Answer: 6 1/8
Step-by-step explanation:
1/8 x 2 = 1/8 x 2/1 = 2/8 = 1/4
1/4 x 3 = 1/4 x 3/1 = 3/4
3/8 x 4 = 3/8 x 4/1 = 12/8 = 1 4/8 = 1 1/2
1/2 x 3 = 1/2 x 3/1 = 3/2 = 1 1/2
5/8 x 1 = 5/8 x 1/1 = 5/8
3/4 x 2 = 3/4 x 2/1 = 6/4 = 1 2/4 = 1 1/2
Start with the big number first.
1 1/2 = 1 4/8
1 1/2 = 1 4/8
1 1/2 = 1 4/8
5/8 = 5/8
3/4 = 6/8
1/4 = 2/8
Add them all up.
1 4/8 + 1 4/8 = 2 8/8 = 3
3 + 1 4/8 = 4 4/8
4 4/8 + 5/8 = 4 9/8 = 5 1/8
5 1/8 + 6/8 = 5 7/8
5 7/8 + 2/8 = 5 9/8 = 6 1/8
The difference of the distances traveled by the comets for any given number of minutes is 25t.
Since the first comet travels at a speed of 30,000 miles per hour, the distance it travels in t minutes is d = 30000 mph × 1 h/60 min × t = 500t miles.
Also, the second comet travels at a speed of 28,500 miles per hour, the distance it travels in t minutes is d' = 28,500 mph × 1 h/60 min × t = 475t miles.
So, the difference in the distances traveled by the comets D = d - d'
= 500t - 475t
= 25t
So, the difference of the distances traveled by the comets for any given number of minutes is 25t.

Answer:
231.00
Step-by-step explanation:
Carol earns 16 for 30 minutes, so $32 an hour, 32 * 3 = 96.
Peter earns 15 every 20 minutes, so 20 * 3 = 60 minutes, and 15 * 3 = 45,
so he earns 45 dollars an hour. 45 * 3 = 135
135+96 = 231.00

Answer:
The given relation is not a function
Step-by-step explanation:
- The relation becomes a function if every x-value has only one y-value
- A function is a relation in which each input (x) has only one output (y)
<em>To test the graph is a function or not, draw a vertical line intersects the graph in different positions, if the line cuts the graph in just one point in all positions, then the graph represents a function.</em>
<em />
From the given figure
∵ The endpoint of the diameter of the semi-circle are (0, -2), (0, 2)
→ The x-coordinate = 0 has two values of y = -2, 2
∴ At x = 0, y = -2 and 2
∴ Not every x has only one y
∴ The given relation is not a function
<em>If you draw a vertical line intersects the semi-circle in different positions, it will intersect the semi-circle in 2 points, So the graph does not represent a function </em>
