An iron ball has a density of 4 g/cm3.
navik [9.2K]
<h3>Answer:  60 grams</h3>

========================================================

Explanation:

m = mass

v = volume

d = density

The formula we use is

d = m/v

Multiplying both sides by v allows us to solve for m

d = m/v

d*v = m

m = d*v

Now plug in the given density (d = 4) and the given volume (v = 15) and simplify:

m = d*v

m = 4*15

m = 60 grams

Note how,

d = m/v

d = 60/15

d = 4

which helps confirm our answer

3 4/7 minus 2 1/5 by rounding to the nearest half
mylen [45]

Answer:

1 \frac{13}{35}

Step-by-step explanation:

3 \frac{4}{7} -  2 \frac{1}{5}

you can solve for the fractions first, but you have to give them a common denominator

\frac{20}{35}- \frac{7}{35}

= \frac{13}{35} which is in simplest form

then solve for the whole numbers

3-2=1

therefore, the answer is 1 \frac{13}{35}
