Answer:
weight of a water=0.5
spherical ball is filled With water=0.95.
so dear for
22\7*0.5*0.95=1.49
Answer:

Step-by-step explanation:
Slope intercept form of a line is given by:

Where
m is the slope and b is the y-intercept
Given slope is 
We can write:

Now to find b, we replace x with -3 and y with -4, given, so we have:

So, the equation is:

Now,
The standard form is given by:

So, we take x and y to left side and the constant to right side. Rearranging, we get:

The first answer choice is right.
57.5 is the answer. Because think of 200 as 100% and 15 out of a hundered is ______. Right.
