Hunter and his workout partner arelifting weights together, doing manysets of each exercise. On a certainexercise, Hunter is usi
Soloha48 [4]

9514 1404 393

Answer:

  • 1 set completed
  • 21 kg

Step-by-step explanation:

The difference in mass of the bars is 19-15 = 4 kg. The difference in mass of the added weight is 6-2 = 4 kg. The difference in total mass (bar +added) is reduced by the difference in added mass after each set. The number of sets required to reduce the difference to zero is ...

  (4 kg)/(4 kg/set) = 1 set

After 1 set, Hunter will increase the mass to 19 kg + 2 kg = 21 kg.

After 1 set, his partner will increase the mass to 15 kg +6 kg = 21 kg.

Both will be lifting 21 kg for their 2nd set, after they have completed 1 set.

_____

<em>Additional comment</em>

You can write equations for the mass being lifted by Hunter (h) and his partner (p) after s sets:

  h = 19 +2s

  p = 15 +6s

The masses will be equal when ...

  h = p

  19 +2s = 15 +6s

  19 = 15 +4s . . . . . . . subtract 2s

  4 = 4s . . . . . . . . . . . subtract 15

Note that the number on the left side of the equation is 19-15, the difference of bar masses. The coefficient on the right side is 6-2, the difference in the added masses. To find the number of sets (s), we divide the equation by the coefficient of s:

  4/4 = s = 1

In the above solution we skipped directly to this final division in order to find the number of sets until the lifted masses were equal.

Select the correct answer. The supply and demand curves for a product line of bicycles are shown. Approximately where is the equ
Dmitry_Shevchenko [17]

Answer:

B. (132,220)

Step-by-step explanation:

The equilibrium point is the point where the quantity demanded is equal to the quantity supplied.

The equilibrium point (equilibrium price and equilibrium quantity) occur at the point where the supply and demand curves cross each other.

From the graph, we can see that the supply and demand curve cross each other at point. The equilibrium point is this point and it is gotten by tracing to the vertical and horizontal axis.

The equilibrium point is at (132, 220).

Hence the equilibrium price = $132 and equilibrium quantity = 220

Stepping off a distance by counting your paces is generally a more precise method of measuring than using a measuring tape.
dimulka [17.4K]

Answer:

False

Step-by-step explanation:

It depends on the distance and the curvature of the path. It is a straight line between endpoints and the length is a reasonable multiple of the full length of the tape measure then the tape measure is more accurate.  If on the other hand the terrain is rugged and/or curvy then there isn't much to choose between the two. I think you are intended to answer false. The question leaves a lot to be desired.
