He pew internet and american life project finds that 95% of teenagers (ages 12–17) use the internet and that 81% of online teens use some kind of social media. of online teens who use some kind of social media, 91% have posted a photo of themselves. state: what percent of all teens are online, use social media, and have posted a photo of themselves? plan: express the information we are given in terms of events and their probabilities. if ={the teen is online}, ={the teen uses social media}, and ={the teen has posted a picture of herself}, what are the given probabilities?

the final amount you will pay is $68.04.

the tip is determined by the pre-tax amount, so we calculate the tip based on the original bill, not after we've added sales tax.

to find the tip:

we can divide 54.00 by 100 to get 1% of 54. then we multiply that by 18.

54 / 100 = .54

.54 x 18 = 9.72

tip = 9.72$

to find the tax:

we can divide 54.00 by 100 to get 1% of 54. then we can multiply that by 8 to get 8%.

54 / 100 = .54

.54 x 8 = 4.32

tax= 4.32

now we can add the tip and tax to the bill to get our total.

54 + 9.72 + 4.32 = 68.04

total: $68.04

step-by-step explanation:

38.6°

step-by-step explanation:

resultant is 10 pound

smaller force = 8 pound

angle formed = tan⁻¹(

                        =tan⁻¹(

                          =tan⁻¹(0.8)

                        =38.6°

answer: no

step-by-step explanation: because the big angle will spread away the 2 side that it is on and make the opposite side even longer.
