Answer:
<em>B) $1619.25</em>
Step-by-step explanation:
<em>Equation:
</em>
<em>A = P(1 + rt)
</em>
<em>
</em>
<em>Calculation:
</em>
<em>First, converting R percent to r a decimal
</em>
<em>r = R/100 = 9%/100 = 0.09 per year.
</em>
<em>
</em>
<em>Solving our equation:
</em>
<em>A = 1275(1 + (0.09 × 3)) = 1619.25 </em>
<em>A = $1,619.25
</em>
<em>
</em>
<em>The total amount accrued, principal plus interest, from simple interest on a principal of $1,275.00 at a rate of 9% per year for 3 years is $1,619.25.</em>
Hope this helps, have a good day. c;
The greatest common factor (GCF) of 21 and 84 is 21.
The GCF is the largest number by which both numbers can be divided. Between 21 and 84, it is 21 because 21/21=1 and 84/21=4.
7/10 8/11 please tell me if this is helpful, I know 7/10 is right but idk about 8/11
18. s = 5r^2 + 7......making r the subject
s - 7 = 5r^2
(s - 7) / 5 = r^2...by taking the sqrt of both sides, it eliminates the ^2
( sqrt (s-7)/5) = r
19. h = ut - 1/2gt^2....u = 100, t = 1 4/5(or 9/5)...g = 6.4
h = (100)(9/5) - 1/2(6.4)(9/5^2)
h = 180 - 1/2(6.4)(3.24)
h = 180 - 3.2(3.24)
h = 180 - 10.368
h = 169.632 or 169 79/125
20. sorry..do not know this one
