you use the info given to find the volume of the cube

hint: V = s^3

jim_thompson5910 · Answer

s = side length of the cube

anonymous · Answer

3.375

jim_thompson5910 · Answer

now you'll multiply that by 3 since "Metal screws weigh 3 kilograms per cubic meter"

In a seminar, the ratio of the men to women is 5:9. If there are 56 people in the seminar, how many are women?

jim_thompson5910 · Answer

hints:

m = # of men
w = # of women

" the ratio of the men to women is 5:9" so 5/9 = m/w

there are 56 people total, so, m+w = 56. Solve for w to get w = 56-m

you can plug that into the first equation to get this new equation below

$$\Large \frac{5}{9} = \frac{m}{56-m}$$

anonymous · Answer

Dont get it

jim_thompson5910 · Answer

further hint:

cross multiply to get
$$\Large \frac{5}{9} = \frac{m}{56-m}$$
$$\Large 5(56-m) = 9m$$
and solve for m
