Answer: 36.84

(lmk if this isnt right)

Step-by-step explanation:

To find the perimeter of the rectangle:

3+3+3+3+3+3=18

or

3(6)=18

To find the diameter of the circle:

12-(3+3)

12-6=6

You can combine the 2 half circles to make 1 full circle since they both have the same diameter. Use the circumference formula to solve.

C=πd

Substitute

C=3.14(6)

Multiply

C=18.84

Add the perimeter of the rectangle and the circumference of the circle.

18+18.84=36.84

Solve for z: 11=6|-2z| -5
skad [1K]

Answer:

the roots are {-4/3, 4/3}

Step-by-step explanation:

Begin the solution of 11=6|-2z| -5 by adding 5 to both sides:

11=6|-2z| -5 becomes 16 = 6|-2z|.

Dividing both sides by 12 yields

16/12 = |-z|

There are two cases here:  first, that one in which z is positive and second the one in which z is negative.

If z is positive, 4/3 = -z, and so z = -4/3, and:

If z is negative, 4/3 = z

Thus the roots are {-4/3, 4/3}

how many different license plates can be formed if each plate plate has 5 different digits followed by 1 letter
Elina [12.6K]

This is a fundamental counting principle problem and can be solved by multiplying the number of choices you have for each digit of the license plate.

For the first five digits you can choose from the numbers 0,1,2...,9 or 10 choices.

A we cannot repeat the digits, so, first five digits will be:

10 × 9 × 8 × 7 × 6

Now the next 1 digit will all be letter all being different

There are 26 letters in the alphabet.. for our second digit we have 26 choices,

Here is the whole calculation:

= 10 × 9 × 8 × 7 × 6 × 26

= 786240

Which expression is equivalent to the expression shown below?
posledela
The correct answer is:  [D]: " (-5 \frac{1}{4})x − \frac{1}{2}" .
_________________________________________________________

Explanation:

_________________________________________________________

 " -1/2(-3/2x + 6x + 1) −<span> 3x " ;

=  (-1/2 * -3/2 x) + (-1/2 * 6x) + (-1/2 * 1) </span>− <span>3x ; 


=   [ (-1 *-3) /(2*2)] x + (-3x) + (-1/2) ] </span>− <span>3x ; 

=   [ (3/4)x </span>− 3x − (1/2) ] −<span> 3x ; 

=   </span>(3/4)x − 3x − (1/2) − 3x ; 

= ?? ;   →  Combine the "like terms" ; 

           → "(3/4)x − 3x − 3x " =   ?? ;

                         → "(3/4)x − 3x = "(-9/4)x";

                         → "(-9/4)x − 3x = "(-21/4)x "  =  " (-5 \frac{1}{4})x " ;  

 →  The answer is:  " (-5 \frac{1}{4})x − \frac{1}{2} " ;
