Answer:
a. the difference in lengths of the two pieces of carpet is 1.1m
b. total length of the carpet put together is 8.1m
Step-by-step explanation:
⇒ One piece of carpet is 3.5m long (given)
⇒ Another piece of carpet is 4.6m long (given)
a. What is the difference in lengths of the two pieces of carpet?
⇒ difference means subtract
⇒ 4.6m - 3.5m = 1.1m
b. Simon lays the two pieces of carpet together, end to end, What is the total length of the carpet?
⇒ total length means addition
⇒ 4.6m + 3.5m = 8.1m
The perpendicular line would have a slope of 1/3.
Perpendicular lines have opposite and reciprocal slopes. So first we have to find the slope of the original line. We can do this by solving the equation for y.
5x - 9y = 1
-9y = -5x + 1
y = 5/9x - 1/9
To do the opposite, take the original slope (5/9) and change the sign (-5/9).
To do the reciprocal, take the slope we changed (-5/9) and flip it as a fraction (-9/5).
This gives us a new slope of
Answer:
<h2><u><em>
x = 18 °</em></u></h2>
Step-by-step explanation:
you have a rotation angle of 360 °, take out the known values (360 ° -90 ° -144 ° = 126), 144 ° is part of a flat angle of 180 °, from 180 ° remove 144 and you have 36 °, they are opposite angles therefore the same. therefore 360 - 144 - 90 - 36 - 36 = 54.
54 is 3x, so x = 18 ° (54 : 3 = 18)
