Answer:
90%
Step-by-step explanation:
first off, if you convert to a fraction you get 36/40. times both of them by 2.5 would give you 90/100.
Answer:
73384 kilotons
Step-by-step explanation:
=> Total amount the 1st year = 90,000
=> Since after the 1st yr, there was a reduction of 4%, so 100% - 4% = 96% or 0.96
=> Total time = 6
We know that the formula of a geometric sequence is;
aₙ = a₁ * r⁽ⁿ⁻¹⁾
In which;
- aₙ = the value that has to be figured out (in this case it would be a₆)
- a₁ = the first term of the sequence (in this case it would be 90,000)
- r = common ration (in this case it would be 0.96)
- n = given time (in this case it would be 6)
Therefore we can finally say;
=> aₙ = a₁ * r⁽ⁿ⁻¹⁾
=> a₆ = 90,000 * 0.96⁶⁻¹
=> a₆ = 90,000 * 0.96⁵
=> a₆ = 73383.54
=> a₆ = 73384 (Rounded to the nearest whole number)
Therefore, rounding the answer to the nearest whole number, the answer would be; 73384 kilotons
Hope this helps! (Btw big shout out to jcherry99 for helping me figure this out!!)
The second one and the last one
You need to post pic of show problem
It would be equal to 0.45 = 45/100 = 9/20
so, your answer is 9/20
