Answer:
4.5 mph or 9/2 mph
Step-by-step explanation:
Let x be the rate of the current
Formula: Distance = rate x time
where rate upstream =(12-x) and time =2 hours
15=(12-x)(2)
15=24–2x
2x=24–15
2x= 9
x=9/2=4.5 miles per hour (rate of current)
Answer:
NO.
Step-by-step explanation:
If it is a right triangle then by the Inverse of the Pythagoras Theorem:
40^2 = 35^2 + 15^2
Testing:
40^2 = 1600
35^2 + 15^2 = 1225 + 225 = 1450
So the answer is NO>

Answer:
Area of the circle = 49 π cm² = 153.86cm²
Step-by-step explanation:
Given that the diameter of the circle
d = 14
The radius of the circle
Area of the circle
A = πr²
A = 3.14 ×(7)²
A = 153.86 cm²
