The rule associated with moving decimal places, and multiplying by a value or multiple of 10, would be the following :
If you divide a value by 10 or a multiple of 10, you would move the decimal place to the left number of times as there are zeros in the multiple.
(Assuming that there are no zeros in the numerator value)
If you multiply by 10 multiple, then you would move the decimal to the right that many times as there are 0's in the value.
The solution would be that the decimal number is multiplied by 100.
I believe the answer is 6
Question thirteen is a right angle (because if you plot the pints, it obviously looks like a fit angle)
Question fourteen is c ( because when you plot all the points, the first two options don't make sense if side pq is congruent to qr, then we are left with options c and d. Option d forms a right triangle (and sides pq and qr can't be congruent) . Whereas in option c, it is mathematically possible for pq and qr to be congruent to one another)
Basically, all you have to do is plot the points for both questions and the answer will become obvious)
Answer:
The principal investment required to get a total amount, principal plus interest, of $400.00 from simple interest at a rate of 8% per year for 9 years is $232.56.
Step-by-step explanation:
Given
- Total accrued Amount A = 400.00 (Let say $)
- Interest rate r = 8% = 0.08
To determine
Principle P = ?
Using the formula
P = A / (1 + rt)
substituting A = 400.00, t = 9 and r = 0.08 in the formula
P = 400 / ( 1 + (0.08 × 9))
P = $232.56
Therefore, the principal investment required to get a total amount, principal plus interest, of $400.00 from simple interest at a rate of 8% per year for 9 years is $232.56.
Answer:
5x+40
Step-by-step explanation:
You would distribute 5 to x+8 and that would add up to 5x+40.
