x - boat speed; y - current speed; Path = 336:2 = 168 miles
1) 12 * (x + y) = 168; -> x + y = 14;
2) 14 * (x - y) = 168; -> x - y = 12;
1) x = 14 - y;
2) (14 - y) - y = 12;
14 - 2y = 12;
2y = 2;
y = 1 mph
x = 14 - 1 = 13 mph
Answer:
Boat speed = 13 mph
Current speed = 1 mph
The answer would be $24.55 per oz of gold alloy so rounded up would be $25
Answer:
18 ft
Step-by-step explanation:
Since the triangle is right angled ; we could use trigonometry ;
Using the angle , 40° ; adjacent side, = 14 feets ; hypotenus = x
Cos θ = Adjacent / hypotenus
Cos 40 = 14 / x
0.7660444 = 14 / x
0.7660444x = 14
x = 14 / 0.7660444
x = 18.27
= 18 ( nearest foot)
Answer: $1100
Step-by-step explanation:
The employer contributes, along with Melissa, in the ratio of 1:2
Up to 6% of $55000, therefore 6/100 x 55000 = 3300
Split in the ratio of 1:2, she will contribute 1/3 of 3300 = 1100
and the employer will contribute 2/3 of 3300 = 2200
