[(100-15)/100 * $3]
= $2.55
$5.35 - $2.55
= $2.80 |80% paper|
80/100 = 2.80/x
4/5 = 2.80/x
4x = 14
x = 3.5
Original price of the paper = $3.50
No, the 2 lines can never ever be both parallel and perpendicular if I'm not mistaken. This is because a set of parallel lines will never touch each other at all. However perpendicular lines are two lines that meet up to get an angle of 90. You cannot have two lines that never touch and touch at the same time.
If the tax rate is 8%, we need to find 108% of the price, or 330 times 1.08, which is $356.4
Answer:
x = 6.5
Step-by-step explanation:
By property of intersecting secants outside of circle.
2x dx/dt +2y dy/dt = 0
<span>x dx/dt + y dy/dt = 0 </span>
<span>9*4 + 12 dy/dt = 0 </span>
<span>dy/dt = - 3 ft/sec </span>
