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.
Answer:
C
Step-by-step explanation:
Convert the fractions into decimals. -2/3 = - 0.7 approximately.
-3/4 = -0.75.
So you have -0.75, -0.7, 0, and 0.7.
Put the negatives first because they have the least value. -0.75 is more negative than -0.7, so it would go first (remember it is really -3/4) , then the next negative -0.7 (-2/3) Zero is neutral so it goes next. Followed by the positive 0.7, which is the greatest.
hope this makes sense and helps. :)
The sales person receives a $200 sales commission. To get the answer, you would convert the percentage to a decimal, in this case... 2.5%, would become 0.025. You would then multiply 0.025•8000 to get your answer of $200. Which means in total, the salesperson would receive $8200.
Answer:
Step-by-step explanation:
You need to make the conversion from miles to feet. Since:
You get:
Convert 22 minutes to hours.
Since:
You get:
Therefore, the time in hours is:
Now you must use the following formula:
Where "V" is the speed, "d" is distance and "t" is time.
You can identify that, in this case:
Therefore, substituting values into the formula, you get:
