If Jim missed 6 out of 16 free throws, then he made 10/16 free throws. At the same time Gracia made 4/15 free rows. The common denominator of those fractions (if we simplify 10/16 to 5/8) is 120, so:
Garcia made 4/15 = 32/120 free throws
Jim made 5/8 = 75/120 free throws
We can clearly see that Jim was more than two times better than Garcia.
Let the speed of the water current be v.
total travel time = time to go upstream + time to return downstream to the starting point
Hence, 8 = time in hours = 6 / (4-v) + 6 / (4 +v) = 6*8/(16-v^2)
Hence, 16 - v^2 = 6, or v^2 = 10 or v = √10 miles / hour
I don’t have a pen and paper so I can’t do this. But I can tell you what to do. Use Pythagoras’ Theorem to work it out.
a2 + b2 = c2
The c2 is the hypotenuse squared and the a2 is the other measurement so
(2 x 2) + (b x b) = 100
4 + (b2)= 100
b2 = 96
b = 9.78
Answer = 9.78

Answer:
26, 37, 40, 48
Step-by-step explanation:
Whole numbers between 20 and 50 will have 10s digits in the range 2–5.
When 4 is added to these numbers, we get ...
2+4 = 6
3+4 = 7
4+4 = 8
5+4 = 9
When 4 is subtracted from these numbers, we get ...
2-4 = -2
3 -4 = -1
4 -4 = 0
5 -4 = 1
__
The numbers we can make using the given 10s digits and their corresponding 1s digit(s) are ...
26, 37, 40, 48
__
We note that any number with a 10s digit of 5 and a 1s digit other than 0 will be out of range.
5 3/4 is the mixed number
