1. ok so 84÷5=16.8 this equals 1/5 of Fiona's saving. to find out 1/8 of the of 3/8 you would divide 16.8 by 3 which equals 5.6. to find out how much money Fiona had you would times that by 8 which equals 44$ to find out how much both of them had you would add 44+84=$128
Answer:
Point P = (-9,11)
Step-by-step explanation:
Point M: (1,3) X and Y have the 2 on the bottom right of them
Midpoint N: (-5,7)
Point P: (X*2, Y*2)
( 1 + X*2 3 + Y*2 )
( _______ ________ ) = (-5 , 7)
( 2 , 2 )
( 1 + X*2 )
( _____ ) = -5
( 2 )
Then multiply the left equation above by 2, and that cancels out the 2 being
divided on the bottom. Also, multiply the -5 by 2 and you get -10
1 + X*2 = -10
+1 +1
__________
X*2 = -9
X = -9
( 3 + Y*2 )
( ______ ) = 7
( 2 )
Then multiply the left equation above by 2, and that cancels out the 2 being divided on the bottom. Also, multiply the 7 by 2 and you get 14
3 + Y*2 = 14
-3 -3
_________
Y*2 = 11
Y = 11
Hope this helps, good luck! :)
Normally if you have the things legnth
and height, you and another thing, then normally the other thing
would be area and you would have 2 given and 1 to solve.
Probably your question is
legnth=?
Height=1.0
decimal part is confusing, I am
guessing that you mean area
area=0.8
so use formula
height times legnth=0.8
1.0 times blank=0.8
divide both sides by 1.0
blank=0.8/1=0.8
blank=0.8
legnth=0.8
Find Angle B: B = 180 - (82+55) = 43. Then apply the law of sines:
b 8 cm
--------- = ----------
sin 43 sin 55
(sin 43)(8 cm)
Solving for b, we get b = ------------------- = 6.66, or 6.7 (cm, to the nearest tenth).
sin 55
-1.55
