6.) Gerry used the diagram to compute the distance from Ferris to Dunlap to Butte. How much shorter is the distance from Ferris to Butte than the distance Gerry found?

A. 91 mi

7.) A cable 16m long runs from the top of a utility pole to a point on the ground 4m from the base of the pole. How tall is the utility pole, to the nearest tenth?

A. 15.5 m
B. 16.5 m
C. 256 m***
D. 16 m

Answer 1

#1 ok
#2 Any decimal which repeats is rational
#3 nope. √150 = 25√2 -- irrational
#6 no diagram
#7 How can you possibly say that the pole is 16 times as high as the length of the cable? You are clearly just guessing here. When you get an answer, take a step back and see whether it makes any sense. If the height is h, then

h^2+4^2 = 16^2
h^2 = 250
h ≈ 15.8

Answer 2

ok I think 7 is B is that correct now I tried the formula for hypotenuse

Answer 3

and is 16.5 closer to 15.8 than 16?

Answer 4

no I think its closer to 16

Answer 5

for number 2 so it would be rational since the number continues to go without reaping is that right?

Answer 6

if it goes on without repeating, it is irrational.

If it reaches a digit of group of digits that repeat forever, it is rational.

Answer 7

The answer for 7 is D because 15.8 is closer to 16 than 15.5.

Answer 8

The answer for number 7 is B because 16^2+4^2=272^2 √272 =16.4924225 so you have to round to the nearest tenth which is 16.5. So there for it is B.)16.5
