Geometry help needed!

Mathematics
1 answer:
lilavasa [31]3 years ago
4 0

Answer:

13.76

Step-by-step explanation:

Area of the whole

The area of the whole = s^2 (the firgure is a square

s = 8

Area of the whole = 8^2 = 64

Area of the unshaded part

The 2 half circles = 1 whole circle

The radius of the 1/2 circle = 4 (eight has been cut in half)

Area of two half circles = 2* (pi r^2/2)

Area of two half circles = 2 * (pi 4^2/2)

area of two half circles =  16*pi

Area of the shaded area

Area of the shaded area = area of the whole - area of the unshaded area

Area of the shaded area = 64 - 16*pi

Area of the shaded area = 64 - 3.14*16 = 13.76

The weekly demand for an item in a retail store follows a uniform distribution over the range 70 to 83. What would be the weekly
Xelga [282]

Answer:

Weekly demand will be 76.5

Step-by-step explanation:

Let X denote the weekly demand for an item

We have given that X follows a uniform distribution with a = 70 and b = 83

So f(X)=\frac{1}{83-70}=\frac{1}{13}

Now we need to find x_0 such that P(X\leq x_0)=0.5

\oint_{70}^{x_0}f(x)dx=0.5

\oint_{70}^{x_0}\frac{1}{13}dx=0.5

\frac{x_0-70}{13}=0.5

x_0=76.5

So weekly demand will be 76.5

Mr. Ahmed sold his motorcycle to Mr. Saad at a loss of 28%. Mr.Saad spent Rs.1680 on its repairs and sold the motorcycle to Mr.
belka [17]

Answer:

Rs. 42000

Step-by-step explanation:

Let us assume that Mr. Ahmed bought the bicycle for Rs. x, and sold it for Rs. y to Mr. Saad. Since he made a loss of 28%, hence:

y = x - 0.28x = 0.72x

Mr. Saad spent Rs.1680 on its repairs, therefore the total cost price of the motorcycle = 0.72x + 1680

He then sold it for Rs.35910 making a profit of 12.5%. Therefore:

0.72x + 1680 + [0.125(0.72x + 1680)] = 35910

0.81x + 1890 = 35910

0.81x = 34020

x = Rs. 42000

Therefore the cost price of the motorcycle for Mr. Ahmed is Rs. 42000
