Step-by-step explanation:
Domain of the function (-8, positive infinity)
All of the graphs are correct.
A = 2, B = (2, 1)
The vertical asymptote is x = 3.
It would be : 12/46 = 6/23
So, your answer is 6/23
We do
concentration=amount times percent
total concentration=concentration8+concenctration20
so
12 times 8%+x times 20%=16% times (12+x)
x=amount of 20% acis solution
12*0.08+0.2*x=0.16*(12+x)
solve
distribute and simplify
0.96+0.2x=1.92+0.16x
minus 0.96 from both sides
0.20x=0.96+0.16x
minus 0.16x from both sides
0.04x=0.96
divide both sides by 0.04
x=24
24 liters of the 20% was added
Answer:
23pupils
Step-by-step explanation:
Given parameters:
Number of 18th grade boys this year = 18
Percentage decrease = 28%
Unknown:
How many 8th grade teams were there last year = ?
Solution:
Since this is a percentage decrease, ;
Number of pupils this year = Number of pupils last year - (28% x 18 )
18 + (28% x 18 ) = Number of pupils last year
Number of pupils last year = 23pupils
