Answer:
here
Step-by-step explanation:
I don't think it simplifies, it should be 103/50
1/4 of 80 is 20 so there's 60 left the second day.
2/5 of 60 is 24.
60-24=36
There are 36 students left after the second day.
Your final answer would be 2/3.
The LCD would be 12.
You would have to multiply both the top and bottom of 1/4 to get the denominator to 12.
To do this, you multiply it both the numerator and denominator by 3.
This would leave you with 3/12.
The second fraction already has a denominator of 12 so we will just leave it as is.
Then you add.
3/12 + 5/12
This would give you
8/12
Then you simplify it or "reduce it" by dividing both the top and bottom by 4 to get your final answer.
2/3
Height in feet is represented by
The height of the ball is 0 feet when it hits the ground.
So we replace height f(x) by 0 and solve for x to find the time taken to reach the ground
( divide by -16 on both sides)
Now factor it
(x-6)(x+1) =0
x-6 =0 and x+1=0
x=6 and x=-1
Time cannot be negative so we ignore -1
x = 6 seconds
It will take 6 seconds for the ball to reach the ground.
There would be 390,221 adults because 538,381 - 148,170 = 390,221
