the answer to 54,000 x 10 is 540,000
Answer:
It was 4 years.
Step-by-step explanation:
To solve this problem we need to use the appropriate formula for simple interest, which is shown below:
M = C*r*t
Where M is the amount of interest, C is the initial amount of money, r is the rate of interest and t is the time elapsed in years. Applying the data from the problem we have:
840 =7000*0.03*t
840 = 210*t
210*t = 840
t = 840/210
t = 4
It was 4 years.
Answer:

Step-by-step explanation:
General arithmetic sequence formula: 
where
= first term, and d = common difference.
The first term is -8
And the common difference appears to be - 7 as 7 is subtracted to get to the next term. Ex. -8 - 7 = -15, -15 - 7 = - 22 and so on.
To get the explicit formula of the sequence we simply plug in the values of a1 and d the general arithmetic sequence formula
General formula: 
We have
and d = -7
So the formula to find the nth term would be

Answer:
Width = 9
Length = 13
Step-by-step explanation:
width = w
length = L
w(2) - 5 = L
w + w + L + L = 44
44 + 5 + 5 = 54
54/6 = 9
9(2) = 18 - 5 = 13
w = 9
l = 13
Check:
9 + 9 + 13 + 13 = 44
9(2) = 18 - 5 = 13
