Answer:
80 ft
Step-by-step explanation:
<em>hey there,</em>

< We know that the rope is 3 pieces long. To make this into an equation, let's just write x + y + z = 150.
Assuming "y" is our second piece, we can tell y = 2x, because it is two times the size of the first piece, which is "x". We also know "z" (our third piece): z = 30.
We can try inputting all the things we know now. x + (2x) + 30 = 150. From here, we can find that x = 40. Since y is our second piece, y = 2x, so 2 x (40) = 80. The second piece would be 80 feet long. >

Wow I'd love to go to that store of yours! :P Anyways if you were asking for the new discounted price I solved this equation: 12*0.8 and got $9.60. But if it was asking for <em>how </em> <em>much </em>was discounted, I would do 12*0.2 and $2.40.
Answer:


Step-by-step explanation:
Consider the provided number.
We need to find the approximate value of
to the nearest hundredth.
First find two perfect squares that the irrational number falls between.

118 is lying between 100 and 121, therefore the square root value of 118 will be somewhere between 10 and 11.


118 is closer to 121 as compare to 100.
Therefore, 
Consider the number 
First find two perfect squares that the irrational number falls between.

319 is lying between 289 and 324, therefore the square root value of 319 will be somewhere between 17 and 18.


319 is closer to 324 as compare to 289.
Therefore,
