Answer:
250 Students are musicians, 200 are not.
Step-by-step explanation:
Decimal Version:
If we take "5 out of every nine students are musicians" and make this a fraction we get 5/9. 5/9 as a decimal is approximately 55.555555555556. 55.555555555556% of 450 = 250. So that means 250 students are musicians.
Fraction Version : See attached image.
So, the question is 63 is 30% of what number?
That can translate to the equation
63 = 30% · x or 63 = 0.3x
Divide by 0.3 and you get x = 210.
There are 210 students in band.
Answer:
Step-by-step explanation:
area=15×9+1/2×6×9
=135+27
=162 m²
Base = 12ft
Height = 19ft
Perimeter = 12 ft + 16 ft + 27 ft = 55 ft
Area = 1/2(12 ft)(19 ft)
Area = 1/2 (228 ft)
Area = 114 ft²
Distribute
a(b+c)=ab+ac
2(10-r)=20-2r
now we have
8+20-2r
28-2r
