An item that costs $278.00 is marked 65% off. The store is offering an additional 10% off the discounted price. Sales tax for the item is 4%. What is the final price, including tax?

Answer:

30% is that the answer I'm sure

Answer:

I am assuming c2, is c^2.

3 × (c2 − 8)

=3 ×(3^2-8)

=27-8

=19

If c2 is c*2

Then,

3 × (c2 − 8)

=3×(6-8)

=18-24

=(-6)

Answer:

10

Step-by-step explanation:

The radius is half of the diameter, so 5 * 2 = 10

Answer:

diameter=2×radius=2×5=10units

Answer:

D

Step-by-step explanation:

We are combining like terms So,

Step 1

-5x + 2y + 3x

Step 2

-5x + 2y + 3x  combine like terms

(-5x+3x)+(2y)  Then you simplify

-2x+2y

So therefore, your answer is D

Answer:

The answer is 6.

Step-by-step explanation:

So basically, since we know that 4 x 4 is 16, then all we have to do is multiply 1 1/2 by 4. 1 1/2 times 4 equals 6.

Answer:

6 pages

Step-by-step explanation:

all you have to do is multiply 1 1/2 by 4 if 4x4 =16

if the addition if (X+45)° and (X+105)° equal 180°

due to they are a co- interior angles.

then X+45+X+105 = 180°

2X+150 = 180°

2X = 30

X = 15°

Answer:

12

Step-by-step explanation:

6(x+8.5)=123

=> 6x + 51 = 123

=> 6x = 123 - 51

=> 6x = 72

[tex] = > x = \frac{72}{6} [/tex]

=> x = 12 (Ans)

Answer:

The answer is false or "impossible"

Step-by-step explanation:

Heres why I say this:

If the “average speed” in one hour make the car travel 50km, it means the speed could not be constant. So, it could be 90km/h during the first 30 minutes and 10km/h during the second 30 minutes. If this is the case, for example, in the next 12 minutes after the first hour, the car could be traveled 18km at 90km/h, completing 50 + 18 = 68km. The tricky word “average” makes it impossible to answer. Good try, but no cigar.

B. 2(3)

Step-by-step explanation:

The other 3 all shows decreasing of 2 three times. 2(3) would be increasing.

Answer:

116.6

Step-by-step explanation:

Answer:

116.6

Step-by-step explanation:

To solve this equation you would need to use the pythagorean theorem. The pythagorean theorem is [tex]a^{2} +b^{2}= c^{2}[/tex] where a and b are lengths of the triangle and c is the hypotenuse (the longest side of a triangle) in this case, the short cut.

First, you would substitute values into the equation:

[tex]100^{2}+60^{2}= c^{2}[/tex]

Then, you would multiply out the squares:

[tex]10,000+3600=c^2[/tex]

Add the numbers together:

[tex]13600=c^2[/tex]

Take the square root of both sides to get the answer:

[tex]c=116.619037897[/tex]

Then round to the nearest tenth to get the answer: c=116.6

Answer:

y = -9 (negative 9)

Step-by-step explanation:

7 - 3(-9) =

7 - (-27) =

34

Hope this helped and pls mark brainliest!

Answer:

Explanation:

7 - 3y = 34

Simplify both sides of the equation

7 − 3y = 34

7 + −3y = 34

−3y + 7 = 34

Subtract 7 from both sides

−3y + 7 − 7 = 34 − 7

−3y = 27

Divide both sides by -3

−3y / -3 = 27 / -3

Simplify

y = -9

Answer:

70%

Step-by-step explanation:

1. 1400÷2000 = 0.07

2. move the decimal over 2 spaces for a percentage 0.07 --> 70.0

3. 70.0 = 70%

Answer:

The dimensions that match Alice's rectangle are 7 cm and 8 cm.

Step-by-step explanation:

The perimeter of the rectangle is given by:

[tex] P = 2(a + b) = 30 cm [/tex]    (1)                              

Where a and b are the sides of the rectangle

Also, the area of the rectangle is:

[tex] A = a\times b = 56 cm^{2} [/tex]   (2)

By solving equation (1) for a, we have:

[tex] a = 15 cm - b [/tex]      (3)                      

Now, by entering equation (3) into (2) we can find one side of the rectangle:

[tex] 56 cm^{2} = (15 cm - b)\times b [/tex]          

[tex] b^{2} - 15b + 56 = 0 [/tex]                                                        

Solving the above quadratic equation we have:

b₁ = 7 cm  and b₂ = 8 cm                      

Now, the other side of the rectangle can be calculated with equation (3):

[tex] a = 15 cm - b_{1} = 15 - 7 cm = 8 cm [/tex]                          

or    

[tex] a = 15 cm - b_{2} = 15 - 8 cm = 7 cm [/tex]            

Taking the first solution (b₁) or the second (b₂), we find that the dimensions that match Alice's rectangle are 7 cm and 8 cm.          

Therefore, the dimensions that match Alice's rectangle are 7 cm and 8 cm.

I hope it helps you!                            

Answer:

250

Step-by-step explanation:

-17+n/5=33

n/5=33-(-17)

n/5=33+17

n/5=50

n=50*5

n=250

n=182

Step by Step Explanation:

The equation we would start out with is:

[tex] \frac{ - 17 + n}{5} = 33[/tex]

From here, we need to multiply both sides by 5. This would create an equation of -17+n=165, as we canceled out the 5.

Then, you need to add 17 to both sides to isolate the variable. This would make the equation n=182, our final answer.

It would be a closed circle starting from 3 going to the right.

2. 4x + 1 - 1 >/ -8

4x >/ -8

x >/ -2

It would be an open circle starting from -2 going to the right.

3. -1 </ 2n + 4 - 5

-1 </ 2n -1

0 </ 2n

Undefined.

4. -6 > 5n + 5 + 4

6√3

Step-by-step explanation:

6 is x. side across from right angle (12) is 2x. so 6x2 to get 12. missing side is x√3. so 6√3

Answer:

6√3

Step-by-step explanation:

using the pythagorean theorem you can plug in the numbers to get √(12^2 - 6^2) = √(144-36) = √108 = 6√3.

Answer:

f(0) = 2

Roots are;

-2 and -1

Step-by-step explanation:

F(0) simply refers to the y-values when x = 0

This is the point at which the graph crosses the y-axis

the value here is 2

To

find the roots of f(x) , we simply find the points at which the plot crosses the x-axis

we have this at x = -2 and x = -1

These are what represents the roots of the equation

Answer:

Step-by-step explanation:

Like terms have same variable with same exponent. Combine the like terms.

x + x = 2x  {Just add the coefficient}

x + y + x +y + 30 + 5 = x +x  +  y + y   + 30 + 5

                                 = 2x + 2y + 35
