C would be the correct answer with the given information, because with a constant 6% inflation rate the cost of tuition would total in the given years to $99,511
The two friends will be 150 miles apart, when the sum of the distances covered by the them is 150 miles.
distance = speed x time.
Let the time covered when they are 150 miles apart be x, then:
40x + 35x = 150
75x = 150
x = 150/75 = 2.
Therefore, the two friends will be 150 miles apart in 2 hours.
Given
A rectangular park of length 60 m breadth 50 m encloses with volleyball court of length 18 m and breadth 10 m.
To find:
The area of the park excluding the court at the rate of Rs 110 per square meter.

Area of whole park is:


Area of volleyball court is:


Now, the area of the park excluding the court is:



Therefore, the area of the park excluding the court is 2820 square meter.
The answer is C
(x-h)^2 + (y -k)^2 =r^2
Center (h,k) r = radius
