OMG, Thank you so much! I really appreciate the help!

Thank you so much geust! This helps a lot, thank you so much!

We can immediately cancel out all numbers between 30 - 0 inclusive. 

So that leaves us with 75 + 72 + 69 + 66... + 36 + 33

The remaining is simple. We realize that 33 + 75 = 108 and 36 + 72 = 108. This pattern continues. 

There are 14 numbers bewteen 75 and 33, so we have 7 groups of 108. 

7 x 108 = 756

756

Hope this helps!

Hey @waterlili, 

For this problem, we see a answer of polynomials. The "degree" of a polynomial is the highest power in the polynomial. 

For example, \(2x^5 + 3x^3 - 2x + 1\)

The degree of this polynomial is 5. 

In your case, if the degree does not match, it doesn't matter what happens. 4 is going to always be the degree. 

So 4 is the answer. 

4

I remember seeing this problem in Alcumus, or maybe a similar variation of it. However, the solution is pretty simple. 

set y = 0, since we are trying to find out when the ball hits the ground, and when that happens, Y = 0. 

This looks like a quadratic formula! 

\(0 = -16t^2 + 26t + 105\)

Then, simply solve for this quadratic. There will be two answers, but one of them is negative, so choose the postitve answer.

\(\frac{-26 +\sqrt{26^2 - 4(-16)(105)} }{2(-16)}\) 

That should be the postive answer. Sorry, it's a little messy. Solve this equation and the answer shall be the final answer!

Hope this helps!

Hey Geust, I think none of the answers are correct. 

If Weslet earns $6.50 an hour at the Bames and Noble bookstore, then the money he earns will be depending on X. 

X is the number of hours he worked, and Y is the number of money he earned. 

We then see the equation unfold. $6.50 an hour for X hours is Y. 

We transfer this word phrase into an equation to get

$6.50x = y

Please tell me if I am incorrect. I hope this helps!

What is the less than or equal to \(\sqrt[3]{504}\)

\(\sqrt[3]{504} = 7.95811441579\)

The greatest integer less than  7.95811441579 is 7, so the answer is 7. 

7

\(R = 2s - 6t + 5/2\)

We subtract both sides by 5/2 to get

\(R - 5/2 = 2s - 6t\)

We add \(6t\)

to both sides and get

\(R - 5/2 + 6t = 2s\)

Dividing both sides by gets you

\(\frac{R + 6t - 5/2}{2} = s\)

Hope this helps!

Is it 10 x 10 x 10 = 1000?

Since there are 10 flavors to choose from and you can choose the same, then you always have 10 flavors to choose from right?
