What is an equation that relates weight on earth and weight on the moom

W=mg 

<span>Where: </span>

<span>Weight = mass * acceleration due to gravity </span>

<span>So let's say I want to work out my weight on the moon. I know I weigh about 70kg (which would be N), but I can't use that figure for the calculation on the moon. That is what I weigh on Earth, so let's look at the equation... </span>

<span>70kg = mass * 9.81m/s^2 </span>

<span>Where 9.81m/s^2 is the acceleration due to gravity on the surface on the earth. I want to get rid of that, so let's work out my mass by division; </span>

<span>70/9.81 = 7.14kg </span>

<span>I googled the acceleration of gravity on the Moon, which was = 1.6m/s^2 </span>

<span>Let's use that in the same equation W=mg </span>

<span>W = 7.14kg * 1.6m/s^2 = 11.42N

</span><span>On the Moon, you would weigh approximately one sixth of your weight on Earth, so if your bathroom scales tell you you weigh 120 pounds, there you would weigh 20 pounds.
</span>
<span>Moon`s gravitational pull is about one-sixth to the gravitational pull on earth hence weight on moon is about one-sixth of the weight on earth.</span>

kozerog [31]

Answer: 49.85%

Step-by-step explanation:

Given : The physical plant at the main campus of a large state university recieves daily requests to replace florecent lightbulbs. The distribution of the number of daily requests is bell-shaped ( normal distribution ) and has a mean of 61 and a standard deviation of 9.

i.e.  \mu=61 and \sigma=9

To find :  The approximate percentage of lightbulb replacement requests numbering between 34 and 61.

i.e. The approximate percentage of lightbulb replacement requests numbering between 34 and 34+3(9).

i.e. i.e. The approximate percentage of lightbulb replacement requests numbering between \mu and \mu+3(\sigma). (1)

According to the 68-95-99.7 rule, about 99.7% of the population lies within 3 standard deviations from the mean.

i.e. about 49.85% of the population lies below 3 standard deviations from mean and 49.85% of the population lies above 3 standard deviations from mean.

i.e.,The approximate percentage of lightbulb replacement requests numbering between \mu and \mu+3(\sigma) = 49.85%

⇒ The approximate percentage of lightbulb replacement requests numbering between 34 and 61.= 49.85%

A student claims that the expression “9 times the sum of a number and 13" is translated to the algebraic expression 9n + 13. Is
FrozenT [24]

Answer:

No, the student is not correct. The correct expression is 9(n+13).

Step-by-step explanation:

"9 times the sum of a number and 13" means you must multiply 9 by the sum, not just by the number. 9n + 13 would be "the sum of 9 times a number and 13." Slightly different wording.

1 7/8 divided by 3/4 can someone please help me
sesenic [268]
1. Change 1 7/8 to an improper fraction, which gives you 15/8.

2. Use KFC to divide fractions. KEEP the first term, FLIP the second and CHANGE to multiplication.

3. 15/8 x 4/3 = 60/24 = 2 1/2
