Asculptor wants to create a statue. she goes to a quarry to buy a block of marble. she finds a chip of marble on the ground. the volume of the chip is 15.3 cm^3. the mass of the chip 14.3 grams, the sculptor purchases a block of marble 30.0-by-40.0-100.0 cm. use a proportion to find the mass of her block of marble.

we know that

the volume of the chip is 15.3 cm^3. the mass of the chip 14.3 grams

so

Step 1

Find the volume of a block of marble 30.0-by-40.0-by 100.0 cm

the volume is equal to

Step 2

Find the mass of a block of marble

by proportion

therefore

the answer is

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x

c) the median for town a 30" is greater than the median for town b 25"

step-by-step explanation:

town a, median = q2 = 30

town b, median - q2 = 25

so the median for town a 30" is greater than the median for town b 25"
