What is an equation for Gustavo's bicycle cost 171.18 after a sales tax of 8 percent?
We're not sure what the question is.If $171.18 is the total cost including sales tax, then the original price isP = $171.18/1.08If the original number on the price-tag is $171.18 beforesales tax,then the total cost will beCGB = ($171.08) x (1.08)
What is the probability of testing positive for the disease?
The probability isP(you have the disease)*P(the test shows positive when testing someone with the disease) +P(you don't have the disease)*P(the test shows positive when testing someone without the disease).The second category is particularly important if the disease is rare but the probability of a type II error is large.
What would you use to connect 5 local area networks?
Are they located in the same building? If the geographical difference between locations are vast, then a WAN setup is in order. The basic components of a WAN would be routers, satellites, ISP mainframes, transmission media (Fiber Optics backbones, Power lines, network cables etc). The main component of a WAN is definitley a router though.
How to solve a rectangles width if the ratio of lenght to perimeter is 1 to 3?
P = 2L + 2WSince L : P as 1 : 3, we can write P = 3L.Substitute 3L for P into the formula above,P = 2L + 2W3L = 2L + 2WL = 2WL/2 = WSo that W : L as 1 : 2, and W : P as 1 : 6.We can say that the perimeter of this rectangle isP = 3L or P = 6W
What is the perimeter of a regular octagon?
If you know a side length, s, the perimeter is 8 sIf you know the circum radius, r, (the distance from the center to a vertex) , the perimeter isp = 8 r sqrt(2 - sqrt(2)) (approx 6.12 r)If you know the apothem, a, (the distance from the center to the middle of a side),p = 16 a sqrt(2-sqrt(2))/sqrt(sqrt(2)+2) (approx 6.63 a)
