Yes.
They both will end with the equation
.. y = -2x +9
The answer is the last one; to express very large or small numbers.
We use it so we can show big or very small numbers in an easier way.
2/5 van not be simiplified because 2 and 5 dont have a common factor lower than them
Answer:
118.2
Step-by-step explanation:
1.1m is 100%
2.4m×100=240
240/1.1= 218.(18)
218.(18)%-100%=118.(18)=118.2
Answer:
43200 yd³
Step-by-step explanation:
The water reservoir is a rectangular solid that is a three dimensional shape with six quadrilateral faces (cuboid).
This reservoir has a base of 60 yards by 30 yards, and a vertical height of 30 yards. Therefore:
Volume of the reservoir = area of base * vertical height = 60 * 30 * 30 = 54000 yd³
This reservoir hence have a volume of 54000 yd³ when filled up with water.
After 3 months, the height of the water was down to 6 yards therefore the the volume is:
Volume after 3 months = area of base * vertical height = 60 * 30 * 6 = 10800 yd³
The amount of water used after 3 months = volume of water at beginning - volume of water after 3 months
The amount of water used after 3 months = 54000 - 10800 = 43200 yd³
