so calculate the Volume of the water that is already in the tank
so l x w x h
4 x 18 x 12
=864cm^3 is in the tank
find the total volume of the tank:
6 x 18 x 12
=1296cm^3
and subtract the current from the total to find what you need:
1296cm^3 - 864cm^3
= 432 cm^3
you can also find how much you need by using the remaining 2cm from the height (6-4=2) and use the volume formula with 2 substituted as the height and you’ll get the same answer
Answer:
4x2 + 7x - 6

x - 2

Answer: A
Step-by-step explanation:
Answer:
5.7m
Step-by-step explanation:
the easiest way to solve for a side is to draw the question in a diagram (i have done this below). As it is a right-angled triangle and we know 2 of the side, we can use the Pythagoras theorem:
sides a and b are the two shorter sides.
side c is the hypotenuse (longest side)
as shown in the picture below, because we know both sides c and b, we need to change the equation around:

replace these sides with their numbers:
(remember that 32 equals side a squared therefore we need to square root 32 to find the length of side a:

the question says to round to the nearest tenth meter:
Missing side = 5.7m
I hope this was helpful :-)
