HELP

If there are 22 students (11 boys and 11 girls) in Ms. Cathies math classes and she chooses a student to answer a question at random. What are the chances she will pick you?

Answer:

A. 4/12, C. 1/3

Step-by-step explanation:

2/6 can be divided by 3. Therefore, the fraction is 1/3.

A. 4/12 can be divided by 4. This means the fraction will be 1/3. Because 1/3 is equal to 1/3, this option is correct.

B. 1/2 cannot be simplified. Because 1/3 is not equal to 1/2, this option is not correct.

C. 1/3 cannot be simplified. Because 1/3 is equal to 1/3, this option is correct.

D. 3/8 cannot be simplified. Because 3/8 is not equal to 1/3, this option is not correct.

Answer:

Number of bottles= 1,708

Step-by-step explanation:

Giving the following information:

Total liters= 35,874 litres

Bottle capacity= 21 liters

To calculate the number of bottles that can be filled given the actual capacity, we need to use the following formula:

Number of bottles= total liters / cottle capacity

Number of bottles= 35,874 / 21

Number of bottles= 1,708

Answer:

95 ; 105

Step-by-step explanation:

Let :

Aanya's time = x

Krish's time = x + 10

Together = 50

Hence

Aanya's rate = 1/x

Krish's rate = 1/(x + 10)

Together rate = 1/50

Hence,

1/x + 1/(x + 10) = 1 / 50

((x + 10) + x) / x(x + 10) = 1/ 50

(2x + 10)/ x² + 10x = 1/50

50(2x + 10) = x² + 10x

100x + 500 = x² + 10x

x² + 10x - 100x - 500 = 0

x² - 90x - 500 = 0

Using the quadratic equation solver :

x = 95.24 ; x = - 5.24

Time can't be negative

Hence, x = 95 (nearest minute)

It takes Aanya 95 minutes Alone a ND

Krishna (95 + 10) = 105 minutes alone

Answer:

Where's the triangle? Do you have an image?

The total number of games a girl play against a boy is 25, the number of games a girl plays against a boy is 10, the fraction of the games are boy-versus-boy is 2/9, and 1/5 fraction of all games at the tournament Anita plays the game.

We have given that,

Of the 10 kids in a chess club, 5 are left-handed and 5 are right-handed.

A permutation can be defined as the number of ways a set can be arranged, order matters but in combination, the order does not matter.

We have 5 girls and 5 boys in a chess club:

There are a total of 5×5 games girls play against a boy.

= 5×5

= 25

The number of games a girl play against another.

It is a combination problem so the total number of games:

= 10

A fraction of the games are boy-versus-boy:

The number games boy-versus-boy = 10

The number games Boy vs Boy & Girl vs Girl & Boy vs Girl

= 10+10+25

=  45

So the fraction = 10/45 ⇒ 2/9

If Anita is one of the club members then Anita will have to play against 9 people at the tournament.

Total number of games = 45

Then the fraction = 9/45 ⇒ 1/5

Thus, the total number of games a girl play against a boy is 25, the number of games a girl plays against a boy is 10, the fraction of the games are boy-versus-boy is 2/9, and 1/5 fraction of all games at the tournament Anita play the game.

Answer: 32 buttons

Step-by-step explanation:

Matt has 11 white buttons.

Matt has 9 fewer brown buttons than white buttons. This means he has (11 -9) = 2 brown buttons

Matt has 17 more grey buttons than brown buttons. This means that he has (2 + 17) = 19 grey buttons.

The total number of buttons that Matt has will be;

= 11 white + 2 brown + 19 grey

= 32 buttons

Answer:

C

Step-by-step explanation:

Given

(- 2x - 3) - (3x² - 8x + 9) ← distribute parenthesis

= - 2x - 3 - 3x² + 8x - 9 ← collect like terms

= - 3x² + 6x - 12 → C

Answer:

Step-by-step explanation:

Given:

A shelf is built on a wall. The angles of the triangle are given as (x + 3)°, (2x - 18)° and 90°

We need to determine the value of x.

Value of x:

By triangle sum property, the angles in a triangle always add up to 180°

Thus, we have;

Simplifying, we get;

Subtracting both sides by 75, we get;

Dividing both sides of the equation by 3, we get;

Thus, the value of x is 35.

Answer:

51

Answer:  D. 78

Step-by-step explanation:

71 73 74 75 78 85 85 90 97

(order them in numerical value, least to greatest)

take off one number from each side until you have one number left

Answer: 78

Step-by-step explanation: The median is the middle number in a sorted, ascending or descending, list of numbers and can be more descriptive of that data set than the average. Write all of the numbers and cross out a even amount of numbers on both sides. Image 1 shows your problem. If your problem had another number, you solve it differently. Check image 2.

Answer:

1/12

Step-by-step explanation:

1/4 X 1/3 = 1/12

Answer:

1/12

Step-by-step explanation:

When multiplying fractions, you multiply it like normal numbers, so 1 is multiplied by 1, and 3 is multiplied by 4.

For example:

3/4 x 9/10 would be equal to 27/40 because the 3 is multiplied by 9 and 4 is multiplied by 10.

3 x 9 = 27

4 x 10 40

27/40

Therefore on your question it would be 1/12.
