Answer:
<h2> 434</h2>
Step-by-step explanation:
|GI| = 2•16 = 32
|JI| = 28
|GJ|² + |JI|² = |GI|² {Pitagoras}
|GJ|² + 28² = 32²
|GJ|² + 784 = 1024
|GJ|² = 240
|GJ| = √240 = √[16•15] = 4√15
A = |GJ•|JI| = 28•4√15 = 112√15 = 433.7741... ≈ 434
Answer:
$15
Step-by-step explanation:
The original price of the mirror is unknown, so let's call it x.
The discount on the original price is a 20% discount, so it is 20% of x, or 0.2x.
We are told the discount is $3, so 0.2x = 3. Now we solve the equation for x.
0.2x = 3
Divide both sides by 0.2.
x = 3/0.2
x = 15
The regular price is $15.
