Aball has a mass of 50g and a volume of 20.3cm^3. what is the density of the ball?

Density of ball is 2.463 grams per cubic centimeter

Solution:

Given that ball has a mass of 50 grams

Volume =

To find: density of ball

The denisty is given by formula:

Where,

is the density

m is the mass

v is the volume

Substituting the known values in formula, we get

Thus density of ball is 2.463 grams per cubic centimeter

first option

a function is a relation in which an input is paired with exactly one output.

so, let's find the right answer.

in our first option, our inputs are january, february, and march. the outputs are 30, 28, and 25. each input has it's own output. this is correct!

our second option we know is incorrect, because ms. valverade has two outputs, dogs and cats. this is not a function.

our third option is incorrect as well. the yellow square has two ouputs, the square and the triangle.

lastly, in our fourth option, we see the number 7 two times with a different output. therefore, this is not a function.

remember: each input must be paired with only one output!

i think the answer is b x = 1, y = 35/2
