First convert them into improper fractions: $6\frac{1}{3} =\frac{19}{3}$ and $9\frac{1}{2} =\frac{19}{2}$ . Now we add: $\frac{19}{2}+\frac{19}{3}=\frac{95}{6}$ or $15\frac{5}{6}$ .

Musya8 [376]

Answer:

Following are the solution to this question:

Step-by-step explanation:

They provide various boxes or various objects. It also wants objects to be distributed into containers, so no container is empty. All we select k objects of r to keep no boxes empty, which (r C k) could be done. All such k artifacts can be placed in k containers, each of them in k! Forms. There will be remaining $(r-k)$ objects. All can be put in any of k boxes. Therefore, these $(r-k)$ objects could in the $k^{(r-k)}$ manner are organized. Consequently, both possible ways to do this are

$=\binom{r}{k} \times k! \times k^{r-k}\\\\=\frac{r! \times k^{r-k}}{(r-k)!}$

Consequently, the number of ways that r objects in k different boxes can be arranged to make no book empty is every possible one

$= \frac{r!k^{r-k}}{(r-k)!}$

The size of a playground is 160 feet by 360 feet. A model is created that measures 4 inches by 9 inches. Is it a rate, ratio onl

Vera_Pavlovna [14]

Answer:

The model is made in a<u> 1:40 ratio </u>

Step-by-step explanation:

How many times is 4 multiplied to be equal to 160?

4(x) = 160

X = 160 / 4

The proportion, rate, and ratio are almost the same.

They represent the correspondence between the parts and the whole since they all express a binary relationship between the quantities, that is, objects, people, tablespoons.

If the ratio is 1: 2 it could be read that for every 1 there are 2.

For example 1: 2 cups; For every cup of something there are 2 cups of something else.

In this case, 1:40; For every inch of the model, there are 40 feet in the playground.
