0.55 is equal to 55/100, and by dividing the numerator and denominator by 5, we get 11/20. Hope this helps!
It can be simplified to -5/2.
Literally just put it in your calculator and it will automatically simplify it.
Hi i only know how to do qn 3 and 4
3) 5x = 85 °
x= 85°/5
=17
4)5y =95°
y= 95/5
=19
NOTE* DO NOT WRITE THE ° FOR THE ANSWERS OF QN 3 AND 4
The numbers given in the problem are written in Scientific Notation. By definitios, this is a product of two factors: the first one is a number between 1 and 10, and the second number is 10. This method is used when you have to write numbers that are too large or too small. So, let's write them in their decimal form to understand it better:
5x10^4=50000
7x10^-5=0.00007
3x10^-9=0.000000003
8x10^4=80000
Therefore, the order of <span>5x10^4, 7x10^-5, 3x10^-9, 8x10^4 from least to greatest is:
3</span>x10^-9, 7x10^-5, 5x10^4, 8x10^4<span> </span>
