Answer:
ln(108) = 3.58
Step-by-step explanation:
Data provided:
ln(2) ≈ 0.69
and
ln(3) ≈ 1.10
equation to be solved
ln(108)
now,
ln(108) = ln (2 × 54)
or
= ln( 2 × 2 × 27 )
or
= ln( 2 × 2 × 3 × 3 × 3 )
or
= ln( 2² × 3³ )
Now,
we have the property of log function as:
1) ln(AB) = ln(A) + ln(B)
and,
2) ln(xⁿ) = n × ln(x)
on applying the above properties , we get
ln( 2² × 3³ ) = ln(2²) + ln(3³) using property (1)
or
= 2ln(2) + 3ln(3) using property (2)
on substituting the values given in the question
we get
ln(108) = ( 2 × 0.69 ) + ( 2 × 1.10 )
= 1.38 + 2.20
= 3.58
Answer:
1 and 19
Step-by-step explanation:
Those factors are 1 and 19. They add up to 20.
Answer:
70 students
Step-by-step explanation:
As, 30% Mike surveyed
And these 30% are 21 students
So 30% of X = 21
= 30/100 x X = 21
= 30X = 2100
So X = 2100/30
X = 70
So 70 students were surveyed
For this case we have to:
Let "x" be the variable that represents the number of tomatoes in each box.
Let "y" be the variable that represents the weight of the empty box.
Then, the number of tomatoes in each box will be given by:
So, there are 48 tomatoes in each box
ANswer:
48 tomatoes
