Answer:
Step-by-step explanation:
sin(θ) = 2/7
sin²(θ) +cos²(θ) =1


Answer is positive because tangent is positive, sin is also positive, and tan=sin/cos.
50 + 0.50m = 0.70m
50 = 0.70m - 0.50m
50 = 0.20m
50 / 0.20 = m
250 = m......the plans will cost the same at 250 miles <==
50 + 0.50(250) = 50 + 125 = 175
0.70(250) = 175
and they would both cost $ 175 <==
Answer:
-6 ,
Step-by-step explanation:
24 divided by 4 = 6
Solution
For this case we can create the following schema
We can use the definition of distance:
x= vt
We can find the relative velocity:

And the distance between both is required to be 2 mi so then we can find the time like this:

Then the answer is:
1 hr
Answer:
B
Step-by-step explanation:
Volume = Volume of cylinder + Volume of semi sphere
= pi*r^2*h+(2/3)*pi*r^3
=pi*(4*12+16/3)=pi*53.3
