Answer:
Each litters can be represented as; x and y respectively to the 7% and the 28%
x + y =1
7x + 28y =19.6
This a simultaneous equation and can either be solved by using elimination or substitution method
Using the substitution method
eqn1, x=1-y
putting into eqn2
7(1-y)+28y =19.6
7-7y+28y=19.6
21y=12.6
y=3/5
but x=1-y
so
x=1-3/5
x=2/5
Answer: Yes. (gof)(0) = -5
(gof)(0) means you will find the function of g(f(0)), which means we will find f(0) and plug that value in for x in the function g(x)
We know f(0) is -1, so we can plug -1 into the equation of g(x)
(gof)(0) = (-1) - 4
(gof)(0) = -5
Answer:
0.06, 3/5, 0.8
Step-by-step explanation:
we know that 0.06 is lower that 0.8 so that goes first we work out 3/5 as a decimal so that is 0.6 and we know that is bigger than 0.06 but smaller than 0.8 so it goes in the middle and we know 0.8 is the biggest
to do the fraction par it is 6/100,60/100 and 80/100
i hope that helps
That would be 7% your welcome
