Maria do 1/2 work in 1 hour
Sasha do 1/3 work in 1 hour
Thus,
1/2+1/3=5/6 work in 1 hour
5/6 work in = 1 hour
1 work in =6/5=1.2 hours =72 minutes
From the statements given in the problem, we can say
that:
Final Score = (total of the remaining scores) * degree of
difficulty * 0.6
Therefore:
97.2 = (total of the remaining scores) * 4.0 * 0.6
total of the remaining scores = 40.5
Therefore the judges could have scored which has a total
of 40.5
Answer:
x = 4, y = 3
Step-by-step explanation:
Equating corresponding coordinates , gives
2x = 8 ( divide both sides by 2 )
x = 4
and
3y = 9 ( divide both sides by 3 )
y = 3
