Answer:
00:13 mm:ss
Step-by-step explanation:
There are 60 seconds in a minute. This fact can be used to convert the time period(s) to minutes and seconds either before or after you do the subtraction.
<h3>Difference</h3>
It is often convenient to do arithmetic with all of the numbers having the same units. Here, we are given two values in seconds and asked for their difference.
100 s - 87 s = (100 -87) s = 13 s
The difference between the two time periods is 0 minutes and 13 seconds.
<h3>Conversion</h3>
If you like, the numbers can be converted to minutes and seconds before the subtraction. Since there are 60 seconds in a minute, the number of minutes is found by dividing seconds by 60. The remainder is the number of seconds that will be added to the time in minutes:
87 seconds = ⌊87/60⌋ minutes + (87 mod 60) seconds
= 1 minute 27 seconds
100 seconds = ⌊100/60⌋ minutes + (100 mod 60) seconds
= 1 minute 40 seconds
Then the difference is found in the same way we would find a difference involving different variables. (A unit can be treated as though it were a variable.)
(1 min 40 s) -(1 min 27 s) = (1 -1 min) + (40-27 s) = 0 min 13 s
The difference between the two time periods is 0 minutes and 13 seconds.
It is the first one on the left ( 4 divided by 7)
Consider the given decagon of all equal sides.
Given: 
To find: 
Construction: Join a dotted line from point T to P.
Now, 
and 
lies on the straight line. Hence, they form linear pair.
Therefore, 
(equation 1)
Now, consider triangle TBP with two equal sides TB and BP.
By using the property
"Angles opposite to equal sides of an isosceles triangle are equal."
Since TB=BP, therefore the angles opposite to these sides are also equal.
From equation 1,
Now, in triangle TBP,
By using angle sum property, which states
" The sum of measures of all three angles of a triangle is 180 degrees"
So, the measure of angle TBP is 60 degrees.
To find out whether a prime factorization is correct, verify that all the factors are indeed prime. Then multiply the factors. The product should equal 72.

x'= -6 y'= 6 slope=5/6
slope. (x'-x)=y'-y
5/6. (-6-x)=6-y
5/6. -6-x.5/6=6-y
-5-5x/6=6-y
