Answer:
2.4
Step-by-step explanation:
- √(x² +49) = x + 5
- (√(x² +49) )²= (x + 5)² ⇒ square of both sides
- x² + 49 = x² + 10x + 25 ⇒ simplifying, x² get cancelled
- 10x = 49 -25
- 10x = 24
- x= 24/10
- x= 2.4
<u>Answer is</u> 2.4

Answer:
0.27
Step-by-step explanation:
Since it's given that the student is dropped off by parents, we can ignore all the students who take the bus, so our total population is 0.45. So now we just take the seventh grade students, 0.12, and divide by the total students whose parents drop them off, 0.45.
0.12/0.45 = 0.266666, round up to 0.27.
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.)
