A scale has a percent error of 7%. The scale reads the mass of a book as 450g. Which statement describes what the actual mass of

ozzi

Answer:

The actual mass of the book is between 481 . 5 g and 418 . 5 g.

Step-by-step explanation:

The mass of the book on the scale = 450 g

The percentage error in the scale = 7%

So, the actual mass of the book is 450 g ± 7%

Now, 7 % of the mass 450 g = $\frac{7}{100} \times 450 = 31.5$

⇒ 7% of 450 g = 31.5 g

Now, the Actual mass of the book = 450 g ± 31.5 g

450 g + 31.5 g = 481 . 5 g

450 g - 31.5 g = 418 . 5 g

Hence the actual mass of the book is between 481 . 5 g and 418 . 5 g.

PLEASE HELP ME!

Troyanec [42]

If 450 is 1/4 of the amount that Henry has, you can find Henry’s amount by multiplying 450 • 4 which gives you an answer of 1800

Or, if you’re looking for a more complicated way, which I doubt, you can set up the problem as:

1/4x=450 and solve by dividing 450 by 1/4
