Answer:
4√34
Step-by-step explanation:
Let the unknown side be y
y^2 = 20^2 + 12^2
y^2 = 400 + 144
y^2 = 544
Take the square root of both side
y = √544
y = √(16x34)
y = √16 x √34
y = 4√34

Answer:
B (2 violet)
Step-by-step explanation:
Let the colors be represented by their first letter. Then the balances give rise to two equation:
o +y +b +v = r +g +b
o +y +v = g +v
Subtracting the second equation from the first gives ...
(o +y +b +v) -(o +y +v) = (r +g +b) -(g +v)
b = r +b -v
Adding v-b to both sides, we have ...
b +(v -b) = r +b -v +(v -b)
v = r
Multiplying this result by 2, we can match the final balance:
2r = 2v . . . . . . . choice B

Answer:
$46.42
Step-by-step explanation:
a=price after discount (without sales tax)
a/55=20/100
100a=55·20
100a/100=1,100/100 (the 1,100 is from the 55·20)
You get 11 and then you have to subtract 11 from 55.
55-11=44, so a=44
Then you multiply 44·0.055 (you get 0.055 because you have to make 5.5% a decimal. You get 2.42.
You add 2.42 and 44 and you get $46.42
