The area of the pentagon is 140
Answer: -21.125 or -21 1/8 degrees
Explanation: Divide the number of degrees (-169) by the amount of time it was snowing (8) to get the answer (-21.125).
-169÷8=-21.125
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:
the answer is c.768
Step-by-step explanation:
Answer:
a.(-b) ( third choice)
explanation:
-a+b - there is no plus sign for -a.b.
not -a+b
(-a)(-6)=6a (-negative sign and -negative sign=+positive sign)
