Answer:

1/3 of an hour

Step-by-step explanation:

Because we already have the same common denominator, subtract the numerators to solve:

\frac{5}{3} -\frac{4}{3} = \frac{1}{3}

Isa has 1/3 of an hour left to play video games (20 minutes).

Original price×(1-discount price)=new price or sale price so

Put x in original price...x(1-45/100)=550

So the original price is 1000

Type in true or false statement... Help ASAP please

For test point x = –2, the inequality is true.

For test point x = 0, the inequality is false.

For test point x=\frac{4}{5}, the inequality is true.

For test point x = 2, the inequality is false.

Solution:

Given expression is the inequality.

$\frac{5 x-3}{(x-1)(x+1)} \leq 0

Substitute x = –2 in the inequality.

$\frac{5 (-2)-3}{(-2-1)(-2+1) }=\frac{-13}{(-3)(-1) }

                            $=\frac{-13}{3 }

                            < 0

For test point x = –2, the inequality is true.

Substitute x = 0 in the inequality.

$\frac{5 (0)-3}{(0-1)(0+1) }=\frac{-3}{(-1)(1) }

                      $=3

                      > 0

For test point x = 0, the inequality is false.

Substitute x=\frac{4}{5} in the inequality.

$\frac{5 (\frac{4}{5} )-3}{((\frac{4}{5} )-1)((\frac{4}{5} )+1) }=\frac{1}{(-\frac{1}{5} )(\frac{9}{5} ) }

                            $=\frac{-25}{9 }

                            < 0

For test point x=\frac{4}{5}, the inequality is true.

Substitute x = 2 in the inequality.

$\frac{5 (2)-3}{(2-1)(2+1) }=\frac{7}{(1)(3) }

                      $=\frac{7}{3 }

                      > 0

For test point x = 2, the inequality is false.

Hence,

For test point x = –2, the inequality is true.

For test point x = 0, the inequality is false.

For test point x=\frac{4}{5}, the inequality is true.

For test point x = 2, the inequality is false.

How many cubes with a side length of 3 cm can be placed inside a box with length of 18 cm, width of 6 cm and height of 9 cm?
vodka [1.7K]

Answer:

36 cubes.

Step-by-step explanation:

to find the number of cubes:

first, identify the volume of the box using the formula: LxWxH

18cm x 6cm x 9cm = 972 cm³

next, identify the volume of the cube to be placed:

given: cube with a side length of 3 cm

Thus, volume of the cube is 3³=27cm³

To identify the number of cubes, divide the volume of the box to the volume of the cubes. 972/27 = 36. Thus we need 36 cubes.
