The answer is D.
Find the scale of each dimension:
B: 6/3 = 2 and 10/5 = 2, both dimensions have the same scale factor of 2.
C: 15/3 = 5 and 25/5 = 5, both dimensions have the same scale factor of 5.
D: 60/3 = 20 and 90/5 = 18, each dimension has a different scale factor so is not an enlargement.
Basically we just use this inequality:
70 + 0.02x = 45 + 0.04x
25 + 0.02x = 0.04x
25 = 0.02x
x = 1250
It will be the better choice if you make 1250 copies or less
A. 53/100
B. 163/200
C. 53/10
D. 163/20
Those are the answers to the question.
Answer:

Answer:
width of the river is 60.16 m
Step-by-step explanation:
Refer the attached figure
AB = width of river
We are required to find the width of river .
Since we are given that . Trigonomos spotted a tree across the river and marked the spot directly across from it.
Then he walked to the another point 15 meters down the river .i.e. BC = 15 m
He also found the angle between his side of the river and the line connecting him to the tree i.e. ∠ACB = 76°
So, now to calculate the width of river i.e. AB , we will use trigonometric ratio
Thus the width of the river is 60.16 m
