The answer would be 28 feet, to get area you do length times width, 7 x 4 = 28
Answer:
120 ways
Step-by-step explanation:
This can be solved through analytical combination.
First, select the president; this implies selecting one person out of five people, which is in 5 ways.
Secondly, select the vice president, this implies selecting one person out of four people, since one position has been taken by the president already leaving only four people which is in 4 ways
Thirdly, select the secretary, this implies selecting one person out of three remaining people, which is in 3 ways
Lastly, select the treasurer, this implies selecting one person out of two remaining people, which is in 2 ways
Therefore, ways by which a president, vice president, secretary, and treasurer can be elected is
5 x 4 x 3 x 2 = 120 ways
Answer:
No it's not!
Step-by-step explanation:
because the length (long) of J and K are totally different whereas the breadth(width) of J and K is also different which does make similar in sense
Answer: it will take 43.25 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 = $1000
A = $10450
r = 5.5% = 5.5/100 = 0.055
n = 2 because it was compounded 2 times in a year.
Therefore,.
10450 = 1000(1 + 0.055/2)^2 × t
10450/1000 = (1 + 0.0275)^2t
10.45 = (1.0275)^2t
Taking log of both sides, it becomes
Log 10.45 = 2t log 1.0275
1.019 = 2t × 0.01178 = 0.02356t
t = 1.019/0.02356
t = 43.25 years
