Answer:
n = 7
Step-by-step explanation:
3(n - 4) = 9
3n - 12 = 9
3n = 9 + 12
3n = 21
n = 21 ÷ 3
n = 7
Answer:

Step-by-step explanation:
we know that
The exponential function is of the form

where
a is the initial value
b is the base
In this problem we have
a=200 birds
b=100%+4%=104%=104/100=1.04
substitute

Let change of variables

where
b is the amount of birds in the flock
d is the number of days since the 200 birds started
Answer:
It should just be the radius
Step-by-step explanation:
The radius is half the diameter of the circle and all you’re doing is taking the radius multiple times
rounding to nearest 10 to any number follow these rules
1. if number ends 0 , 1 , 2 ,3 4 , 5 take number down to nearset multiple of 10
2. if number ends with above 5 take the upper number multiple of 10
so here
413 + 35.6 + 998.5 + 376 + 85.3
= 410 + 40 + 1000+ 380 + 90
= 1920
