Every 6th voter gets a button. Every 7th voter gets a sticker. Which voter is the first to receive both items?

MrMuchimi

Answer:

Step-by-step explanation:

Use LCM of 6 and 7 to find a number that is the same:

6 12 18 24 30 36 42

7 14 21 28 35 42

Since 42 shows up in both, the 42th voter gets a button and sticker.

Hope this helped.

which equation is the quadratic variation equation for the relatonship? the variable y varies directly with x^2 and y=36 when x=

svetoff [14.1K]

For this case we have a direct variation of the form:

$y = kx ^ 2$

Where,

<em>k: proportionality constant </em>

We must find the value of k.

For this, we use the following data:

$y = 36\\x = 3$

Therefore, replacing values we have:

$36 = k (3) ^ 2$

Rewriting:

$36 = 9k$

Clearing the value of k we have:

$k = \frac {36} {9}\\k = 4$

Therefore, the direct variation equation is given by:

$y = 4x ^ 2$

Answer:

The quadratic variation equation for the relatonship is:

$y = 4x ^ 2$
