What is the distance between parallel lines y=x+3 and y=x+1, rounded to the nearest hundredth?

Answer:

The distance is 1.41 to nearest hundredth.

Step-by-step explanation:

The line y = x + 3 passes through the point (0, 3) on the yaxis.

Find the perpendicular line passing through this point:

y  - 3 = -1(x + 0)

y = -x + 3

Now find the point where this line intersects the line y = x + 1:

y = -x + 3

y = x + 1

-x + 3 = x  + 1

3 -1 = x + x

2x = 2

x = 1

and y = 2

So this point is (1, 2)

We require the distance between this point and (0, 3)

This = √((3-2)^2 + (0-1)^2) = √2

= 1.4142

at franklin middle school,3/8 of the students take a bus to school, 3/5 walk, and the rest bike. There are 20 students who bike
nordsb [41]

Answer:

There are 800 kids in the school.

Step-by-step explanation:

Let x be the answer (how many kids are in the school).

Let's add them together. 3/5+3/8 = how many people do not bike to school, which is 0.975 of everyone. 1-0.975 = 0.025, which means 0.025x = 20. 0.025x = 1/40, so 1/40x = 20. Multiplying, we have x =800.
