butalik [34]

Answer:

(a)\ t =\frac{d}{v}

(b)\ d = vt

Step-by-step explanation:

<em>The question is mixed up with details of another question. See comment for original question</em>

<em />

<u>Given</u>

v = \frac{d}{t}

v \to velocity

d \to distance

t \to time

Solving (a): Solve for time

We have:

v = \frac{d}{t}

Cross multiply

t * v = d

Make t the subject

t =\frac{d}{v}

Solving (b): Solve for distance

We have:

v = \frac{d}{t}

Cross multiply

d = v * t

d = vt

5/8 of an inch in percent
Dovator [93]
<h2>Greetings!</h2>

Answer:

62.5%

Step-by-step explanation:

To find the percentage, you simply need to divide the number on top by the number on bottom and multiply by 100:

5 ÷ 8 = 0.625

0.625 x 100 = 62.5

So the percentage is 62.5%!

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.
