Varies from locality/state/income bracket etc....it is usually expressed as a % of an amount
7% tax on 12 dollars would be 7/100 x 12 = 84 cents
When adding or subtracting fractions, the denominator must be the same
3/4 - 1/2 = 3/4 - 2/2(1/2) = 3/4 -2/4 = 1/4
You'll have to give us context...
Could be a failing grade
Could mean exponent
Could be euler's number?
could mean energy
Original Length = L = 3w original width = w
NEW length = 3w-4 New width = w+1
Perimeter = 2 x L + 2 x w
2 (3w-4) + 2 (w+1) = 66
6w - 8 + 2w + 2 = 66
8w - 6 = 66
8w = 72
w = 9m = ORIGINAL width Original L = 3w = 27m
Just move the decimal point over 5 places to get
630,000.
4.5^(4.5) = 869.87
4.6^(4.6) =1118.62 So 4.6 is closest.
3.5 is the answer
x + sqrt(x^2 -2) = 2 Subtract x from both sides
sqrt(x^2-2) = 2 - x Square both sides
x^2 - 2 = 4 -4x + x^2 Subtract x^2 from both sides
-2 = 4 - 4x
-6 = -4x
6/4 = x = 1 1/2
d= dimes
q= d + 3
10(d) + 25 (d+3) = 285
35d + 75 = 285
35d = 210
d=dimes = 6 q = 3+6 = 9
Are you dealing with VECTORS and want to know the VELOCITY?
If you just want the SPEED it is Distance/Time = (30+15+15 miles) / (1/2 hr) = 60 / 1/2 = 120 MPH
