She made $8,250 this week. 3% of 250,000 is $7,500, you add her weekly pay of $750 and it gives you your answer.
The volume of the triangular prism = 
Thus the volume is 
.
Thus the volume is 42 cubic km.
Hope that helps!
18/24 can both be divided by 6, so it's 3/4
Straight
Never ending (You can tell this as there are arrows on the ends)
On a diagonal with a negative slope
The answer is v=5x^2-100x+500. First, since we are finding the volume of a square you already know that the equation for a square is volume= length*width*height. Because 5 inches was cut off from each side, that means that each side is now 10 inches shorter than it originally was. So, then you substitute the values into the formula. So the length is x-10 and the width is also x-10 and the height is 5in. Then you write the formula like this (x-10)(x-10)5. Second, you substitute the values into the formula. Since there are 2 x's that would make x^2 and add that to 5 that would make 5x^2. Then you multiply -10*10=-100. Finally, you multiply -10*-10-5=500. Then you add them all together to get 5x^2-100x+500
