Answer:

she will need to fill pour the water 3 1/2 times.

Step-by-step explanation:

in easiest terms subtract 1/2 cups of water until you cant take 1/2 cups out. then you see how much more you need to take out then do the math. in this case you need to take out 1/4 cups more out until you have nothing left. if you can visualize this in your head you know that 1/4 is 1/2 of 1/2 so you take out half as much as you did before.

frosja888 [35]
You’re gonna have to use the quadratic formula here and a bit of thinking. We know y is height, and once it touches the ground, it will be 0.

(-b +- sqrt b^2 - 4ac)/2a
2 +- sqrt(4 + 48(400))/-32
(2 +- 138.58)/-32
We don’t want a negative time because it’ll make no sense. So do subtraction

(2-138.58)/-32 = 4.27 seconds aka 4.3 seconds

Solve for x, x^2-3x-5=0
Sophie [7]

Okay so for this one, we have to isolate our X.Lets start by moving the negative 5 on the other side of the equal sign. Remember to not mix a number that is with an X with a normal number (in this case it would be the -3x and the -5). So in putting our -5 on the other sign it becomes positive. Here’s what we have: x^2-3x=5. x^2 is the same thing as 2x.So now you have to minus 3x off of your 2x. This gives us -1x, but can just be put as -x. So now we have -x=5. You’re answer could either be 5 or -5 if you decided to divide it by -1 seeing as your -x is technically -1.
