Step-by-step explanation:

from the table

f(x) = g(x) = 14 when x = 1 , and

 Janet Henderson is a secretary. She works Monday to Friday every week. If she worked a
total of 44.5 hours this week, and her regular pay is $11.46 per hour. What is Janet's
overtime pay?

Answers

Answer:  Janet's overtime pay is: " $ 17. 19 per hour ."
  →  and specifically:  " $ 77.36 " ;
        →  [for the 4.5 hours of overtime pay worked Within the total 44.5 hours Janet worked within the particular Monday to Friday workweek as given within this particular Brainly question/].
__________

Step-by-step explanation:
__________
Note:  Let us assume that up to and including "40 hours within a workweek" is paid as a "base rate of regular pay"—and that any hours worked over "40 hours" count as "overtime hours.."

Furthermore: Let us assume that "overtime pay" is paid at the rate of "time and a half".  This means that any and all hours worked over 40 hours are "overtime hours"—and that these "overtime hours" are paid at the rate at "1.5 times" the rate of the regular hourly rate.
__________

Note: A secretary is typically a job that is paid by the "hour"; as opposed to certain management positions (which are paid by "salary").
→ So, we shall assume that the secretary, "Janet Henderson", is a "hourly worker"—who is "non-exempt" from being paid "overtime."
→ So, first, given:  Janet Henderson worked Monday through Friday for a total of "44.5 hours."
Note: This amount: "44.5 hours" ; is over "40 hours."
            {i.e. " [44.5 hours]  >  [40 hours] ".}.

Note:  Any and all hours Janet earned in excess of 40 hours are considered : "overtime hours."
Now:  Let us calculate the number of "overtime hours":
   → We subtract: "40"; from the actual amount of hours Janet worked [which is "44.5 hours"] ;
    →   " (44.5 − 40) hours " ;
          =  " 4.5 hours " (of overtime worked).
Now, we are given that Janet's regular pay is:  " $ 11.46 per hour."
→  To solve: Find the value of:   " (1.5) * ($ 11.46) " ;
Method 1) Use a calculator:  to get:  " 17. 19 " .
    → The answer is:  " $ 17.19 per hour."

Method 2)
    →  
" 11.46 + [(1/2)* 11.46] " ;

             =  "11.46 + (11.46 /2)" ;  
Note: Let us start by calculating:  "(11.46 / 2)" ; that is:  "(11.46 ÷ 2)" .
Method A) Note:  " 11.46 ÷ 2 = 5.73 " ; → {Using a calculator.}.
Method B)  
Using long division; to get:  "5.73 " ; as follows:

            5.73
      2⟌ 11.46

        - 10    
             1.46
        -    1.4  
             0.06
        -    0.06
             0.00 .

Now:  We can write the expression:  
 →   " 11.46 + [(1/2)* 11.46] " ;  as:
 →     " 11.46 + 5.73 " ; & then calculate (add the values);

to get" 11.46 + 5.73 = " 17. 19 "

So;  Janet's overtime pay is $17.19 per hour.

Other:
To find the specific, exact dollar amount of overtime pay earned for the "4.5 hours" of overtime worked in the particular Monday to Friday workweek as given within the actual question:

→ We multiply this amount—"17.19 dollars"— by the number of overtime hours that Janet worked—"4.5 hours"—as follows:
→  "   [tex]\frac{17.19 dollars}{hr} *\frac{4.5 hr}{1}[/tex]  " ;  
→  The units of "hr" ["hour(s)"] cancel out to: "1 ";  
          →  {since:   ["hr/ hr " = 1 .] } ;
And we have:  
→ " (17.19 dollars * 4.5)  = _?  dollars " ;  Solve for: {the "_?_"  value.}:
Using a caculator:  We get:
   →  77.355 dollars;  ⇒  write as:  $77.355 ;  round to:  " $ 77.36 " .

In a card game, Alex has 2 diamonds 3 spades 4 clubs, and 1 heart. Without being able to see the cards wes is going to pick one of Alex's cards. What is the probability that wes will pick spade or a club

Answers

Answer:

4/10 or 40% chance he picks a spade and 3/10 or 30% he picks a club so in total he would have a 7/10 chance or 70% chance of getting spade or club

Step-by-step explanation:

The probability that Wes will pick a spade or a club from Alex's cards is 0.7 or 70%.

To find the probability that Wes will pick a spade or a club from Alex's cards, we need to determine the total number of spades and clubs in Alex's hand and divide it by the total number of cards.

Total number of spades = 3

Total number of clubs = 4

Total number of cards = 2 (diamonds) + 3 (spades) + 4 (clubs) + 1 (heart) = 10

Therefore, the probability that Wes will pick a spade or a club is:

(Picking spade or club) = (Total number of spades + Total number of clubs) / Total number of cards

= (3 + 4) / 10

= 7 / 10

= 0.7

So, the probability that Wes will pick a spade or a club from Alex's cards is 0.7 or 70%.

3x=180-50

x=150÷3

x=50

Therefore option D is write answer

Answer:

D   (x = 50°)

Step-by-step explanation:

Angles in a triangle add up to 180°.

             ∴ (2x + 5)° + (x - 10)° + 35° = 180°

                    2x + x + 5 - 10 + 35 = 180

                              3x + 30 = 180

                                  3x = 150

Conditional probability is the probability of one event happening, considering a previous event. The formula is:

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]

In which:

P(B|A) is the probability of event B happening, given that A happened.[tex]P(A \cap B)[/tex] is the probability of both A and B happening.P(A) is the probability of A happening.

The key-word is previous, that is, we have to consider a previous event that already happened. Hence, researching the problem on the internet, the correct option is given by:

Defective = 7

The probability that a defective headset is selected is:

P(Defective) = 7/280

Find the vertex of this parabola. y = -2x2 4x 12 a. (-4, 12) b. (-2, 6) c. (3, 6) d. (1, 14)

Answers

We will see that the vertex of the quadratic equation is at (1, 14)

How to find the vertex of a quadratic function?

For a general quadratic:

[tex]y = a*x^2 + b*x + c[/tex]

The x-component of the vertex is at:

[tex]x = -b/2a[/tex]

In this case, we have:

[tex]y = -2x^2 + 4x + 12[/tex]

Then the vertex is at:

[tex]x = -4/(2*-2) = 1[/tex]

To get the y-component of the vertex, we need to evaluate in x = 1.

[tex]y = -2*1^2 + 4*1 + 12 = -2 + 4 + 12 = 14[/tex]

Then we conclude that the vertex is at (1, 14), so the correct option is d.

Two similar spheres have a scale factor of 2:5. What is the ratio of their surface areas?

Answers

Answer:

4:25

Step-by-step explanation:

Sphere surface area = 4 pi r^2  

   now change r to 2.5 r  ( to maintain the 2:5 ratio)

   area2 = 4 pi (2.5 r)^2 =     6.25    *    4 pi r^2

    so ratio of surface areas is  1 : 6.25   = 4:25

If two similar spheres have a scale factor of 2:5. Then the ratio of their surface areas will be 4 / 25.

What is Geometry?

It deals with the size of geometry, region, and density of the different forms both 2D and 3D.

Two similar spheres have a scale factor of 2:5.

Let the r₁ and r₂ be the radius of the spheres. Then we have

r₁ / r₂ = 2 / 5

Then the surface area of the sphere is given as

Surface area = 4πr²

Then the ratio of their surface areas will be

[tex]\rightarrow \dfrac{4\pi r_1^2 }{4\pi r_2^2} = \left (\dfrac{r_1}{r_2} \right )^2[/tex]

Then we have

→ (2 / 5)²

→ 4 / 25
