Answer:
7 feet 10 inches
Step-by-step explanation:
A ball is falling from a height of 30 feet and then it bounces. After each bounce, the maximum height of the ball is 80% of the previous height.
So, after 1st bounce, the maximum height was (0.8 × 30) feet.
Similarly, after 2nd bounce, the maximum height was 0.8(0.8 × 30) feet.
In this way, the maximum height of the ball after nth bounce will be
So, after 6th bounce the maximum height will be feet = 7 feet 10 inches (Appx.)
Answer:
11
Step-by-step explanation:
Put 36 where y is in the expression, then do the arithmetic.
(36 -3)/3 = 33/3 = 11
Answer:
6
Step-by-step explanation:
3х - 5 = 13
+5 +5

/3 /3
x=6
Answer:
The answer is A. The volumes are the same
Step-by-step explanation:
First you have to determine the area of the cross sections for each of them.
The area of the rectangular cross section will be:
A= 7(6)
A= 21 cm²
The area of the triangular cross section will be:
A= (7)(6)
A= 21 cm²
So, they both share the same area which Cavalieri's Principle said that if two solids of equal height have equal cross-sectional area at every level, then the volume are the same.
Answer:
6 units
Step-by-step explanation:
9x - 4 = 2 ( 5x - 5 )
9x - 4 = 10x - 10
10x - 10 = 9x - 4
10x - 9x = - 4 + 10
x = 6
