Answer:

25.691 when rounded to tenth , if number after decimals is greater than or equal to 0.5 , so we have to add 1 to the number which is at unit place.

So,→ 25.691 when rounded to greatest place =26

→25.691 when rounded to nearest Tens =30, because number at the unit digit is greater than or equal to 5.

In order to round 25.691 to the greatest place or the nearest whole number, first start at the last digit behind the decimal, in the case, being the 1. When it comes to things like this, if the digit is 4&under meaning its the number 4,3,2,1 or 0. If it is 5&up, that means it could be 5-9, making the digit go up (but if its 2, then the digit just goes away, you wont have to worry about that one specific number).

Next step is to round the 9 which makes the 6 go up one digit (meaning it turns into a 7). Now, when you round the seven, it will make the whole number go up one digit, but if you want to round that as well, to start, it's first rounding equaled up to 26. If you're rounding it to a whole tens number, it would be 30. I hope that this helps you understand this subject or topic much better! :3

What are the possible values of x in 8x2 + 4x = -1?

Westkost [7]

Answer:

The possible values of x are:

x= $\frac{-1+\sqrt{3}}{4} \,\,or\,\, x= 0.18$

and

x= $\frac{-1-\sqrt{3}}{4} \,\, or \,\, x= -0.68$

Step-by-step explanation:

$8x^2+4x+1=0$

Using Quadratic formula to solve this equation:

$x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\\a = 8 \,\, b = 4\,\, c = -1\\Putting \,\, values \,\, in \,\, the\,\, equation\\x= \frac{-4\pm\sqrt{(4)^2-4(8)(-1)}}{2(8)}\\x= \frac{-4\pm\sqrt{16+32}}{16}\\x= \frac{-4\pm\sqrt{48}}{16}\\x= \frac{-4+ \sqrt{48}}{16} \,\, and \,\, x= \frac{-4- \sqrt{48}}{16}\\x= \frac{-1+ \sqrt{3}}{4} \,\, and \,\, x= \frac{-1- \sqrt{3}}{4}$

The possible values of x are:

x= $\frac{-1+\sqrt{3}}{4} \,\,or\,\, x= 0.18$

and

x= $\frac{-1-\sqrt{3}}{4} \,\, or \,\, x= -0.68$

A classmate simplifies the expression in exercise 1. is the expression he wrote equivalent to the original expression? explain.

AlladinOne [14]

Excercise 1:

No, this is not simplified fully. The full answer would be −7dk+14d−21k−7, not 14d - 9 - 21k - 7dk + 2. So, it is not equivalent.

Excercise 4:
7dk (2 - 3 - 1) - 7

Just multiply 7dk into (2) (-3) and (-1)
you'd get:
−14dk+−7 after simplifying it fully.

p = parameter
w = width

Answer:

2 for $0.25

Step-by-step explanation:

1.10/ 6= .20 (rounding)

1.00/ 5= .20

0.85/ 4= .21

0.25/ 2= .13 (rounding)

A professional baseball team won 84 games.The team won 14 more games than it lost.There were no ties.How many games did the team

babunello [35]

Hello There!

Games won = 84
Games lost = 84 - 14
Games lost = 70
Total games played = games lost + games lost
Total games played = 84 + 70
Total games played = 154.

They played 154 games and lost 70 games.

Hope This Helps You!
Good Luck :)
