Answer:

10/9 cm³

Step-by-step explanation:

First, find volume of one block.

Side length = 1/3 cm (given)

Volume = (1/3)³

= 1/3 x 1/3 x 1/3

= 1/27 cm³

Total volume

= 1/27 x 15 x 2

= 1/27 x 30

= 30/27

= 10/9 cm³

There are 100 people in a sport centre.

We need to determinate who doesn't use anything, so first we must know the real number of who are practising: a person can do more things.

For doing this, is better use a three-circles graphic, but we try to do without it.

So

  • 16 pool + gym + track, and this number is sure
  • 38 gym + pool, but this number includes the people of 1st point. We must know who do only gym + pool: 38 - 16 = 22
  • 31 pool + track, this number also includes people of 1st point, so: only pool + track 31 - 16 = 15
  • 33 gym + track, this number also includes people of 1st point, so: only gym + track 33 - 16 = 17

now:

  • 67 gym, we must know who use only gym: 67 - 16 (gym + pool + track) - 22 (gym + pool) - 17 (gym + track) = 12
  • 62 pool, we must know who use only pool: 62 - 16 (gym + pool + track) - 22 (gym + pool) - 15 (pool + track) = 9
  • 56 track, we must know who use only track: 56 - 16 (gym + pool + track) - 15 (pool + track) - 17 (gym + track) = 8

now we must now who do some facility: let's sum all

16 + 22 + 15 + 17 + 12 + 9 + 8 = 99

99/100 practise something

So only 1/100 doesn't use nothing

The probability is 1%

A group of friends is going to a baseball game. A general admission ticket to the game costs $9.00. A ticket for a fan club memb
AnnyKZ [126]

Answer:

See explanation!

Step-by-step explanation:

The term 9x is comprised of two values: 9 and x. The 9 represents the cost of the general admission tickets. Since the expression is representing the total cost for the group of friends, the number of friends attending must be represented somehow in the equation. Since the $9 is paired with the x, this means that x represents how many of the friends are paying the general admission price. After interpreting both values within the term, the meaning of the term 9x is simply just the total cost of the friends that are paying the general admission price! Hope this helps!

A box contains 5 plain pencils and 7 pens. A second box contains 4 color pencils and 4
Savatey [412]
5:7 (pencils to pens)

7/12 chance that a pen from the first box will be selected.

4:4 (colour pencils to crayons)

4/8 = 1/2 chance that a crayon from the second box will be selected.

The probability of picking both:

7/12 * 1/2 = 8/24 = 1/3
