Xy = 450

y = x/2 => x=2y  substituted inside first equation will get 2y*y=450 => y^2 = 225

y=15 because 15*15=225

x=2y so x=2*15 = 30 

x=30
y=15

hope this will help you

Answer:

\frac{1}{2}y\cdot y=450

Step-by-step explanation:

Let x represent 1st number and y represent 2nd number.

We have been given that the product of two numbers is 450. We can represent this information in an equation as:

x\cdot y=450...(1)

We are also told that the first number is half the second number. We can represent this information in an equation as:

x=\frac{1}{2}y...(2)

To solve for greater number ,y, we will substitute equation (2) in equation (1) as:

\frac{1}{2}y\cdot y=450

Therefore, our required equation would be \frac{1}{2}y\cdot y=450.

1.a sphere with a radius of three units

 
By definition, the volume of a sphere is:
 V = ( \frac{4}{3} ) (\pi) (r ^ 3)

 Substituting values we have:
 V=(\frac{4}{3})(\pi)(3^3)
 Rewriting we have:
 V = (4) (\pi) (3 ^ 2)

V = (4) (\pi) (9)

V = 36\pi

 2.a cone with a diameter of twelve units and a height of three units
 
 By definition, the volume of a cone is given by:
 V =  \frac{1}{3}  (\pi) (r ^ 2) (h)

 Substituting values we have:
 V =  \frac{1}{3} (\pi) ((\frac{12}{2}) ^ 2) (3)

 Rewriting we have:
 V = (\pi) (6 ^ 2)

V = 36\pi
