Answer:
It would be the second option
Step-by-step explanation:
z:28 is the ratio of the shorter triangle's side to the larger triangle's side, so is 27:45.
Answer:
c = 8.14 million×(0.9166)^t
4.83 million
Step-by-step explanation:
Data:
t = y - 2007
c₀ = 8.14 million
c₃ = 23 % less than c₁
Part 1. Calculate c₃
c₃ = c₀(1 - 0.23) = 0.77c₀
Part 2. Calculate r
c₃ = c₀r^t
0.77c₀ = c₀r³
0.77 = r³ Divided each side by c₀
r = 0.9166 Took the cube root of each side
The explicit decay model is c = 8.14 million×(0.9166)^t
Part 3. Prediction
t = 2013 - 2007 = 6
c = c₀r^t = 8.14 million×(0.9166)⁶ = 8.14 million × 0.5929 = 4.83 million
The model predicts that there will be 4.83 million cars for sale in 2013.
Answer: A.
Step-by-step explanation:
Answer:
29
Step-by-step explanation:
Assume the number as x
2x - 9 = 49
2x = 58
x = 29
30 because 2/5 are girls so 3/5 are boys and 24/3 +8 so 1/5=8 so 8*5 + 40 kids
