I believe it is the final choice because it correctly compares 2 sets of corresponding sides.
The equation of a circumference is 2

r. Since we know that r=17, we plug that into the formula, and get an answer of C. 34
If there are 45 beads, with a ratio of

Then,

Then if

Then

Therefore,

Meaning, there would be a ratio of 36 beads to 9 beads
The ball hits the ground when the height h(t) = 0 , so
-16t^2 + 80t = 0
-16t(t - 5) = 0
t- 5 = 0 or -16t^2 = 0 ( here t = 0 which corresponds to when ball is thrown)
t - 5 = 0 gives:-
t = 5 seconds (answer)
Answer:
Step-by-step explanation:
If they can be rounded to 70 to the nearest 10s. Then they are from 65 to 74.
Their sum is 136.
If we use 136 divided by 2 we get 68.
Since they're distinct, so one can be 67 and one can be 69
