<em>Question:</em>
<em>If one basket contains five bottles each weighing 7 1/4 and the other basket has six apples each weighing 6 1/2 ounces. Which basket is heavier and by how much ?</em>
Answer:
The basket of bottles weighs more than the basket of apples by ounces
Step-by-step explanation:
Given
Required
Determine which basket is heavy
and by how much?
First, we need the total weight of each basket.
For the bottles' basket
For the bottles' basket
By comparing both total weights,
Hence:
The basket of bottles weighs more than the basket of apples
Calculating the difference:
Hence:
It weighs more by ounces
Given:
The piecewise function is
To find:
The range of given piecewise function.
Solution:
Range is the set of output values.
Both functions and
as linear functions.
Starting value of is at x=-4 and end value is at x=3.
Starting value:
End value:
Starting value of is at x=3 and end value is at x=6.
Starting value:
End value:
Least range value is 0 at x=-4 and 0 is included in the range because -4 is included in the domain.
Largest range value is 11 at x=6 and 11 is not included in the range because 6 is not included in the domain.
So, the range of the given piecewise function is [0,11).
Therefore, the correct option is A.
