Which would be a good estimate the tax on $97.95 if the tax is 9.5

answer: .64

step-by-step explanation

set up the formula for standard deviation for this set of numbers, then simplify

6x = 48

i hope this . 6 cards each and a total of $48. dvide each side by 6 and you will have your answer.

isaiah walks 3 miles due north, turns and then 5 miles due east. how far is he from his starting point?

a^2 + b^2 = c^2

let c = distance from starting point.

(3)^2 + (5)^2 = c^2

9 + 25 = c^2

34 = c^2

sqrt{34} = sqrt{c^2}

sqrt{34} = c

  or  

sin y = 7/q

7 is the opposite side length, q is the hypotenuse

tan y = 7/r

7 is the opposite side length, r is the adjacent side length

using sohcahtoa ^^^^

cos y = adjacent/hypotenuse

cos y = r/q
