Use TrianCal to draw a triangle with phi as Great Piramid (minimum perimeter given 2 equal heights) = maximun stability.
NOTE: Phi=(1+√5)/2≈1.62 and acos(1/Phi)≈51.83º
Answer:2.4km/hr
Step-by-step explanation:
Speed = distance/time
Speed =4.6/2
Speed=2.3km/hr
6x+8=100
6x=92
X= 15.33 or x =15 1/3
He makes 125 on the first ten and 60 on the next three so 185
Answer:
There is 384.75 sq feet area of grass in the rectangular yard.
Step-by-step explanation:
The dimensions of the rectangular yard = 25 ft x 19 ft
The Area of the yard = LENGTH x WIDTH
= 25 ft x 19 ft
= 475 sq feet
or, the area of the rectangular yard = 475 sq feet
Now, the side of the square covered with flower garden = 9.5 feet
So, area of the flower garden = 9.5 ft x 9.5 ft = 90.25 sq ft
Now, Area Covered with Grass = Total area of Yard - Area of flower garden
= 475 sq feet - 90.25 sq feet
= 384.75 sq feet
or, the area covered with grass = 384.75 sq feet
Hence, there is 384.75 sq feet area of grass in the rectangular yard.
