A book sold 35,300 copies in its first month of release. Suppose this represents 6.3 of the numbers sold to date. How many copie

skelet666 [1.2K]

Answer:

560,317.460

Step-by-step explanation:

The computation of copies that have been sold is shown below:-

we assume the number of copies is x

So, the number of copies in the first month is

= $\frac{6.3}{100} x$

As per the situation the number of sold copies is 35,300 so the equation will be

$\frac{6.3}{100} x = 35,300$

$6.3x = 35,300\times 100$

$x = \frac{35,300\times 100}{6.3}$

after solving the above equation we will get the number of copied that have been sold to date

= 560,317.460

Find an equation of a sphere if one of its diameter has endpoints (2,1,4) and (4,3,10)

lara31 [8.8K]

Answer:

$(x-3)^2+(y-2)^2+(z-7)^2 =11$

Step-by-step explanation:

Given that a sphere has one diameter having endpoints (2,1,4) and (4,3,10)

We can find the mid point of these two points and that would be the centre

If we find distance between these two points that would be twice radius.

Distance = 2r = $\sqrt{(4-2)^2+(3-1)^2+(10-4)^2} \\=\sqrt{44}$

So radius = $\sqrt{11}$

Centre of sphere = mid point of two points

= (3, 2, 7)

Using centre radius formula sphere has equation as

$(x-3)^2+(y-2)^2+(z-7)^2 =11$
