A rectangular prism has a volume of 750 cubic millimeters. Its length is 15

umka2103 [35]

Answer: 5 milimeters.

Step-by-step explanation:

The formula for calculate the volume of a rectangular prism is:

$V=lwh$

Where "V" is the volume, "l" is the lenght, "w" is the width and "h" is the height.

You know that the volume, the lenght, and the width of this rectangular prism are:

$V=750mm^3\\l=15mm\\w=10mm$

Substitutute these values into the formula and solve for the the height "h":

$750mm^3=(15mm)(10mm)h\\\\h=\frac{750mm}{(15mm)(10mm)}\\\\h=5mm$

What is the radius of a circle whose equation is x2 + y2 – 10x + 6y + 18 = 0?

antoniya [11.8K]

You can do this by completing the square on x and y terms:

x^ - 10x + y^2 + 6y + 18 = 0

(x - 5)^2 -25 + (y + 3)^2 - 9 + 18 = 0

(x - 5)^2 + (y + 3)^2 = -18 + 9 + 25 = 16

so radius = sqrt16 = 4 answer
