The ideal weight of a nickel is 0.176 ounce. To check that there are 40 nickels in a roll, a bank weighs the roll and allows for an error of 0.015 ounce in total weight

Respuesta :

Answer:  Total weight will be 7.055 ounces.

Step-by-step explanation:

Since we have given that

Ideal weight of a nickel = 0.176 ounce

Number of nickels in a roll = 40

Total weight becomes

[tex]40\times 0.176\\\\=7.04\ ounces[/tex]

Error that was allowed in total weight = 0.015 ounce

So, Total weight will be

[tex]Total\ weight=7.04+0.015\\\\=7.055\ ounce[/tex]

Hence, Total weight will be 7.055 ounces.
