Answer:
s = 3x - (1/2)y
Step-by-step explanation:
The perimeter of a square is 4s, where s is the side length. Here,
12x - 2y = 4s, and so s = 3x - (1/2)y
Answer:
a = 8
Step-by-step explanation:
8 + 3 + 1 - 4 = 3a - 2a
8 = a
a = 8

Answer:
It takes Michael 1 hour, 14 minutes and 7 seconds to seal the driveway close
Step-by-step explanation:
Hi
Leon do the work in 17 hours that means the rate of his work is
, so he do
of the work in two hours, therefore Michael do the other
of the work, thus Michael rate will be
.
So it takes Michael
to complete the work, or ![\frac{4h}{17} \times \frac{60min}{1hour} =14\frac{2}{17} min\\\\\frac{2}{17} min \times \frac{60 secs}{1min}=7secs](https://tex.z-dn.net/?f=%5Cfrac%7B4h%7D%7B17%7D%20%5Ctimes%20%5Cfrac%7B60min%7D%7B1hour%7D%20%3D14%5Cfrac%7B2%7D%7B17%7D%20min%5C%5C%5C%5C%5Cfrac%7B2%7D%7B17%7D%20min%20%5Ctimes%20%5Cfrac%7B60%20secs%7D%7B1min%7D%3D7secs)
![1h \ 14 min \ 7secs](https://tex.z-dn.net/?f=1h%20%5C%2014%20min%20%5C%207secs)
Answer:
4/3
Step-by-step explanation:
The tangent of any angle (θ) in standard position that has point (x, y) on its terminal ray is ...
tan(θ) = y/x
__
For the given point on the terminal side, the tangent is ...
tan(θ) = (-4)/(-3) = 4/3
_____
<em>Additional comment</em>
There are several ways this can be explained. One of them makes use of the relation between rectangular and polar coordinates:
(x, y) = (r·cos(θ), r·sin(θ))
Then the ratio y/x is ...
y/x = (r·sin(θ))/(r·cos(θ)) = sin(θ)/cos(θ) = tan(θ)
