Ok; Since we know that in 45 min, she can walk 3 miles, we can divide it to see how many minutes it takes for her to walk 1 mile. 45 divided by 3 is 15. Which means it takes her 15 minutes to walk 1 mile. If we look back at the beginning, it says she takes 15 minutes. Now that we know that it takes her 15 minutes to walk 1 mile, the answer is that it takes her 1 mile to walk to the library.
Answer:
£2628.80 (might not be correct, but here me out \o/)
Step-by-step explanation:
16 and overs : 18.60
under 16 : 12.80
155 people and 49 are under 16 right
155 - 49 is 106, this is the amount of 16 and overs bought a ticket
then u do 318.60 x 106 = £1971.60
and £12.80 x 49 = £657.20
then add £657.20 + £1971.60 and u get £2628.80
p.s: again im not 100% sure if its correct :)
It would havs to be four times two minus three.
If two lines have the same slope, they are parallel.
If the product of 2 slopes is -1, the lines are perpendicular.
10. The lines do not have the same slope, so they are not parallel.
3 * (-1) = -3. The product is not -1, so the lines are not perpendicular.
Answer: neither
11. 2/3 and -3/2 are not equal, so the lines are not parallel.
2/3 * (-3/2) = -6/6 = -1
The product of the slopes is -1, so the lines are perpendicular.
Answer: perpendicular
12.
Plot the points (2, 16) and (5, 40).
Draw a line though them.
Then you can use the slope formula to find the slope.
m = (y2 - y1)/(x2 - x1) = (40 - 16)/(5 - 2) = 24/3 = 8
