Answer:
First, converting R percent to r a decimal
r = R/100 = 5.5%/100 = 0.055 per year.
Putting time into years for simplicity,
6 months / 12 months/year = 0.5 years.
Solving our equation:
A = 200(1 + (0.055 × 0.5)) = 205.5
A = $205.50
Step-by-step explanation:
The area of the target that earns at least 30 points on a throw is 379.94 square inches
<h3>How to determine the area?</h3>
The target areas that earn at least 30 points on a throw are:
30-point, 40-point and 50-point
From the question, we have:
- Radius 50-point = 3
- Width 40-point = 4
- Width 30-point = 4
So, the total radius is:
r = 3 + 4 + 4
Evaluate the sum
r = 11
The area is then calculated as:
A = πr²
This gives
A = 3.14 * 11²
Evaluate
A = 379.94
Hence, the area of the target that earns at least 30 points on a throw is 379.94 square inches

Answer:
the equation of this line is x = -5
Step-by-step explanation:
Answer: The answer is the first option.
Step-by-step explanation:
Increasing the length by 10% means we multiply the old length x by 1.1 since
100% + 10% = 1+0.1 = 1.1
Old length = x
New length = 1.1x
Old area = x*x = x^2
New area = (1.1x)*(1.1x) = (1.1*1.1)*(x*x) = 1.21x^2
So the area increases by 21%
1.21 = 1+0.21 = 100% + 21%
