Answer:
Step-by-step explanation:
(a) 1.56×10^4 = 1.56×10000 = 15,600
(b) There are 3600 seconds in an hour, so Andrew's time was
15600 s/(3600 s/h) = 13/3 h = 4 1/3 h
1/3 hour is 20 minutes, so Evelyn's time of 4:16 is shorter than Andrew's time of 4:20.
The answer is 157 degrees because the line segment is 180 and if <AFB is 23, you take 23 away from 180 and you should get 157. To check, add 157 to 23 or take away 157 from 180.
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.
