Answer:
Kathy would take 7.56 seconds to run each of the 8-time segments of the 400-meter dash.
Step-by-step explanation:
Kathy ran the 400-meter dash in 60.48 seconds, so if she now divided that time into 8 equal time segments we have:

By dividing the above equation into 8:

Hence, she would take 7.56 seconds to run each of the 8-time segments of the 400-meter dash.
I hope it helps you!
Answer:
angle(2) = 118 degree
angle(3) = 118 degree
angle(4) = 62 degree
Step-by-step explanation:
To find angle 2 :

The rule (head to head):
angle(2) = angle(3) = 118 degree
And the last one is angle(4) which is the same thing:
angle(4) = angle(1) = 62 degree
I'm not this high in maths but I think it's -10 I don't know but I worked it out
Answer:
14
Step-by-step explanation:
multiply 3×2/3 and 3×4 and add them
2+12=14
The given expression is

We can write it in radical form, and the denominator of the exponent became the power of the radical. That is
![x^{9/7} = \sqrt[7]{x^9}](https://tex.z-dn.net/?f=x%5E%7B9%2F7%7D%20%3D%20%5Csqrt%5B7%5D%7Bx%5E9%7D)
And
![\sqrt[7]{x^9} = \sqrt[7]{x^7*x^2}](https://tex.z-dn.net/?f=%5Csqrt%5B7%5D%7Bx%5E9%7D%20%3D%20%5Csqrt%5B7%5D%7Bx%5E7%2Ax%5E2%7D)
We can also write it as
![\sqrt[7]{x^7}*\sqrt[7]{x^2} = x \sqrt[7]{x^2}](https://tex.z-dn.net/?f=%5Csqrt%5B7%5D%7Bx%5E7%7D%2A%5Csqrt%5B7%5D%7Bx%5E2%7D%20%3D%20x%20%5Csqrt%5B7%5D%7Bx%5E2%7D)
And that's the simplified form of the given exponential form .
