Answer:
The cost of per kilogram of salami is = $9.1
Step-by-step explanation:
Given:
Hailey paid $13 for
kg of sliced salami.
To find cost per kilogram of salami.
Solution:
We will apply unitary method to find per kilogram cost of salami.
If
kg of salami costs = $13
Then 1 kg of salami will cost in dollars will be = ![13\div 1\frac{3}{7}](https://tex.z-dn.net/?f=13%5Cdiv%201%5Cfrac%7B3%7D%7B7%7D)
In order to divide by mixed numbers, we will convert mixed numbers to fractions.
⇒ ![13\div \frac{(7\times1)+3}{7}](https://tex.z-dn.net/?f=13%5Cdiv%20%5Cfrac%7B%287%5Ctimes1%29%2B3%7D%7B7%7D)
⇒ ![13\div \frac{10}{7}](https://tex.z-dn.net/?f=13%5Cdiv%20%5Cfrac%7B10%7D%7B7%7D)
In order to divide by fractions we will take reciprocal of divisor and then multiply.
⇒ ![13\times \frac{7}{10}](https://tex.z-dn.net/?f=13%5Ctimes%20%5Cfrac%7B7%7D%7B10%7D)
⇒ ![\frac{13\times7}{10}](https://tex.z-dn.net/?f=%5Cfrac%7B13%5Ctimes7%7D%7B10%7D)
⇒ ![\frac{91}{10}](https://tex.z-dn.net/?f=%5Cfrac%7B91%7D%7B10%7D)
⇒ ![9.1](https://tex.z-dn.net/?f=9.1)
Thus, cost of per kilogram of salami is = $9.1
Answer:
The statement is true that a function is a relation in which each y value has ONLY 1 x value.
Step-by-step explanation:
The statement is true that a function is a relation in which each y value has ONLY 1 x value.
The reason is very clear that we can not have the repeated x-values (two same x-values).
For example, given the set of the ordered pairs of a relation
{(3, a), (6, b), (6, c)}
As the same x values (x=6) has two different Y values. Hence, the stated relation is not a function.
In order to be a function, a relation must have only 1 x-value for each y-value.
Therefore, the statement is true that a function is a relation in which each y value has ONLY 1 x value.
