The correct answer is B) $50 per hour. Hope this helps!
Given:
Principal = Rs. 6000
Rate of simple interest = 6% per annum.
Time = 4 years
To find:
The simple interest and amount.
Solution:
Formula for simple interest:

Where, P is principal, r is the rate of interest and t is the number of years.
Putting P=6000, r=6 and t=4, we get



Now,



Therefore, the simple interest is Rs. 7440 and the amount is Rs 7440.
Answer:
By AA similarity
Step-by-step explanation:
We have been given that ABCD is a parallelogram
So, by the property of parallelogram AB ||CD and FD is cutting the line BC
Hence, FD is transverse line. In transverse line alternate angles are equal.
Therefore, ∠AFD=∠EDC (alternate interior angles)
And ∠FAD=∠ECD (opposite angles in parallelogram)
Therefore, by AA similarity △ADF∼△CDE
In the dimension of the frisbee given to be 10.2 inches in diameter, there are three significant figures. All, from 1, 0 and 2. Since these values are all significant, the last digit determines the greatest possible error allowed that is only in the tenths digit. The circumference of the frisbee is calculated through the equation,
C = πD
Substituting,
C = π(10.2 in) ≈ 32.0 in
