Answer:
6.25%
Step-by-step explanation:
We first begin by solving for the original price of the cell phone.
if 2400 = 125%
x = 100%
By cross multplying, we get
125x = 2400 * 100
x = 240000/125
x = 1920rs
To find the profit percentage on the new sale price, we repeat another set of equations
100% = 1920
x = 2040
1920x = 2040 * 100
x = 204000/1920
x = 106.25%
His new profit percentage is 6.25%
Answer:
D
Step-by-step explanation:
To convert from polar to rectangular form
• x = rcosΘ , y = rsinΘ
• r = 
⇒ r² = x² + y²
Given
r = 8cosΘ
r = 8 × 
( multiply both sides by r )
r² = 8x, hence
x² + y² = 8x ⇒ D
Answer:
X^2 +x -6 or the last option
Step-by-step explanation:
Answer:
= 56°
= 34°
Step-by-step explanation:
3x + 5 + 2x = 90°
3x + 2x + 5 = 90°
5x + 5 = 90°
5x = 90 - 5
5x = 85
x = 85/5
x = 17
3x + 5
= 3(17) + 5
= 51 + 5
= 56°
2x
= 2(17)
= 34°
