Carl bought a DVD that cost $24.00 plus 8.25% sales tax. How much did Carl pay for this DVD in dollars and cents?
Diano4ka-milaya [45]

Answer: Carl paid $25.98 for this DVD in dollars and cents.

Step-by-step explanation:

The original cost of the DVD was $24.00. If a sales tax of 8.25% was charged, it means that the original cost of the DVD would increase by 8.25%.

The value in dollar and cents of an 8.25% increment(sales tax) would be

8.25/100 × 24 = 0.0825 × 24

= $1.98

Therefore, the amount that Carl would pay for this DVD in dollars and cents is

24 + 1.98 = $25.98

The number 360 has many factors. This may be why it was chosen for the number of degrees in a full turn
shtirl [24]

Answer:

Due to having 24 divisors.

Step-by-step explanation:

360 has many factors which might be the reason it was chosen for the number of degrees in a full turn. There are total 24 divisors of 360 number which make it the highest factors among all numbers. All circles are divided into 360 even parts so that the Sun would move through 1 part each day. Each of these parts was describes 1 degree and this division give us the idea that a circle contains 360 degrees so we can say that this is the reason that 360 is chosen in degrees.

The expression p/x^2 - 5x +6 simplifies to x+4/x-2. Which expression doees p represent?
gladu [14]
We know that
(ad)/(bd)=d/d time a/b=a/b since d's cancel
also
if a/b=c/d in simplest form, then a=c and b=d

we have
p/(x^2-5x+6)=(x+4)/(x-2)
therefor

p/(x^2-5x+6)=d/d times (x+4)/(x-2)
p/(x^2-5x+6)=d(x+4)/d(x-2)

therefor
p=d(x+4) and
x^2-5x+6=d(x-2)

we can solve last one
factor
(x-6)(x+1)=d(x-2)
divide both sides by (x-2)
[(x-6)(x+1)]/(x-2)=d
sub


p=d(x+4)
p=([(x-6)(x+1)]/(x-2))(x+4)
p= \frac {(x-6)(x+1)(x+4)}{(x-2)}
