Answer:
0.5 %
Step-by-step explanation:
Annual rate = 6 %/yr
Monthly rate = ¹/₁₂ × 6 = 0.5 %/mo
If you invested $100 at 6 % annual simple interest, you would have <em>$106 </em>at the end of the year.
Simple interest is calculated only on the principal.
If the interest were calculated at 0.5 % monthly simple interest, you would get $0.50 at the end of each month. At the end of 12 mo, you would have <em>$106.
</em>
Answer:
Here are the steps to find the volume.
Step-by-step explanation:
- Volume = length x width x height.
- You only need to know one side to figure out the volume of a cube.
- The units of measure for volume are cubic units.
- Volume is in three-dimensions.
- You can multiply the sides in any order.
- Which side you call length, width, or height doesn't matter.
