Answer:
b ≈ 9.5, c ≈ 14.7
Step-by-step explanation:
Using the Sine rule in Δ ABC, that is
=
, substitute values
=
( cross- multiply )
b × sin23° = 7 × sin32° ( divide both sides by sin23° )
b = ≈ 9.5 ( to the nearest tenth )
Also
=
=
( cross- multiply )
c × sin23° = 7 × sin125° ( divide both sides by sin23° )
c = ≈ 14.7 ( to the nearest tenth )
25 cubic inches because you know that every cone is a third of the volume of the cylinder with which it shares a height and base with.
Answer: ,

Step-by-step explanation:
Here, x represents the number of hours Zoe spent running on her wheel and y represents the number of hours spent scratching her cage.
Julie was awoke for at least an hour running on her exercise wheel and scratching the of her cage.
⇒
She ran on her wheel at least twice as long as she scratched at the corners of her cage.
⇒
Also, She spent more than 1/4 hour running on her wheel.
⇒
And, we know that number of hours can not be negative.
⇒
