(i) the number of students who passed in the first and in the second division
76+95=171 students
(ii) The ratio of the number of students who passed in the first second and in the third division.
RATIO is 4:5:(25/19) or 4:5: 1.3157894…….
225-29=196 (29students failed)
196-25=171. (Subtract 25 students from the 3rd division)
4x+5x= 171 (171 students from 1st and second division)
9x=171
X=19
4x19=76 5x19= 95 1.31578.....x19= 25
Answer:
yourself 1 ticket.
16 left
3 friends x 5 tickets ,=15
16-15= 1
Just my thought.
Unless you don't go. Then your remainder is 2. But, it said share not give away. So I am thinking you keep a ticket.
So sneaky
Good luck
Answer: Subtract y from both sides of the equation.
x=12-y
x-y=2
The expression calculates the population x years from now will be given as y = 1024 (0.75)ˣ.
<h3>What is an exponent?</h3>
Consider the function:
y = a (1 ± r) ˣ
Where x is the number of times this growth/decay occurs, a = initial amount, and r = fraction by which this growth/decay occurs.
If there is a plus sign, then there is exponential growth happening by r fraction or 100r %
If there is a minus sign, then there is exponential decay happening by r fraction or 100r %
The population of sea turtles decreases by 25% per year. The population size is currently 1,024.
Let y be the population of sea turtles and x be the number of years.
Then we have
y = 1024 (1 - 0.25) ˣ
y = 1024 (0.75) ˣ
