Answer:
8,-1,-9,-18,-27,-36
and so on i would think it would be -27
Step-by-step explanation:
1/2 probability because 30 is half of 60.
Area of a triangle is 1/2 x base x height:
Area = 1/2 x 8 x 20.5 = 82 square cm.
It is hone-half the area of a rectangle with dimensions 20.5 by 8 cm.
Answer:
16
Step-by-step explanation:
To solve this equation, we need the formula for perfect squares:
or
<em>this is the formula we will use because the signs match the one in the question</em>.
Knowing these, we can set up an equation that assumes that the answer we will end up with is a perfect square.
Work:

- this is the setup for being able to solve for the unknown
, now we need to solve for
.
(I replaced
with
because I'm setting up this question to be a perfect square).

- multiply the left side. Remember that your answer will not be
, but
.

- Divide like terms and isolate the variable. In this case,
and
are on both sides, so dive them and they will be canceled out.

- divide by
and you will have your value for
.

- Now we plug
into our original equation equation for perfect squares.

Our final answer is 16.
<span>t=(512/216)^(1/2)
t=((8)(3)^(1/2))/9
t is about 1.539600718 hours
I don't believe the storm will be twice as long because the number multiplied by itself three times will give a much, much higher number than what was your original diameter.</span>
