Answer:
10 x 10 x 10 x 10
Step-by-step explanation:
10^4 is equivalent to 10 x 10 x 10 x 10
50,000 + 100,000 = 150,000
Divide 150,000/2 and it equals 75,000
T is equal in both situations ... d = r X t so d/r = t
c is rate of waters current

14(12 - c) = 7(12 + c)
2(12 - c) = 12 + c
24 - 2c = 12 + c
12 = 3c
4 = c The rate of the waters current is 4 miles per hour.
Reflectional symmetry<span> exists when the figure can be folded over onto itself along a line. This line is called the "line of symmetry". The correct answers for this would be.
</span>-A line of symmetry will connect a vertex and a midpoint of an opposite side
-it has 7-fold symmetry.
