Answer:
<h2>181 440</h2>
Step-by-step explanation:
We have 9 choices for Choosing the first object
8 choices for Choosing the 2nd object
.
.
.
3 choices for Choosing the seventh object
Therefore if we want to choose7 objects without replacement from 9 objects we have : 9×8×7×6×5×4×3 = 181 440
Also ,we can calculate it this way :
9P7 = 181 440
Four Hundred Ninety two thousand Fifty Three.
V=hπr^2
(15π(3.5^2)ft^3)(55/100)(7.5gal/ft^3)≈2381.23 gal (to nearest hundredth of a gallon)
3/5÷1/7 use the recipical
3/5 ÷ 7/1= 21/5
21÷5=4 1/5 I think is your first answer but I could be wrong
7/8 6/7
you must find common denominator.
49/56 - 48/56= 1/56 again I could be wrong
