Anything to a negative power makes it inverse and 1/2 power is just square root.
Therefore 49^-1/2 is 1 divided by the square root of 49. The square root of 49 is 7 so the answer is 1/7.
Answer:
The answer is 5th angle = 
Step-by-step explanation:
Given that pizza is divided into six unequal slices.
Largest slice has an angle of 
.
He eats the pizza from largest to smallest.
Let the difference in angles in each slice = 
1st angle =
2nd angle = 90-d
3rd angle = 90-d-d = 90 - 2d
4th angle = 90-2d-d = 90 - 3d
5th angle = 90-3d-d = 90 - 4d
6th angle = 90-4d -d = 90 - 5d
We know that the sum of all the angles will be equal to 
(The sum of all the angles subtended at the center).
i.e.
So, the angles will be:
1st angle =
2nd angle = 90- 12 = 78
3rd angle = 78-12 = 66
4th angle = 66-12 = 54
5th angle = 54-12 = 42
6th angle = 42 -12 = 30
So, the answer is 5th angle =
| 3x - 1 | + 7 = 2
| 3x - 1 | = 2 - 7
| 3x - 1 | = -5.....no solution because an absolute value cannot equal a negative number.
| 2x + 1 | + 4 = 3
| 2x + 1 | = 3 - 4
|2x + 1 | = -1...same thing...no solution..cannot equal a neg. number
so Eq. 1 and Eq. 2 both have NO SOLUTIONS :)
Answer:
Let's say that the whole book have 5a pages.
First day: a + 12
Second day: (4a)1/4+15= a + 15
Third day: (1/3)[ 4a - (a+15)] +18= a + 13
Forth day: 70
So we get this:
(a + 12) + (a + 15) + (a + 13) + 70 = 5a
a + 12 + a + 15 + a + 13 + 70 = 5a
3a + 110 = 5a
3a - 5a = -110
-2a = -110
a = 55
5a = 5(55) = 275
So the total pages are in the book is:
275 pages
