Answer:
15.81 = ?
Step-by-step explanation:
Since this is a right triangle we can use the Pythagorean theorem
a^2+b^2 = c^2 where a and b are the legs and c is the hypotenuse
9^2 + 13^2 = ?^2
81 +169 = ?^2
250 = ?^2
Taking the square root of each side
sqrt(250) =?
15.8113883= ?
To the nearest 100th
15.81 = ?
~Subtract 12 from both sides
3/4x + 12 − 12 = 24 − 12
~Simplify
3/4x = 12
~Multiply both sides by 4/3
3/4 * 4/3 = 12 * 4/3
~Simplify
x = 16
Hence, the correct answer is [ b. 16 ]
Best of Luck!

Answer:
- boat: 16 mph
- current: 4 mph
Step-by-step explanation:
speed = distance / time
The rate downriver is (60 mi)/(3 h) = 20 mi/h.
The rate upriver is (60 mi)/(5 h) = 12 mi/h.
The rate of the boat in still water is the average of these:
(20 +12)/2 mi/h = 16 mi/h
The rate of the current is the difference between the boat speed and actual speed:
16 mi/h - 12 mi/h = 4 mi/h
Move all terms that don't contain c to the right side and solve.
Answer: c = 0
