Answer:
80 cookies per hour
Step-by-step explanation:
First, let's make 3 1/2 a decimal, so that would be 3.5. Now lets make this problem a proportion. 280/3.5 means that Stan makes 280 cookies every 3.5 hours.
Let's simply this proportion to find the unit rate. 3.5 divided by 3.5 is 1, so dividing by 3.5 will help find the unit rate. We already did the bottom, so let's do the top. 280 divided by 3.5 is 80.
Therefore the unit rate is 80.

I used a unit calculator- they are extremely helpful
Q=p(r+s)
Divide by (r+s)
q/r+s=p
Answer:
one
Step-by-step explanation:
Where the two functions intersect
Let A be the position of the ship at which the rock is found at B, after travelling 15.7 miles the ship reaches point C, thus ABC forms a triangle that has the dimensions of
AC=15.7
and
∠x=BAC=90-44°20'=45°40'
∠y=∠BCA=360-270=90
∠ABC=180-∠x-∠y=44°20'
therefore using sine law
BC/sin (44°40')=15.7/sin (45°20')
⇒BC=15.5184 miles
