I NEED HELP ON NUMBER 12 AND ALSO NEED EXPLANTION
topjm [15]

picture is blurry but if they are similar find the scale between the known sides

 smaller triangle bottom looks like it says 8?

 the larger one is 16

8/16 = 0.5 so the smaller one is half the size of the larger one

 so half of 8 is 4 so y = 4

 since they are similar the angles would stay the same so angle B would be the same as s which is shown as 27 degrees.

Justin is on a road trip. Over the past two days, he’s driven a total distance of 504 miles at an average speed of 56 miles/hour
irakobra [83]
Recall d  = rt, distance = rate * time.

now, he has a speed rate of 56 mph for a distance of 504

\bf d=rt\implies 504=56t\implies \cfrac{504}{56}=t\implies \stackrel{hours}{9}=t

so, at that speed the whole driving time is 9 hours then.  Ok, he drove 2 hours today, that means he drove 7 yesterday, 9 - 2.

how many miles is it for 7 hours at 56mph?  d = rt ---> d = 56 * 7

that many miles he drove yesterday.
