The answer is A. 1/2=5/10 so 5/10+4/10=9/10
Start with the boys. When the line leader is chosen, there are 10 choices. Then out of the remaining 9, one is chosen to be the caboose. For the girls, the numbers would be 12 and 11. Multiply these numbers to get 1180 possibilities.
Answer:
Step-by-step explanation:
A trapezoid area is a rectangle area plus one or two trianagles areas on each end
Area of a trapezoid =( base 1 x height) + ((1/2)(base 2 - base 1) x height)
solve for height
factor out the height
Area = height [ base 1 + 1/2(base 2 - base 1)]
divide both sides by [ base 1 + 1/2(base 2 - base 1)]
Area / [(base 1 + 1/2(base 2 - base 1)] = height
plug and chug
68 / ( 7 + (1/2)(27 - 7) = height
height = 68 / (7 + (1/2)(20))
= 68 / 17
= 4 ft <-------------- FINAL ANSWER
<h3>
Therefore the present value = $ 80517.91</h3>
Step-by-step explanation:
![PV = FV \div (1+i)^n](https://tex.z-dn.net/?f=PV%20%3D%20FV%20%5Cdiv%20%281%2Bi%29%5En)
Here FV = $83870
i = 6.8% = 0.068
=0.62
Therefore,
![PV=\frac{83870}{(1+0.068)^{0.62}}](https://tex.z-dn.net/?f=PV%3D%5Cfrac%7B83870%7D%7B%281%2B0.068%29%5E%7B0.62%7D%7D)
=$80517.91
Therefore the present value = $ 80517.91
The answer would be 787197
Hope this helps
Have a great day/night
