Answer:
It is A.
Step-by-step explanation:
also, this is one question. A, B, C and D are just answers.
Answer:
≈ 6360 m³
Step-by-step explanation:
Volume of a cylinder = πr²h
radius = 12 m, h= 42.2 m
Therefore; V = 3.142 × 12² × 42.2
= 19093.3056 m²
Since the tank 1/3 full of water;
Volume = 1/3 × 19093.3056 m³
= 6364.4352 m³
≈ 6360 m³
So it gives you the "= 210" part of it so you just need to figure out how to write "40% of a number is added to the number"
the questions already tells you that "the number" is "x"
so that means "40% of x is added to x"
instead of writing "add" you can replace it with a plus sign "+"
(40% of x) + x
another way to write 40% of x is 0.40x
so your equation is .4x + x = 210
D again because as you can see....it does not touch the x axis at all, but the y axis is at -8
