Answer:

The difference is 48 meters

Step-by-step explanation:

<u><em>The question is</em></u>

What is the difference of the hikers' altitudes?

Let

x -----> the Melissa's altitude in meters

y ----> Brian's altitude in meters

we have that

x=+27\ ft ---> is positive because is above sea level

y=-21\ ft ---> is negative because is below sea level

Remember that the sea level is the altitude equal to zero

<em>Find the difference</em>

To find out the difference of the hikers' altitudes, subtract Brian's altitude from Melissa's altitude

so

27-(-21)

Remember that (-1)(-1)=+1

27+21=48\ m

Find the slope of a line perpendicular to <br><br> Y= -x -1
ad-work [718]
<h2>Greetings!</h2>

Answer:

The slope is 1.

Step-by-step explanation:

First, we must find the slope of the current equation.

This is the number in front of the x.

Seeing as this is -x, or -1x, the slope of this line is -1

When finding the slope of a line perpendicular, you need to find the \frac{-1}{slope}

So, in this case it is:

\frac{-1}{-1}

The minuses cancel out, leaving with 1 over 1 or 1/

So the slope of the line perpendicular is 1!

Bethan ____________ 7.2659

Clarry ______________8.159

Deena _____________ 7.4559

Ethan ______________ 8.9459

Freya ______________ 7.0159

Write the name of the stick insect with m > 8.85g

Mass (m) greater than 8.55 g

From the table :

8.945 > 8.55 ;

Hence, Ethan

(b) Write the name of the stick insect with m s 7.155 g
