For choice A, we can rearrange the equation to 38x=0, so it has exactly one solution, x=0.

For choice B, we rearrange the equation to 38x=36, so this too has exactly one solution, x=\frac{36}{38}=\frac{18}{19}.

Rearranging the equation in choice C by eliminating the x terms gives us the false equality -18=18, so this equation has no solutions.

Eliminating x in the equation in choice D gives the equality 18=18, which is always true, so this equation has infinitely many solutions.

Thus, we conclude that choices A and B work.

The second solid is a parallelepiped.

The volume of a parallelepiped is the area of the base times the height (the perpendicular distance from the base to the top face).

Given that the second solid has the same base of the cube and the same height, then the volumes of two solids are the same.

Answer: 1000 cubic feet.

D = 1/2 a t^2 is given. And it wants you to find t in terms if a and d. Which means, you need to arrange the equation and let t be alone.

If you let t^2 alone ;

2d/a = t^2

And square root t^2 will give you t ;
SquareRoot(2d/a) = t

The answer is (2)

Find a coterminous angle between 0 and 2 pi for each given angle. 191pi/45
Sedaia [141]

Check the picture below.

let's recall that 2π is a full go-around or namely a revolution

\bf \cfrac{191}{45}\implies \cfrac{45+45+45+45+11}{45}\implies \cfrac{45}{45}+\cfrac{45}{45}+\cfrac{45}{45}+\cfrac{45}{45}+\cfrac{11}{45} \\\\\\ 1+1+1+1+\cfrac{11}{45}\implies \stackrel{\textit{and this more}}{\underset{\textit{2 go-around}}{\underset{\uparrow }{2+2}+\stackrel{\downarrow }{\cfrac{11}{45}}}}
