Answer:
181.044m²
Step-by-step explanation:
First, work of the surface area of the base (bottom rectangle area)
Formula : base × height
6×2=12m²
Formula : LW+L
For the 8.8 bit i got 83.734 (sorry i can't be asked right now to put down all my working out)
and for the 9 i got 85.31
add them all together we get 181.044
Answer: 720ways, 24ways
Step-by-step explanation:
Given the seven letter words "SYSTEMS", if E is always occurring before M it means E and M will always be together therefore they letter 'EM' will be taken as an entity to five us 6letters i.e SYST(EM)S.
This can then be arranged in 6!ways
6! = 6×5×4×3×2×1 = 720ways
Similarly, if the E somewhere before the M and the three Ss grouped consecutively, this means E and M must always be together as well as the Ss to give (SSS)YT(EM).
This means that the letters in the bracket can be taken as an entity to give a total of 4 entities. This can them be arranged in 4! ways.
4! = 4×3×2×1
4! = 24ways
Step-by-step explanation:
(3⁸×3⁴)/(3²×3⁸)
3¹²/3¹⁰
3¹²-¹⁰
3².
hope this helps you.
