Convert "inches" to "feet" here. 30 in 1 ft 30
--------- = --------- = --------- ft
1 12 in 12
Now find the ratio of (30 ft / 12) to 9 ft:
30 ft
------
12 30
==== = ----------- Reduce this fraction; one way would be to
9 ft 12(9) write 30/9 as 10/3:
30 10
------- = ------------ = 5/18 (answer)
12(9) 12(3)
B(t)=50×e^2.5t
e^2.5t = 20
t= ln(20) / 2.5
set B(t)=1000 and solve for t via 1000=50e2.5t
20=e2.5t
ln(20)=2.5t
t=ln(20) / 2.5
Answer:72,000
Step-by-step explanation:
= 4800 × 15
15% of 1085/6 =
15/100 * 1085 6/10 =
= 15/100 * 10856/10 =
= 3/100 * 10856/2 (after simplifying numerator of 15 and denominator of 10)
= 3/100 * 5428 =
= 16284/100 =
= <u>162,84</u>
Answer: 15% of 1085.6 is 162,84 (it's correct - I doublechecked it with calculator)
