Answer:
The ratio of the areas of the smaller rectangle to the larger rectangle is 
Step-by-step explanation:
we know that
if two figures are similar, then the ratio of its areas is equal to the scale factor squared
Let
z-----> the scale factor
x-----> the area of the smaller rectangle
y----> the area of the larger rectangle
so

substitute the values

simplify

That means, the area of the larger rectangle is 9 times the area of the smaller rectangle
------> the scale factor
That means, the dimensions of the larger rectangle is 3 times the dimensions of the smaller rectangle
Cos x = 15÷17
because cos is adjacent side over hypotenuse.
Answer:
Speed= 67.5 miles per hour
Step-by-step explanation:
Google maps has told Juanita that her car trip will be 32 miles.
Juanita has already gone 14 miles.
Remaining miles left to travel
= 32-14
Remaining miles left to travel
= 18 miles
She has only 16 minutes to reach her destination.
The required speed for her to reach her destination
= Distance/time
Her time = 16 minutes
Her time = 16/60
Her time =4/15 hours
Speed= distance/time
Speed= 18 /(4/15)
Speed=18* 15/4
Speed= 67.5 miles per hour
100,000 (sorry if I'm wrong)
