Answer:
Step-by-step explanation:
pythagoras theorem
a^2+b^2=c^2
8^2+x^2=10^2
64+x^2=100
x^2=100-64
x=

Answer:
$200
Step-by-step explanation:
Amanda       Beverly
      9         :       3
difference between Amanda and Beverly = 9 - 3 = 6 portions. 
∴ value of 6 portions = $60
    value of 1 portion  =  $ 60 / 6
                                   = $10
Total no. of portions = 8 + 9 + 3 = 20
 Total sum of money to be shared = value of 1 portion x Total no. of portions
                                                          = $10 x 20
                                                          = <u>$200</u>
