The interior angles must sum to 360
360-91+82-82 = 105
I am quite confused what this problem asks about.
We are given that:
4,000 / 10 is equal to hundred / 10
I believe this problem is asking us how much in hundreds
is 4,000
Therefore the answer is: 40
Such that:
<span>4,000 / 10 = 40 hundreds / 10</span>
Answer:
of a second
Step-by-step explanation:
We can convert each time into fractions.
11.74 is the same thing as 
and 11.69 is the same thing as
.
We know that 11 - 11 = 0, so we can focus on the fractions for now.
Let's subtract
from
.
.
We can now simplify
by dividing both the numerator and denominator by 5.
.
Hope this helped!
