Please Help! A group of tourists can be sorted into tour boats in groups of 4 or in groups of 6. In either case, there are no em

ozzi

Answer:

36 is the correct answer.

Step-by-step explanation:

It is given that there are a group of tourists that can be sorted in a group of either 4 or 6 so that there are no empty seats.

It means that the total number of seats should be a multiple of both 4 and 6.

For finding such a number we can simply find out LCM (Least Common Multiple) of 4 and 6.

LCM of two numbers p and q is the minimum number which can be completely divided by both the numbers p and q.

Let us find the LCM of 4 and 6 here, using the factors:

4 = 2 $\times$ 2

6 = 2 $\times$ 3

The common factor(shown as underlined) is used only once in the LCM.

So, LCM = 2 $\times$ 2 $\times$ 3 = 12

So, 12 is the minimum number which can be divided by 4 and 6 both.

But, we are given a condition that number of tourists are more than 25 and lesser than 45. So, the number of seats can be in between 25 and 45.

Now, let us see multiples of 12:

12, 24, 36, 48, 60, ......

The number that lies between 25 and 45 is 36.

So, the number of total seats can be 36.

Patricia baked some cupcakes for sale. she put half of the cupcakes equally into 6 big boxes and the other half equally into sma

mojhsa [17]

Answer:

The answer is given below

Step-by-step explanation:

Let us assume Patricia baked x number of cakes. She put half of the cupcakes (i.e x/2) equally into 6 big boxes.

6 big boxes contained $\frac{x}{2}$ cakes, therefore 1 big box would contain $\frac{x}{2}/6=\frac{x}{12}$ cakes.

Let us assume she put the other half into 14 small boxes, therefore each small box would contain $\frac{x}{2}/14=\frac{x}{28}$ cakes.

There were 45 cupcakes in 3 big boxes and 8 small boxes altogether. That is: $3(\frac{x}{12} )+8(\frac{x}{28})=45\\ 84x+96x=15120\\180x=15120\\x=84$

Therefore Patricia baked 84 cup cakes

She sold all the small boxes and collected $189, i.e she sold 14 small box for $189. Each small box = $189/14 = $13.5
