10/12 in simplest form is 5/6.
Equivalent ratios would be 15/18, 20/24, and 25/30.
The rest is easy, give it a try.

Step-by-step explanation:
Area of shaded region is 18π square unit.
<u>Step-by-step explanation:</u>
Given :- A circle with center O and radius 9 cm
To Find :- area of shaded region that is area of ABC
Solution : - BC = 9 cm
∠ABC = 80° = Ф
so, area of sector = πr²Ф / 360°
= (π×9×9×80) /360°
= 18π square unit
hence, area of shaded region is 18π square unit
Answer:
The formula is:
Step-by-step explanation:
The geometric sequences are those in which the division between the terms 
and 
of the sequence are equal to a constant common reason called "r"
The geometrics secencias have the following form:
Where 
is the first term of the sequence
In this sequence we have the following terms
1.2, 3, 7.5, 18.75
Then notice that:
Then:
and 
Finally the formula is:
3) an $8 delivery fee and $1.50 per litre of water
This is because the $8 is a constant baseline, then adding $1.50 times the amount of litres purchased.
