You divide 33/11 to get to then 1212/22 to get fifty five fifty firve minus to is fifty three your anser is fifty three
Answer:
The combined mean can be calculated by plugging in our numbers into the formula given: [(57*82)+(23*63)/(57+23)]=76.5
T2-t1=6, t3-t2=-3, t3=-6
t3-t2=-3 becomes
-6-t2=-3
-t2=3
t2=-3
t2-t1=6 becomes
-3-t1=6
-t1=9
t1=-9 degrees
Answer:
The answer is below
Step-by-step explanation:
For the first clock that is 20 minutes faster in a day, that means it is
faster every day. For it to show the correct time, the clock should be 24 hours faster.
Since 1 day = 1/3 hr faster
x days = 24 hr faster
Let x number of days be required to be 24 hr faster. To find x we use the formula:

For the second clock that is 30 minutes slower in a day, that means it is
faster every day. For it to show the correct time, the clock should be 24 hours slower.
Since 1 day = 1/2 hr slower
y days = 24 hr faster
Let x number of days be required to be 24 hr slower. To find x we use the formula:
