There are 80 students in the sixth grade at Baker Street School, and 50% of thern take notes with a pencil sixth-grade students who take notes with a pencil. how many sixth grade students take notes with a pencil? ​

I think the answer would be 40

 Hello, There! your Answer is Below

40 Is your Answer

Step-by-step explanation:

Step 1: Our output value is 80.

Step 2: We represent the unknown value with XStep 3:

From step 1 above,$80=100

Step 4: Similarly, x=50

Step 5: This results in a pair of simple equations:This results in a pair of simple equations:

$80=100\(1)

$x=50(2)

Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both

equations have the same unit (%); we have

80/x = 100%/50%

Step 7: Again, the reciprocal of both sides gives

x/80 = 50/100

x=40$

Therefore, 50%of 80i s 40

e^-kt = n/n0 = 0.79  

-kt = ln 0.79  

t = - ln 0.79/0.0001  

= 2357 years
