Two clocks are set at 6 A.M. One clock gains 30 seconds every hour and the second clock
loses 1 minute every hour. At what time will the faster clock be 30 minutes ahead of the
second clock?
Answers
Difference in time of both the clocks after 1 minute will be the sum of gain in time of one clock and delay in time of the second clock in 1 minute.
First clock will be 30 minutes ahead of the second clock in 20 hours.
It's given in the question,
Both the clocks are set at 6 A.M.First clock gains 30 seconds every hourSince, 1 second = [tex]\frac{1}{60}[/tex] minutes
Therefore, 30 seconds = [tex]\frac{30}{60}[/tex] minutes
= 0.5 minutes
That means first clocks gains 0.5 minutes in every hour.
Second clock loses 1 minute every hourTherefore, difference in both the clocks in every hour = 1 + 0.5
= 1.5 minutes
Difference of 30 minutes will be in the duration = [tex]\frac{30}{1.5}[/tex] hours
= 20 hours
First clock will be 30 minutes ahead of the second clock in 20 hours.

the object is dropped from the height of 100 m.reached to ground in 10 seconds. find the acceleration of falling object.
Answers
======================================================
Work Shown:
The given values are
vi = 0 = initial velocity (meters per second)d = 100 = distance traveled (in meters)t = 10 = time in secondsPlug those items into the equation below. Solve for 'a'
d = vi*t + (1/2)*a*t^2
100 = 0*10 + (1/2)*a*10^2
100 = 0 + 50a
100 = 50a
50a = 100
a = 100/50
a = 2
The object is falling with an acceleration of 2 m/s^2
This is far below the acceleration of gravity on earth (which is roughly 9.81 m/s^2), so perhaps this object is being dropped on a smaller planet.

Answer:

Step-by-step explanation:
You can see from the first and last points that the data set demonstrates a slight upward trend. That means the slope of the regression line will be near +1, eliminating all choices except A and E.
The y-intercept of such a line will not be negative, eliminating choice A, leaving choice E as the only reasonable option.

4 thousands divided by 10 equals blank hundreds
Answers
Answer:
40 hundred
Step-by-step explanation:
it is 40 hundred because if you do 4000 divided by 10 you will just need to minus a zero at the end which will become 400.
4 thousand divided by 10 equals 4 hundred.
Given,
4 thousand divided by 10 = _______ hundreds.
We need to fill in the blanks.
We need to know the multiplication of 10 and how to convert 4 thousand into a number.
What are the multiples of 10?10 x 1 = 10
10 x 2 = 20
10 x 3 = 30
10 x 4 = 40
10 x 5 = 50
10 x 6 = 60
10 x 7 = 70
10 x 8 = 80
10 x 9 = 90
10 x 10 = 100.
4 thousand can be written as 4000.
We need to divide 4000 by 10.
4000 ÷ 10
4000 / 10
400
We have 4 hundred.
Thus, 4 thousand divided by 10 equals 4 hundred.
