Answer:

B:0.2(48)

Step-by-step explanation:

20 percent of 48 means 20 per hundred of 48 so the percentage is always divided by 100 before multiplying it by the value whose percentage you are trying to find. Knowing that then the calculation of finding 20 percent of 48 is done as follows:

20% of 48 = 20/100 * 48 = (20/100) * 48 = 0.2 * 48

There are 135 people in a sport centre. 73 people use the gym. 59 people use the swimming pool. 31 people use the track. 19 peop

Answer:

24 people

Step-by-step explanation:

((The numbers are up there, so I am not going to define each variable.))

For starters, there is no overlap between the double facilities groups, except the triple facility users, so:

19 + 9 + 16 - 4 = 40 people

Since there is overlap between single and double groups, you will need to subtract, so:

Gym: 73 - 19 - 16 = 38

Pool: 59 - 19 - 9 = 31

Track: 31 - 9 - 16 = 6

Total for 1 facility: 38 + 31 + 6 - 4 = 71 people

((Minus 4 because the 4 triple facility users overlap the double facility users (problem is in layers: layer 1 minus layer 2, then minus layer 3).))

Next, add the totals:

71 + 40 = 111 people (using facilities)

135 - 111 = 24 people (who didn't use any)

(((I'm not 100% sure on this answer, so if someone could check my work, that would be much appreciated.)))

The sum of a number times 8 and 21 is less than -16.

vodka [1.7K]

Hello.

First of all, let the number be t.

8 times t can be written like this:

$\mathrm{8t}$

Notice that the number is before the variable and the times sign (×) is not there.

We can write it as 8×t, but we usually write it as 8t.

The sum of means we add:

8t+21

Now, "less than" is "<" :

$\mathrm{8t+21 < -16}$

Therefore, the answer is

$\mathrm{8t+21 < -16}$

I hope it helps.

Have a nice day.
