2/5 x 0.22= I need to know this answer

2/5 x 0.22 = (2 x 0.22)/5 = 0.44/5 = 0.088 = 11/125

11/125

Step-by-step explanation:

Convert 2/5 to a decimal, which would be 0.4.

So then all you have to do is multiple them together.

0.4 × 0.22 = 0.088.

0.088 as a fraction would be 88/1000.

Then you have to simplify as much as possible.

The highest common factor is 8

This would then equal 11/125

Hope this helps :)

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
