Good evening ,
<u><em>Answer:</em></u>
<h2>the regular price of the item is $80.</h2>
<u><em>Step-by-step explanation:</em></u>
Let p represent the regular price of the item.
p - p×(40/100) = 48 ⇌ p×(1 - 40/100) = 48 ⇌ p×(100/100 - 40/100) = 48
⇌ p×(60/100) = 48 ⇌ p = (480×100)/60 = 48 000/60 = 80.

<span>The sinusoidal curves are shown in the picture attached.
Note that the two waves have the same amplitude (same "height"), the same wavelength (same distance from one peak to the next one) and therefore the same frequency, but different phase (they start in different points).
When you sum two different sinusoidal curves with the same amplitude and frequency, but different phase you get a sinusoidal wave with the same frequency as the original curves, but a different amplitude and a different phase.
Therefore, the correct answer is
graph B).

Answer:
No solution
Step-by-step explanation:
2x -y =7
y= 2x +3
- Substitute the y value. <em>2x-(2x+3)=7 or 2x -2x-3=7 </em>
- Eliminate opposites <em>2x <u>-2x</u>-3=7 >>>> -3=7</em>
- Answer <em>-3= 7</em> ( false)
Answer:
242 inches²
Step-by-step explanation:
area = (1/2) · (p + q) · h (trapezoid formula)
(1/2)(13+24)(4)= 74
area= bh (rectangle)
(24)(7)= 168
168+74= 242
