Answer:

$m\angle BFG =\frac{ (m\widehat {GB} + m\widehat {CD})}{2}$

Step-by-step explanation:

By the property of intersecting chords, we have:

$m\angle BFG =\frac{1}{2} (m\widehat {GB} + m\widehat {CD} )$

$m\angle BFG =\frac{ m\widehat {GB} + m\widehat {CD}}{2}$

An entrepreneur buys some microscopes. Each one cost $200 and resells online for $526. What is the mark-up percentage?

Dafna11 [192]

Answer:

326

Step-by-step explanation:

Given: Microscopes. Each one costs $200 and resells online for $526.

To find: What is the mark-up percentage?

Solution: Simply take the sales price minus the unit cost, and divide that number by the unit cost. Then, multiply by 100 to determine the markup percentage.

$526 - 200 = 326$

Net Profit Margin = 61.98%

Net Profit = $326.00

Profit Percentage = 163.00%

Solve using the quadratic formula. Approximate answers to the nearest tenth.<br> Help

Pepsi [2]

Answer:

x = 2.4 or x = 0.3

Step-by-step explanation:

3x² - 8x + 2 = 0

Quadratic formula

x = {-b ±√b² - 4ac} / 2a

a = 3

b = -8

c = 2

x = {-b ±√b² - 4ac} / 2a

= {-(-8) ±√(-8)² - 4*3*2} / 2*3

= (8 ± √64 - 24) / 6

= (8 ± √40) / 6

= (8 ± 2√10) / 6

= 8/6 ± 2√10/6

= 4/3 ± √10 / 6

x = 4/3 + √10 / 6 or 4/3 - √10 / 6

x = 2.4 or x = 0.3
