1250 lbs of sand.

So first let's find the volume of the sand in the sandbox. You have a square sandbox, with a side length of 5, meaning you have a length and width of 5. You also have half a foot of sand in the sandbox, meaning that you have a height of 0.5. To find the volume of the sand, multiply the length by the width by the height:

5 * 5 * .5 = 12.5

So you have 12.5 cubic feet of sand. If each cubic foot of sand is 100 lbs, then you just multiply the two:

12.5 * 100 = 1250.0

Simplify -8y^3(7y^2-4y-1) PLEASE HELP
max2010maxim [7]

Hey!



Alright, according to P.E.M.D.A.S., the first step to solving this expression is to distribute.


<em>Original Expression :</em>

\displaystyle\ -8y^{3} (7y^{2} -4y-1)


<em>New Expression {Distributed Old Expression} :</em>

\displaystyle\ -(56y^{5} -32y^{4} -8y^{3} )


Now all you have to do is simplify the parenthesis.


<em>Old Expression :</em>

\displaystyle\ -(56y^{5} -32y^{4} -8y^{3} )


<em>New Expression {Simplified} :</em>

\displaystyle\ -56y^{5} + 32y^{4} + 8y^{3}


<em>So, since the expression can no longer be simplified, the final answer is...</em>


<h3>\displaystyle\ -56y^{5} + 32y^{4} + 8y^{3}</h3>

Hope this helps!

There would be three equation associated with this problem. 

The first equation can be found by taking the x and y's from A and B 
First Equation: 2 - 3 / 1 - (-1)
Answer: -.5

The second equation can be found by taking the x and y's from B and C
Second Equation: -1 - 2 / -3 - 1
Answer: 12

The third equation can be found by taking the x and y's from C and A
Third Equation:  3 - (-1) / -1 - (-3)
Answer: 2

These are not equal measurements so, it isn't  right angle.
