question!
okay. Now I'll know around when I can ask questions.. and since the time zones are different I was just wondering. My question has been answered even though it has nothing to do with hw.. but I couldn't find the answer on the website so I had to ask you here. thanks!

question!
What are the operating times at Jiskha when I can actually get a response within half an hour?

Math
you question doesn't make much sense. how can (x + 4) be the exponent from the base of 3?

Math
ohh... okay thanks so much! i really appreciate it. it makes sense now. ;)

Math
correction* 3 meters is too less room.

Math
Okay. That's true, 3 meters is a pretty wide space. I figured out the first dimension, it's 29.8 m. I still need the second dimension so I can figure out the area of the fenced space.

Math
A tennis court is 23.8 m by 11 m. A tennis club has 3 courts side by side in a fenced area. The courts have 3 m between them and 3 m around the outside. What are the dimensions of the fenced space? Please and thank you!

The product of -7 over 12 and a mystery number is -1 over 2. What is the number?

Math
What numbers have no recrpricol?

-6 divide n = -9 and 5 over 6

Math
Okay. Thank you very much. I had a feeling that the answer at the back was wrong, I tried many solutions, and it didn't work. So you're probably right. :)

The question says that the diameter is 8 cm, and then it asks to fnd the perimeter. I found the answer using your formula but when I checked the back of the book, it said the answer was 20.56 cm, not 25.12 cm.

Math
How do you calculate the perimeter of a half circle?

Science
okay. I think I understand it now. Thank you.

correction..: how would you solve this equation? the height of a triangle is 2m more than the base. The area is 17.5m^2. Find the length of the base. it's height.. not measurement..
