2. helpmeplz311

3. helpmeplz311

I beg of you.

4. AriPotta

which ones do you need help on?

5. helpmeplz311

um, all of them except number one on page b

6. AriPotta

do you know the formula for the area of a square?

7. helpmeplz311

no,i dont remember

8. AriPotta

l x w = a, remember? but for a square, since the length and width are equal, you can just say s^2 = a

9. helpmeplz311

Ohhh.

10. helpmeplz311

yes. i was wondering however about the problems at the top of page b

11. AriPotta

oooh i misread what you said. sorry, i'm tired

12. helpmeplz311

its alright

13. helpmeplz311

tnx for taking a look

14. AriPotta

15. AriPotta

so 7^2 + 2^2 = ?

16. helpmeplz311

is that no one on page b?

17. AriPotta

yea. number 1, page b

18. helpmeplz311

thanks:)

19. AriPotta

do you know what the answer is? or what you think the answer is?

20. helpmeplz311

yup,7.2

21. helpmeplz311

22. AriPotta

ehh, i'd put 7.3 unless your teacher asked you not to round?

23. helpmeplz311

well, i am allowed to use a calc, and it said 7.2......

24. AriPotta

7.2801..., that's why i said 7.3, but put 7.2 if you want :)

25. helpmeplz311

ill put 7.3:)

26. helpmeplz311

ok, another one i need urgent help on

27. helpmeplz311

number two on page b

28. AriPotta

mmk, which one is that?

29. helpmeplz311

and then, number two on page a., plus number three on page a

30. helpmeplz311

my most urgent four.

31. AriPotta

4 on a?

32. helpmeplz311

yes

33. helpmeplz311

i mean two and three on a

34. AriPotta

wait, so you don't need help on 4?

35. helpmeplz311

technically,all of them i need help on, but im doing four today and waking upmearly tomorrow to do the others

36. helpmeplz311

unless you fel kind enough to help memonthem all

37. helpmeplz311

but i doubt it

38. helpmeplz311

since ur tired

39. AriPotta

we're doign the same thing as the other one i posted

40. AriPotta

doing*

41. helpmeplz311

whic one is that?

42. AriPotta

that's number 4 on page a

43. AriPotta

so 13^2 + 12^2 = ?

44. helpmeplz311

well, 11.48 144

45. helpmeplz311

155.48?

46. AriPotta

remember Pythagorean theorem... a^2 + b^2 = c^2 so 13^2 + 12^2 = c^2 169 + 144 = c^2

47. helpmeplz311

oh

48. AriPotta

313 = c^2, so what does c equal?

49. helpmeplz311

are a and b aleeady squared?

50. helpmeplz311

o square 313

51. AriPotta

right, so what's the square of 313?

52. helpmeplz311

9769

53. helpmeplz311

54. AriPotta

i meant square root, sorry

55. helpmeplz311

o

56. helpmeplz311

i entered '313^2' into the search engine

57. AriPotta

yea, i know what you did, but this is what you need to do: $\sqrt{313}$

58. helpmeplz311

ohhh duh. *hits own face*

59. helpmeplz311

17.69

60. AriPotta

yup

61. helpmeplz311

yay:) *writes*

62. helpmeplz311

thatd be which 1?

63. AriPotta

that was 4 on page a

64. helpmeplz311
65. AriPotta

that was what you used to get the answer to number 4

66. helpmeplz311

Ari, srry, im having trouble with number 2

67. helpmeplz311

o

68. AriPotta

ok

69. helpmeplz311

tnx:)

70. AriPotta

71. helpmeplz311

Ari, the one you just hlped me on, was that the one withbthencoordinate points listed or the one about george?

72. AriPotta

so the hypotenuse is 17...do you see how i got the the lenght of the one leg?

73. helpmeplz311

and tnx

74. AriPotta

with the coordinates listed

75. helpmeplz311

tnx,let me look at ur most recent snapshot

76. helpmeplz311

ok.mcan you explain what x is?

77. AriPotta

yea, i was just asking you if you knew how i got 15 for the length of the one side? because if you know this, you can basically do any question similar to this

78. helpmeplz311

oh.no. how?

79. AriPotta

did you notice how the area of that square was 225? how can we find the side length of a square?

80. helpmeplz311

sq root oof area

81. AriPotta

yep, and that's how we got 15, does that make sense?

82. helpmeplz311

15

83. helpmeplz311

yes,ma'am

84. AriPotta

so if we know the hypotenuse is 17, and a leg is 15...how can we go about finding the other leg length?

85. helpmeplz311

15+x=17?

86. AriPotta

what's the Pythagorean theorem?

87. helpmeplz311

a^2+b^2=c^2

88. helpmeplz311

15^2+b^2=17^2?

89. AriPotta

yep

90. helpmeplz311

yay so i solve?

91. AriPotta

if you know how to. show me what you think you do

92. helpmeplz311

3.8-4.1

93. AriPotta

you're doing the square root again!

94. helpmeplz311

ii mean the other way around

95. AriPotta

don't! lol

96. helpmeplz311

srry :s im addicted to sqnroots i think

97. helpmeplz311

lol

98. helpmeplz311

er,sobhow then?

99. AriPotta

what's 15^2?

100. helpmeplz311

oooh 225

101. AriPotta

and what's 17^2?

102. helpmeplz311

289

103. AriPotta

right, so 225 + b^2 = 289. what do we do now?

104. helpmeplz311

subtract

105. helpmeplz311

289-225

106. helpmeplz311

=64

107. AriPotta

so b^2 = 64...what does b equal?

108. helpmeplz311

8

109. AriPotta

yep

110. helpmeplz311

:0 lol all that for 8

111. AriPotta

115. AriPotta

3 on page a?

116. helpmeplz311

yes

117. AriPotta

i think all you have to do for that is $\sqrt{89}$

118. helpmeplz311

119. AriPotta

i know, what's the square root of 89?

120. helpmeplz311

9.43

121. AriPotta

144. helpmeplz311

doing it...

145. AriPotta

"as the crow flies" i have no idea what that means lol

146. AriPotta

oh wait! that's the hypotenuse!

147. helpmeplz311

same:0

148. AriPotta

149. helpmeplz311

oh

150. helpmeplz311

explain plz?

151. AriPotta

well crows can fly over water and stuff. we'd have to walk around it. so "as the crow flies" is through the water or whatever, so it's the hypotenuse

152. helpmeplz311

ok.tnx the kms i just draw on the plane?

153. helpmeplz311

him going south then east?

154. AriPotta

south is down, east is right
