**Chemistry**

Technically this problem can't be worked without know the density of the solution or the final volume. We will assume that the final volume is 1L. moles HCl = grams HCl/molar mass HCl. Then M HCl = moles/L soln Finally, pH = -log(H^+)

**Algebra**

Before the final exam, a student has test scores of 72, 80, 65, 78, and 60. If the final exam counts as one-third of the final grade, what score must the student recieve in order to have a final average of 76 percent? Thanks!!

You shouldn't have any trouble. Final molarity = final moles/final liters of solution. Post your work or detailed questions if you get stuck.

No, Problem! Thank you so much for the answer!

What is a coterminal angle with 170 degrees?

I cannot decipher your problem. Where do p, q, and r come from? what is ff and FI ?

**Trig**

this is just like the carousel problem. w = 2pi*f s = w*r

**Algebra**

In order to solve this problem, you would have to distribute the negative (- sign) to the (x-2), making the problem x+2-x+2. The two x's would cancel out, therefore making the final answer 4.

**Algebra 2**

The problem is 3x^2 - 26 + 35 (We have to factor it!) So, I did the problem, but I'm not sure how to write the final answer. This is what my problem looks like so far: 3x^2 - 26 + 35 (3x^2-21x)-(5x+35) 3x(x-7)-5(x+7) and this is where I have the problem. I know I need to put (...

**Physics**

I believe you stated the problem incorrectly. It does not accelerate FROM 96.56 km/h. That is the FINAL velocity after 4.3 seconds. It accelerates TO 96.56 km/h The average speed during acceleration at a constant rate (from a standing start) is half the final velocity.

**trig-reply to Reiny**

Since we did not resolve your question, I am curious where you got this problem. Is it from a textbook? Is in an assignment problem? Just curious, since it obviously not a true statement.

**trig**

If a triangle has an area of 50 square units and has angles that measure 15, 65, and 100 degress, find the length of the shortest side to the nearest tenth. Do not round till the final answer.
