Answer:

The percentage error of measurement is 5.63 %

Step-by-step explanation:

Given as  :

The measure length of the fence = 150 feet

The actual length of the fence = 142 feet

Let the percentage error in measurement = x

So, x = \dfrac{\textrm measured value - \textrm actual value}{\textrm actual value} ×100

Or, x =  \dfrac{\textrm 150 - 142}{142} ×100

or, x = \dfrac{\textrm 8}{142} ×100

or, x = 5.63 %

Hence The percentage error of measurement is 5.63 %  Answer

Find the nth term of 1,4,3,16,5,36,7
MakcuM [25]

Answer:

64,9

Step-by-step explanation:

From my understanding the pattern would be:

Every other number is the next consecutive odd number,  

( 1, 3, 5, 7 ) are all of the consecutive odds. (So the next odd is 9.  )

That when we get to the part of where we get every other number for the remaining numbers, if you multiply the next even number by itself (square it).  

4, 16, and 36 ( they are all perfect squares.  )

They are the perfect squares of ( 2, 4, and 6) . So it makes sense that ( 8 ) is the next even number and you would square that and get ( 64 )

I hope this makes sense!!

How do you this question? Please explain.
Nuetrik [128]

Answer:

(C) 2√15

Step-by-step explanation:

Recognize that all the triangles are right triangles, so are similar to each other. In these similar triangles, the ratio of the short side to the long side is the same for all.

... CB/CA = CT/CB

... CB² = CA·CT = 10·6 = 60 . . . . . . . . . . multiply by CA·CB; substitute values

... CB = √60 = 2√15 . . . . . . . take the square root; simplify

_____

<em>Comment on this solution</em>

The altitude to the hypotenuse of a right triangle (CB in this case) divides the hypotenuse into lengths such that the altitude is their geometric mean. That is ...

... CB = √(AC·CT) . . . . as above

This is true for any right triangle — another fact of geometry to put in your list of geometry facts.
