First, you need to find 25% of 52.60

Convert 25% to decimal:
25% = .25

Find 25% by multiplying its decimal equivalent by the sales price.

.25 x 52.60 = 13.15

Next, subtract that amount from 52.60 to find the new sale price.

52.60 - 13.15 = 39.45

The final price is $39.45

I need help ASAP!!!!
mrs_skeptik [129]

Answer:

Step-by-step explanation:

the shape is made up of 2 circles and one box add the 3 areas up

circle area = \pir^{2}

3.14*4^{2} = 50.24

50.24*2 =100.48

box, box,  pit now  :P  ooh I was thinking formula one racing,  ( i've been watching that lately)  anyway

box = 8*8 = 64

total = 164.48  is that an option? hmm, yes the bottom two choices.. now the perimeter .  the perimeter is made up of the 2 circles

the circumference of a circle is 2\pir

2*\pi*r

2*\pi*4 =25.1327    that's one whole circle , multiplied by 2 , I can see , by math in my head that's about 50.26

sooo

the 3rd choice looks good  :)

Write an equation of the parabola in vertex form. <br><br>No LINKS!!!! ​
marissa [1.9K]

Answer:

  y = -16x² +180

Step-by-step explanation:

The vertex appears to be the high point of the graph, (0, 180). Then the vertex form equation is ...

  y = a(x -0)² +180

The value of 'a' can be found using the other given point. Substituting for x and y, we have ...

  164 = a(1 -0)² +180

  -16 = a

Then the complete simplified vertex form equation is ...

  y = -16x² +180

Let Bea = x
Therefore Andrew = x + 2
Chris = x - 3

Andrew * Chris = 66
(x + 2)(x - 3) = 66 Remove the brackets.
x^2 + 2x  - 3x - 6 = 66
x^2 - x - 6 = 66 Subtract 66 from both sides.
x^2 - x - 72 = 0
(x - 9)(x + 8) = 0
Find the possible values of Bea's age

x - 9 = 0
x = 9 That value works. She can be plus 9 years old.

x + 8 = 0
x = - 8. There's no way she can be - 8 years old
  
So Bea is 9.
