A photocopier increased the sides of a square in the ratio 4:5.
Svetach [21]

Answer:

The sides are increased by a percentage of 25%

Step-by-step explanation:

Let

x -----> the length side of the original square

y ----> the length side of the increased square

we have

\frac{x}{y} =\frac{4}{5}

y=\frac{5}{4}x

y=1.25x

the increase is calculated by subtracting x from y

so

y-x=1.25x-x=0.25x

Remember that

0.25=\frac{25}{100}=25\%

therefore

The sides are increased by a percentage of 25%

Lin’s teacher uses a box to store her set of cubes with an edge length of 1/2 inch if the box is completely full how many cubes
Sauron [17]
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 = 1/2 inch
Therefore, volume of the cube = (1/2)3=1/8 inches
Volume of the storage box = 56 cubic inches
Since, number of cubes fitted in the storage box
= 56/1/8
= 56 × 8
= 448 cubes
Therefore, number of cubes fitted in the storage box = 448
