Answer:
James has an ice cube tray that makes ice in the shape of spheres rather than cubes. Each sphere of ice has a radius of 2 cm. One tray makes 6 spheres.What is the total volume of ice the tray can make at one time?
Total volume of the tray James have = 201.06 cm^3
Step-by-step explanation:
Given:
Radius of the spherical ice cube = 2 cm
No. of spheres in the ice cube = 6
We have to find the total volume of the ice tray that can make at one time.
Let the total volume be "V".
Formula to be used:
Volume of sphere = 
cubic unit.
Total volume = 
cubic unit.
So,
Total volume of the ice tray (V) :
⇒ 
⇒ Plugging n = 6 and r = 2
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
So,
The total volume of ice the tray can make at one time = 201.06 cm^3
Area of Consuela's rectangular living room = 360 square feet
Let us assume the the length of the living room = x
Then
width of the living room = (5/8) * x
= (5x/8)
Then
Area of the rectangle = Length * Width
360 = x * (5x/8)
360 = 5x^2/8
2880 = 5x^2
x^2 = 2880/5
x^2 = 576
x^2 = (24)^2 inches
x = 24
Then
The length of the rectangle is = 24 inches
And
The Width of the rectangle is = 24 * (5/8) inches
= 3 * 5 inches
= 15 inches
It will never happen because you are increasing a even number with a even number so it will always be even and a odd with a even will make odd every time
Answer:
- 2x +3(8 -3x) = 3
- x = 3
- y = -1
Step-by-step explanation:
The second equation tells you ...
y = 8 -3x
Using this expression in the first equation gives you ...
2x +3(8 -3x) = 3
2x +24 -9x = 3 . . . . . eliminate parentheses
21 = 7x . . . . . . . . . . . add 7x -3
3 = x . . . . . . . . . . . . . . divide by 7
y = 8 -3×3 = -1 . . . . . . use the second equation to find y
The solution is (x, y) = (3, -1).
