$1.35 x 10 = $13.50 for 10 gallons
$23.50 - $13.50 = $10.00
$1.35 x 7 = $9.45 for 7 more gallons
17 gallons is $22.45
17/27 = 459 miles but I'm missing the last bit of change so round it up to 460 for a total of miles
Let the length of the northern side be x and length of the west sides be y. The cost of fence is:
C=10x+10y+5y
and the area enclosed be A=xy
10x+15y=4000
x=400-1.5y
A=400y-1.5y^2
A is maximized when y=400/3 and x=200
Answer:
I'm pretty sure its a bridge, hopefully that's right <3
Step-by-step explanation:
Answer:
The equation of line passing through points (1 , 0) is x - 5 y - 1 = 0
Step-by-step explanation:
Given equation of line as
x + 5 y = 30
Now, equation of line in standard form is y = m x + c
where m is the slope
So, x + 5 y = 30
Or, 5 y = - x + 30
Or, y = -
x + 6
So, Slope of this line m = - 
Again , let the slope of other line passing through point (1 , 0) is M
And Both lines are perpendicular , So , products of line = - 1
i.e m × M = - 1
Or, M = -
Or, M = - 1 × -
= 
So, equation of line with slope M and points (1, 0) is
y -
= M × (x -
)
Or, y - ( 0 ) =
× ( x - 1 )
Or, y =
x -
× 1
Or, y =
x - 
or, y +
=
x
Or, 5×y + 1 = x
∴ 5 y + 1 = x
I.e x - 5 y - 1 = 0
Hence The equation of line passing through points (1 , 0) is x - 5 y - 1 = 0 Answer
