Answer:

30 minutes

Step-by-step explanation:

The hiker starts at sea level or 0 feet. He descends 25 feet every minute. This can be written in an equation as so, 0 acting as the starting point, f being feet, and m being minutes:

f = 0 - 25m

This simplifies to:

f = - 25m

We can substitute f in for -750

-750 = - 25m

Now, we divide by - 25 by both sides of the equation

-750 ÷ - 25 = 750 ÷ 25 = 30

30 = m

It would take 30 minutes for the hiker to get to - 750 feet in elevation.

I Hope That This Helps! :)

PLEAASE HELP
gladu [14]
Well you are given the equation so let's plug in for kaylib and see how many miles she can see
distance = sqrt [(3 * height) / 2]
d = sqrt [(3 *48) / 2]
d = sqrt (144 / 2)
d = sqrt (72)
d = sqrt (3 * 3 * 2 * 2 * 2)
d = 6 * sqrt (2)

You you did not list Addisons height but I will say she is at x feet above sea level. we plug in x for height:
d = sqrt [(3x) / 2]

It it says how much farther for Addison which means she can see farther. to find difference we just subtract kaylibs distance from Addison. so:
sqrt [(3x) / 2] - 6 * sqrt (2)

plug in your x and use a calculator to get a decimal approximation

What is the slope of a line perpendicular to the line whose equation is<br> 2x – 2y = 20.
Simora [160]

Answer:

-1

Step-by-step explanation:

Solve for y into y=mx+b

2x-2y=20

-2y=-2x+20

y=(-2x+20)/-2

y=x-10

the slope is m, so it’s 1

A line perpendicular to that would be -1
