24) 49pi / approximately 153.94 ft
Answer:
3
Step-by-step explanation:
3+3+3+3+3+3=18
You have to test dp/dt between these intervals
(-inf,2)
(2,10)
(10,inf)
if dp/dt is positive then the population is increasing with respect to time in that interval
Answer:
see below
Step-by-step explanation:
Let N = how much Nellie spends
Let D = how much Debbie spends
Part A
Nellie spends $122 more than Debbie.
N= D +122
Their total expenses amount to $840.
N+D =840
The two equations are
N= D +122
N+D =840
Part B
We can substitute the first equation which is solved for N into the second equation. Every place we see an N in the second equation, we replace it with D+122
Part C
N= D +122
N+D =840
(D+122) +D = 840
Combine like terms
2D +122 = 840
Subtract 122 from each side
2D+122-122=840-122
2D =718
Divide by 2
2D/2= 718/2
D =359
Debbie spends 359
Answer:
85751
Step-by-step explanation:
81924
+ 3827
_______
85751
- Start from the right side, 4 + 7 = 11, but the 1 is carried over
- 2 + 2 + 1 = 5
- 9 + 8 = 17, but the 1 is carried over
- 1 + 3 + 1 = 5
- 8 + 0 = 8
Thus, the answer becomes 85751.
