The inscribed angle is half the measure of the intercepted arc:
142°/2 = 71°
Answer:
D. About 2700 in^2
Step-by-step explanation:
The area of a circle A = πd²/4 where d = diameter of circle.
A/d² = π/4 = k the proportionality constant.
So, A₁/d₁² = A₂/d₂² Now for circle A, Area = A₁ = 300 in² and diameter = d₁ = 20 inches. For circle B, Area = A₂ = unknown and diameter = d₂ = 60 inches.
So, we have
A₁/d₁² = A₂/d₂²
A₂ = A₁d₂²/d₁²
A₂ = A₁(d₂/d₁)²
substituting the values of the variables, we have
A₂ = 300 in²(60 in/20 in)²
A₂ = 300 in²(3)²
A₂ = 300 in²(9)
A₂ = 2700 in²
So, the area of circle B is about 2700 in²

5.6 Break – Even Point for a single product
Finding the break-even point
A company breaks even for a given period when sales revenue and costs charged to that period are equal. Thus, the break-even point is that level of operations at which a company realizes no net income or loss.
A company may express a break-even point in dollars of sales revenue or number of units produced or sold. No matter how a company expresses its break-even point, it is still the point of zero income or loss. To illustrate the calculation of a break-even point watch the following video and then we will work with the previous company, Video Productions.
Before we can begin, we need two things from the previous page: Contribution Margin per unit and Contribution Margin RATIO. These formulas are:
Contribution Margin per unit = Sales Price – Variable Cost per Unit
Contribution Margin Ratio = Contribution margin (Sales – Variable Cost)
Sales
Break-even in units
Recall that Video Productions produces DVDs selling for $20 per unit. Fixed costs
Answer:
1: 12 and 48
2: 45 and 15
3: 2 and 58
Step-by-step explanation:
60-12=38
60-15=45
60-2= 58
