Start from inside to the out side of the function;
h(5)=10/5=2
g(h)=g(2)=3*2=6
now, get the f inverse of x;
f(x)=y=x+6
x=y-6
replace x with y and y with x
y=x-6
so f^-1= x-6
so f^-1(g)=f^-1(6)=6-6=0
I am not sure only of the last value, but pretty sure of the rest.

Feliz [49]
So what you do is see all the denomenators and factor them (denomenaotrs are the bottom numbres)

10,4,10,25
10=2 times 5
4=2 times 2
10=2 times 5
25=5 times 5
we need to include all of them so we need at leas two 2's, and two 5's
2 times 2 times 5 times 5=100
leact common denomator is 100

What is 75 percent of 30?
Arturiano [62]
So percent means parts out of 100 so 75%=75/100=3/4
3/4 of 30
'of' means multiply
3/4 times 30=90/4=45/2=22.5
22.5 is the answer (or 22 and 1/2)

If I have 10 dollars and I win 6 out of 10 and lose 4 out of 10 and bet 1$ each trade, how much should there be left after 10 tr
ololo11 [35]

you will be left with 12 dollars.

<u> </u><u>Step-by-step explanation: </u>

Given:

The actual money you have = 10 dollars.

The bet amount for each trade= 1$

For each win, you get extra +1 dollar.

Step 1:

So, you won 6 trades= (6*1)= 6$

Step 2:

For each lose, you loss -1 dollar.

Step 3:

So, you lose 4 trades= (4)*(-1)= -4$

Step 4:

After 10 trades, the money you earned is= 6$ -4$= 2 dollars.

Finally, the total money left after 10 trades is= actual money + earned money                                                

= $10 + $2= 12 dollars.
