11-8=3 where as 2+1=3
I did something like this before but there are other teaching methods that his teacher might be using so I apologize if I am incorrect. :)
A: She Has 0
E: she had 2 she ate one and gave one away
2 - 1 =1
1 - 1 = 0
Answer:
11/3 as a mixed number would be 3 2/3
Step-by-step explanation:
<span>H(t) = −16t^2 + vt + s
</span>
<span>H(t) = −16t^2 + 100t + 140
H(t) = 0 = </span><span>−16t^2 + 100t + 140
16t^2 - 100t -140 = 0
t = [100 +/- √ (100^2 -4(16)(-140) ) ] /(2(16))
t = 7.43 and t = - 1.18.
El que tiene sentido para la pregunta es t = 7.43 s.
Option B) 7 s (approximately)
