14 / √3 mutliply top/bottom by √3
14*√3 / [ √3 *√3] =
(14√3) / 3
Ah....take EP's answer as the correct one......I thought I read that both were saving.....my bad....!!!
20 + 6n = 172 + 4n where n is the number of weeks it will take them to have the same amount
Subtract 4n, 20 from both sides
2n = 152 divide b 2
n = 76 weeks
Just post your problem......we can probably help you......
Take the sine inverse of [ Opposite / Hypotenuse] .....this will give you "A"
The slant height is just the hypotenuse of the right triangle =
sqrt [10^2 + 5^2 ] = sqrt [ 100 + 25 ] = sqrt [125]
Volume of cylinder = pi * r^2 * h = 3.14 * ( 5)^2 * (22) ≈ 1727 in^3
Volume of cone = (1/3) *pi* r^2 * h = (1/3) * 3.14 * (5)^2 * sqrt (12^2 - 5^2) ≈ 285 in^3
Total volume = [1727 + 285] in^3 = 2012 in^3
sqrt [7^2 - 3^2] = sqrt [ 49 - 9] = sqrt [ 40 ]
Using the distance formula :
AB = sqrt [ (5 - -1)^2 + ( 4 - - 1)^2 ] =
sqrt [ 6^2 + 5^2] =
sqrt [36 + 25] =
sqrt [61] ≈ 7.8 units
|Approximate Value − Exact Value| / |Exact Value| x 100%
l 17.3 - 16.7 l / l 16.7 l x 100% = .0359 x 100% = 3.59%
