i think its D, (change my mind)
Answer: From what you wrote the I think the ball is drop
At time 0 you are 7 meters above ground
You basically just need to solve for
1.5 =7t-4.9t^2
by rearrange the equation you get
4.9t^2-7t+1.5=0
by using Quadratic Formula
t=1.166s
Answer
668 + 232 ones = 900
or
668 + 23 tens + 2 ones = 900
or
668 + 2 hundreds + 32 ones = 900
or
668 + 2 hundreds + 3 tens + 2 ones.
<u>Explanations</u>
900 - 668 = 232. Meaning we can add 232 ones to 668 to get 900.
232-200 = 32 ⇒ Meaning, we can add 2 hundreds and 32 ones to 668 to get 900.
32-30 = 2. This means we can add 2 hundreds, 3 tens and 2 ones to 668 to get 900.
900 - 668 = 232
The answer for that question is Angle bisectors
