Answer:
See the explanation
Step-by-step explanation:
When the numerator is less than the denominator, the result is always less than 1, that is 0. something and this will give a percentage less than 100, but when the numerator is greater than the denominator, th result is greater than 1, and any figure greater than 1 gives a percentage that is greater than 100
example
Numerator >Denominator
=4/2*100
=2*100
=200%
Numerator <Denominator
=2/4*100
=0/5*100
=50%
For this case we can solve the problem by means of the following rule of three:
94 --------> 100%
17 --------> x
Clearing x we have:
x = (17/94) * (100)
x = 18,08510638%
To the nearest tenth of a percent:
x = 18.1%
Answer:
This is 18.1% of his compact discs.
Answer:
A=-2; B=-1
Step-by-step explanation:
3a - 2b + 4 =0
2a -5b -1 = 0
Let's multiple the top equation by 2, and the bottom by -3, and then use addition.
[3a - 2b + 4 =0]*2
[2a -5b -1 = 0]*(-3)
6a-4b+8=0
-6a+15b+3=0
Now add the two equations together:
11b + 11 = 0
Subtract 11 from both sides
11b = -11
Divide both sides by 11
b=-1
Substitute in the first equation:
3a - 2(-1) + 4 = 0
Simplify to get 3a+6 = 0
Subtract 6 from both sides to get 3a = -6
Divide both sides by 3 to get a=-2
