Calculate sin inverse of .4321, then add 180 degrees
<span>A(x, y) → (x - 3, y + 1)</span>
Answer:
I think <em>t </em>is 72, because the angle looks equal to the known degree, which is 72. And since all the degrees have to add up to 180, 72+72 is 144 and 180-144 is 36. So angle <em>s </em>is 36 degrees.
Answer:
50miles would be acheived if you drove at 40mph for an hour (60 mins) Then look at 26x2=52, so it would be just below 2 gallons
Step-by-step explanation:
We should find the number of possible ways the student can arrange 4CD from total 20 CDs. We should find the number of combinations.
Combination is a way of selecting r items (CDs) from a set (collection) of n items (CDs). The order of selection of the items does not matter in this situation.
In our case: r=4 , n=20
The formula is: C=n!/(n-r)!*r!=20!/16!*4!=20*19*18*17*16!/16!*4!=20*19*18*17/4*3*2=116280/24=4845
