Answer:

  3 1/2 hours

Step-by-step explanation:

This is a problem in units conversion. We want to get from bags to hours by way of minutes per bag. One bag takes an effort of 2/3 person·minute, so we need to divide the total effort by the number of persons and convert minutes to hours.

  (1575 bags)×(2/3 person·min/bag)/(5 person)/(60 min/h)

  = (1575)(2/3)(1/5)(1/60) h = 3.5

It will take the 5 of them about 3 1/2 hours to prepare 1575 bags.

Pierre lifts a 60-kg crate onto a truck bed 1 m high in 3 s. Marie lifts twenty-four 2.5-kg boxes onto the same truck bed in a t
lys-0071 [83]

Answer:

Pierre operates at a greater power level than Marie.

Marie and Pierre do  the same amount of work

Step-by-step explanation:

Mass of crate=60kg

Height of truck bed=1 m

Time=3s

Pierre's work done=60\times 1\times 9.8=588J

Using formula Work done=mgh

Where m=mass of object

g=Acceleration due to gravity=9.8m/s^2

Power=\frac{w}{t}

Using the formula

Pierre's power=\frac{588}{3}=196watt

Mass of box=2.5Kg

Total number of boxes=24

Total mass of boxes=2.5\times 24=60kg

Time=2 min=2\times 60=120s

1 min=60 s

Marie;s work done=60\times 1\times 9.8=588J

Marie's power=\frac{588}{120}=4.9watt

Pierre operates at a greater power level than Marie.

Marie and Pierre do  the same amount of work

When 27x^2z/-3x^2z^6 is completely simplified, the exponent on the variable z is _____.
Savatey [412]
<span>The expression given (27x^2)z/(-3x^2)(z^6), can be simplify as below:

 By properties of powers, if you have the same base, you can substract the exponents. Then:

 =(</span>27x^2)z/(-3x^2)(z^6)
 =-9z/z^6  (As you can see: x^2-2= x^0=1)
 =-9/z^5    (Then, z^6-1=z^5)
<span>
 Therefore, the answer is: The exponent on the variable z is 5.</span>
