Answer:
36 inches
Step-by-step explanation:
lets think of it as a ratio,
80:w
20:9
so we want 20 to get to 80
and 9 to get to w right?
so if we just move the smaller rectangle to the corner, then 20*4=80 right?
and if we do that, we do it to 9 as well, 9*4=36
w=36
Y = -5x + 1
x = 1 , y = -4
x = 2 , y = -9
x = 3 , y = -14
so the answers are
(1,-4)
(2,-9)
(3,-14)
Chris and Jim must replace a <em>total</em> quantity of 17 tyres.
<h3>What is the minimum number of tyres to be replaced?</h3>
In this problem we must use an inequality of the form f(x) ≥ a, where f(x) is the difference between the number of tyres replaced by Jim and the number of tyres replaced by Chris:
(25/20) · x - x ≥ 3
(5/20) · x ≥ 3
x ≥ 12
Then, the <em>minimum</em> number of tyres to be replaced is n = 15 + 12 = 17 tyres.

Answer:
The angle complies with the state regulations.
Step-by-step explanation:
The angle of elevation is the angle 
in the figure, and from trigonometry we find that
taking the inverse sine of both sides we get
which gives
which is less than 5°, and therefore is well within the state regulations.
