4.509 is greater that 4.508 and less than 4.512
The cost of bananas = $ 3.48
This can be written as :
this number written in expanded notation as : (3 × 1) + (4 × 0.1) + (8 × 0.01)
3+0.4+0.08 = 3.48
Hence, 1st option is correct.
-17 is less than -1 so you will use the less than sign (<)
Answer: 17 __<__-1
< is less than
> is greater than
= is equal to
<span>≥ is greater than or equal to</span>
Recall that:
sin(A + B) = sinAcosB + cosAsinB
Therefore:
sin11°cos19° + cos11°sin19° = sin(11° + 19°)
= sin30° = 0.5
I hope this explains it.
