If 8 pigs can fit in a pen, how many pens are necessary to make sure 71 pigs are all in a pen?

Ulleksa [173]

Answer:

Step-by-step explanation:

Each pen can only hold 8 pigs, and pens cannot be split up into fractions.

Divide. 71 / 8 = 8.875

There is no 7/8 of a pen, so you must round up.

8.875 → 9.

What are the number of possible digits to round 1_9,644 to the nearest 100,000?

damaskus [11]

4 goes in the blank.

In math, if any number like that is 5 or higher, it rounds to the nearest tenth.

so for example, 4 would round down to 0, and 5 would round up to 10.

So with the 4, it Makes 149.6k, which rounds down to 100,000.

Answer:

$\bold{x_1=-\dfrac{3+\sqrt{41}}{2}\approx-4.7\ ,\quad x_2=-\dfrac{3-\sqrt{41}}{2}\approx1.7}$

Step-by-step explanation:

$-2x^2-3x+4=0\\\\a=-2\,,\ b=-3\,,\ c=4\\\\\\x=\dfrac{-b-\sqrt{b^2\pm4ac}}{2a}=\dfrac{-(-3)\pm\sqrt{(-3)^2-4(-2)(4)}}{2(-1)}=\dfrac{3\pm\sqrt{9+32}}{-2}\\\\\\x_1=-\dfrac{3+\sqrt{41}}{2}\approx-4.7\ ,\qquad x_2=-\dfrac{3-\sqrt{41}}{2}\approx1.7$
