Answer:
v = 120
Step-by-step explanation:
If v is inversely proportional to square root of d, then we can write
= k
If v = 30 and d = 400, then
30() = k
k = 30(20) = 600
Now = 600
If d = 25, then v = 600
5v = 600
v = 120
Answer:
e
no, the numbers are not pythagoras triple
Step-by-step explanation:
find the complete question in the attached image
If the angle is a right angle would be determined using Pythagoras theorem
The Pythagoras theorem : a² + b² = c²
where a = length
b = base
c = hypotenuse
20² + 10² =
400 + 100 = 500
500 is not equal to the square of 25
so it is not a right angled triangle
