Samuel buys 3 3/4 feet of lumber for a shelf. The lumber costs $ 2.25 per pound how much did Samuel pay?

1 answer:

3 0

Samuel pays $8.34
a way you can figure this out is:
3 times 4 plus 3 and your answer comes out to 15
then: 15 divided by 4 and that equals 3.75
now: 3.75 times $2.25

A city police force is made up of 24% females. If there are 72 females on the force, how many males are on the force?

erastovalidia [21]

Answer:

228 males

Step-by-step explanation:

Let x be the number of males.

This means x + 72 is the total number of people.

So $\frac{72}{x+72}$ is the fraction of females in the force.

Thus, we can form the equation:

$\frac{72}{x+72} = 0.24$

$x+72 = \frac{72}{0.24}$

$x = \frac{72}{0.24} -72$

$x = 228$

Thus, the answer is 228 males.
