Answer:
0.5r
Step-by-step explanation:
If Jerry completed his journey in half the duration that Macy did, it implies Macy's time was twice as lengthy. Assuming Jerry’s speed is r, Macy’s speed would therefore be 0.5r, indicating she travels at half Jerry's pace and takes twice as long to cover the distance.
Answer:
The three errors are:
1) Incorrectly swapping the variables x and y.
2) Failure to use the ± symbol.
3) The domain is wrong; it should be x ≤ 0.
Step-by-step explanation:
Review the following steps.

Step 1: 
The initial step is incorrect because the variables x and y were switched improperly; it should be:

Step 2: 
Step 3: 
Step 4:
, for x ≥ 0
Step 4 contains an error as the ± sign is required. Additionally, the function's domain is inaccurately stated.
The radicand must be nonnegative, implying that x must satisfy x ≤ 0.
Response:
6.48
Detailed explanation:
The calculation required to determine the number of tiles for the border is presented below:-

Here,
The length measures 2.02 m
And the width is 1.22
Substituting these dimensions into the formula provided above
Consequently, the total number of tiles necessary to create the border is


= 6.48
Hence, to find the tiles required for the border, we utilized the aforementioned formula.
The result is 0.81 because you must multiply 0.60 by 1.35 to get 0.81. Then divide 0.81 by 0.60.
