Answer:

$54.40

Step-by-step explanation:

First, find the new price after the 20% markdown:

80(0.8)

= 64

Then, find the price with the 15% markdown:

64(0.85)

= 54.4

So, the new price of the coat is $54.40

Answer:

y= 9x -4

Step-by-step explanation:

Please see attached picture for full solution.

The integers here are 9 and -4.

There isnt a need to use fractions in this case and hence I did not write the integers into a fraction (e.g. -4 into [tex] \frac{ - 4}{1} [/tex]) since the question requires them to be in the simplest form.

Answer:

x = 6

Step-by-step explanation:

B is the midpoint of AC. So, the length of AB equals length of BC

BC = AB

4x - 4 = 20  {add 4 to both sides}

4x  -4 + 4 = 20 + 4

4x = 24  { divide both sides by 4}

4x /4 = 24/4

x = 6

Step-by-step explanation:

[tex]V=nr^{2}h\\\frac{V}{nh}=\frac{nr^{2}h }{nh}\\\frac{V}{nh}=r^{2}\\\sqrt{\frac{V}{nh} }=\sqrt{r^{2} }\\r=\sqrt{\frac{V}{nh} }[/tex]

Answer:

2 19/24 feet

Step-by-step explanation:

14 5/8 = 14 15/24

17 5/12 = 17 10/24 ==> 16 34/24

16 - 14 = 2

34/24 - 15/24 = 19/24

Answer = 2 19/24 feet

Answer:

w = 19 or w = -13

Step-by-step explanation:

Solve for w over the real numbers:

abs(w - 3) + 8 = 24

Hint: | Isolate terms with w to the left hand side.

Subtract 8 from both sides:

abs(w - 3) = 16

Hint: | Eliminate the absolute value.

Split the equation into two possible cases:

w - 3 = 16 or w - 3 = -16

Hint: | Look at the first equation: Solve for w.

Add 3 to both sides:

w = 19 or w - 3 = -16

Hint: | Look at the second equation: Solve for w.

Add 3 to both sides:

Answer: w = 19 or w = -13

Answer:

PT=19

Step-by-step explanation:

It is given that, T is the midpoint of PQ. If T is mid point, then it will bisect the line segment i.e.

PT=TQ

4x + 7=8x - 5

Subtracting 7 both sides

4x + 7-7=8x - 5-7

4x=8x-12

Subtracting 8x both sides

4x-8x=8x-12-8x

-4x=-12

4x=12

x=3

The value of x is 3.

Now,

PT =  4x + 7

= 4(3) + 7

=12+7

=19

Therefore, the length of PT is 19.

Answer:

Option C.

Step-by-step explanation:

It is given that Stella rewrites −212+3.7 as 3.7−212.

We need to find which property did she use.

According to commutative property of addition,

[tex]A+B=B+A[/tex]

Where, A and B are any real values.

In the given expression −212+3.7, A=-212 and B=3.7.

Using commutative property of addition, we get

[tex](-212)+3.7=3.7+(-212)[/tex]

[tex](-212)+3.7=3.7-212[/tex]

So, she used commutative property.

Therefore, the correct option is C.

Answer:

210 degrees

Step-by-step explanation:

-150 + 360 = 210

The angle between 0° and 360° is 210°

In plane geometry a figure is formed by "two ray or lines and that shares same point is called an angle".

Co terminal are angles in "standard position (angles with initial side along the positive x-axis) they have common terminal side".

According to the question,

The co terminal angle is 150°. The plane is formed by angle between 0° and 360°. In order to find angle is 150° + 360° = 210°.

Hence, the angle between 0° and 360° is 210°.

Answer:$10.50

Step-by-step explanation:

Let t = cost per pound of turkey

Let h = cost per pound of ham

4t + 2h = 30

t = h - 1.5

substitute h-1.5 in place of t in 1st equation

4(h-1.5) + 2h = 30

4h - 6 + 2h = 30

6h - 6 = 30

6h = 36

h = 6

t = h-1.5 = 4.5

1 pound of turkey costs $4.50

1 pound of ham costs    $6.00

                                ----------

cost of 1 pound each  $10.50

Answer:

The bird would have to fly up 685.8 feet up.

Step-by-step explanation

If we are talking about how much the bird wants to fly up to the nest, then it would be 685.8 ft up.

first,

you take the fractions which are (-51 3/10) and (737 1/10)

Then we make them decimals to be easier (on my pov) Then we have

-51.3 and +737.1

Next we add 737.1+(-51.3)

which equals 685.8 feet.

Answer:

374 °F

Step-by-step explanation:

Data obtained from the question include the following:

Temperature (°C) = 190 °C

Temperature (°F) =?

Recall:

The conversion scale of temperature from °F to °C is given by the following equation:

C = 5/9(F – 32)

Next, we shall make F the subject of the formula. This can be obtained as follow:

C = 5/9(F – 32)

Cross multiply

5(F – 32) = 9C

Divide both side by 5

F – 32 = 9C/5

Rearrange

F = 9C/5 + 32

With the above formula, we can convert 190 °C to °F as follow:

Temperature (°C) = 190 °C

Temperature (°F) =?

F = 9C/5 + 32

F = 9 × 190/5 + 32

F = 1710/5 + 32

F = 342 + 32

F = 374 °F

Therefore, Teo will set the oven to 374 °F

Answer:

[tex](\frac{3}{2} , -\frac{5}{4})[/tex]

Answer: They intersect at [tex](\frac{3}{2},-\frac{5}{4} )[/tex]

Step-by-step explanation:

x-2y = 4  

7x  + 2y = 8  

We will solve the equations using the substitution method so we will solve for y in one of the equations and  and substitute it into the other equation to solve for x.

x - 2y = 4  

-x         -x

-2y = 4 - 1x      Divide both sides by -2

y = 1/2 x - 2      Now use substitution

7x + 2( 1/2x -2) = 8  

7x + 1x - 4 = 8  

  8x -4 = 8

       +4   +4

8x = 12

x =  12/8   and simplifies to   3/2  

the value of x is 3/2  so plot it into one  of the equations and solve for y.  

7(3/2) + 2y = 8  

21/2  + 2y = 8

-21/2            -21/2

2y = -5/2  

y = -5/4
