Answer:
Each of them need to pay to buy a whole pie together = $1.50
Step-by-step explanation:
Unit rates defined as the rates are expressed as a quantity of 1, such as 7 feet per second or 9 miles per hour, they are called unit rates.
As per the statement: You sell pies at a farmers' market for $7.50 each.
⇒ Cost of each pie = $7.50
Also, five people want to share a pie by splitting the cost equally.
Number of people = 5
then, by definition of unit rate;
unit rate per people =
Therefore, $1.50 will each of them need to pay to buy a whole pie together.
Answer:
$4 is spent on a big pail and $2 is spent on a small pail.
Step-by-step explanation:
Given:
10$ is spent on 2 big pails and 1 small one.
A small pail cost half as much as each big one.
Now, to find the amount spent on a big pail and on a small pail.
Let the cost of a big pail be
And the cost of small pail be
As given, there are 2 big pails.
And the total money spent = $10.
According to question:
Multiplying both sides by 2 we get:
Dividing both sides by 5 we get:
The cost of a big pail = $4.
So, the cost of a small pail =
Therefore, $4 is spent on a big pail and $2 is spent on a small pail.
By the definition of inverse function,the point (a,b) lies on the graph So, (b,a) must be lies on the graph of
.
Given:
Point (a,b) lies on the graph y= f(x).
Find:
The graph of must contain that point.
As per the definition of inverse function, if two one-to-one functions f(x) and g(x). If (f∘g)(x)=x and (g∘f)(x)=x. Then, we say that f(x) and g(x) are inverses of each other.
Then, its inverse is defined as
Therefore, we have to interchange x and y-coordinate of the points which lies on the function f to get f⁻¹.
Thus, the point (a,b) lies on the graph So, (b,a) must be lies on the graph of
.

Given:
Point (a,b) lies on the graph .
To find:
The point which is must be lies on the graph of .
Solution:
According to the definition of an inverse function, if a function is defined as
then, its inverse is defined as
It means, we have to interchange x and y-coordinate of the points which lies on the function f to get f⁻¹.
We have a point (a,b) lies on the graph . So, (b,a) must be lies on the graph of
.
Therefore, the correct option is (1).
