Step-by-step explanation:
Question 9:
Hypotenuse = 7
Leg = Hypotenuse / √2 = 7/√2 = 7√2 / 2.
Therefore x = y = 7√2 / 2.
Question 10:
Leg = 10
Since x is also a Leg, x = 10.
Hypotenuse = Leg * √2 = 10√2. => y = 10√2.
Question 11:
Leg = 7
Since x is also a Leg, x = 7.
Hypotenuse = Leg * √2 = 7√2, => y = 7√2.
V= pi r^2h
180= pi (5)^2h
180=78.5h
Divide by 78.5
h= 2.29
h= 2.3
Sorry could not type pi symbol
We can setup an inequality to model this situation.
42h + 546 > 5000
