Makovka662 [10]
First we have to setup system of equations for the given case.
Let x is the original number and y is the reverse three digit number.
Then,
x+y=665  Equation 1
x-y=297 Equation 2
Add both equations to get.
2x=962
Divide both sides by 2.
x=481
This is the original number. And reverse number is : 481+y=962
y=184

Here Hundredth digit is 4, and tenth digit is 8 which is 2 times of the hundredth digit. 

Answer: Number is 481

MaRussiya [10]

Answer:

  4)  0.001

Step-by-step explanation:

The amount (a) present in h hours is ...

  a(h) = (initial value)×(1/2)^(h/(half-life))

6 days is 6×24 hours, so the amount remaining is ...

  a(6×24) = 50×(1/2)^(6×24/9) = 50/2^16 ≈ 0.001 . . . . milligrams

A sphere has a diameter of 5 inches.
ozzi
By definition, the volume of a sphere is given by:
 V = (4/3) * ( \pi ) * (r ^ 3)&#10;
 Where,
 r: is the radius of the sphere
 The radius of the sphere is:
 r = d / 2&#10;
 Where,
 d: diameter of the sphere
 Substituting values we have:
 r = 5/2&#10;&#10;r = 2.5
 Then, the nolumen is given by:
 V = (4/3) * (3.14) * (2.5 ^ 3)&#10;&#10;V = 65.4 in ^ 3
 Answer: 
 
the volume of the sphere is:
 65.4 in³
