Alika [10]

Explanation:

Generally, a small difference in blood pressure readings between arms isn't a health concern. However, a difference of more than 10 millimeters of mercury (mm Hg) for either your top number (systolic pressure) or bottom number (diastolic) may be a sign of blocked arteries in the arms, diabetes or other health problem

alexdok [17]

Answer:

d=3.79\ g/cm^3

Explanation:

Given that,

The mass of a sample, m = 16.7 grams

Volume of the sample, V = 4.4 cm³

We need to find the density of the metal sample.

Density = mass/volume

Substituting all the values,

d=\dfrac{16.7\ g}{4.4\ cm^3}\\\\=3.79\ g/cm^3

So, the density of the metal sample is 3.79\ g/cm^3.
