The managers of franks snack shack buys hamburgers in packages of 30 and hamburger buns in packages of 24. He cannot buy part of
Andreas93 [3]

Answer:

He has to buy 4 packages of hamburgers in packages of 30 and 5 packages of hamburgers in packages of 24

Step-by-step explanation:

First we have to calculate the least common multiple (LCM) of 24 and 30

We will calculate the LCM of 24 and 30 by prime factorization method

24 = 2*2*2*3 = 2^{3} * 3^{1}

30 = 2*3*5 = 2^{1} *3^{1}* 5^{1}

LCM = 2^{3}* 3^{1}*5^{1}

LCM = 120

So number of hamburger buns = 120

Therefore, he must buy 120/24 = 5 packages of hamburgers in packages of 24 and he must also buy 120/30 = 4 packages of hamburgers in packages of 30

Nour and Rana are shopping for a Christmas tree. They are deciding between 222 different types of trees (real and fake) and 444
ioda

From what the statement says the question seems to be to represent the sample space of randomly choosing a type of tree and a color for the decorations

In this case, what we must do is identify the events that exist and the options that each event has, like this:

Event 1:

Tree type: real or fake

Event 2:

Colors for the ornaments: White (W), Silver (S), Gold (G) or Purple (P)

Since in an event there are 2 options and the other 4 options, the final number of options would be 2 * 4, that is, 8 options, represented below:

(real, W), (real, S), (real, G), (real, P), (fake, W), (fake, S), (fake, G), (fake, P)

The above would be the sample space of the events.

Now the probability of 1 coming out is 1 over the event total, or 1/8.
