Answer:
x=141
Step-by-step explanation:
(n-2)•180 = Sum of all the interior angles
n = # of sides
(7-2)•180
5•180
900= Sum of all the interior angles
Add all the angles and equal them to 900
125+122+131+x+7+x+107+x-15=900
Add all the numbers up first on the left side
477+3x=900
3x=423
x=141
Answer:
Step-by-step explanation:
so llets find what 15% of 60% really is,
0.15*0.60=0.09
0.09 AKA 9%
so since 9% of people didn't show up we can subtract 9% from 60%
so 60-9=51
51% of setas are taken
to find the percent of seats still empty, subtract 100 form 51
so
100-51=49
49% of seats are still empty
Hope this helsp!
Step-by-step explanation:
-9x+17
When x =-4, then
-9x+17
-9×-4+17
36+17

Answer:
3576 infected people
Step-by-step explanation:
We have to apply the following formula, which tells us the number of healthy people:
A = p * (1 - r / 100) ^ t
where,
p = initial population,
r = rate of change per period (days)
t = number of periods (days)
Now, we know that the initial population is 3,662 but there are already a total of 36 infected, therefore:
3662 - 36 = 3626
that would be our p, now, we replace:
A = 3626 * (1 - 34/100) ^ 9
A = 86.16
Therefore, those infected would be:
3662 - 86.16 = 3575.84
This means that there are a total of 3576 infected people.
