Answer:5 h 48 min
Step-by-step explanation:
t/8+t/12=1
=> 3t+2t =24
5t=24
t=24/5
t=5 and 4/5 h
That equal to 5 h and 8/10 h or 5h and 8*6 min
So the answer is 5 h 48 min

Step-by-step explanation:
Answer:
2.2
Step-by-step explanation:
To find a, you use a formula called the law of cosines:
The law of cosines tells us:
a^2 = b^2 + c^2 - 2bc cosA
So lets plug in the values:
a^2 = 4^2 + 3^2 -2(4)(3)cos(32)
a^2 = 25-24cos32
a^2 is roughly equal to 4.97
therefore a roughly equal to 2.2
I think you are asking if -8x ≥ 40, find x. What we do here is we divide negative 8 by both sides. This gives us x ≥ 5. BUT, we have to be careful!!!! When we divide an inequality on both sides by a negative number, we have to switch the sign. Thus, our answer is x ≤ 5.
