In 1980, wind turbines in Europe generated about 5 gigawatt-hours of energy. Over the next 15 years, the amount of energy increased about 59% (each year). How many gigawatt-hours were generated
So we see the ratio of the sides of two similar octagons is 2:5 so let's say the first octagon has a side of 2 and the other has a side of 5. 2*8 = 16 and 5*8 = 40. 16:40 = 4:10 = and is again 2:5. So the answer is 2:5.
Answer:
Adelaide's robot is 83.82 centemetres = 0.84 meters
Step-by-step explanation:
2 feet = 60.96cm + 9 inches = 22.86cm therefore Adelaide's robot is taller
2 is the answer to this equation
Answer:
a = 4h.
Step-by-step explanation:
Area (a) = base (b) * height (h).
When h = 2, a = 8:
a = bh
6 = 2b
b = 4
The result 4 is the same for h = 5, 7 and 12.
So the required equation is
a = 4h.
