Answer:
150 boys were enrolled in 2012
Step-by-step explanation:
Let the number of boys enrolled in 2012 be x
Let the number of girls enrolled in 2012 be x + 200
Ratio of boys to girls in 2012 enrollment = 3/7
Now;
3/7 = x/x + 200
7x = 3(x + 200)
7x = 3x + 600
7x - 3x = 600
4x = 600
x = 600/4
x = 150 boys
Hence, 150 boys were enrolled in 2012
Answer:
33(5/6) sq miles
Step-by-step explanation:
Area = LxW
812 = 24xW
Divide by 24
W = 33.8333333 ( 33 (5/6)
8 is non repeating
3 is repeating
For nominator subtract the non repeating (83-8 = 75)
For denominator : one 9 for each non repeating,one zero for each repeating (only 3 is repeating,then one zero)
75/90 = 5/6
It equals 5,800. Good Luck In School!
20 : 0.75 = 40 : 1.5 = 80 : 3
D because perpendicular lines intersect at a right angle and D is the only shape with right angles.
