Answer:
Scale factor of 2
Explanation:
I compared the lengths of AC to DF. AC is one unit long, whereas DF is two units long, so DF is dilated by a scale factor of 2.
Answer:
option B
2
Step-by-step explanation:
Given in the question
DO,h(7, 9) → (14, 18)
Formula to use
<h3>√(x1-x2)²+(y1-y2)²</h3>
distance formula = √((7-0)²+(9-0)²) = √(7²+9²) = √130
distance formula = √((14-0)²+(18-0)²) = √(14²+18²) = 2√130
Scale factor
√130 = 2√130
d = 2d
Short answer: 60°
Explanation: All inner angle of a triangle add up to 180° so 180° - 60° - 60° = 60°
Subtracting the 2 already given angels must be subtracted from 180° to know the final angle
3/4 of 100 is 75 so 3 quarters of a mile is 0.75
