The ratio of women to men working for a company is 5 to 7. If there are 140 men working for the company, what is the total numbe

Thepotemich [5.8K]

So women:men=5:7
for every 5 units of women, there are 7 units of men so
there are 140 men and that equals 7 units so
140=7 units
solve for 1 unit
140/7=20
1 unit=20
women=5 units
5 times 20=100
women=100
total=women+men=100+140=240
another way would be to add up the units (5+7=12) and multiply by the amount per 1 unit

What is the volume of a rock if it has a density of 1.25g/ml if it has a mass of 7525g?

Rama09 [41]

Answer:

$\boxed{\tt v= 6,020 \ mL}$

Step-by-step explanation:

The density formula is

$d=\frac{m}{v}$

Rearrange the formula for v. Multiply both sides of the formula by v, then divide both sides by d.

$d*v=\frac{m}{v}*v$

$d*v=m$

$\frac{dv}{d}=\frac{m}{d}$

$v=\frac{m}{d}$

The volume can be found by dividing the mass by the density. The mass is 7525 grams and the density is 1.25 grams per milliliter.

$m= 7525 \ g\\d=1.25 \ g/mL$

$v=\frac{m}{d}$

$v=\frac{7525\ g}{1.25\ g/mL}$

Divide. Note that the grams, or "g" will cancel each other out.

$v=\frac{7525 \ }{1.25\ mL}$

$v=6020 \ mL$

The volume of the rock is 6,020 milliliters.
