Answer:
28.26 
Step-by-step explanation:
The area of the quarter circle is the area of the circle / 4. Thus, the area is 
= 
= 28.26 square centimeters
Answer:
0.02275
Step-by-step explanation:
We use this z score formula to solve for this question
z-score is is z = (x-μ)/σ/√n
where x is the raw score
μ is the population mean
σ is the population standard deviation
From the above question,
x = 77
μ = 75
σ = 7
number of samples = 49
Hence, the z score = 77 - 75/ (7/√49)
= 2/(7/7)
= 2/1
= 2
Hence, the z score = 2
Using the z table to find probability
P(x<77) = 0.97725
P(x>77) = 1 - P(x<77)
= 1 - 0.97725
= 0.02275
Therefore, the probability that the same mean will be larger than 77 years
is 0.02275
We are required to find the percent of an acres is this lot
The percent of acres of the lot is 27.55%
Area of an acre = 4840 square yards
Area of the lot = Length × width
= 40 feet × 100 feet
= 4000 square feet
<em>convert feet to yards</em>
1 foot = 0.333333
4000 square feet = 1333.333 square yards
Therefore,
Area of the lot = 1333.333 square yards
percent of an acres is this lot = 1333.333 / 4840 × 100
= 0.2754820247933 × 100
= 27.548202479338
Approximately,
27.55%
Therefore,
The percent of acres of the lot is 27.55%

For this case we can make the following rule of three:
9 1/2 m --------------> 28 1/2 rupees
26 1/3 m -------------> x
From here, we clear the value of x.
We have then:
Rewriting we have:
