Answer: Option A
Step-by-step explanation:
If we have 5 cans of ketchup they cost $ 5.25. Then the unit price of cans is what each can costs individually.
The unit price should then be less than $ 5.25, and that is the price for 5 cans and we want to know the price for just one can of ketchup.
Then to calculate the price of each can divide the price of the 5 cans by 5.
Note that both the numerator and denominator approach 0 as
, so we can try using L'Hopital's rule.
The denominator is nonzero at
, so the limit is equivalent to
Let x be the smallest odd number.
x+(x+2)+(x+4)=147
3x+6=147
x=47
therefore the smallest odd no. is 47.
Answer:
2.49556
Step-by-step explanation:
The rate Ritz can eat apples is 8/15 apples per minute.
Set the rate (which is measured apples / minutes) equal to 16 apples / t minutes.
(8/15) = (16/t)
Cross multiply.
16*15 = 8t
t = 20
The answer is 30 minutes. You could solve the problem with basic reasoning as well. 16 is twice the number of apples as 8, so the time it takes to eat them will be double 15 minutes.
