Find the distance between the parallel lines m and n whose equations are
MA_775_DIABLO [31]

Answer:Find the distance between the parallel lines m and n whose equations are y = x + 4 and y = x - 6, respectively.

There are several ways to do this...here's one

Let (0, 4) be a point on the first line

Then.......a line with a negative reciprocal slope going through this point will have the equation :

y = -x + 4........so......we can find the intersection of this line with y = x - 6....set both equations equal

-x + 4  = x - 6   add x, 6 to both sides

10 = 2x     divide both sides by 2

5  = x

So...using -x + 4, the y value  at intersection  = -1.......

So...we just need to find the distance from  (0,4)  to ( 5, -1)  =

√[ (5)^2 + (4 + 1)^2 ] =  5√2  ≈  7.07 units

Here's a pic....AB is the distance  with A = (0,4)  and B = (5, -1)

FromTheMoon [43]

Answer

8(40-y) + 6y =300

320 - 8y + 6y =300

-2y=-20

y=10

This leaves x to be 30.

You should spend 30 minutes on machine 1 and 10 minutes on machine 2.

a hamster wheel has a 7 inch diameter. How many feet will a hamster travel in 100 revolutions of the wheel?
Firdavs [7]
1 revolution = circumference of the wheel = pi * diameter

= 3.14 * 7 inch

so 100 revolution = 100 * 3.14 * 7 = 2198 inches

= 2198 / 12 = 183.17 feet
