Lisa is using plastic spheres to compare the size of Earth and Mars. The diameter
of Earth's sphere is 2 times larger than the diameter of Mars's sphere. How does
the volume of the model of Earth compare to the volume of the model of Mars?
(Hint: Draw a picture AND/OR Give Earth and Mars numeric values, and try to
find the volume using the formula)
The model of Earth will have 2 times more volume than the model of Mars.
The model of Earth will have 4 times more volume than the model of Mars.
The model of Earth will have 6 times more volume than the model of Mars.
The model of Earth will have 8 times more volume than the model of Mars.

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.

i would say b) is your answer

sorry if im wrong

step-by-step explanation:

answer: the is put the 450

step-by-step explanation:

since we know that the two functions are equal, f (x) = g

(x), therefore when we equate the two equations the result should be similar to

3x = x – 4:

a. f(x) = 3x, g(x) = x – 4

equating the two functions:

3x = x – 4             (correct)

so we now got our answer (a)
