Answer:
X = -2
Step-by-step explanation:
X^3 + 8 = 0
X^3 = -8
X = -8 ^ (1/3)
X = -2
Answer:
6 hours 30 minutes
Step-by-step explanation:
morning work=3 hours 45 minutes
afternoon work=2 hours 45 minutes
total hours=?
Here,
3 hours 45 minutes+2 hours 45 minutes
=6 hours 30 minutes
Therefore,Terry Baelett worked 6hours 30 minutes a day.
Answer:
1 meter farther
Step-by-step explanation:
The difference in time from 4 seconds to 10 seconds is 6 seconds.
The speed is half of the difference of time.
That is why the speed is 3 m/s.
The difference in time from 10 to 18 is 8 seconds.
Take the time and divide it by 2 to get the speed.
The speed is 4 m/s.
The object's position is 1 more meter.
4 m/s - 3 m/s = 1 m/s
Assuming those lines are parallel, then this means the alternate interior angles are the same measure
3x-26 = 2x
3x-26+26 = 2x+26 ... adding 26 to both sides
3x = 2x+26
3x-2x = 2x+26-2x ... subtracting 2x from both sides
3x-2x = 26
<h3>x = 26 is the answer</h3>
Answer:
b. 45 N
Step-by-step explanation:
The sum of the forces exerted by the two miners = 25 + 20
= 45 N
Since after applying a force of 45 N by the two miners the cart remained stationary, it implies that a resistance force of at least 45 N acts against their push. Thus, the force exerted by the road could be equal to 45 N or greater than 45 N.
Probably, if the sum of the forces applied is 46 N, the cart would move. Which depends on the value of resistance force applied by the road. Thus, the appropriate answer from the given option is B.
Since the force applied on the cart equals the resistance force exerted by the road, the cart would not move.
