<span>To solve the problem, to 40%
of the total customer should be solve. And this can be solve by muliplting it
by the fraction (0.4). so 140 x 0.4 = 56 customers. Since Trudy has already 60
of her sutomers job ready then she met her target.</span>
672 is the answer to this question
a = amount (in oz) of solution A
b = amount of solution B
The scientist wants a mixture of 110 oz, so
a + b = 110
Solution A consists of 65% salt, so each ounce of solution A contributes 0.65 oz of salt; similarly, each ounce of B contributes 0.9 oz. The mixture is supposed to consist of 75% salt, which amounts to 0.75 * (110 oz) = 82.5 oz of salt. So
0.65 a + 0.9 b = 82.5
Solve for a and b:
b = 110 - a
0.65 a + 0.9 (110 - a) = 82.5
0.65 a + 99 - 0.9 a = 82.5
0.25 a = 16.5
a = 66 ==> b = 44
52=x because x+128=180 and that is a 189 angle
