Answer:
- Earth is 85.71 times heavier than moon
- Jupiter is 333.33 times heavier than Earth
Step-by-step explanation:
Given
- The mass of Earth is about 6 x 10^24 kilograms = e
- The mass of the moon is about 7 x 10^ 22 kilograms = m
- The mass of Jupiter is about 2 x 10^27 kilograms = j
<u>The difference in mass</u>
- e/m = 6 x 10^24 / 7 x 10^ 22 = 600/7 = 85.71
Earth is 85.71 times heavier than moon
- j/e = 2 x 10^27 / 6 x 10^24 = 2000/6 = 333.33
Jupiter is 333.33 times heavier than Earth
133 adult tickets were sold.
Step-by-step explanation:
Given,
Total tickets sold for school play = 399
Let,
x represent the number of children tickets sold.
y represent the number of adult tickets sold.
According to given statement;
x+y=399 Eqn 1
x = 2y Eqn 2
Putting value of x from Eqn 2 in Eqn 1
![2y+y=399\\3y=399](https://tex.z-dn.net/?f=2y%2By%3D399%5C%5C3y%3D399)
Dividing both sides by 3
![\frac{3y}{3}=\frac{399}{3}\\y=133](https://tex.z-dn.net/?f=%5Cfrac%7B3y%7D%7B3%7D%3D%5Cfrac%7B399%7D%7B3%7D%5C%5Cy%3D133)
133 adult tickets were sold.

We will have the following:
*It will have a domain of x equal or greater than 0:
![x\ge0](https://tex.z-dn.net/?f=x%5Cge0)
It will have a domain of y equal or greater than 0:
![y\ge0](https://tex.z-dn.net/?f=y%5Cge0)
***
We have the following:
We determine the domain as follows:
Since the function is subject to a root, no negative value can be put in it, so its domain (Since x is not accompanied by any value in the root) can only "hold" values equal or greater than 0.
We determine the range as follows:
Since the function is subject to a root, it's solutions will never be negative, so its range can only hold values equal or greater than 0.
