Answer:
120
Step-by-step explanation:
Given data
36 members are equivalent to 30%
Let the total number of students be x
Hence
30% of x= 36
30/100*x= 36
0.3x= 36
divide both sides by 0.3
x= 36/0.3
x= 120 students
Hence the total number of students is 120

Answer:slope is 0.4
Step-by-step explanation:
y2-y1 divided by x2-x1
2-4/0-5=0.4
The applicable decay formula is:N = No*e^(-kt)WhereN = Mass left after time tNo = Original massk = constantt = half lifeUsing the values given,N/No = e^(-0.1446t) = 1/2ln (1/2) = -0.1446 t *ln e^1-0.6931 = -0.1446 tt = 0.6331/0.1446 = 4.79 daysTherefore, half-life is 4.8 days.
Answer:
3(x + 2)(x - 6) = 0
Step-by-step explanation:
We see that if x + 2 = o then x= -2
and if x - 6 = 0, x = 6.
