Answer: 1) y=41 has the slope m = 0

2) A line which is perpendicular to y=41 is a vertical line, it's parallel to Y-axis. It has no slope or saying mathematically m is undefined.

3) A line which is parallel to y=41 has the same slope as y=41 or m=0

Answers: m=0, m undefined, m = 0

Keeping in mind the rules for significant figures, determine how many milliliters there are in 0.073 gallons. 1 gallon = 4 quarts, 1 liter = 1.057 quarts

we are given

there are in 0.073 gallons

we can see that there are two non-zero places after decimals

so, there are two siginificant figures

step-1: Change gallons to quarts

we know that

1 gallon = 4 quarts

so, we can write as

step-2: Change into liter

we know that

1 liter = 1.057 quarts

or

step-3: Change into millilitre

we know that

Since, it is asking for only two significant figures

so, we can also write as
