In a game for 24 groups, the average number of children was 16. When one more group of children was formed to join in the game, the average number of children became 18. The number of boys to girls who had just joined in the game was in the ratio 5:6. If there were 220 boys at first, how many more boys than girls were in the end?

Answers

Answer:

50 boys

Step-by-step explanation:

The number of groups = 24

The average number of children = 16

The new average number of children when one group is added = 18

The ratio of boys to girls in the group that just joined = 5:6

The initial number of boys = 220

Let the initial number of children

The initial total number of children = 24 × 16 = 384

The initial number of girls = 384 - 220 = 164

The final number of children = 25 × 18 = 450

The number of children in the group that joined in the game = 450 - 384 = 66

The ratio of boys to girls in the group = 5:6

Therefore, we get;

The number of boys = 66 × 5/11 = 30

The number of girls = 66 - 30 = 36

The number of boys at the end = 220 + 30 = 250

The number of girls at the end = 164 + 36 = 200

The number of more boys than girls at the end = 250 - 200 = 50

The number of more boys than girls at the end = 50 boys

Identify whether each value of x is a discontinuity of the function by typing asymptote, hole, or neither. 5x/ x3 + 5x2 + 6x

Answers

Answer:

Function is discontinuous at

x=0   (Hole)

x=-3  (Vertical asymptote)

x=-2  (Vertical asymptote)

Step-by-step explanation:

Given: f(x)=(5x)/(x^3+5x^2+6x)

We need to identity the discontinuity of the function. As we know function is discontinuous where it is not defined.

So, The function is discontinuous at hole, asymptote and break point.

f(x)=(5x)/(x^3+5x^2+6x)

f(x)=(5x)/(x(x^2+5x+6))

f(x)=(5x)/(x(x+3)(x+2))

For hole, we will cancel like factor from numerator and denominator.

At x=0 we get hole.

For vertical asymptote, we set denominator to 0

x+3=0  and   x+2=0

Vertical asymptote:

x=-3 and x=-2

Function is discontinuous at

x=0   (Hole)

x=-3  (Vertical asymptote)

x=-2  (Vertical asymptote)

Answer:

asymptote

asymptote

hole

What property does the statement show? ( 4 x 8 ) x 3 = ( 4 x 4 ) x 3

Answers

Answer: Associative property of multiplication.

Step-by-step explanation:

The property demonstrated by the statement "(4 x 8) x 3 = (4 x 4) x 3" is the associative property of multiplication.

The associative property of multiplication states that you can change the grouping of numbers in a multiplication expression without changing the result. In this case, both sides of the equation involve multiplication, and the numbers being multiplied are grouped differently but still yield the same result.
commutative property of multiplication

Caroline bought 20 shares of stock at 101/2, and after 10 months the value of the stocks was 111/4. If Caroline were to sell all her shares of this stock, how much profit would she make? A. $15 B. $10 C. $225 D. $210

Answers

Answer:

 Option A is correct that is $15.

Step-by-step explanation:

Caroline bought 20 shares of stock at 10(1)/(2)=(21)/(2), and after 10 months the value of the stocks was 11(1)/(4)=(45)/(4).

We need to calculate the profit which is the difference of the two values of the stock.

(45)/(4)-(21)/(2)

(3)/(4)

The above value is for 1 share we have to calculate it for 20 shares

So, we will multiply it with 20 we get:

(3)/(4)\cdot 20=15

Therefore, Option A is correct that is $15.
First,
101.2=10.50
111/4=11.25
Second, we minus our old by the new.
11.25-10.50=0.75
Then, we times the by stock;answer is below.
0.75 * 20 = 15
