algol [13]

Answer:

166\frac{2}{3}\ m

Step-by-step explanation:

Let

x ----> the average depth of the resulting layers of ash and rock

we know that

To find out the average depth, divide the cubic kilometers of molten rock by the area where all the ejected material fell.

so

\frac{100\ km^3}{600\ km^2}=\frac{1}{6}\ km

Convert to meters

Remember that

1\ km=1,000\ m

so

\frac{1}{6}\ km=\frac{1}{6}(1,000)=\frac{1,000}{6}=\frac{500}{3}\ m

Convert to mixed number

\frac{500}{3}\ m=\frac{498}{3}+\frac{2}{3}=166\frac{2}{3}\ m

50 POINTS AND BRAINIEST PLEASE HELP
exis [7]

Answer:

<h2><u>y = -2x</u></h2>

Step-by-step explanation:

If you notice very carefully then you will see that the line passes through the points :

( 1 , - 2 )

( - 1 , 2 )

Hence the value of x = 1 when the value of y = - 2 .

We know that - 2 × 1 = - 2

⇒ - 2 x = y

⇒ y = - 2x

Hence the first OPTION is correct .

Verification :

For points ( - 1 , 2 ) we can write :

y = - 2x

⇒ 2 = - 2 × - 1

⇒ 2 = 2

Hence the answer is verified .

Always try to use the converse of the graphical method .

( Nothing converse is there ... just saying the opposite steps of that method :P )

I mean in graphical method we plot points and then join , here identify the joined points and then make the equation .
