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

Find the solution set for this equation:<br> -a2+4a=0<br> (Separate the two values with a comma)
Rashid [163]

\quad \huge \quad \quad \boxed{ \tt \:Answer }

\qquad \tt \rightarrow \: \{ 0,4 \}

____________________________________

\large \tt Solution  \: :

\qquad \tt \rightarrow \: -  {a}^{2}  + 4a = 0

\qquad \tt \rightarrow \: - ( {a}^{2}  - 4a) = 0

\qquad \tt \rightarrow \: {a}^{2}  - 4a = 0

\qquad \tt \rightarrow \:a(a - 4) = 0

The two cases are :

  • a = 0

or

  • a -4 = 0, that leads to a = 4

We can conclude :

\qquad \tt \rightarrow \:solution \: (a)  = \{ 0,4\}

When solving a 2 step inequality, when do you flip the inequality sign, i keep getting these questions wrong, pls help, i mark b
vaieri [72.5K]
You flip the signs when you are dividing by a negative value.
-2x+3>15
-2x>15-3
-2x>12
x<12/-2
x<-6
Now to test this
Try putting x in the original equation when it is -5.
-2(-5)+3>15
10+3>15
13>15
This is false because our answer says x is less than -6.
Now any value less than -6 will work so let's go with -7.
-2(-7)+3>15
14+3>15
17>15
This result is True.
Hope this helps out!
