Answer:
B. A dilation with a scale factor of 0.5
Step-by-step explanation:
A. is wrong because it is congruent transformation because reflections keep the angles and side lengths of the figure the same.
B. is right because it is NOT congruent because a dilation of any scale factor other than 1 results in a similar figure, because the side lengths are proprtional but not equivalent
C. is wrong because translations keep the angles and side lengths of the figure the same.
D. is wrong because a scale factor of 1 changes nothing about the figure.
75x+2=
75x-2=-2. move the 2 to the other side
75x=-2 now divide 75 both sides
75/75x=-2/75
x=-2/75
X is the undefined variable hope it helps
Answer:
592 hours
Step-by-step explanation:
Given


Required
Determine the time taken to cover the area
Since, the oil formed a circular pattern; the question will be answered using area of a circle

Let t represent the time take to cover 11000m²;
The relationship between these parameters is:

Substitute 3.14 for π

Divide both sides by 3.14



Take square root of both sides



Divide both sides by 0.10




<em>(</em><em>Approximated)</em>
<em>Hence, it'll take approximately 592 hours to cover the given area</em>
