Answer:

40 Operators

Step-by-step explanation:

if 10 operators worked on 120 pages for 2 hours

P operators will work on the same pages for 30min

note: 2hrs= 120min

10×120min/120= P × 30/120

  • cross multiply
  • make P subject of the formula

P= 10×120×120/120×30

P = 40 operators

What is the image of point (0,3) for mapping (x,y) (x-2,y-3)
Ann [662]
When it asks for the image, that means what are your new coordinates after doing the rules they give you. In this, the rule is to subtract 2 from your x value and subtract 3 from the y value. So you subtract 2 from 0 and subtract 3 from 3. This will give you the values to use for the x and y of your answer:)

Find the value of x such that l ⊥ m. A) 10.7 B) 16 C) 46 D) 48
dsp73

Answer:

<h3>B. 16°</h3>

Step-by-step explanation:

The diagram lacks the appropriate figure. Find the figure attached. If the line I is perpendicular to m, this means that the sum of the given angles will be equal to 90° as shown;

(3x+5)° + 37° = 90°

open the parenthesis

3x+5 + 37° = 90°

3x+42 = 90

subtract 42 from both sides of the equation

3x+42-42 = 90-42

3x = 48

Divide both sides of the resulting equation by 3;

3x/3 = 48/3

<em>x = 16</em>

<em>Hence the value of x is 16°</em>
