Answer: 
Step-by-step explanation:
Given: Fraction of 7th graders got A = 
Fraction of 7th graders got B = 
The fraction of the students got an A or B = Fraction of 7th graders got + Fraction of 7th graders got B
Hence, the required fraction:
Answer:
A. 3 < t < 9
Step-by-step explanation:
When the particle is moving to the right, the velocity is positive.
To find the velocity, take the derivative of s(t) with respect to t.
s(t) = -t³/3 + 13t²/2 − 30t
s'(t) = -t² + 13t − 30
Find when the velocity is 0.
0 = -t² + 13t − 30
0 = t² − 13t + 30
0 = (t − 3) (t − 10)
t = 3, 10
Check the sign of s'(t) in each interval.
0 < t < 3, s'(t) < 0
3 < t < 9, s'(t) > 0
The particle moves to the right when 3 < t < 9.
To the nearest thousand, it is 8,000
To the nearest hundred, it is 7,900
To the nearest ten, it is 7,930
Answer:
540 in^3
Step-by-step explanation:
You do lwh.
10 * 18 * 3.
Answer:
a=-1/2b+c+-7/2
a= -1/2b+1/6c+-13/3
a= -1/2b+-1/2c-5
I really hope that my answer is right
