Answer:
11 kg
Explanation:
Given weight in kg ∝ d² where d is the distance of the object from the center of the earth
We can write this as an equatio
w = (k/d²) where is a constant
On the surface of the earth, d = 600, w = 80 so we get
80 = k/600² ==> k = 600² ( 80) = 600 x 600 x 80 (1)
At 1000 km altitude, the actual distance of the astronaut from the center of the earth is 1000 + 600 - 1600 km
So we get another equation w' = k/1600²
were w' is the weight of the astronaut at an altitude of 1000km
Using the value of k from (1) we get
w' = (600 x 600 x 80)/(1600 x 1600) = 11.25kg = 11 correct to the nearest kg
By using the given ratio, we will see that the diagonal measures 50 inches.
<h3>
How to get the diagonal of the screen?</h3>
First, we know that the ratio between length and width is 16:9, and the length is 43.6 inches, then the width will be:
W = (9/16)*43.6 inches = 24.5 in
Now, the diagonal will be equal to the hypotenuse of a right triangle with catheti of 43.6 in and 24.5 in, by using Pythagorean's theorem we get:
We conclude that the diagonal measures 50 inches.

The sum of n odd numbers n², where n is a natural number and represents the number of terms.
<h3>What is a natural number?</h3>
The numbers that we use when we are counting or ordering, which occurs commonly and obviously in nature.
Here, given all the odd numbers from 1,3,5,7..........999.
The sum of n odd numbers, n².
999² = 998001
Thus, the sum of all the odd numbers from 1 to 999 is 998001.

For h = 60 + 2.5f, where h = height, in cm, and f = femur length, in cm, and the condition that h > 160cm., the minimum condition for f to meet the requirement for h will be:If h=160cm,f’ = (160-60) /2.5f’ = 40cm,with f’ = 40cm not being a solution to this inequality.
That is, all values greater than 40cm will solve the said inequality which is expressed as:f > (h-60)/2.5
Answer:
When America entered World War I, the number of women in the workforce increased. Their employment opportunities expanded beyond traditional women's professions, such as teaching and domestic work, and women were now employed in clerical positions, sales, and garment and textile factories.
