A 50 foot rope weighing a total of 32 lbs extended over a cliff that is 35 feet to the ground. A large 8 pound bucket with 19 ga
larisa86 [58]

Answer:

A function that gives the work required in foot-lbs to lift the bucket up x feet from the ground is W=16(50-x)+(19-\frac{x}{5})(8.3)x and  the work to get the bucket to the top of the cliff is 3726 foot-lbs

Step-by-step explanation:

Work done to lift the rope by distance x feet:

W_1=32(\frac{50-x}{2})

Work done to lift the bucket by distance x feet:

W_2=(19-\frac{x}{5})(8.3)x

On reaching top 7 gallons of water spilled out so , on going up by x feet \frac{7x}{35}=\frac{x}{5} gallons of water spilled out.

a function that gives the work required in foot-lbs to lift the bucket up x feet from the ground:

W=16(50-x)+(19-\frac{x}{5})(8.3)x

Now the work to get the bucket to the top of the cliff i.e. x =35

W=16(50-35)+(19-\frac{35}{5})(8.3)(35)

W=3726

Hence, a function that gives the work required in foot-lbs to lift the bucket up x feet from the ground is W=16(50-x)+(19-\frac{x}{5})(8.3)x and  the work to get the bucket to the top of the cliff is 3726 foot-lbs

What is the answer to 2/3 of something equals 10
denis23 [38]
In math, when you see the word "of" it usually means "times".

So the question is:

        <u>2/3 times something = 10</u>

Multiply each side of the equation by 3 :

             2 times something = 30

Divide each side by 2 :

                        <em>  something = 15</em>

Landon is driving at a constant speed of 55 miles per hour. At hat rate, how long will it take him to drive 275 miles?
Elza [17]

Answer:

5hours

Step-by-step explanation:

At constant speed, distance speed= distance/time taken

therefore, time will be obtained by the division of distance traveled by the speed.  

in this question the distance is provided but time is not hence time is calculated as follows. time= distance/time taken

                            =275miles/55miles/hour

                            = 5hours

I’m kinda stuck on here on how to do this .... how am I suppose to go down again if it’s not gonna be on the line.
mars1129 [50]

To graph the new shape, you must move each vertex down 3 units. This causes Q to become (1, 0), L to become (5, -2), and Q to become (1, 0). These values can be found by simply counting down by three for each point.
