Answer:
a) (x/7)^1/9=y
Step-by-step explanation:
f(x) = 7x^9
x/7= 7y^9/7
(x/7)^1/9=(y^9)^1/9
(x/7)^1/9=y
f^-1(x) is a fuction because it passes the vl test
So the sale price was $160 and the shipping fee was $8.
They are asking what percent of the sales price was the shipping fee...
or in other words, what percent of 160 is 8?
Divide 8/160
You should get 0.05, or 5% :)
Currently 100 students can eat for 20 days, so we need to find the number of days 125 students can eat.
Originally:
100 students eat for 20 days
New:
125 students eat for x days. Multiply original number of students by original number of days which will give the total amount of students per day. Then divide the total amount of students per day by the new number of students to find the new number of days.
x= (100 students * 20 days)/ (100+25)
x= (100 * 20)/ 125
x= 2000/125
x= 16 days
ANSWER: 125 students can eat for 16 days.
