Answer: About 30 years
Step-by-step explanation:
We would apply the formula for determining compound interest which is expressed as
A = P(1+r/n)^nt
Where
A = total amount in the account at the end of t years
r represents the interest rate.
n represents the periodic interval at which it was compounded.
P represents the principal or initial amount deposited
From the information given,
P = 10000
r = 8% = 8/100 = 0.08
n = 1 because it was compounded once in a year.
A = 100000
Therefore,
100000 = 10000(1+0.08/1)^1 × t
100000/10000 = (1.08)^t
10 = (1.08)^t
Taking log to base 10 of both sides, it becomes
Log 10 = log 1.08^t
1 = t × log 1.08 = 0.03342t
t = 1/0.03342
t = 29.9

Answer:
452.16 m³
Step-by-step explanation:
d = 3h = 3×4m = 12 m
r = d/2 = 12m/2 = 6 m
V = Ab×h = π·r²·h
= 3.14×36m²×4m
= 452.16 m³
Answer:
4
Step-by-step explanation:
The area, a of the room is 8* 5.5
a = 44 sqaure feet
one square foot of tiles are sold in packages of 12
To get the number of packages needed, simply divide the area of the room by 12
This gives:
44/12 = 4
= 3.67 round up to the nearest whole number
= 4
