Answer:
$2.69
Step-by-step explanation:
The prices of the 3 books are:
$2.50, $4.95, $6
The total is $2.50 + $4.95 + $6 = $13.45
The sale is 20% off.
20% of $13.45 =
= 0.2 * $13.45
= $2.69
Answer: You will save $2.69.
4!=4*3*2*1=24
11!=11*10*9*8*7*6*5*4*3*2*1=39916800
7!=7*6*5*4*3*2*1=5040

In terms of percentage she would have got 75% correct
SCale factor is ML/DC = 6/4 = 3/2
So multiply AD by 3/2 to find the length of JM . The length would be 3*3/2=9/2
Next find the perimeter of JKML. It would be 2(9/2+6)=21
BC is 6.08, use distance formula to calculate
height is BE and also 6.08
AD is 18.25
A= h((a+b)/2)
=6.08(6.08+18.25)/2)
= 73.96 units^2 is the area
