Apair of jeans that normally sells for 35 dollars is on sale for 20% off. find the sale price of the jeans. the find the total cost of the jeans if the sales tax rate is 6%

29.68

work:

okay so to solve this problem, you wanna start by finding 20% of 35. to start, change 20% into a decimal, 0.20, and multiply by 35.

35 x 0.2 = 7

so, if you are getting 20% off, that means you are getting $7 off, so subtract 7 from 35.

35 - 7 = 28.

okay, so that's the sale price, but we still have to add the tax. convert 6% into a decimal (0.06) and multiply by the total.

28 x .06 = 1.68

lastly, add the sales tax onto the jean price to get the total.

28 + 1.68 = 29.68

i hope this helped and have a great day! if you need any further assistance with this specific question or i made any mistakes, please let me know!

7.9m and 4.3°

step-by-step explanation:

let east be +x and north be +y, x = distance * cos θ, y = distance * sin θ  

for 3.5 south, y = -3.5  

for 8.2, x = 8.2 * cos 30 and y = 8.2 * sin 30  

for 15 west, x = -15  

total x = 8.2 * cos 30 – 15 ≈ -7.9  

total y = -3.5 + 8.2 * sin 30 = 0.6  

magnitude = [(8.2 * cos 30 – 15)^2 + 0.6^2)]^0.5  

the magnitude is approximately 7.9 m  

tan θ = y/x = 0.6/-7.9  

the angle is approximately 4.3˚ north of west
