Two old RSM students were standing ten feet apart when they ran in opposite directions with speeds of 180 feet per minute and 16
inessss [21]

The number of minutes that would pass before they were 1870 feet apart is 5.47 minutes

  • Since one student runs at a speed of 180 feet per minutes, in time t minutes, he moves a distance of d = 180t.
  • Also, the second student runs at a speed of 160 feet per minute, in time t minutes, he moves a distance of d' = 160t.

Since they are initially 10 feet apart, their total distance apart after t minutes is D = d + 10 + d'

D = 180t + 10 + 160t

D = 340t + 10

<h3>Number of minutes before they are 1870 feet</h3>

Making t subject of the formula, we have

t = (D - 10)/340

Since they are 1870 feet apart after t minutes, D = 1870 feet.

t = (D - 10)/340

t = (1870 - 10)/340

t = 1860/340

t = 5.47 minutes

So, the number of minutes that would pass before they were 1870 feet apart is 5.47 minutes

write an equation in slope intercept form for the line that is perpendicular to y=-1/4x+2 and passes through the points (-4,3)
PilotLPTM [1.2K]
For lines to be perpendicular their slopes must be negative reciprocals of one another, mathematically:

m1*m2=-1, and in this case:

-m/4=-1

-m=-4

m=4, so the slope of the perpendicular line is 4 so we have thus far:

y=4x+b, using point (-4,3) we can solve for the y-intercept, "b"

3=4(-4)+b

3=-16+b

19=b, so our line is:

y=4x+19

7.) The width of a vegetable garden is times its length. If the length of the garden is 73
Solnce55 [7]

Answer:

So, the length (L) = 7 3/4 ft = 31/4 (as an improper fraction)

 

the width (W)  = (1/3)xL

 

So the width = 1/3 x (31/4) =

31/12 = 2  7/12 feet

Step-by-step explanation:
