Answer:
x = 1.1, -1.1
Step-by-step explanation:
This is the answer because:
1) Take the root of both sides and solve.
= 1.1
2) x can also equal -1.1 because -1.1 times -1.1 gives us a positive 1.21 because negative x negative = positive
Hope this helps!
Using the geometric mean concept, it is found that the value of a is 18.
----------------------
The geometric mean, of a data-set of n elements,
, is given by:
![G = \sqrt[n]{n_1 \times n_2 \times ... \times n_n}](https://tex.z-dn.net/?f=G%20%3D%20%5Csqrt%5Bn%5D%7Bn_1%20%5Ctimes%20n_2%20%5Ctimes%20...%20%5Ctimes%20n_n%7D)
That is, the nth root of the multiplication of all elements.
----------------------
In this question:
- Two elements(n = 2), a and 34.

Thus:

We find the square of each side, so:


Simplifying both sides by 17:



The value of a is 18.
A similar example is given at brainly.com/question/15010240
Cost of each shirt bought by Brain = 14.50
Then
Cost of 2 shirts bought by Brain = 2 * 14.50
= 29
Cost of a pair of shoes = 29.99
Total amount spent by Brain before tax = 29 + 29.99
= 58.99
Percentage of sales tax that needs to be paid = 6%
Amount of sales tax that needs to be [paid = (6/100) * 58.99
= 353.94/100
= 3.54
So
the total amount spent by Brain including tax = 58.99 + 3.54
= 62.53
I hope this is the answer you were looking for.
Answer:
4cm or 7 cm
Step-by-step explanation:
it can make 2 sides equal and make a isosceles triangle
There are 6 numbers on each die.
The total number of out comes is 6 x 6 = 36.
To get a sum of 4, the combinations are: 1 & 3, 2 & 2 or 3 & 1.
To get a sum of 8, the combinations are: 1 & 7, 2 & 6, 3 & 5, 4 & 4, 7 & 1, 6 & 2, 5 & 3
The total of those combinations are: 3 + 7 = 10 total combinations of a sum of either 4 or 8.
The probability of either is 10/36, which can be reduced to 5/18.
