Shift the decimal points of both 8.7 and 53.07 to the right by 2 decimal places.

(This is needed to convert 53.07 to 5307, since long division must divide by a whole number.)

870/5307

Set up the long division.

5307|870

Therefore your answer should be 0.1639.

Hope I help! Please check my questions please. I need major help on the question.

You row upstream at a speed of 2 mi/h. You travel the same distance

Reika [66]

Answer:

3.5 m/hr

Step-by-step explanation:

2 + c = 5 -c c = speed of current

2 c = 3 c = current speed = 1.5 m/hr

your speed = 5 - 1.5 (or 2 + 1.5) = 3.5 m/hr

What quadratic formula do I need to use to solve 3x(x+6)=-1

timofeeve [1]

Answer:

$\Large \boxed{x_1=\frac{9+\sqrt{51} }{3} \ \ ; \ \ x_2=\frac{9-\sqrt{51} }{3} }$

Step-by-step explanation:

$\displaystyle \Large \boldsymbol{} 3x(x+6)=-10 \\\\3x^2+18x=-10 \\\\3x^2+18x+10=0 \\\\D=324-120=204 \\\\ x_{1;2}=\frac{18\pm2\sqrt{51} }{6} =\frac{9\pm\sqrt{51} }{3}$

What transformations change the graph of f(x) to the graph of g(x)?

Dennis_Churaev [7]

For this case we have that the main function is given by:

$f (x) = - 7x ^ 2$

We apply the following transformations:

Vertical expansions:

To graph y = a * f (x)

If a> 1, the graph of y = f (x) is expanded vertically by a factor a.

For a = 5 we have:

$h (x) = 5 * f (x)\\h (x) = 5 * (- 7x ^ 2)\\h (x) = - 35x ^ 2$

Vertical translations:

Suppose that k> 0

To graph y = f (x) + k, move the graph of k units up.

For k = 5 we have:

$g (x) = h (x) + k\\g (x) = - 35x ^ 2 + 5$

Answer:

The graph of g (x) is the graph of f (x) stretched vertically by a factor of 5 and translated up 5 units.

Someone?! answer please

Sonbull [250]

The answer is "$94."

If all 6 friends spent $420 on kayaks, and $144 on food, then they spent $564 in total. Divide $564 by 6 people to see how much each person payed.

420+144=564
564÷6=94
