Yes, ok I have done that, I drew a diagram, but the thing is, you have all these angles, the co interior angles, and I am unsure of which ones to use - you have the 30 from the NE and then there is 17 from SE but there is another one, and I am not sure ho...

Sorry, got caught in the moment. I think Reiny is right.

The two and the three are both being multiplied to the square roots that are on both sides of the equal sign. I don't know how to isolate the radicals(to get everything being added, subtracted, multiplied, or divided away) in order to square everything to...

How are you getting the five? I am not really understanding. Since the numbers 2 and 3 are being MULTIPLIED, how can you just add them instead of dividing

WHERE ARE YOU GETTING THE 5 AND THE 25. HOW ARE YOU MULTIPLYING THESE RANDOM NUMBERS TOGETHER?

my teacher told me that the only way you can square EVERYTHING was if you ISOLATE the radicals. What you're doing is something completely different. You could have told me you made up a completely different problem.

So you distribute the 3 and the 2 to the numbers inside the radical?

Thanks for your help, you spent a lot of time with my problem. It is GREATLY APPRECIATED and it helps with the confusion I had on the quiz today. My teacher was not there to answer my question and she had never taught us how to solve these type of problem...

Where did you get the 2 from in the second part of your solution?

THANKS WE HAVEN'T DONE THOSE PROBLEMS ALL YEAR!

I want to say that the speed is the steepness, but I took that class a while ago so I would double check my answer.

You want to subtract the price change and divide it by the original number. It would be set up as amount of change/original amount. Hope that helps.

I want to say that it depends upon the speed/rate that an object is traveling but I no longer have the book to double check myself.

since you can't find the square of 8 you look inside that number to see what other numbers can be squared. For instance, 8 is divisible by 2 and 4. You can find the square root of 4. That is the first step. Now on n^3 you simply put it in terms that are d...

It means quickly or swiftly

thanks so much. I really appreciate it.

What I'd advise is to balance the equation. What you do on one side of the equal sign, do it on the other. 9/2m-8= -5.5 + 4m 9/2m = 4 1/2m 4 1/2m -8= -5.5 + 4m Add 8 on both sides 4 1/2m = 2.5 + 4m Subtract 4m on both sides 1/2m = 2.5 Multiply 2 on both s...

When a line intersects another forming a 90 degree/ right angle.

Work = Force x Distance 115 x 15 = 1,725 20 x 10 = 200 Obviously pushing 115 N over 15 m

Why don't you use the conversions I told you: 1 liters = 1000 milliliters so 4,200 milliliters = 4.2 liters (0.2 liters = 200 mL)

I'm afraid nothing returned that was useful to me, but thanks for the suggestion.

Thankyou soooo much! I really appreciate your help

Thankyou, that helped so much.

Oh my gosh yes! Thankyou Dr. Bob, you are truelly my saint.

I'm not sure why, I think I just had a brain spasm. Some reason I always think of converting mols to liters and I had it in my head that it was a 1:1 relationship but I think its 22.4L only when it applies to a gas?

4-(-3)2 ÷ (-7x4+3) 4-(-6) / (-25) 10/-25 = -2/5 The reciprocal is -5/2 or -2.5. Hope this helps.

Thankyou very much for clearing that up.

Actually Jerome, I think all you have to do is convert 7/8 into a percent and add it to 4. So 7/8 = .875 + 4 = 4.875 or 487.5 percent.

I think you should just know ratios for this. If its 30-60-90 and b= 15, than A= 15/2=7.5 You get this because A is half the size of B. C is three times the size of C, so 7.5 x 3 = 22.5 So 7.5,15,22.5 Hope this helps.

9m+n=24 m-8n=27 n= 24-9m 27= m - 8(24-9m) 27= m - 192 - 72m 219= -71m so m = 3.0845 Double check by entering this into the other equation. 9(-3.0845)+ (24-9(-3.0845) -27.7605 + 24 - -27.7605 = 24. so m = -3.0845 -3.0845 - 8(n)= 27 -8n= 30.0845 n= - 3.7606...
