Answer:

0.00324 or in scientific notation  3.24×10^-3

Step-by-step explanation:

MASS OF SINGLE ELECTRON = 5.4×10^-4

MASS OF 6 ELECTRONS = 6× 5.4×10^-4

                                           =32.4×10^-4

                                            = 3.24×10×10^-4

                                             = 3.24×10^-3

If JM = 5x – 8 and LM = 2x – 6, which expression represents JL?
muminat

Answer:

The expression represents JL is<u> 3x - 2</u>.

Step-by-step explanation:

Given:

JM = 5x – 8 and LM = 2x – 6.

Now, to find expression represents JL.

JM = JL + LM

<em>Subtracting both sides by LM we get:</em>

JM - LM = JL.

JL = JM - LM

Now, putting the expression to get JL:

JL=5x-8-(2x-6)

JL=5x-8-2x+6

JL=3x-2.

Therefore, the expression represents JL is 3x - 2.

The answer is D

To solve the answer you would have needed to multiply the reciprocal of \frac{2}{7} but in this case, Unvi multiplied with the reciprocal of 14.

Volume? Correct answers please
goldfiish [28.3K]

Answer:

V = 1385.44

Step-by-step explanation:

The equation for volume is V = π r 2 h! Where V = volume, r = radius <em>(half the diameter)</em>, and h = height. Now lets substitute what we know into this equation!

<em>Since we are giving the diameter (14) we must divide by 2 to find the radius.</em>

                         14 ÷ 2 = 7

Radius = 7

Height = 9

V = ?

Time to plug these values in!

V = π 7^{2} (9)

<em>We have to distribute </em><em>pi to 7 square that term </em><em>and then </em><em>multiply the value by 9</em><em>. </em>

<em />

V = 1385.44

Hope this Helps! :)

A researcher gathered data on hours of video games played by school-aged children and young adults. She collected the following
antiseptic1488 [7]

Step-by-step explanation:

The complete frequency distribution table for the data has been attached to this response.

The frequency column contains values that are the number of times the given range of hours appear in the data. For example, numbers in the range 0 - 2 hours, appear <em>9</em> times in the data. Also, the numbers in the range 3 - 5 appear  <em>6</em> times. The same logic applies to other ranges.

The relative frequency column contains the ratio of the number of times the given range of hours appear in the data, to the total number of outcomes. The total number of outcomes is the sum of all the frequencies on the frequency column. This gives 38 as shown.

So, for example, to get the relative for the numbers in the range 0-2, divide their frequency (9) by the total outcome or frequency (38). i.e

9 / 38 = 0.24

Also, to get the relative for the numbers in the range 3-5, divide their frequency (6) by the total outcome or frequency (38). i.e

6 / 38 = 0.16

Do the same for the other ranges.
