a drink bottler needs to fill 40 one pints bottles and he has two tanks one that contains 2 gallons of soda and a second that co
2 answers:
Answer:
Both tanks
Step-by-step explanation:
This is a unit conversion problem. We need to know how many gallons are there in 40 pints and with this information we will know in which tank he will need to fill in the bottles. In order to solve it we need the equivalence between this two measurement units. Which is:
This equivalence can be used as a conversion factor like this:
Applying it to the problem we can convert from pints to gallons:
He will need both tanks because neither of them has enough gallons to fill 40 one pint bottles.

Answer: 709
Step-by-step explanation:
The formulas we use to find the required sample size :-
1.
, where = population standard deviation,
E = Margin of error .
z* = Critical value
2. , where p= prior estimate of population proportion.
3. If prior estimate of population proportion is unavailable , then we take p= 0.5 and the formula becomes
Given : Margin of error : E= 3% =0.03
Critical value for 95% confidence interval = z*= 1.96
A study conducted several years ago revealed that the percent of junior executives leaving within three years was 21%.
i.e. p=0.21
Then by formula 2., the required sample size will be :
[Round to the next integer.]
Hence, the required sample size of junior executives should be studied = 709
So to find the answer to this, you have to consider that 
- half because half the pocket money (x) was spend on clothes, then plus 9 because that's how much extra she gained and 13 because that was the result of all the changes.
To solve this, first subtract 9 from both side, which leaves you with
and 
is the same as 
, so to solve this, multiply both sides of the equation by two, resulting in 
. SO from this we can conclude that the weekly allowance is $8
To solve this, first subtract 9 from both side, which leaves you with
To write the number is standard form we need to move the decimal point six times to the right, then:
therefore the answer is b.
