A^2 + b^2 = c^2
297^2 + 394^2 = C^2
88209+155236=243445
take the square root of 243445
you get 493.4
which in your answer they're rounded
so your answer is
C. 493
Answer:
n=16 kg
c=44 kg
Step-by-step explanation:
Let
n=nuts at $2.50 per kg
c=cereal at $1 per kg
n+c=60 (1)
2.5n + c=1.40(60) (2)
From (1)
n=60-c
Substitute n=60-c into (2)
2.5n + c=1.40(60)
2.5(60-c) +c=84
150-2.5c+c=84
-1.5c=84-150
-1.5c= -66
Divide both sides by -1.5
c=44 kg
Substitute c=44 into (1)
n+c=60
n+44=60
n=60-44
=16
n=16 kg
The amount of nuts is 16 kg and cereal mixture is 44 kg to obtain 60 kg of a mix that will sell for $1.40 per kg.
It’s c. $36.71 hope this helps :)
Answer:
54% of the students from the high school go on to college
Step-by-step explanation:
We have these following percentages:
30% of the students from a high school face a disciplinary action of some kind before they graduate. Of those, 40% go on to college.
70% do not face action, and of those, 60% go to college.
What percent of the students from the high school go on to college?
Sum of 40% of 30%(face disciplinary action) and 70% of 60%(do not
face disciplinary action). So
54% of the students from the high school go on to college
