I WILL MARK BRAINLIEST WHAT DOES THIS MEAN????
bogdanovich [222]

Answer:

The answers are: 1 and 1.

Step-by-step explanation:

I believe they are how combinations are written. In other words:

_{n}C_{r}=(\frac{n}{r})=n!/(r!(n-r)!) (Ignore the fraction bar, I can't really format it properly).

Anyways, simply find the combination of each:

(\frac{9}{0})=9!/(0!(9-0)!)=9!/9!=1

(\frac{9}{9} )=9!/(9!(9-9)!)=9!/9!(0!)=9!/9!=1

Note that 0! equals 1.

$1799.91 with 6% tax added
anastassius [24]
To find tax : $1,799.91 x 1.06 = $1907.9046. Because it's money, it should be rounded to $1907.90.

Of course, another way to do it is by multiplying $1,799.91 by 0.06, and adding the product that you get to 1,799.91.

Either way, you will still get $1907.9046
