A prism is filled with 48 cubes with a side length of 1/2 unit. What is the volume of the prism in cubic units? Please I need he
Aleksandr [31]

Answer:

The volume of the prism is 6 unit³

Step-by-step explanation:

In order to calculate the volume of the prism we first need to calculate the volume of each cube. The volume of a cube is given by the formula below:

volume cube = a³

Where a is the length of the side of the cube. So each cube has a volume of:

volume cube = (1/2)³ = 1/8 unit³

Since the cubes are filling the prism, the volume of the prism is the sum of the volume of all the cubes, in this case 48. Since all the cubes are equal, we can multiply the number of cubes by the volume of one cube in order to calculate the volume of the prism. We have:

volume prism = 48*volume cube

volume prism = 48*(1/8) = 6 unit³

AVprozaik [17]

Answer:

Advance ticket costs $25

Same-day ticket costs $20

Step-by-step explanation:

Let x = the price of one the advance ticket.

Let y = the price of one same-day ticket.

The combined cost of one advance ticket and one same-day ticket is $ 45. This means

x + y = 45 - - - - - - 1

For one performance, 30 advance tickets and 20 same-day tickets were sold. The total amount paid for the tickets was $ 1150. This means

30x + 20y = 1150 - - - - - - - - -2

From equation 1, x = 45- y

Put x = 45- y in equation 2

30( 45-y) + 20y = 1150

1350 - 30y + 20y = 1150

-10y = 1150-1350

-10y = -200

y = 200/10 = $20

x = 45-y

x =45-20= $25

Advance ticket costs $25

Same-day ticket costs $20

Melanie bought bags of colored sand that each cost the same. She spent a total of $24. Find three possible costs per bag and the
lukranit [14]

Answer:

Step-by-step explanation:

Factors of 24 are 1,2,3,4,6,8,12,24

Since we are looking for prices as well as quantity, these numbers must go in pairs.

1*24 = option 1

2*12 = option 2

3*8 = option 3

4*6 = option 4

Any of the above 4 pairs can suit the figures. They can even be reversed except option 1 ($1 and 24 bags but not $24 and 1 bag because the question says bags not bag).
