Answer:

1.25m

Step-by-step explanation:

s=ut+1/2gt^2

Newton's second law of motion

F=ma

50x10

500N

500/50

g/a=10m/s^2

u=0m/s

s= 1/2gt^2

v=u+gt

5=0+(10t)

5=10t

t=0.5s

s=0.5×10×(0.5)^2

=1.25m

a gold and diamond bracelet sells for $1800 . find the sales tax and the total price if the sales tax rate is 5.5% .
Sergio [31]

Answer:

Sales Tax In Amount =$99

Total amount of purchase = $1899

Step-by-step explanation:

First, let's find sales tax price in amount(dollars)

(Total Amount)*(percentage of tax)/100=Tax in amount

(1800)*(5.5%)/100 = $99

Therefore, the sales tax in amount would equal to $99, which is the same as 5.5%.

Now, let's find the total price of the purchase.

$1800+$99= $1899

So, the total cost of the purchase would equal to $1899.
