First, the item goes on sale for 25% discount which means that the price will now be only 75% of the original price.

Case 1:  Price = ($80)(0.75) = $60

Then, the item is sold for additional discount of 10% which the new price is only 90% of the supposed price. 

Case 2: Price = ($60)(0.90) = $54

Answer: $54

A circle has an area of 225pift2 find the radius of the circle and find the diameter and circumference of the circle
RideAnS [48]

Answer:

  • radius: 15 ft
  • diameter: 30 ft
  • circumference: 30π ft

Step-by-step explanation:

The area is given in terms of the radius as ...

  A = πr^2

so we can find the radius as ...

  r = √(A/π)

For your circle, the radius is ...

  r = √(225π ft^2/π) = 15 ft

The diameter is twice the radius, so is ...

  d = 2r = 2·15 ft = 30 ft

And the circumference is π times the diameter:

  C = πd = π·30 ft = 30π ft

French fries, 11. Baked potato, 12. Pinto beans, 13. Dessert Chocolate cake, 14. Brownies, 15. Ice cream, 16. Apple pie

This is a combination problem requiring a combination solution with the following formula and steps:

C (n, r) =? C (n, r) = ?

n choose r

n (objects) =  16

r (sample) =  5

C (n, r) =? C (n, r) = ?

C (n, r) =C (14,5) C (n, r) =C (16,5)

=16! (5! (16−5)!) =16! (5! (16−5)!)

= 4368

Select the correct answer.<br> Find the value of x.<br> Please answer!!!
olga nikolaevna [1]

C. 64

Rewrite the logarithm:

8=x^.5

Solve by raising both sides of the equation to the power of the inverse (in this case, the inverse of .5, which is 2):

8^2=x^(.5*2)

64=x

Rectangle ABCD has vertices A(–6, –2), B(–3, –2),
Tatiana [17]

Answer:

A. T–4, 3(x, y)

Step-by-step explanation:

We are given that the transformation changes the rectangle ABCD to the rectangle A'B'C'D'.

The changes in the co-ordinates are given by,

A = (-6,-2) = (-6,-2) + (-4,3) = (-10,1)

B = (-3,-2) =  (-3,-2) + (-4,3) = (-7,-1)

C = (-3,-6) = (-3,-6) + (-4,3) = (-7,-3)

D = (-6,-6) = (-6,-6) + (-4,3) = (-10,-3)

So, we see that the rectangle ABCD is transformed by the co-ordinates (-4,3).

That is, it is translated 4 units to the left and 3 units upwards.

Thus, option A is correct.
