P greater than or equal to -4
Answer:
$659.25
Step-by-step explanation:
Since its 25 percent off we need to see what it would look as a decimal
1-.25=.75
879times.75= 659.25
Let
x--------> the border’s length
y--------> the border’s width
P--------> perimeter of the border
we know that
x=5+y------> equation 1
P=2*[x+y]-----> P=2x+2y
P <=180 ft
(2x+2y) <= 180-------> equation 2
substitute the equation 1 in equation 2
2*[5+y]+2y <= 180
10+2y+2y <= 180
4y <= 180-10
4y <=170
y <=42.5 ft
so
the maximum value of the width is 42.5 ft
for y=42.5 ft
x=42.5+5------> x=47.5 ft
the answer is
the width of the border is less than or equal to 42.5 ft
Answer:
The slope will be:
slope = 0.3
Step-by-step explanation:
As we know that the slope of a certain line is basically the measure of its steepness.
Mathematically, the slope can be calculated as 'rise over run'.
In other words, the 'rise' is 'change in y', and 'run' is 'change in x'.
Given
The roof of the school has a rise = 3.6 meters = rise = change in y
The roof of the school has a run = 12 meters = run = change in x
So the slope will be:
slope = rise ÷ run
= 3.6 ÷ 12
= 0.3 ∵( 3.6 ÷ 12 = 0.3)
Therefore, the slope will be:
slope = 0.3
