Answer:
The density of cube is 6.17959 
Step-by-step explanation:
The density is given by ration of a mass of body and volume occupied by a body.

Where,
is density.
m is mass of a body
V is the volume of a body
Given that one side of the cube is 0.53cm
Hence, the volume of a body is V=
=0.148877
Now, the Density of the cube will be



Thus, The density of cube is 6.17959 
Answer:
$=19400
Step-by-step explanation:
Average prices= $18,500
Number of prices that were quoted= 7
Expected sum that produces this mean= 7*18,500=$129,500
Sum of quoted prices=
$(15,500+ 18,800+ 16,900+ 19,900+18,000+21,000) =$110100
Next price to be quoted will be ;
$129,500-$110,100
$=19400
For the answer to the question, what is t<span>Ten times the square of a nonzero number is equal to forty times the number</span><span>10∗x2=40x</span>the question's statement<span>x2−4x=0</span>simplifyx(x−4)=0factor out an x x=0,x=4 the two solutions
The answer is A) x = 6
<span>3(4x-3) - 19 = 8x-4
12 x - 9 - 19 = 8x - 4
12x - 8x = -4 + 9 + 19
4x = 24
4x / 4 = 24 / 4
x = 6</span>
