used 0.61 kilogram of flour each day for 3 weeks.
To find:
How many grams did Louise use in those 3 weeks?
Solution:
We know that,
1 kg = 1000 g
Flour used by Louise each day for 3 weeks = 0.61 kg
1 week = 7 days
3 week = 21 days
Flour used by Louise for 3 weeks (21 days) = (21 × 0.61) kg
= 12.81 kg
= (12.81 × 1000) [ 1 kg = 1000 g]
= 12810 g
Therefore, flour used by Louise for those 3 weeks is 12,810 grams.
The mug cost $12 as it is, so first you subtract 12 from 34, which is 22. From there, you divide 22 by 2.20, which would be 10. Therefore, she can get a mug and 10 refills for $34.
There’s 4 oxygen as O2 is multiplied by 2 as there are 2 groups of c2h3o2 present.
