Answer:
1 inch = 2.54cm
You are given 10cm wide and 60 inches wide, so you have to convert either the 60 inches or the 10cm to a similar unit to figure out the scale factor. I will convert the 60 inches.
60 x 2.54 = 152.4cm
152.4/ 10 = 15.24 -> Scale Factor
I don't know what you were supposed to work out, but here's some stuff I've worked out for you.
Answer:
that would take 12 hours to burnt the 6inch candle
<u>Answer:</u>
Solve brackets
6(0.66x-3)>8
Multiply 6 with values in the bracket
<em>So, 6x0.66x and 6x-3</em>
4x- 18> 8
Since 4x and 18 are unlike terms, we will take 18 onto the other side, thus:
4x>8+18
4x>26
<em>Now to find the value of x, divide 4 on B.S</em>
x>
X> 6.5
OR in 'fraction form'
X>
Hope this helps :D
12/6 = 2
9x2= 18
