Answer:
Carole's situation : 2x + 11y = 196
Michele's situation: 10x + 11y = 276
Step-by-step explanation:
If x = cost of 1 cupcake, then 2x = cost of 2 cupcakes and 10x = cost of 10 cupcakes, et.
If y = cost of 1 sugar cookie, then 11y = cost of 11 sugar cookies.
Carole's situation : 2x + 11y = 196
Michele's situation: 10x + 11y = 276
Answer:
The answer is andrew!
Step-by-step explanation:
andrew 10 + 14 + 8 + 12 + 11/ 5 = 11
leroy 2 + 12 + 9 + 11 + 16/5 = 10
Consider a few powers which are close to 120 and 130:
squares:
cubes:
4th powers:
now clearly there is no point of checking 5th, 6th and so on powers of numbers >2.
so check powers of 2:
So we have :
Answer: The answer to the first question is figure 3. Answer for question 2 is also figure 3, but the answer for question 3 is figure 2.
Step-by-step explanation:
Answer:
In 1981, the Australian humpback whale population was 350
Po = Initial population = 350
rate of increase = 14% annually
P(t) = Po*(1.14)^t
P(t) = 350*(1.14)^t
Where
t = number of years that have passed since 1981
Year 2000
2000 - 1981 = 19 years
P(19) = 350*(1.14)^19
P(19) = 350*12.055
P(19) = 4219.49
P(19) ≈ 4219
Year 2018
2018 - 1981 = 37 years
P(37) = 350*(1.14)^37
P(37) = 350*127.4909
P(37) = 44621.84
P(37) ≈ 44622
There would be about 44622 humpback whales in the year 2018
