Answer:
I believe the answer is x=7
Step-by-step explanation:
<em>3x</em> and<em> 4x-1 </em> are corresponding sides and so are <em>14</em> and <em>18</em>.
You cross multiply with the smaller triangle lengths at the top.
3x/(4x-1)= 14/18
Cross multiply to get
18(3x)= 14(4x-1)
54x=56x-14
Subtract 54x on the other side and add 14 to the other (or subtract 56x to the other side)
you get 14=2x and divide 14 by 2 to get x=7
The value of x is 23.
Simply find the scale factor or what was used to dilate △MAH to produce △WCF.
Use the equation copy over the original,

Reduce,

So our scale factor is ¼ or 0.25
So if we use it and multiply the corresponding side of the missing side with the original we get,

Therefore 23 is our missing side! !

Answer:
The heat is produced by a 150-W light bulb that is on for 20-hours is 10200 BTU.
Step-by-step explanation:
To find : How much heat (Btu) is produced by a 150-W light bulb that is on for 20-hours?
Solution :
A 150-W light bulb is on for 20-hours.
The heat produced by bulb is given by,


We know that,

Converting W-hr into BTU,


Therefore, The heat is produced by a 150-W light bulb that is on for 20-hours is 10200 BTU.
