Answer:
120 ft
Step-by-step explanation:
The distance the gravel covers is the total distance times the percentage that the gravel covers
We know the gravel covers 66 ft and the percentage is 55%
distance gravel = total distance * percentage
66 = total distance * 55%
66 = total distance *.55
Divide each side by .55
66/.55 = total distance *.55/.55
120 = total distance
Answer:
Option d is the correct answer
Step-by-step explanation:
The slope-intercept form of an equation for a line passing through given points can be represented as
y = mx + c
Where
Slope, m = (change in value of y on the vertical axis) / (change in value of x on the horizontal axis)
c = y-intercept
We want to find the slope-intercept form of an equation for the line that passes through (–1, 2) and is parallel to y = 2x – 3
For two lines to be parallel to each other, the slopes must be equal.
For y = 2x – 3
Slope,m = 2 (comparing with the slope intercept form stated above).
This means that the slope of the line
that passes through (–1, 2) is also 2
To find the y-intercept, c of this equation,
2 = 2 × - 1 + c
2 = -2 + c
c = 2+2 = 4
The equation is
y = 2x + 4
4x^2 + 5x - 8 + (- 4x^2 - 5x + 8) = 0
all ur doing is changing the signs so they will cancel each other out.
so ur adding : -4x^2 - 5x + 8
Answer:
9.5 minute
