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

To round 0.472 to the nearest tenth consider the hundredths' value of 0.472, which is 7 and equal or more than 5. Therefore, the tenths value of 0.472 increases by 1 to 5.
So, the answer would be 0.5.

Answer:
Length: 25
Step-by-step explanation:
the ratio we use is 5:1
125÷5=25
5 is the width and 25 is the length
to check the answer find the area with those measurements
5x25=125 so its correct
The answer would be 129.85
53 x 1.45 = 76.85
76.85 + 53 = 129.85 dollars
