Answer:

Total people in survey = 10000

Number of people who like folk song only = 3000

Step-by-step explanation:

0% like none, thus 90% like atleast anyone of them.

Let the total number of people in survey be x.

90x/100 = 70x/100 + 60x/100 - 4000

40x/100 = 4000

x = 400000/40

x = 10000

Total number if people who like folk songs = 70*10000/100

= 7000

Number of people who like folk song only = 7000 - 4000

= 3000

What does communitive property mean
madreJ [45]
What you meant was the "commutative" property.

So we can say that when adding:

<em>"<u>Commutative</u> means that the order does not make any difference in the result."</em>

Example:

5 + 6 = 6 + 5

a + b = b + a

The commutative property does not hold for subtraction.

Example:

4 - 1 ≠ 1 - 4

a - b ≠ b - a

Ok, now does the commutative property hold true for multiplication?

2 x 3 = 3 x 2

2 x 3 x 4 = 4 x 3 x 2

Yes.

What about division?

12 ÷ 4 ≠ 4 ÷ 12

The commutative property does not hold for division.

Please do 81 cookies and distributed 44
AveGali [126]
I’m not quite sure what the question is, but 81 cookies distributed among 44 people would mean that each person gets 0.02 cookies each.

Marta has 8 yellow ribbons what are 2 different ways she can place the ribbons on her door or wall write two different addition
Drupady [299]
One way she can place the ribbons is to place them in groups of 8/2=4, making 4+4=8 ribbons (2 groups because 8/4=2). Next, she can put them in groups of 2 (we can make it out of only 2 if we want since 2 is a factor) to get 8/2=4 groups of 2 and 2+2+2+2=8
