Answer: 15.7 minutes
Step-by-step explanation:
Let x be the time in the beginning (in minutes).
Given: The track team is trying to reduce their time for a relay race.
First they reduce their time by 2.1 minutes.
Then they are able to reduce that time by 10
If their final time is 3.96 minutes, then
x-t1-t2= 3.6
x= 3.6+ t1+ t2
x= 3.6+ 2.1+ 10
x= 15.7
Hence, their beginning time was 15.7 minutes.
In order to solve, you must multiply the original price of the sneakers by the sales tax (in decimal form). So,
$65.95 x 0.0825 = $5.440875 < this is the amount of tax. Add this to the original price to find the total.
$65.95 + $5.440875 = $71.390875, which rounds to $71.39 with tax.
The correct answer is 12
12 x 600 = 7200
solution:
vector N points to the left and up so the components Nx and Ny are negative and positive respectively
then
,
Nx = - N sinθ and Ny = N cosθ
