Answer:
She made 640 free throw attempts.
Step-by-step explanation:
First, you use the information from the question to make the equation 128/x = 1/5.
Next, you cross multiply 128 by 100 and I got 12800.
And you continue to cross multiply 20 by x.
Now, the equation you should have is 20x = 12800
You divide 20 by 12800 and you get 640.
The equation of a circle:
(h, k) - center
r - radius
We have:
B) -0.4 seconds
Laps: 25
Goal: -10 seconds to all 25 laps combined (10 seconds difference => -10)
divide by total laps
-10 /25 = -0.4s difference each lap
45=9⋅5 , so 2√45 is the same as 2⋅√9⋅5 . The √9=3 , so a 3 can be removed. leaving 2⋅3√5 , or 6√5
