Can anyone help please I don’t understand how to do it 2) A builder is tiling a new bathroom and requires 30 tiles which are of
length z and height y. Find an equation that would show the area of the tiled
parts of the bathroom in terms of x and y.

A= 30zy

Step-by-step explanation:

Let the area of the tiled parts of the bathroom be A.

A= area of 30 tiles

A= 30( length × height of tiles)

A= 30(z)(y)

A= 30zy

10 you would take 50/ .2

step-by-step explanation:

part a

x     y

0     8

1     7.5

2     7

3     6.5

4     6

5     5.5  

for every hour i deducted .5 inches from the length of the candle

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value

x       y

0       8

1       7.6

2       7.2

3       6.8
