Artificial Christmas trees are regularly priced at $220. If you get a discount of 35%, how much will the tree cost you?

Answer:

31.241

Step-by-step explanation:

x = 6t + 5,   y = 7 − 5t            −1 ≤ t ≤ 3

dx/dt = 6

dy/dt = -5

The arc length of the curve can be calculated below as

L = ∫[tex]\sqrt{(\frac{dx}{dt} )^2 + (\frac{dy}{dt})^2 dt }[/tex]

 = [tex]\int\limits^3_ {-1} \, \sqrt{36 + 25 dt}[/tex]

 = [tex]\sqrt{61} \int\limits^3_ {-1} \, dt[/tex]

 = [tex]\sqrt{61} [3-(-1)][/tex]

= 4[tex]\sqrt{61}[/tex]  = 31.241

Answer:

x = 59/4

Step-by-step explanation:

4x + 9 = 68

Subtract 9 from both sides.

4x + 9 - 9 = 68 - 9

4x = 59

Divide both sides by 4.

4x/4 = 59/4

x = 59/4

Answer:

X=0.75

Step-by-step explanation:

Step 1:

68-9=59

Step 2:

59 divided by 4= 14.75

Step 3:

0.75=3/4

14 3/4=14.75

Solution:

X=0.75

Another way is 59/4=14.75

Answer:

[tex]\huge{ \boxed{ \sf{No}}}[/tex]

✑ Question :

No , it's not a function.

✎ Reason :

This is not a function because one element 11 of set A is associated to elements 9 and 5 of set B.

♨ Explore about function :

↪ Function is a special type of relation. It is the refinement of relation. In a relation from A to B , every element of set A should have only one ( distinct ) image in B to be a function. In other words , if no two different ordered pairs have the same first component , then it is a function.

Hope I helped!

Have a wonderful day ! ツ

Answer:

$4.50

Step-by-step explanation:

$6.75 divided by 1.5 equals $4.50

The price per pound of beef Mrs.Kearns bought is $4.5 per pound.

A unitary method is a mathematical way of obtaining the value of a single unit and then deriving any no. of given units by multiplying it with the single unit.

Given, Mrs.Kearns bought 1.5 pounds of ground beef from Kroger and

she paid a total of $6.75.

Therefore, The cost of per pound can be obtained by dividing the total amount by the total pounds of beef which is,

= 6.75/1.5.

= $4.5 per pound.

Answer:

First number: 20

Second number: 30

Step-by-step explanation:

First#:   x

Second#:   y

Constraints:

   x + y = 50      

   1/4x + 2/3y = 25

Isolate variable y:

   x + y = 50    

  -1/4 (x + y = 50 )

 -1/4x - 1/4y = -12.5

  Add equations the two equations to eliminate x:

    -1/4x - 1/4y = -12.5

     1/4x + 2/3y = 25

  _________________

       5/12y = 12.5

           5y = 150

              y = 30

Substitution to find x:

       x + y = 50  

       x + 30 = 50

              x = 20

First play = 30 yards gained

Second play = 40 yards lost

Third play = 10 yards gained

Total yards Jason has = +30 -40 +10

= +40 -40

Answer: 0

Step-by-step explanation:

30 - 40 + 10

30 - 40 = -10

-10 + 10 = 0

0 is your final answer

x = [tex]1,\frac{1}{2}[/tex]

Step-by-step explanation:

[tex]4|4x-3|-8=-4\\[/tex]

Add 8 to both sides;

4|4x - 3| = 4               4|4x - 3| = -4

Divide both sides by 4;

4x - 3 = 1                   4x - 3 = -1

Add 3 to both sides;

4x = 4                       4x = 2

Divide both sides by 4;

x = 1             x = [tex]\frac{1}{2}[/tex]

Answer:

-3x+1y=-1

or

3x-1y=1

or

by multiplying with 1/3 the first equation we get

-1x+1/3y=-1/3

or from second equation

1x-1/3y=1/3

Step-by-step explanation:

y-y1=m(x-x1)

y1=-7

x1=-2

m=3

so

y-(-7)=3(x-(-2))

y+7=3(x+2)

y+7=3x+6

-3x+y=6-7

-3x+ 1y= -1

Answer:

1

Answer:

Check below for step-by-step guide.

Step-by-step explanation:

a) Recall the formula for area is length times width. You are given both of those values. Width= (5x+2) and length = (4x-1). All you have to do is multiply them. You will get a quadratic!

b) This is just basically a lot of plugging in to the equation: Volume= length x width x height. So let's look at what we have!

It says our volume is 20x^3 + 63x^2+ 7x-6

It says our width is : (5x+2)

It says out length is (4x-1).

So the volume = l x w x h , we just plug in those numbers I listed above :

20x^3 + 63x^2+ 7x-6= (4x-1) (5x+2) (height)

Now remember you already multiplied length times width in problem (a). You can use that expanded quadratic on the right side. Then subtract values and isolate height!

Answer:

Size of V = 95°

Step-by-step explanation:

The total sum of angles in a triangle is 180°

You can find Angles T and V.

2x+3x+5 = 180°-25°

5x+5 = 155°

5x = 155°-5

    = 150°

x = 150°÷5

  = 30°

Angle V = 3×30°+5
