Answer:
Step-by-step explanation:
a. 29/8 + 2(19/4) + 3(27/8) = 29/8 + 38/4 + 81/8 = 29/8 + 76/8 + 81/8 = 186/8 in.
b. 186/8 times 2 = 372/8 in
c. the shortest plane would be 27/8 and the largest would be 19/4 or 38/8.
If you subtract the two, you get 11/8. The difference is 11/8 in.
Let the shorter leg = a.
The longer leg, b = a + 4.
The hypotenuse, c = a + 8
a^2 + b^2 = c^2
a^2 + (a + 4)^2 = (a + 8)^2
a^2 + a^2 + 8a + 16 = a^2 + 16a + 64
a^2 - 8a - 48 = 0
(a - 12)(a + 4) = 0
a - 12 = 0 or a + 4 = 0
a = 12 or a = -4
a = -4 is discarded because it is negative.
a = 12
b = 16
c = 20
The lengths are 12 m, 16 m, and 20 m.
You can conclude that it is a isosceles triangle (a triangle with 2 congruent sides)? I'm not sure though. :/
Answer:How often does Old Faithful blow?
The world's most famous geyser, Old Faithful in Yellowstone, currently erupts around 20 times a day. These eruptions are predicted with a 90 percent confidence rate, within a 10 minute variation, based on the duration and height of the previous eruption.
