Answer:
Assuming there are no other parts,
the Whole = A + B is the denominator:
Whole = 3 + 9 = 12
Part A = 3 and Part B = 9 are numerators for each fraction.
The fractions are then:
3/12 and 9/12
Meaning:
Part A is 3/12 of the whole
Part B is 9/12 of the whole
Reducing the fractions, it is also true that:
Part A = 1/4 of the whole
Part B = 3/4 of the whole

<h3>
Answer:</h3>
4.25 mph
<h3>
Step-by-step explanation:</h3>
Speed, distance, and time are related by ...
... speed = distance/time
... distance = speed · time
___
If we let x represent the current speed in miles per hour, the number of miles the jet ski goes upstream is ...
... 0.25(60 -x)
The number of miles it drifts downstream is 2 more than that, or ...
... 0.25(60 -x) +2
The speed it drifts downstream is x, and that speed is equal to the distance divided by the time (3.75 hours):
... x = (0.25(60 -x) +2)/3.75
Multiplying by 3.75, we have ...
... 3.75x = 17 - 0.25x
... 4x = 17
... x = 17/4 = 4.25
The rate of the current is 4.25 miles per hour.
Answer:
A) One hundred random students
Step-by-step explanation:
Remember the angles add to 180, so 27 + 27 + x = 180
54 + x = 180
x = 126
The triangle is isosceles.
