ok\[x/3=30\]

90
anonymous
  • anonymous
Multiply both sides by 3.

which maths paper?
anonymous
  • anonymous
x/3=30 (3) x/3=30(3) x=90

Is the circumference 3.4 meters?
radar
  • radar
Is that the diameter of 3.4 meters
anonymous
  • anonymous
the is question is what is the circumfrence and area of the circle
radar
  • radar
The image is pretty fuzzy. If the diameter is 3.4 meters the circumference is Pi times 3.4. Or 10.68 meters
anonymous
  • anonymous
:D this is so so much help! should i send a better pic
radar
  • radar
O.K, if that is the diameter (3.4), what would be the radius?
radar
  • radar
Area of a circle is:\[A=\pi \times r ^{2}\] where r equals the radius.
anonymous
  • anonymous
would tht be half of tht 3.4
radar
  • radar
yes, radius is one half the diameter.
radar
  • radar
I get 1.7 for the radius. What did you come up with?
anonymous
  • anonymous
im checking now! :)
anonymous
  • anonymous
got the same
radar
  • radar
Good, use that value for r in the equation for area of a circle (6 post up from this one)
radar
  • radar
\[A=\pi \times (1.7)^{2}\]
anonymous
  • anonymous
this will give the answer
radar
  • radar
Yes, what did you come up with?
radar

I got 9 sq

I got 9 sq meters.

The image is really fuzzy. It appears there is a line y=3x-7 and then there appears to be another line intersecting whose equation is y=5x+11. Is this what you see?
anonymous
  • anonymous
the top of the intersecting line is 5-x=11
anonymous
  • anonymous
youre right srry
radar
  • radar
O.K. then we could say at that point where they are intersect y=y 5x-11+3x-7 2x=4 x=2 You could plus that in and solve the y point by inspection I can see that y=-1
radar
  • radar
Wait in minute, did you say it is 5x+11, not 5x-11??
anonymous
  • anonymous
yeah its 5x+11
anonymous
  • anonymous
it looks to me like a geometry question: 5x+11 + 3x-7 = 180
radar
  • radar
Then it would be 5x+11=3x-7 2x=-18 x=-9
anonymous
  • anonymous
From the picture it looks like we have a linear pair (a set of angles that make a straight line) so if we add the angles together we get 180 degrees. Setting them equal gives 5x+11 + 3x-7 = 180 so 8x+4=180. 8x = 176 x = 22 degrees
radar
  • radar
Could be, to me it looked like two intersecting lines, all be it one rotated to align it self with the x axis, and the intersection point was to be solved.
anonymous
  • anonymous
ok so they way tbates did it or the way you did?
anonymous
  • anonymous
I can see that too, but the cursive l beside the line leads me to think its a linear pairs
radar
  • radar
It appears that Tbates has said this was a geometry question, he is probably rights, as theother questions were about circles etc. so I leave you in his capable hands lol
anonymous
  • anonymous
If it were lines on a graph I would have wholeheartedly agreed with your solution radar.
radar
  • radar
Yes, I don't see any coordinates etc. I told christy_white, "maybe" I could help her, in this case maybe not. However, christy, is wanting assistance and appears to be sincerely trying, if you can help, please do.

I'll be around for a bit so post the questions away!
anonymous
  • anonymous
thanks guys ")

next question?
anonymous

Fire away!

Go aheaD Tbates will be back

if each quadirlateral is a parallelgram then find the value of x y z
1 Attachment
anonymous
  • anonymous
tht two problems
anonymous
  • anonymous
tht two problems
anonymous
  • anonymous
If we look at 7 first and specifically z. Again we have a linear pair so: z + 78 = 180
anonymous
  • anonymous
This means z = 102 in the first problem.
anonymous
  • anonymous
for x we have a set of parallel lines cut by a transversal so x = 24 (alternate interior angles) http://www.mathsisfun.com/geometry/alternate-interior-angles.html
anonymous
  • anonymous
Finally all interior angles of a triangle add to 180 so: y + x + 78 = 180 y + 24 + 78 = 180 y + 102 = 180 y = 78
anonymous
  • anonymous
ok i gotcha!
anonymous
  • anonymous
On the second one there's a theorem that states opposite angles in a parallelogram are equal so z = 104. Using alternate interior angles x = 32 and y = 44
anonymous
  • anonymous
Does that make sense?
anonymous
  • anonymous
had to take my dog out for a min. but im looking over it now
anonymous
  • anonymous
yeah i understand
anonymous
  • anonymous
Excellent! Have any more questions?
anonymous
  • anonymous
ohhh yes i have a whole study guide lol! i can take as much help as anyone is willing to give
anonymous
  • anonymous
I'll be around, I'm also answering other questions but I'll be helping you out as well.

the distance btw two points\[( 2, 5)(6, -1)\]
anonymous
  • anonymous
There is a formula for finding the distance between two points and it's: \[distance = \sqrt{(x _{2}-x _{1})^{2}+(y _{2}-y _{1})^{2}}\] \[\sqrt{(5-2)^{2}+(-1-6)^{2}}\] \[\sqrt{(3)^{2}+(-7)^{2}}\] \[\sqrt{9 + 47}\] √56 = 7.48
anonymous
  • anonymous
oops I meant √58 = 7.62
anonymous
  • anonymous
all done?
