111/2 * 111/4 * 111/8 * 111/16 = 11 15/16
FIRST JAR 300 ml juice 600 ml water
Second jar 360 ml juice 540 water
(300+ 360) / (600+540) = 660 / 1140 = ........
200 cm = 2m
200 x 75 x 50 x 3/4 = ........ cm3
x^2-3x+1 complete the square take 1/2 of the 'x' coefficient , square it and add and subtract it from the equation
x- 3x + 2.25 -2.25 + 1
(x-1.5)2 - 1.25 You can finish this Q .....
7/ ( 1/6 + 1/8) = 24 days
yes, it would..........
60% play wind that means 40% do NOT play wind instr
40% x 130 = .4 x 130 = 52
first line can be re-arranged to y = -5/3 x - 11/3 slope , m , = -5/3
parallel line y = -5/3 x + b sub in the point given
-5 = -5/3 (2) + b
b = - 5/3
y = -5/3 x - 5/3
ingredients summed = final product
.10 * x ml + .15 (50ml - x) = .12 (50 ml) solve for x the amount of 10 %
.1x + + 7.5 - .15x = 6
- .05x = -1.5
x = 30 ml of 10%
50-30 = 20 ml of 15%
