You are shopping for T-Shirts on your favorite site. You choose 3 shirts, and the site
tells you they will cost $15.50 each, and shipping will cost $12.60
The website then suggests you can save some money by buying a 4th shirt, because
the cost per shirt will reduce to $14.00 each, AND shipping will be free.
How much money will you save by buying 4 T-Shirts?
Your answer will be a positive decimal value. You do NOT NEED the $ sign.

Answer:0.3293

Step-by-step explanation:

Answer:

  2)  c)  (x-3)² + (y+2)² = 25

  5)  x^2 +y^2 -8x -16y +54 = 0

  6)  x^2 +y^2 -10x -12y +36 = 0

Step-by-step explanation:

2) The standard form equation for a circle is ...

  (x -h)^2 +(y -k)^2 = r^2

You are given the center: (h, k) = (3, -2) and a point on the circle. So, the equation will be ...

  (x -3)^2 +(y +2)^2 = r^2

Since we know a point on the circle we know that ...

  (7 -3)^2 +(1 +2)^2 = r^2 = 16 +9 = 25

So, the circle's equation is ...

  (x -3)^2 +(y +2)^2 = 25 . . . . . matches choice C

__

5) As in the previous problem, the standard form equation is ...

  (x -4)^2 +(y -8)^2 = (-1-4)^2 +(7-8)^2 = 25+1 = 26

To put this in general form, we need to subtract 26 and eliminate parentheses.

  x^2 -8x +16 +y^2 -16y +64 -26 = 0

  x^2 +y^2 -8x -16y +54 = 0

__

6) A circle tangent to the y-axis will have a radius equal to the x-value of the center point.

  (x -5)^2 +(y -6)^2 = 5^2

  x^2 -10x +25 +y^2 -12y +36 = 25

  x^2 +y^2 -10x -12y +36 = 0

Answer:

a.  -1, 1

b.  2, 7

c.  1, 1

Answer: 1= ( 13 + 4g )

2= ( 4(10) + 13 )

3= ( 13 + 4(10) )

4= ( 53 )

5= ( 21 )

Step-by-step explanation:

The equivalent expression by cumulative property is,

                    [tex]4g+13=13+4g[/tex]

The commutative property states that the numbers on which we operate can be moved or swapped from their position without making any difference to the answer.

                      [tex]a+b=b+a[/tex]

Given expression is,  [tex]4g+13[/tex]

The equivalent expression by cumulative property is,

                    [tex]4g+13=13+4g[/tex]

For [tex]g=10[/tex],    

                    [tex]4(10)+13=13+4(10)\\\\40+13=13+40\\\\53=53[/tex]

Explanation:

Choice A isn't the answer because we don't know anything about the angles, so we can't use the AA (angle angle) Similarity theorem.

Choice B isn't the answer because we don't have info about all three pairs of sides (we only have two pairs of sides).

Choice C isn't the answer in a similar way choice A isn't either. We don't know anything about the angles, so we can't use the "A" in "SAS".

Choice D is the only thing left. It turns out we don't have enough info to be able to determine if the triangles are similar or not.

yes

There was no picture to go off of, but this should be correct anyways!

Answer:

Step-by-step explanation:

et A=120°

and B=5Pi /6

Pi radians ---------> 180°

  x<----------------------- 120°

so x =120 x Pi / 180 = 12 xPi / 18 = 2 Pi/3

so A = 2Pi / 3 radian  

let 's compare A and B

we know that 5Pi /6 = 0.8 Pi and  2P/3= 0.6 Pi, 0.8>0.6,  

finally 5Pi /6 > 2P/3

so B>A

Answer:

  b.  4.4 hours

Step-by-step explanation:

We can use the conversion factor 1 mi/h = 22/15 ft/s. The required relation is ...

  time = distance/speed

  [tex]\dfrac{30\text{ mi}}{\left(\dfrac{150\text{ ft}}{15\text{ s}}\right)}\times\dfrac{\left(\dfrac{22\text{ ft}}{15\text{ s}}\right)}{\left(\dfrac{1\text{ mi}}{1\text{ h}}\right)}=\dfrac{(30)(22)\text{\h}}{150}\text{ h}=4.4\text{ h}[/tex]

Assuming Kyle can keep up the pace for that distance, it would take him 4.4 hours to run 30 miles.

Answer:

4 hours

Step-by-step explanation:

Distance / Velocity = Time

Answer:

whole age of class is 12 + 12 ÷2

= 12

Step-by-step explanation:

Symmetrical functions can be about the x and y axis. Essentially, if we reflect the graph across the y or x axis, we get the same graph. Some other graphs can be reflected across both the x and y axis at the same time and be symmetrical. These can be classified as odd and even functions. You can test this by replacing x and y with -x and -y and simplify the equation. If the results comes out to be the same as the original, it is symmetrical across the origin.

Best of Luck!

Answer:

a shape that has reflective symmetry either x or y axis of origin.

in other words...  it's a mirror image.

Answer:

x = 3

Step-by-step explanation:

12 = 7x + 6 -5x        {Combine like terms}

12 = 7x - 5x + 6

12 = 2x + 6           {Subtract 6 from both sides}

12 - 6 = 2x

      6 = 2x                  {Divide both sides by 2}

Answer:

[tex]GH=2\sqrt{10}[/tex]

Step-by-step explanation:

Considering each is square is 1x1.

We have the points G(-2, -3) and H(0, 3).

Using the distance formula:

[tex]$d=\sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$[/tex]

[tex]$d=\sqrt{(-2 - 0)^2 + (-3 - 3)^2}$[/tex]

[tex]$d=\sqrt{(-2 )^2 + (-6)^2}$[/tex]

[tex]$d=\sqrt{4 +36}$[/tex]

[tex]d=\sqrt{40}=2\sqrt{10}[/tex]

Also, using the Pythagorean theorem:

[tex]a^2+b^2=c^2[/tex]

[tex]2^2+6^2=c^2[/tex]

[tex]4+36=c^2[/tex]

[tex]c=GH=\sqrt{40}=2\sqrt{10}[/tex]

Let the smallest integer equal x - 1, the next one equal x, and the last one equal x + 1.

4(x-1) = 3(x-1) + 6

x-1 = 5

x = 6

The smallest integer is x - 1, which is equal to 5. Thus, the smallest of the three integers is 5.

Answer:

x = 60

Step-by-step explanation:

X/2-5=25

x/2*2 = 30*2

x = 60

Answer:

60

Step-by-step explanation:

x/2 - 5 =25 /×2

x - 10 =50

x=50 +10

x=60
