Answer:
<h2>Wedge Z requires the least amount of force to do a job.</h2>
Step-by-step explanation:
In physics, Work is defined as the energy needed to move certaing object through a certain distance. Specifically, the work done is directly proportional to the force exerted and the distance.
It's important to know that a change of point is needed to have actually work done, physically speaking. This means if the object doesn't move, then there's no work done.
Mathematically, the work is defined
Isolating the force
So, notice that the distance is inversely proportional to the force needed, which means the less distance, more force we need.
Now, the problem is giving wides and slopes, which we can use to find heights. And we know already that the less distance we have, the greater force we need, or the most distance, the least force.
Let's find which wedge has the greatest vertical distance.
<h3>Wedge 1.</h3>
<h3>Wedge 2.</h3>
<h3>Wedge 3.</h3>
<h3>Wedge 4.</h3>
Notice that the last wedge has greater vertical distance, that means Wedge Z requires least amount of force to do a job.
22,000 to 19,000
22,000 - 19,000 / 22,000 x 100
3,000/22,000 x 100
0.136363636363636 x 100
13.63636363636364%
13.64%
14%
Answer: 2.87 hours
Step-by-step explanation:
There may be a typo in the question because 55 hours in a day is not logical so you must have meant 5.5 hours.
In that case, the hours he will require on the third day would require the distance left to calculate. Get this distance from the first 2 days.
Day 1 distance travelled = Time * Speed
= 5.5 * 66
= 363 miles
Day 2 distance travelled = Time * Speed
= 5.5 * 58
= 319 miles
Total distance remaining
:= 840 - 363 - 319
= 158 miles
Travelling at 55 miles per hour, the time to be taken is:
= Distance remaining / Speed
= 158 / 55
= 2.87 miles per hour
Answer:
Just guessing here but would the bottom be 4,8,12,16,20 maybe since it is going by 4 then you do the same for the top since it is going by 3
Step-by-step explanation:
The answer is D. Because the sq. rt. of 1 is 1, the sq. rt. of 9 is 3, and the sq. rt. of 25 is 5. When you take the sq. rt. of 50 you get 7.071067.
