Lin's teacher uses the box to store her set of cubes with an edge length of one half inch. if the box is completely full, how ma
nlexa [21]

Answer:

448 cubes

Step-by-step explanation:

Volume of cubes fitted in the box will be equal to the cumulative volume of the cubes.

Since, volume of a cube = (Side)³

Side of the cube = \frac{1}{2} inch

Therefore, volume of the cube = (\frac{1}{2})^3=\frac{1}{8} inches

Volume of the storage box = 56 cubic inches

Since, number of cubes fitted in the storage box = \frac{\text{Volume of the storage box}}{\text{Volume of one cube}}

                                                                                 = \frac{56}{\frac{1}{8}}

                                                                                 = 56 × 8

                                                                                 = 448 cubes

Therefore, number of cubes fitted in the storage box = 448

Mikes plumbing charges 68 for coming to your house and 17 per hour for labor if I paid him 357, how many hours, h, was mike at m
Roman55 [17]

Answer:

b. 68 + 17h = 357

f. 17 hours

Step-by-step explanation:

Charges for coming to my house = $68 (this will be the constant of the equation)

Amount charged per hour labor = $17

hours = h

Total amount paid to Mike = 357

The equation that represents this situation can be expressed as:

68 + 17h = 357

Solve for h

68 + 17h - 68 = 357 - 68 (subtraction property of equality)

17h = 289

\frac{17h}{17} = \frac{289}{17} (division property of equality)

h = 17

Mike was in my house for 17 hours.
