Answer:

The cat should receive 1/5 of the can of food at each meal.

Step-by-step explanation:

Given that a cat is to receive 90 kcal of a canned food at each meal, and the food has a caloric density of 450 kcal per can, to determine what fraction of a can it should receive at each meal, the following calculation must be performed:

1 / (450/90) = X

1/5 = X

Thus, the cat should receive 1/5 of the can of food at each meal.

mote1985 [20]

The number of passengers that :

Needs Transfer only = 13 passengers
Are going to work only = 17 passengers

Let :

Passengers that needs transfer = T = 35

Passengers going to work, W = 39

Passengers who do not need transfers and aren't going to work = 12

Using a venn diagram :

Let the Passengers who do not need transfers and are going to work and needs transfer = x

Passengers who need transfer only = 35 - x

Passengers who are going to work only = 39 - x

To find x :

35 - x + 39 - x + x + 12 = 64

86 - x = 64

-x = 64 - 86

-x = - 22

x = 22

the number of passengers that need transfers but aren’t going to work will be = 35 - 22 = 13 passengers

the number of passengers that are going to work but do not need transfers will be : 39 - 22 = 17 passengers

What is the sum of the series 1 + ln3 + (ln3)^2/2!?

tresset_1 [31]

$\displaystyle\sum_{n\ge0}\frac{(\ln3)^n}{n!}=e^{\ln3}=3$

which follows from the power series representation for $e^x$ ,

$e^x=\displaystyle\sum_{n\ge0}\frac{x^n}{n!}$

and taking $x=\ln3$ .
