Answer:
14.46ft
Step-by-step explanation:
this would be solved using Pythagoras
The Pythagoras theorem : a² + b² = c²
where a = length
b = base
c = hypotenuse
15^2 - 4^2
225 - 16 = 209
the square root = 14.46
Answer:
$24
Step-by-step explanation:
Since 25% is off the price of the shirt, she bought the shirt at 75% of it's cost price. This difference between the full cost and the 75% is what she saved (i.e. 25% was the savings)
So, if the shirt costs x dollars:
$6 = 25% of x
= ( 25/100)*X = 0.25X
X = $6/0.25 = $6x4
X = $24
Smallest possible perimeter is 24, side lengths at 6 units each.
Hey!
We can check which would give us a better price by calculating each final price after the discount has been added:
Option A):
$899 - $150 = $749
Option A) will cost $749.
Option B)
$899 × 0.25 = $224.75
$899 - $224.75 = $674.25
Option B) will cost $674.25
Option C)
$899 - $75 = $824
$824 × 0.15 = $123.6
$824 - $123.6 = $700.4
Option C) will cost $700.4
Option D)
$899 - $50 = $849
$849 × 0.20 = $169.8
$849 - $169.8 = 679.2
Option D) will cost $679.2
So, Coupon B) $674.25 is the best deal for the computer.
