Find the 2 different rates at which the farm worker worked:

3 pints
--------- = 0.75 pint/min
4 min

2 pints
---------- = 0.67 pint/ min
3 min

Then you need to subtract 0.67 pint/min from 0.75 pint/min to answer this question.

Alternatively, subtract 2/3 pint/min from 3/4 pint/min.

<h2>Answer:</h2>

Luke does a work of 308Nm

<h2>Step-by-step explanation:</h2>

If we have a constant force \vec{F} that acts on a body in the same direction as the displacement \vec{s}, then the work W is defined as the product of the force magnitude F and the displacement magnitude s. In other words:

W=Fs, which is valid for a constant force in direction of straight-line displacement.

In this problem:

F=22N \\ \\ s=14m

Therefore:

W=22\times 14 \\ \\ \boxed{W=308Nm}

A woman passed gas silently. I said "it stinks", and she said "I apologize. Excuse me". Why did she say both of those things?

Find the radius of a circle with circumference of 45.84 meters. Use 3.14
alukav5142 [94]

Answer:

3.8 meters

Step-by-step explanation:

In order to find the circumference for a circle, we use the formula π(radius)²

The circumference give is 45.84 and the π given is 3.14

All we have to do is to just substitute them.

45.84 = 3.14(radius)²

45.84 / 3.14 = radius²

14.6 = radius²

radius = √14.6

radius = 3.82 ≅ 3.8
