If the ribbon cost $0.10 per foot what is the total cost of the ribbon in dollars

WITCHER [35]

Well how long is the ribbon? I'm not asking for the dollar amount, I will answer your question if you can tell me the length of the ribbon. No one can figure it out unless you give the total length.

Factor Completely.3g^2-78g+75

Umnica [9.8K]

✧･ﾟ: *✧･ﾟ:* *:･ﾟ✧*:･ﾟ✧

Hello!

✧･ﾟ: *✧･ﾟ:* *:･ﾟ✧*:･ﾟ✧

❖ 3g^2 - 78g + 75 factored completely is $3(g-1) * (g-25)$

First, write the expression as a difference:

$3(g^{2} -26g +25)$

Then factor the expression:

$3(g^{2} - g - 25g + 25)$

Factor the expression again:

$3 (g*(g-1)-25(g-1))$

Your final answer should be:

$3(g-1)*(g-25)$

Natasha_Volkova [10]

Answer:

The equation will be " $y=-2.8 x+75$ ".

Step-by-step explanation:

The given values are:

Started with,

= 75 gallons

After 15 hrs,

Tank has,

= 33 gallons

Now,

The slope will be:

= $\frac{33-75}{15}$

= $\frac{-42}{15}$

= $-2.8$

Thus,

The equation is " $y=-2.5x+75$ ".
