How many 1 inch cubes do you need to fill a cube with an edge length of 7/12 foot
grigory [225]

Answer:

[you need 343 1 inch cubes]

Step-by-step explanation:

A foot has 12 inches. So if the edge length is 7/12 of a foot, that means that the edge length is 7 inches.

——————

[volume of a cube if the edge length is L, is L x L x L or L cubed]

A one inch cube has an edge length of 1. That means the volume of this cube is 1 x 1 x 1 = 1 inch cubed

——————

This big cube, has an edge length of 7 inches. So the volume is 7 x 7 x 7 = 343 inches cubed.

To find how many 1 inch cubes do you need to fill a 7 inch cube, you divide 343 by 1:

343/1=343 so you need 343 1 inch cubes.

The sum of two numbers is -26. One number is 148 less than the other. Find the numbers
maks197457 [2]

Answer:

61 and -87

Step-by-step explanation:

If the numbers are x and x - 148, we can write the following equation:

x + x - 148 = -26

2x - 148 = -26

2x = 122

x = 61 so x - 148 = 61 - 148 = -87

An individual needs a daily supplement of at least 464 units of vitamin C and 252 of vitamin E and agrees to obtain this supplem
hichkok12 [17]

Answer:

z (min)  = 705

x₁  = 10

x₂  = 9

Step-by-step explanation:

Let´s call  x₁  quantity of food I ( in ou )  and x₂ quantity of food II ( in ou)

          units of vit. C   units of vit.E   Cholesterol by ou

x₁                 32                      9                         48

x₂                16                      18                          25

Objective function z

z  =   48*x₁   +  25*x₂        To minimize

Subject to:

1.-Total units of vit. C at least  464

32*x₁   +  16*x₂     ≥   464

2.- Total units of vit. E at least  252

9*x₁  + 18*x₂   ≥  252

3.- Quantity of ou per day

x₁   +   x₂   ≤  35

General constraints    x₁  ≥ 0    x₂   ≥ 0

Using the on-line simplex method solver (AtoZmaths) and after three iterations the solution is:

z (min)  = 705

x₁  = 10

x₂  = 9

The graph of the piecewise function f(x) is shown what is the domain of f(x)
Rom4ik [11]

The domain of a function is where we have a value for x.

Since that's the case the domain of f(x) = {x e R / 1 ≤ x < 5}

We see that we have a value for x = 1 cuz we have a filled circle, but we don't have a value for x = 5, look at the unfilled circle

So, our x can vary between 1 and 5, but can't be 5.
