Distance = rate (speed) x time
d = (6km/h)(2.33 hrs) (needed to convert 2h 20 mins to hours)
d = 13.98 km
Height of Sandra that is already mentioned in the question is = 4 feet
Percentage by which Pablo is taller than Sandra = 10%
Height by which Pablo is greater than Sandra = (10/100) * 4
= (4/10)
= 0.4 feet
Then height of Pablo is = 4 + 0.4
= 4.4 feet
Now we can find the height of Michaela as she is 8% taller than Pablo.
Percent by which Michaela is taller than Pablo = 8%
Height by which Michaela is greater than Pablo = (8/100) * 4.4
= (2 * 4.4)/25
= 0.35 feet
Then the height of Michaela = (4.4 + 0.35) feet
= 4.75 feet
So height of Michaela is 4.75 feet. This is the way this problem has to be solved.
I believe the answer is $417.91
Answer:
a=7
Step-by-step explanation:
6a-42=-7a+49
(add 7a to 6a)
13a-42=49
(add 42 to 49)
13a=91
(divide 91 by 13)
a=7
