The radius of Earth is about 3,980 miles. What expression can be used to find the approximate diameter of Earth?

1 answer:

3 0

To find the diameter, you use the formula: 2x. we use 2x because the radius is 2 times the diameter.

so, if the radius is 3,980, then we substitute that into the formula.

2(3,980)

this will give us 7960. the diameter is 7960 miles.

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.
