Answer:

3.5 * 10^-4 centimeters

Step-by-step explanation:

Here, we have one uranium atom having a diameter of 3.5 * 10^-8 centimeters.

We now want to find the sum of 10,000 uranium atoms diameters

Mathematically;

That would be ;

3.5 * 10^-8 * 10,000

But 10,000 = 10^4

Thus, we have

3.5 * 10^-8 * 10^4

= 3.5 * 10^-4 centimeters

Describe the steps you would take to solve for the variable x in the following

adoni [48]

Answer:

x = 19

Step-by-step explanation:

1. add 31 on both sides (you wanna get the "x" by itself)

ex: 2x - 31 = 7

+31 +31

2. the 31s cancel each other out so now you add 31 + 7

2x = 7

+31

___________

3. divide 2 on both sides so the 2s cancel each other out and only the x is left

ex: 2x / 2 = x 38 ( the 38 stands alone)

4. now divide 38/2 and you have your answer

X= 19

Can anyone solve 84=4(1 - 4g) step by step?

lyudmila [28]

Answer:

g= -5

Step-by-step explanation:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

84-(4*(1-4*g))=0

84 - 4 • (1 - 4g) = 0

3.1 Pull out like factors :

16g + 80 = 16 • (g + 5)

16 • (g + 5) = 0

4.1 Solve : 16 = 0

This equation has no solution.

A a non-zero constant never equals zero.

4.2 Solve : g+5 = 0

Subtract 5 from both sides of the equation :

g = -5

What times what equals 59

sweet-ann [11.9K]

59 is a "prime number". It has no factors except ' 1 ' and itself.

So the only possibility is 1 x 59 .

If the following system of equations was written as a matrix equation in the form AX = C,? and matrix A was expressed in the for

Tomtit [17]

The value of the expression a - b + c + d will be 7.

<h3>What is the matrix?</h3>

A matrix is a specific arrangement of items, particularly numbers. A matrix is a row-and-column mathematical structure. The a_{ij} element in a matrix, such as M, refers to the i-th row and j-th column element.

The system of equations are given below.

5x + 7y = 7

3x - 2y = 9

Then the equations can be written in the form of matrix. Then we have

$\begin{bmatrix}5 & 7 \\3 & -2 \\\end{bmatrix} \begin{bmatrix}x \\y \\\end{bmatrix} = \begin{bmatrix}7 \\9 \\\end{bmatrix}$

Then the value of a, b, c, and d will be

a = 5, b = 3, c = 7, and d = -2

Then the value of the expression will be

a - b + c + d = 5 - 3 + 7 - 2

a - b + c + d = 12 - 5

a - b + c + d = 7

More about the matrix link is given below.
