VARVARA [1.3K]

Answer:

240 = w (2w − 4) (w − 1)

Step-by-step explanation:

Volume of a rectangular prism is width times length times height.

V = wlh

Given:

V = 240

l = 2w − 4

h = w − 1

Substituting:

240 = w (2w − 4) (w − 1)

Helga [31]

Answer:

The approximate number of employees who completed web analytics training are 245 .

Step-by-step explanation:

Formula

$Percentage = \frac{Part\ value\times 100}{Total\ value}$

As given

A survey of 600 randomly selected employees in Company X found that 150 of them completed web analytics training.

Part value = 150

Total value = 600

Putting in the above formula

$Percentage = \frac{150\times 100}{600}$

$Percentage = \frac{15000}{600}$

Percentage = 25%

Thus this shows that 150 employees who completed web analytics training from 600 employees are 25% .

As given

If there were 980 employees in the company .

Total value = 980

Percentage = 25%

Putting all the values in the formula

$25 = \frac{Part\ value\times 100}{980}$

$Part\ value= \frac{980\times 25}{100}$

$Part\ value= \frac{24500}{100}$

Part value = 245

Therefore the approximate number of employees who completed web analytics training are 245 .

For his exercise today, Manuel plans to both run and swim. Let r be the number of laps he runs and lets be the number of laps he

QveST [7]

Answer:

The Inequality describing the situation is $3r+2s>45$ .

Step-by-step explanation:

Let the number of laps he runs be $'r'$

Let the number of laps he swims be $'s'$

Now Given:

Time required to run each lap = 3 min

Time required to swim each lap = 2 min

Total minutes he need to exercise more than 45

we need to write the Inequality representing the same.

Solution:

Now we can say that;

Time required to run each lap multiplied by the number of laps he runs plus Time required to swim each lap multiplied by the number of laps he swims should be greater than Total minutes he need to exercise.

framing in equation form we get;

$3r+2s>45$

Hence The Inequality describing the situation is $3r+2s>45$ .
