omar lays down straight tracks for his model railroad. each length of track is 8 inches long. which of the following could be the total length of omar's track?
How many tracks does he lay down? What are your choices?
96 inches
82 inches bbzhnchn 74 inches 68 inches
To find the total length of Omar's track, we need to determine if any combination of track lengths could lead to the given total lengths.
Let's consider the options given. Since each length of track is 8 inches long, we can divide the total length by 8 and check if the result is a whole number. If it is, then it could be the total length of Omar's track.
Let's go through each option:
a) 204 inches:
- Divide 204 by 8: 204 ÷ 8 = 25.5
- Since 25.5 is not a whole number, this option is not possible.
b) 159 inches:
- Divide 159 by 8: 159 ÷ 8 = 19.875
- Since 19.875 is not a whole number, this option is not possible.
c) 288 inches:
- Divide 288 by 8: 288 ÷ 8 = 36
- Since 36 is a whole number, this option is possible.
d) 234 inches:
- Divide 234 by 8: 234 ÷ 8 = 29.25
- Since 29.25 is not a whole number, this option is not possible.
Therefore, the only possible total length for Omar's track is 288 inches, which is option c).
