Answer: x\in (0,1)\cup (4,\infty)

Step-by-step explanation:

Given

In equality is x^3+4x>5x^2

Taking terms one side

\Rightarrow x^3-5x^2+4x>0\\\Rightarrow x(x^2-5x+4)>0\\\Rightarrow x(x^2-4x-x+4)>0\\\Rightarrow x(x-4)(x-1)>0\\\Rightarrow (x-0)(x-1)(x-4)>0

Using wavy curve method

x\in (0,1)\cup (4,\infty)

A pack of cards is numbered 1 to 24. A card is chosen at random. Find the probability that the number on the card is divisible b
serious [3.7K]

Answer:

Step-by-step explanation:

It's simple. So the only cards which are divisible by 2 or 3 are: 2,3,4,6,8,9,10,12,14,15,16,18,20,21,22,24. The formula of probability is P= m/n. Where m-Number of ways it can happen and n- Total number of outcomes.

Our answer is P= 16/24=2/3=66,66%

How many cubes with side lengths of 1/2 cm does it take to fill up the prism
ELEN [110]

24 cubes can filled up the prism

Solution:

The image of the question is attached below.

Given data:

Length of the prism = 2 cm

Breadth of the prism = 1 cm

Height of the prism = $\frac{3}{2} cm

Volume of the prism = length × breadth × height

                                   $=2\times 1\times \frac{3}{2}

                                   =3 cubic cm

Volume of the prism = 3 cubic cm

Side length of the cube = $\frac{1}{2} cm

Volume of the cube = side × side × side

                                 $=\left(\frac{1}{2}\right)^{3}

                                 $=\frac{1}{8} cubic cm

Volume of the cube =  \frac{1}{8} cm

$\text{Number of cubes} =\frac{\text{Volume of the prism}}{\text{Volume of the cube}}

                          $=\frac{3}{\frac{1}{8} }

                          =3\times8

                          =24

Number of cubes = 24

Hence 24 cubes can filled up the prism.

A biker cycles 9 miles in 2 3 of an hour.
Aloiza [94]

Answer:

2 hours: 27 miles, 3 hours: 40.5 miles, 3.5 hours: 47.25 miles

Step-by-step explanation:

1.) If a hiker hikes 9 miles in 2/3 of an hour, he will hike 4.5 (Half of 2/3 is 1/3 and half of 9 is 4.5) miles in 1/3 of an hour and 13.5 miles per hour. (1/3 times 3 gives us a whole and 4.5 times 3 is 13.5)

2.) 2 hours: 13.5 * 2 = 27 miles

3.) 3 hours: 13.5 * 3 = 40.5 miles

4.) 3.5 hours: 13.5 * 3.5 = 47.25 miles
