Answer:
245 tiles
Step-by-step explanation:
1 meter = 100 cm
Area of bathroom = 3.5m x 2.8m = 350x280 = 9800 cm²
Area of each tile = 20cm x 20cm = 400 cm²
Total number of tiles required = 9800/400 = 245
<u>Note</u>
Strictly speaking we have to find out how many tiles can be fitted in the length and breadth of the bathroom. Since the bathroom is 350 cm wide, we can fit 350/20cm = 17.5 tiles. However, there is no concept of 1/2 tile so the question has an ambiguity. along the width, we can fit 280/10 = 14 tiles
17.5 x 14 = 245 but if the question is reworded to how many tiles do we need to purchase to floor the bathroom it would be 18 x 14 = 252
here is the answer I just took a picture because I already answered this for someone eles

Step-by-step explanation:
Answer:
The response that are true are:
- linear function has a constant additive rate of change, while a nonlinear function does not.
Since in linear function the rate of change is always equal as for a linear function we get a equation of line such that the slope is same.
- On a graph, the function must be a straight line to be linear.
Liner means there is a straight line of the function.
( Also it need not be true that the independent variable increases by 1.
There may be change of some other quantity in independent variable )
