Answer:

The constant of variation in a direct variation is the constant (unchanged) ratio of two variable quantities. The formula for direct variation is. y = k x (or y = k x ) where k is the constant of variation . Example 1: If y varies directly as x and y = 15 when x = 24 , find x when y = 25 .

Mrs. Parker cut a watermelon into fourths. She gave 1 piece to her 3 children to share equally. How much will each child eat?
beks73 [17]

Answer: ¹/₁₂ watermelon

Step-by-step explanation:

Mrs. Parker had a watermelon which she cut into fourths and then gave one of those pieces to her children.

This means that she gave them 1/4 of a watermelon.

There are 3 children and they are to share this piece equally:

= 1/4 ÷ 3

= 1/4 * 1/3

= 1/12

<em>Each child will get 1/12 of the water melon. </em>

X is the sum of y consecutive integers. w is the sum of z consecutive integers. If y = 2z, and y and z are both positive integer
zlopas [31]

Answer:

The answer is C.

Step-by-step explanation:

The key to solve the problem is the equation given

y = 2z         which means that<u> y is always an even number.</u>

For example:

let z = 1;       y  = 2(1)     y = 2;

let z = 2;      y  = 2(2)     y = 4;

let z = 3;      y  = 2(3)     y = 6;

And we know that for any set of consecutive integers with an even number of terms, the sum of the integers is never a multiple of the number of terms.

For example:

Set of numbers: [1,2,3,4,5,6] ;

Sum of the set:  1+2+3+4+5+6 = 21 ;

Number of terms of the set: 6;

Therefore, 21 is not a multiple of 6.

But for any set of consecutive integers with an odd number of terms, the sum of the integers is always a multiple of the number of terms.

For example:

Set of numbers: [1,2,3,4,5,] ;

Sum of the set:  1+2+3+4+5 = 15 ;

Number of terms of the set: 5;

Therefore, 15 is a multiple of 5.

And that's why we know that if y is always an even number (y = 2z), the sum of the consecutive integers (x) is not a multiple of y, therefore x/y cannot be an integer.
