How many pages can Jorge print in 3/5 of an hour if he can print 24 pages every 15 minutes?

MariettaO [177]

Answer:

57.6 pages

Step-by-step explanation:

First, you need to identify how many minutes are in 3/5 of an hour:

1 hour = 60 minutes

3/5 of an hour = 3/5 of 60 minutes

= 3/5(60)

= 36

So, you need to find out how many pages can be printed in 36 minutes. To figure this out, a ratio can be used:

15 : 24

36 : p

p represents pages in 36 minutes.

Now, you need to solve the ratio by figuring out what you need to multiply 15 by to get 36 and then multiplying that by 24:

15 * 36/15 = 36

36/15 = 2.4

24*2.4

= 57.6 pages

Katherine has 32 pop songs in 72 rock songs on her MP3 player that she will be organizing into paulista. Que want to por an eria

LUCKY_DIMON [66]

Answer: The greatest number of playlist Katherine can make =8

Each of playlist will have 4 pop songs and 9 rock songs.

Step-by-step explanation:

Given: The number of pop songs Katherine has= 32

The number of rock songs Katherine has= 72

If she want to make playlist such that in each playlist there is equal number of pop and rock songs, we need to find the GCF(greatest common factor) of 32 and 72.

We know that $32=2\times2\times2\times2\times2\\72=2\times2\times2\times3\times3$

We can see the GCF(32,72)= $2\times2\times2=8$

Hence, the greatest number of playlist Katherine can make =8

The number of pop songs= $\frac{32}{8}=4$

the number of rock songs= $\frac{72}{8}=9$

Each of playlist will have 4 pop songs and 9 rock songs.
