Answer:
150
Step-by-step explanation:
30 + 30 + 45 + 45 = 150
The formula for the area of a hexagon is
![A=\frac{3\sqrt[]{3}}{2}s^2](https://tex.z-dn.net/?f=A%3D%5Cfrac%7B3%5Csqrt%5B%5D%7B3%7D%7D%7B2%7Ds%5E2)
where 's' is the length of one side of the regular hexagon.
The side of our regular hexagon is 2 feet, therefore, its area is
![\begin{gathered} A=\frac{3\sqrt[]{3}}{2}\cdot(2)^2=6\sqrt[]{3} \\ 6\sqrt[]{3}=10.3923048454\ldots\approx10 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20A%3D%5Cfrac%7B3%5Csqrt%5B%5D%7B3%7D%7D%7B2%7D%5Ccdot%282%29%5E2%3D6%5Csqrt%5B%5D%7B3%7D%20%5C%5C%206%5Csqrt%5B%5D%7B3%7D%3D10.3923048454%5Cldots%5Capprox10%20%5Cend%7Bgathered%7D)
The exact area of the hexagon is 6√3 ft², which is approximately 10 ft².
Answer:-3
Step-by-step explanation:
its just adding and subtracting
Remark
Start by figuring this out for 1 car. Worry about the 7 part when you find 1.
This problem is used quite frequently in physics. For example resistors in parallel use the same equation.
Formula
1/frank + 1/carla + 1/missy = 1/ time taken to do 1 mar.
Givens
Frank = 2 hours
Carla = 2 hours
Missy = 3 hours.
Substitute and Solve
1/2 + 1/2 + 1/3 = 1/Three_together.
3/6 + 3/6 + 2/6 = 1/Three_together.
8/6 = 1/Three_together. Cross multiply
8 * Three_Together = 6*1
8 * Three_Together = 6 Divide by 8
Three_Together = 6/8 = 3/4 = 0.75 hours. or 45 minutes for 1 car
Seven Cars
For 7 cars multiply 0.75 by 7
7 * 0.75 = 5.25 hours. <<<< Answer
The answer to this problem would be it would be a 20% discount
