The short piece is 3 feet long

Step-by-step explanation:

The given is:

  • Mildred cut a 9 foot board into two pieces
  • The long piece is twice as long as the short one

We need to find how long is the short piece is

Assume that the length of the short piece is x feet, and the length of long piece is y feet

∵ x represents the length of the short piece

∵ y represents the length of the long piece

∵ The length of the board is 9 foot

∴ x + y = 9 ⇒ (1)

∵ The long piece is twice as long as the short one

∴ y = 2x ⇒ (2)

Now we have a system of equation to solve it

Substitute y in equation (1) by equation (2)

∵ x + 2x = 9

- Add like terms

∴ 3x = 9

- Divide both sides by 3

∴ x = 3

∵ x represents the length of the short piece

∴ The length of the short piece is 3 feet

The short piece is 3 feet long

Jae Li creates this solid wooden sculpture for an art project.
Dafna1 [17]
The volume of the sculpture will be found by partition he sculpture such that we find the volume of different parts as follows:
volume of cuboid is given by:
v=length*width*height
thus the volume of the sculpture will be:
Volume=(15*4*4)+(10*4*4)+(5*4*4)
volume=240+160+80
volume=480 cubic inches

Convert the rate 1000 fluid ounces per 2 hours to cups per minute
Ronch [10]
There are 8 ounces in a cup, so there are 125 cups in 1000 ounces.
1000 / 8 = 125
there are 60 minutes in an hour and 120 minutes in 2 hours
so 1000 ounces / 2 hours is
125 cups / 120 minutes
125 / 120 = 1.04 cups per minute

Check your work
multiply times 60 to get cups per hour
1.04 * 60 = 62.4 cups per hour
multiply times 8 to get ounces per hour
62.4 * 8 = 499.2
multiply times 2 to get ounces per 2 hours
499.2 * 2 = 998.4
the number is not quite 1000 due to rounding the 125 / 120 as it is closer to 1.041666666666667
