Correct Question
Mara thinks x ≤ 6 will earn the highest score here.
David thinks x < 6 will.
Who is correct?
Answer:
Mara is correct
Step-by-step explanation:
In the above question, we are given two inequality equations
1) Mara: x ≤ 6
2) David : x < 6
For David , x < 6 means the score which is represented by x is less than 6
For Mara, x ≤ 6 means the score which is represented by x is less than or equal to 6
Therefore, Mara is correct because x ≤ 6 will earn the highest score here.
First one hope this helps!
Volume of cylinder = Pi x r^2 x h
Volume = 225pi
r = 3
Substitute values into equations
225pi = Pi x (3)^2 x h
225pi = 9pi x h
Hence h = 225pi/9pi = 25
So h is 25 cm.
Answer:
True
Step-by-step explanation:
If the triangle was a right angled triangle then we can prove it using the Pythagoras theorem: c² = a² + b²
c is the largest side and a and b are the two smaller sides of the triangle.
So if this is true then √72² + 154² should be 170:
170² = 72² + 154²
28900 = 5184 + 23716
28900 = 28900
So we have proved using Pythagoras theorem that the triangle is a right angled triangle.
