So he worked 30.5 hours, he just didn't write some of the hours down. To find the hours he didn't write down, you subtract 8+
+
from 30.5, which equals
Answer:
m cm3
n= cm2df
Step-by-step explanation:
Ln(6)=ln(3^2)=2*ln(3)
so 2*ln(6) = 4*ln(3)
so 2*ln(6) - ln(3) = 3*ln(3)
133=x + (x+5) + (x+14)
133 = 3x+19
3x=114
x= 114/3 =38
5+38 =43
38+14 =52
check: 38 +43 +52 = 133
3 sides are : 38, 43 & 52
First of all, you have to find the common difference between the numbers. That will be;
3/4-3/8=1 1/2-1 1/8
In the case of 1 1/2-1 1/8, the two whole numbers will subtract each other(1-1)
That will leave you with 1/2-1/8
3/4-3/8=1/2-1/8
The common denominator in both cases is 8
In 3/4-3/8
Divide 8 by 4 and multiply by 3 which will be 6
Divide 8 by 8 and multiply by 3. That will be 3
So you have; 6-3/8
Which is 3/8
If you do the same to 1/2-1/8, you will still end up with 3/8
Next, to find the fraction required to make 6 batches, you need to add 3/8 to the last term to the last term
1 1/2+3/8
3/2+3/8=12+3/8
15/8. This is the fifth batch. Add 3/8 again to get the sixth batch
15/8+3/8=15+3/8
18/8
Which is 9/4 when divided. The sixth batch is 9/4 or 2 1/4 in mixed fraction
Hope that helped. Have a nice day
