1.2
Step-by-step explanation:
Hope this helps

<span><span>In order to calculate the initial price of the motorcycle, we use the formula:
Total item price=(Item price*tax rate)+item price.
Rearranging the equation to solve for the
unknown:
Item price=total item price/Tax rate.
Substituting the real values
into the formula:
Item cost=1,437/12.5%. The result of this equation
determines that the original price of the motorcycle (not including tax) is:
$11,496-$1,437=$10,059</span></span>
Answer:
$ 118.80
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 9%/100 = 0.09 per year,
then, solving our equation
I = 660 × 0.09 × 2 = 118.8
I = $ 118.80
The simple interest accumulated
on a principal of $ 660.00
at a rate of 9% per year
for 2 years is $ 118.80.
Answer:
it is only the RATIONAL numbers who can contain that number
let
d1 = 250 mi the distance that Mattie Evans drove
v1 = the speed of Mattie Evans
d2 = 1300 mi the distance the plane traveled
v2 = the speed of the plane
The speed of the plane was 190 mph faster than the speed of the car:
v2 = v1 + 190
since time = distance/speed and they both traveled the same time we have
d1/v1 = d2/v2
250/v1 = 1300/v2 cross multiply
250v2 = 1300v1 divid eboth sides by 50
5v2 = 26v1
by solving the system of equations:
v2 = v1 + 190
5v2 = 26v1
we find
v1 = 45.24 mph
v2 = 235.24 mph
