What is the difference of the lengths of BD and CE ? Use the value (pie) = 3.14, and round the answer to two decimal places.
lys-0071 [83]

Answer:

1.57 units


Step-by-step explanation:

The formula for arc length is given as:

Arc Length = \frac{\theta}{360}*2\pi r

Now,

  • Arc length of BD = \frac{45}{360}*2(3.14)(6)=4.71
  • Arc length of CE = \frac{45}{360}*2(3.14)(8)=6.28

The difference in CE and BD is 6.28-4.71=1.57

Second answer choice is right.


***** <u><em>CE falls in the larger circle whose radius is AB + BC = 6+2=8</em></u>

<u><em>BD falls in the smaller circle whose radius is AB=6</em></u>

One photo shop charges $0.36 per print. Another photo shop charges $2.52 plus $0.08 per print. Juan finds that the cost of print
koban [17]

Juan have to print 9 photos.

<u><em>Explanation</em></u>

Suppose, Juan have to print x number of photos.

First photo shop charges $0.36 per print.  So, the total cost to print x number of photos in this shop =0.36x dollar.

Second photo shop charges $2.52 plus $0.08 per print. So, the total cost for printing x number of photos = (2.52+0.08x) dollar

As, the cost of printing is the same at both shops, so.....

0.36x=2.52+0.08x\\ \\ 0.36x-0.08x= 2.52\\ \\ 0.28x=2.52\\ \\ x=\frac{2.52}{0.28}=9

So, Juan have to print 9 photos.
