Answer:
5 1/10
Step-by-step explanation:
Convert all integers to decimals.
6.1
5.4
5 1/10 = 5.1
6 7/10 = 6.7
The smallest number frrom the list is 5.1 or 5 1/10.
The rate of the current is 2.03 mph if the small motorboat travels 8mph in still water. It takes 3 hours longer to travel 44 miles going upstream than it does going downstream.
<h3>What is a quadratic equation?</h3>
Any equation of the form Where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic equation.
Let's suppose the rate of the current = r
The time it takes to go downstream + 4 hours = time to go upstream
As we know the:
Now,
After solving:
After cross multiplication
44(8+r) - 44(8-r) = 3(8+r)(8-r)
88r = 3(64 - r²)
3r² + 88r - 192 = 0
After solving the above quadratic equation, we get:
r = 2.03 or
r=−31.37 (reject as it is negative)
So, the r =2.03 mph
Thus, the rate of the current is 2.03 mph if the small motorboat travels 8mph in still water. It takes 3 hours longer to travel 44 miles going upstream than it does going downstream.

I choose D, maybe yes or no? (-1,5)
To invert just flip the two numbers. So the inverse of 2,5 would be 5,2, and the inverse of 9,-1 would be -1,9, and so on.
Answer:
LM > MK > KL
Step-by-step explanation:
Given: ΔKLM , m∠K = 101° , m∠L = 67°
By definition of a triangle's sum of interior angles, the ∑ΔKLM's interior angles is 180°, ∴ m∠M = 180 - (101 + 67) = 12°
By the usage of law of sines, the opposite side's measurement is contingent with the angle measurement. The smaller the angle measurement, the shorter the opposite side.
Note the angles:
m∠M = 12° ∴ Side LK = shortest
m∠K = 101° ∴ Side ML = longest
m∠L = 67° ∴ Side KM = in between
∴ LK < KM < ML
A) LM > MK > KL is your answer.
