Answer:
Step-by-step explanation:
Since the height of each bounce is 3/4 of its last peak height we can use a geometric sequence to find the bounce height for any number of bounces.
h=12(3/4)^b
h(5)=12(3/4)^5
h(5)=2.85m
Answer:
Answer is -19
Step-by-step explanation:
-(7) + 2(-6)
-7 - 12
= -19
The rate for 18:4 divided by 2:2 would be 9:2. This is because 18 divided by 2 is 9 and 4 divided by 2 is 2. The unit rate for 9:2 is 4.5:1. This is because you must divide 2 by 2 in order to get 1, and what you do to the second part you must do to the first part. 9 divided by 2 is 4.5.
William is 17 and Charmine is 14
let Charmine's age be x then William is x + 3, then
3x + 2(x + 3 ) = 76
3x + 2x + 6 = 76
5x + 6 = 76 ( subtract 6 from both sides )
5x = 70 ( divide both sides by 5 )
x = 14
Charmine is 14 and William is 14 + 3 = 17
