Answer:
54.7%
Step-by-step explanation:
Given the function :
y=2700(0.453)
y represents an exponential Decay function because :
For a growth function ; the function :
y = A(1 + r) where, A is the initial amount and r = growth rate
With this function ; the value in bracket will always be greater Than 1
Hence, when the value after the initial value is less than 1 ; then we have an exponential Decay ;
Where
y = A(1 - r)
Hence, rate, r equals :
1 - r = 0.453
1 - 0.453 = r
r = 0.547
= 0.547 * 100%
= 54.7%
Answer:
69 students attend the camp
Step-by-step explanation:
8% of 75 = 6
75 - 6 = 69
Equation: 450 = 128 + 150 + n
work:
1st step:
128+150 = 278
2nd step:
450-278 = 172
answer: 172
3rd step (checking) :
450 = 128 + 150 + 172
450 = 278 + 172
450 = 450
