attashe74 [19]4 years ago
7 0

Answer:

200 students

Step-by-step explanation:

Since there are 7 buses and 6 of them are full you would multiply 30•6. Then you would multiply 2/3 with 30 to find how many are on the 7th bus, which is 20. So you would add 180 and 20 to get the answer

lord [1]
The lock has 3 different cylinders that can take up to 70 possible numbers. The possible combination of each cylinder would be 70!
The order of cylinder would be important because the password on 1st cylinder can't be used on cylinder 2. The calculation would be:

possible lock combination= 1st cylinder possible combination* 2nd cylinder possible combination * 3rd cylinder possible combination
possible lock combination= 70!*70!*70!

Job A: $15.00 per hour (40 hours a week)​​Job B: $1,375 semi-monthly
blagie [28]

Notes before we start:

Semi-monthly means you get paid twice a week. We will find out the net pay in 2 weeks to see how much pays better.

Explanation:

Job A pays $15 an hour and whoever is working works 40 hours a week. We can multiply to find how much he/she earns in 2 weeks.

15 * 40 * 2 = $1,200

Job B pays $1,375 semi monthly which means that he/she got paid that much money in 2 weeks.

Answer:

Job B pays better.

Best of Luck!

Need explanation 20 points<br> The function f is such that f(x) = 2x - 6<br> Find f^-1(x)
Dvinal [7]

HEYA! <3

Explanation :

<u>GIVEN </u> :

  • f(x) = 2x - 6

<u>TO </u><u>FIND</u><u> </u> :

  • Inverse of f(x) i.e f ^{ - 1} (x)

<u>S</u><u>OLUTION </u> :

FOLLOW THESE THREE STEPS :

  • LET Y = f(x)

\longrightarrow \tt{y = 2x - 6}

\longrightarrow{ \tt{ \: 2x - 6 = y}}

  • MAKE X A SINGLE TERM IN LHS SIDE

\longrightarrow{ \tt{2x = y + 6}}

\longrightarrow{ \tt{x =  \frac{y + 6}{2} }}

  • INTERCHANGE THE VALUE OF X AND Y

\longrightarrow{ \tt{y =  \frac{x + 6}{2} }}

Hence ,

\boxed{ \boxed{ {f}^{ - 1} (x) =   \sf{ \bold{ \frac{x + 6}{2} }}}}

Hope I helped!

Have a wonderful day / night !
