Answer:
A = 1413.72 unit²
Step-by-step explanation:
area of a semicircle formula: A = (πr²)/2
To find the area of a semicircle that has a radius of 30 feet, apply r = 30 to the formula A = (πr²)/2:
A = (π30²)/2
A = 1413.72 unit²

60 km
82.5 km
Step-by-step explanation:
Time = t
Speed = s
Distance is given by
[tex]d=s\times t[/tex]
t = 2 hours
s = 30 km/h
[tex]d=30\times 2=60\ \text{km}[/tex]
Distance driven is 60 km.
t = 7 hours
s = 65 km/h
[tex]d=65\times 7=455\ \text{km}[/tex]
Distance driven is 455 km
t = [tex]\dfrac{1}{2}\ \text{hours}=0.5\ \text{hours}[/tex]
s = 46 km/h
[tex]d=46\times 0.5=23\ \text{km}[/tex]
Distance driven is 23 km
t = 45 minutes = [tex]\dfrac{45}{60}=0.75\ \text{hours}[/tex]
s = 80 km/h
[tex]d=80\times 0.75=60\ \text{km}[/tex]
Distance driven is 60 km
t = [tex]1\dfrac{1}{2}\ \text{hours}=1.5\ \text{hours}[/tex]
s = 55 km/h
[tex]d=55\times 1.5=82.5\ \text{km}[/tex]
The distance driven is 82.5 km

A student has a rectangular photograph with side lengths of 5 inches and x inches The area of the rectangle is 33 square inches. The student wants to reduce the size of the photograph so that each side length is of its original length. The photograph will be printed on paper that costs $0.16 per square inch. What will be the cost of the paper needed to print the reduced photograph?
Answer:
1.32
Step-by-step explanation:
total area = 33
33/5 1/2 = 6 . X=6
5 1/2 x 1/2 = 2.75 . 6 x 1/2 = 3
2.75 x 3 = 8.25
new area = 8.25
8.25 x .13 = 1.32

The electronics store is offering 30% off all accessories. If Lisa saves $9.00 buying four charging cords, what was the original price of the cords?
Answer:
Cost of each cord = $7.5
Step-by-step explanation:
Given:
Discount rate = 30% = 0.30
Amount save by Lisa = $9
Number of charger = 4
Find:
Cost of each cord
Computation:
Total cost of 4 charger = Amount save by Lisa[1/Discount rate]
Total cost of 4 charger = 9[1/0.30]
Total cost of 4 charger = $30
Cost of each cord = Total cost of 4 charger / Number of charger
Cost of each cord = $30 / 4
Cost of each cord = $7.5

You have been offered a unique investment opportunity. If you invest $10,000 today, you will receive $500 one year from now, $1,500 two years from now, and $10,000 ten years from now a. What is the NPV of the investment opportunity if the interest rate is 6% por year? Should you take the opportunity? b. What is the NPV of the investment opportunity if the interest rate is 2% per year? Should you take the opportunity? a. What is the NPV of the investment opportunity if the interest rate is 6% per year? The NPV of the investment opportunity at the interest rate is 0% per year is $(Round to the nearest dollar)
The NPV of the investment opportunity at a 6% interest rate is approximately $6,374. Taking into account the timing and value of the cash flows, it is advisable to take the opportunity.
The Net Present Value (NPV) of an investment opportunity calculates the present value of future cash flows discounted at a specific interest rate. Let's calculate the NPV at a 6% interest rate:
Year 1: Receive $500.
Year 2: Receive $1,500.
Year 10: Receive $10,000.
To find the NPV, we need to discount each cash flow back to its present value and sum them up:
NPV = (Cash flow at Year 1 / (1 + Interest rate)^1) + (Cash flow at Year 2 / (1 + Interest rate)^2) + (Cash flow at Year 10 / (1 + Interest rate)^10) - Initial investment
Plugging in the values, we get:
NPV = (500 / (1 + 0.06)^1) + (1500 / (1 + 0.06)^2) + (10000 / (1 + 0.06)^10) - 10000
≈ $6,374
Therefore, at a 6% interest rate, the NPV of the investment opportunity is approximately $6,374. Since the NPV is positive, it indicates that the investment is expected to generate a return greater than the cost of capital. Hence, it is advisable to take the opportunity.
(Note: The calculation for the NPV at 0% interest rate requires all future cash flows to be treated at their face value. Therefore, the NPV at a 0% interest rate would be equal to the sum of all future cash flows, which is $11,000 in this case.)

Testing: Hop 0.55 H:P +0.55 Your sample consists of 96 subjects, with 55 successes. Calculate the test statistic, rounded to 2 decimal places z Check Answer
The test statistic is approximately 0.45.
To calculate the test statistic for testing the null hypothesis H₀:p = 0.55 against the alternative hypothesis H₁:p ≠ 0.55, you can use the formula for the z-test statistic:
z = (p' - p) / √(p(1-p)/n)
where:
p' = sample proportion
p = hypothesized proportion under the null hypothesis
n = sample size
In this case, the sample proportion is p' = 55/96 = 0.5729 (rounded to 4 decimal places), p = 0.55, and n = 96.
Now let's calculate the test statistic:
z = (0.5729 - 0.55) / √(0.55 × (1-0.55) / 96)
z = (0.0229) / √(0.55 × 0.45 / 96)
z = (0.0229) / √(0.2475 / 96)
z = (0.0229) / √0.002578125
z = (0.0229) / 0.050773383
z ≈ 0.4502 (rounded to 4 decimal places)
Therefore, the test statistic is approximately 0.45.

Based on the Baseball camp example covered in the class, let's assume the segment size is 10000, price per participant is $80, frequency is 1, variable cost per person is $5, TFC = $9,000.
Based on the assumption provided above, what percentage of the segment should participate if the program wants to make $1500 profit?
A) about 3.4%
B) about 0.8%
C) about 2.3%
D) about 1.4%
To determine the percentage of the segment that should participate in the baseball camp in order to make a $1500 profit, we need to calculate the breakeven point and then find the corresponding percentage.
The breakeven point is the point where the revenue equals the total cost, resulting in zero profit. In this case, the breakeven point can be calculated by adding the fixed cost (TFC) to the variable cost per person multiplied by the number of participants.
Given that the price per participant is $80 and the variable cost per person is $5, we can set up the equation:
80x - (5x + 9000) = 0
Simplifying the equation, we have:
75x - 9000 = 0
75x = 9000
x ≈ 120
So, the breakeven point is approximately 120 participants.
To calculate the percentage, we need to divide the breakeven point (120) by the segment size (10000) and multiply by 100:
(120/10000) * 100 ≈ 1.2%
Therefore, the percentage of the segment that should participate in the baseball camp to make a $1500 profit is not exactly 1.2%, but it is closest to option D) about 1.4%.
