Answer:

26 most years; 27 some years

Step-by-step explanation:

1 day out of 14 is 1/14 of the number of days in a year.

The number of days in a year depends on the year or years you're talking about. In all cases, there are not an integer number of weeks in a year, so days are left over. 365/14 = 26 1/14.

For example, if you're concerned with every other Monday, most years, there will be 26 of them, but every few years there will be 27. Over a period of 800 years, there will be exactly 71 years with 27 days of interest instead of 26. 800 is not divisible by 71, so the spacing will be uneven.

Answer:

Median.

Step-by-step explanation:

Assuming the teacher is not of similar age to the students, their higher age would pull the mean higher than if the teacher were not included, where  the median would not be pulled by this extreme value.

c) 7π cm

The length of an arc (s) is related to its central angle (θ) and the radius of the circle (r) by ...

... s = rθ . . . . . . . . . θ in radians

Here, the central angle measures are given in "grads". There are 400 grads in a circle, so 200 grads in π radians. To convert grads to radians, we multiply the number of grads by π/(200g).

Then the lengths of the arcs are ...

... arc AB = (20 cm)·(50g·(π/(200g))) = 5π cm

... arc BC = (10 cm)·(40g·(π/(200g))) = 2π cm

E = arc AB + arc BC = 5π cm + 2π cm = 7π cm

Answer:

f=0.02b

Step-by-step explanation:

So we want to figure out the fee (f) therefore our answer will be in terms of f=(something).  Now since the fee is 2% and 2% is decimals is 2÷100=0.02  then:

f=0.02b

Meaning that the fee is 2% of the balance (b).

Answer:

D. $5.37

Step-by-step explanation:

We need to figure out how much grapes cost per pound

Change the mixed number to an improper fraction

7 1/5 = (5*7+1) /5 = 36/5

$12.89 / 36/5

Copy dot flip

12.89 * 5/36 = 1.79 per lb

If we are purchasing 3 pounds, we will multiply by 3

3 lbs * $1.79 / lb = $5.37

Answer:

$13

Step-by-step explanation:

$26,555 ÷ 36 = 737.6388889 ≈ $738 per month

36 × 738 = $26,568

= $13

Answer:

$13 will be overpaid after 36 months if payments are rounded of to nearest whole number dollar.

Step-by-step explanation:

We are given the following in the question:

Total cost of car = $26,555

Number of equal installments made = 36

Payment of 1 installment =

[tex]\displaystyle\frac{\text{Toatl cost}}{\text{Number of installments}} = \frac{26555}{36} = 737.6389\$[/tex]

Rounding of to nearest whole number, payment of one installment =  $738

Value of 36 installments of $738 each =

[tex]36\times 738 = 26568\$[/tex]

Money overpaid after 6 months =

[tex]26568 - 26555 = 13\$[/tex]

Thus, $13 will be overpaid after 36 months if payments are rounded of to nearest whole number dollar.

So with this system of equations, I will be using the elimination method. With the two equations, add them together and you will get:

[tex]2x=6[/tex]

Since the y-variable has been eliminated, we can solve for x. With this, divide both sides by 2:

[tex]x=3[/tex]

Now that we know the value of x, substitute it into either equation to solve for y:

[tex]3+y=2\\y=-1\\\\3-y=4\\-y=1\\y=-1[/tex]

In (x,y) form, your answer is (3,-1).

Answer:

x=3, y=-1

Step-by-step explanation:

x+y = 2  

x -y =4  

I will use elimination to eliminate the variable y.  Add the two equations together.

x+y = 2  

x -y =4  

-------------

2x = 6

Divide each side by 2

2x/2 = 6/2

x = 3

But we still don't know y

x+y =2

Substitute x=3 into the equation

3+y =2

Subtract 3 from each side

3-3 +y =2-3

y =-1

Answer:

f(x) and g(x) have the same x-intercepts (is not true)

Step-by-step explanation:

g(x) is a reflection across the y-axis and a horizontal compression of f(x). In general those transformations will move the x-intercepts. (The y-intercept and the number of x-intercepts will remain unchanged.)

Comment on the question/answer

f(x) = x^3 is a 3rd degree polynomial. When transformed to g(x) = -8x^2, its only x-intercept (x=0) remains the same. The answer above will not apply in any instance where the only x-intercept is on the line of reflection. (The question is flawed in that it does not make any exception for such functions.)

Step-by-step explanation:

The simplified form is [tex]t^{6}[/tex].

Related to "simplification" troubles are a few "solving" issues. just as some expressions contain parentheticals and even nested grouping symbols, so also do a few equations. The simplification manner is equal, whether or not we are running with expressions (and for this reason best simplifying) or equations (so we're additionally fixing).

Like terms: terms which have equal variable elements (identical variable(s) and same exponent(s)). Whilst simplifying using addition and subtraction, you combine “like terms” through retaining the "like term" and including or subtracting the numerical coefficients.

Answer:

14z + 16 is your perimeter

Step-by-step explanation:

To solve the perimeter, add all sides together. Note that in a rectangle, the opposite sides are congruent and parallel to each other.

Let Perimter = p

p = 2(4z + 3) + 2(3z + 5)

Simplify. Distribute the numbers.

2(4z + 3) = 8z + 6

2(3z + 5) = 6z + 10

Simplify. Combine like terms

p = 8z + 6 + 6z + 10

p = 14z + 16

Answer:     " 1 lb ,  14 oz. " .

_________________________________________________

Step-by-step explanation:

_________________________________________________

Note the exact conversion:    " 16 oz.  =   1 lb.  " .

→  {that is:  " 16 ounces  =  1 pound " .}.

_________________________________________________

  30 oz. * ( 1 lb / 16 oz). =  [tex]\frac{30}{16}[/tex]  lbs. ;

                                      = (30/2) / (16/2)   lbs.

                                      =  (15 / 8) lbs.  ;

8 ┌ 15

    -  8                            

        7  ;

The answer is equal to:  " 1  7/8  lbs. " .  

           →   (1 lb)  + (7/8) (lb).  ;

______________________

 →  (7/8) lb.   =  how many "oz." ??

_______________________

Note the exact conversion:   " 1 lb.   =   16 oz.  " .

_______________________

 →   [tex]\frac{7 lb}{8}[/tex] * [tex]\frac{16 oz}{1 lb}[/tex]  ;

                    =  [tex]\frac{7}{8} * \frac{16}{1}[/tex]  oz.   ;

 →  The "8" cancels to a "1" ; and the "16" cancels to a "2" ;

                   →  {since:  " {16 ÷ 8 = 2 } " ;  

             and:   {since:  " {8 ÷ 8 = 1 } " .

_______________________________________________

 →  So we can rewrite as:  

_______________________________________________                  

                  →  [tex]\frac{7}{1} *  \frac{2}{1}[/tex]  oz. ;

                         =  { 7  *  2 }  oz.  ;

                         =   14  oz.

_______________________________________________

→  So:        

_______________________________________________  

 →   " 30 oz. "  =  " (1 lb)  + (7/8) lb.  "  ;

                        =  "  1 lb. + 14 oz. "  ;

                        =  " 1 lb ,  14 oz. " .

_______________________________________________

        →  The answer is:  " 1 lb ,  14 oz. " .

Step-by-step explanation:

The cosine is (adjacent side to angle) / (hypotenuse)

so the cosine of x = 5/16

to get x you multiply cosine by its inverse

(cos^-1 x)(cos x) = (cos^-1 x)(5/16)

= 71.79 degrees

.... ∠KML = (180° -48°)/2 = 66°

ΔKJM is also isosceles, so base angle JMK will be the same measure as ∠JKM, 30°.

∠JML = ∠JMK + ∠KML = 30° +66°

∠JML = 96°

Answer:

D) y = -4x + 5

Step-by-step explanation:

We know a point and a slope.  The point is a special point.  It is the y intercept because x = 0.  We can use the equation for a line in slope intercept form

y= mx+b

where m is the slope  = -4

and b is the y intercept = 5

y = -4x+5

The equation of the line that crosses the y-axis at the point (0,5) and has a slope of -4 is y = -4x + 5. This is found by using the formula of the slope-intercept form of a line, substituting -4 for the slope and 5 for the y-intercept.

To find the equation of the line which crosses the y-axis at the point (0,5) and has a slope of -4, we need to use the formula of slope-intercept form of a line, which is y = mx + b, where m is the slope and b is the y-intercept.

The slope, m, is given as -4. The y-intercept, b, is where x=0, thus is the y-value of the line where it crosses the y-axis. The point provided (0,5) indicates that b=5.

By substituting the slope and y-intercept into the equation, we get y = -4x + 5. So, the equation of the line is y = -4x + 5. Consequently, the correct answer is D) y = -4x + 5.
