Alright, lets get started.
We have given the ratio 9:45
or
could be written as ![\frac{1}{5}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B5%7D%20%20)
Means the given ratio is 1:5.
Means every given number should be in this ratio 1:5.
? : 30 means
![\frac{x}{30} =\frac{1}{5}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bx%7D%7B30%7D%20%3D%5Cfrac%7B1%7D%7B5%7D%20%20)
Cross multiplying
![5x = 30](https://tex.z-dn.net/?f=%205x%20%3D%2030%20)
Hence x = 6
For 7 : ?
![\frac{7}{x} =\frac{1}{5}](https://tex.z-dn.net/?f=%20%5Cfrac%7B7%7D%7Bx%7D%20%3D%5Cfrac%7B1%7D%7B5%7D%20%20)
Cross multiplying
x = 35
For 8 : ?
![\frac{8}{x} =\frac{1}{5}](https://tex.z-dn.net/?f=%20%5Cfrac%7B8%7D%7Bx%7D%20%3D%5Cfrac%7B1%7D%7B5%7D%20%20)
Cross multiplying
x = 40
Hence the answers are 6 30, 7 35, 8 40. : Answer

The probability is 25% because the deck is divided into 4 parts which makes it 25% probability of choosing a club or a heart.
The volume (V) of prism is the product of the area (A) of the base and its height (h). The area of the square base is the square of its width, 3 cm.
144 cm³ = (3 cm)² x h
The value of h from the equation is 16. Therefore, the height of the prism is 16 cm.
