Answer: but make me brainliest and hope this helps
Step-by-step explanation:
All you have to do is add 25 to 15.
25+15=40
So, the time he arrives at work is at 7:40 AM.
A vector is basically an arrow that tells you where to go. Specifically it tells you a direction and how far. The direction component is the angle. The "how far" component is the magnitude or modulus or length of the vector.
For choice C in the upper right hand corner, we see that the vector 'a' starts off on the right side and points directly to the left. It's a horizontal vector. The arrow is at the left side. After going from tail to tip along vector 'a', we repeat the same motions for vector b. Think of it as following directions on a map. To take a shortcut, we follow the resultant vector r. This takes us from the tail of vector 'a' to the tip of vector b without any obstacles or deviations. So this is why choice C is the answer.
Note: if you use the parallelogram law for choice A, then the resultant vector will be the same as shown in choice C. This is of course assuming that each vector 'a' is the same length and direction between the two answer choices. The same assumption is for the b vector as well. Choice D is close to what choice C is saying, but the arrow for r is pointed the wrong way. The arrow head must be pointed at the tip of vector b which is the final destination we want.
Answer:
96 minutes or 1 3/5 hours
Step-by-step explanation:
To get this answer properly , we shall be converting any of the time fraction to minutes
The total time taken is 3 4/5 hours
1 hour is 60 minutes, 3 hours is 3 * 60 = 180 minutes
4/5 hours is 4/5 * 60 = 48 minutes
Total travel time is 48 + 180 = 228 minutes
Walking, he did for 2/5 hours = 2/5 * 60 = 24 minutes
Riding on a train took 1 4/5 hours; that would be 60 minutes plus 4/5 * 60 = 48 minutes ; a total time of 108 minutes
Time spent on walking and on train would be 108 minutes + 24 minutes = 132 minutes
The time spent on train would thus be 228 - 132 = 96 minutes = 60 + 36 minutes = 1 hour + 36/60 = 1 hour + 3/5 hours = 1 3/5 hours was spent on the train
Answer/Step-by-step explanation:
16. 4(x + 3) - 5 < 5x + 7
4x + 12 - 5 < 5x + 7
4x + 7 < 5x + 7
Collect like terms
4x - 5x < 7 - 7
-x < 0
Divide both sides by -1
x > 0
17. 24 > -3x
Divide both sides by -3
24/-3 < -3x/-3
-8 < x
x > -8
18. -5(2x - 6) + 3x < 2(2x + 1) - 11x
-10x + 30 + 3x < 4x + 2 - 11x
Add like terms
-7x + 30 < -7x + 2
-7x + 7x < -30 + 2
0 < -28
