Step-by-step explanation:
Surface area = 2(12 × 8) + 2(12 × 3) + 2(3 × 8) = 312 in²
The Formula Of Volume Is :
V = L*W*H. So, Lets Plug In The Known Values.
V = 16*16*16.
16*16 = 256.
256 * 16 = 4096 yr^3. This Is The Volume. Any Further Questions?
Answer: $12000 was invested at 7% while $8000 was invested at 9%.
Step-by-step explanation:
Based on the information given in the question, let the amount that was invested at 7% be n.
Therefore,
0.07n + 0.09(20000 - n) = 1560
0.07n + 1800 - 0.09n = 1560
-0.02n = 1560 - 1800
-0.02n = -240
n = 240/0.02
n = 120
Therefore, $12000 was invested at 7% while $8000 was invested at 9%.
