The answer is 4! If you plug in the 1 for x in f(x), that gives you 8. Then you plug in f(x) into g(x), you get 4!
Since one page cost $1.25 to print take the cost of per page $1.25 times the number of pages to be printed, in this case eight. $1.25 x 8 = $10.00
Remember there is still a $3.50 added to the cost of the pages printed; thus you have $10.00 + $3.50 = $13.50 which is the total charge.
Answer:
B. 5 1/3
Step-by-step explanation:
5 4/12=5 1/3
Answer: Second option.
Step-by-step explanation:
1. To solve this problem you can applly the quadratic formula, which is shown below:
2. The quadratic equation is:
3. Then:
a=1
b=-10
c=-10
4. Therefore, when you substitute these values into the quadratic formula, you obtain the following result:
x=5±√35
Răspuns:
125%
Explicație pas cu pas:
a și B sunt invers proporționale cu numerele 12 și 15
Proporționalitate inversă:
a = k / y
Prin urmare ;
a = k / 12 - - - (1)
b = k / 15 - - - (2)
Procent care reprezintă a de la b
a = 100%
b = x
k / 12 = 1
k / 15 = x
Înmulțirea încrucișată:
x * k / 12 = k / 15
x = k / 12 ÷ k / 15
x = k / 12 * 15 / k
x = 15/12
x = 1,25
1,25 * 100% = 125%
