Step-by-step explanation:
Scientific notation : 6.04 * 10^-5.
We first need to find the distance.
The information about Mike will provide the distance we need to answer the question about Pedro.
We will use D = rt
Mike:
(6.5)((17/5) = D
22.1 miles = D
Pedro:
D = rt
22.1 = (19/5)t
We need to find t.
22.1 ÷ 3.8 = t
5.8157894737 = t
We now round off as instructed.
5.82 = t
It took Pedro 5.82 hours to reach the lake.
A= q over 5c+3
Hope this helps
Answer:
a) yes
b) no
c) no
Step-by-step explanation:
a) The percentage change from 12 to 15 is ...
(15/12 -1)·100% = 1/4·100% = 25% . . . . between 20% and 30%
__
b) The height increased by 61-52 = 9 inches. 20% of 52 inches is 10.4 inches, so the increase was less than 20%.

___
In summary ...
a) yes, 25% is between 20% and 30%
b) no, 17.3% is NOT between 20% and 30%
c) no, -33.3% is NOT between 20% and 30%
_____
A percentage change can be calculated from ...
