Hmmm lemme do the first one only
Answer:
31.8%
Step-by-step explanation:
The formula for simple interest is I = PRT, where I = interest earned/paid, P = principal amount deposited or borrowed, R = rate of interest as a decimal, and T = time in years.
I = PRT
5720 = (1200)(R)(15)
5720 = 18,000R
R = 0.3177777, rounded to 31.8%
Width= 8 cm
Because 192 / 2 = 96 / 12 = 8
SA= (perimeter * height) + 2 (length * width)
SA= (20*12)+2(2*8)
SA= 240+32
SA= 272 cm2
Step-by-step explanation:
principal = 18000
Time = 3 yrs
Rate. = 8%.
CI. = ?
Now
CI = p ( 1+ R÷ 100) ^T
CI = 18000( 1+ 8÷ 100 ) ^ 2
CI = 20995.2
Hope it's is Right :-)
