Answer:
Luis incurred 107 extra text messages.
Step-by-step explanation:
Giving the following information:
Luis's cell phone plan costs $39 per month. Text messages cost an additional $0.15 each.
<u>To calculate the number of text messages, we need to use the following formula:</u>
Total cost= 39 + 0.15x
x= number of text messages
55.05= 39 + 0.15x
16.05= 0.15x
107= x
Luis incurred 107 extra text messages.
question:
How many cubes with side lengths of \dfrac12 \text{ cm} 2 1 cmstart fraction, 1, divided by, 2, end fraction, start text, space, c, m, end text does it take to fill the prism?
Step-by-step explanation:
81 cubes are needed to fill the prism
Step-by-step explanation:
Volume of prism = 3 cubic units
Side lengths of cube = 1/3
Therefore the volume of the cube is,
V = a³ (a = side of the cube)
V = 1/3 × 1/3 × 1/3
= ( 1/3 )³
= 1/27 cubic units
To find the number of cubes needed to fill the prism, we need to divide the volume of cube by volume of the prism.
Number of cubes to fill the prism= Volume of prism / Volume of cube
= 3÷1/27
=3×27/1
= 81
Therefore, 81 cubes are needed to fill the prism
