-7, -4/5, 0, 1/2, 7/8, and 2
Answer:
Sue = 25.75
Dave = 29.5
Tom = 19.75
Sue = s
Tom = t
Dave = d
Step-by-step explanation:
s+t+d = 75
s-6=t
d +16 = s+t
d+16+d= 75
2d = 59
d = 29.5
t = s-6
t+s = 45.5
s-6+s= 45.5
2s = 51.5
s= 25.75
t= 19.75
Answer:
Sam ate the most pizza.
Step-by-step explanation:
Mathew: 0.8 is equal to 80%
To get a percentage, you need to move the decimal two places to the right.
Lily: 3/4 = 75%
George: 77%
Sam: 82%
A.) P(t) = 130t - 0.4t^4 + 1200
The population is maximum when P'(t) = 0
P'(t) = 130 - 1.6t^3 = 0
1.6t^3 = 130
t^3 = 81.25
t = ∛81.25 = 4.3 months.
Maximum population P(t)max = 130(4.3) - 0.4(4.3)^4 + 1200 = 1,622
b.) The rabbit population will disappear when P(t) = 0
P(t) = 130t - 0.4t^4 + 1200 = 0
t ≈ 8.7 months
