The speed of Maglev train is 267 miles per hour.
Step-by-step explanation:
Given,
Speed of Maglev train = 430 kilometers per hour
We know that;
1 kilometer = 0.62 miles
Therefore,
430 kilometers = 0.62*430
430 kilometers = 266.6 miles
Rounding off to nearest whole number
430 kilometers = 267 miles
The speed of Maglev train is 267 miles per hour.

Answer:
None of the answers are right
Step-by-step explanation:
Since a hexagon has 6 sides, and perimeter is the length of all the sides summed up, we can multiply 6 by 2x+y to find the perimeter.
6(2x+y)
Distribute the 6 to each term in the parentheses:
6(2x)+6(y)
12x+6y is the perimeter. None of the answers are right.
The answer is A because the square root function needs to be greater than or equal to zero bc the circle is filled and you can’t have a negative radical. It’s also choice A because the -1 is outside of the radical which means it’s being translated downwards from the parent function. Hope that helps ;-;
