No a sphere consisting of steel at some dimensions such as 3 ft^3 wouldn't weigh the same as a sphere of silicone at 3 ft^3

The objects will not always have the same mass because they might not be made of the same substance. Some substances are heavier or denser than others. For example; A plate made of clay will be lighter than one made out of gold or diamond. Also, if you fill a beaker with water and another with sand at the same level, you will notice that the beaker with sand will be heavier and weigh a lot more than the beaker with water. This is because sand is denser than water. Hope i helped. GOODLUCK.

Step-by-step explanation:

if x=1/4 then y=1/4-1/4=0

if x=13/4 then y=13/4-1/4=12/4=3

if x=2 then y=2-1/4=8/4-1/4=7/4=1 3/4

Please help me with this

So since 2/5 of the washing machines have been sold that means 3/5 remain in the store

first find the number of washing machines that were in the store before any were sold

X is the number of washing machines in the store before selling

18=(3/5)X

18/(3/5)=X
X=18*(5/3)
X=30

so at the beginning there were 30 machines

then multiply the percent sold (2/5) by the number at beginning to find the number sold

(2/5)*30=12

so 12 machines were sold

to find the cost per machine divide the total price by number of machines sold so

$3840/12= $320

so the answer is $320 per machine
