A reflection across the line y=0 (AKA the x-axis)
and then across the line x=0 (AKA the y-axis)
is the same as a rotation of 180º
clockwise about the origin because the lines intersect at the origin and at a 90º angle.
While all of that is true, you could also be more general, because reflecting over any two lines that intersect at the origin will result in a rotation about the origin and have an angle of rotation equal to twice that of the acute angle formed between the intersecting lines.
Answer:
803.84 millimeters²
Step-by-step explanation:
How do we find the area of a circle?
- The area of a circle is πr², where r = radius. In this case, we have to approximate pi to 3.14.
<u>Solving</u>
Therefore, the area is 803.84 square millimeters.

150 because
45/x=30/100 =
30x=4500
divide both by 30
and x=150
Answer:
x > 69.49
Step-by-step explanation:
Step 1: Write out equation
2x - 13.7 > 125.28
Step 2: Add 13.7 to both sides
2x > 138.98
Step 3: Isolate <em>x </em>by dividing both sides by 2
x > 69.49
So <em>x</em> has to be greater than 70 in order to fit into the question context.
Answer:
C. 1/10
Step-by-step explanation:
yes, it is in the thousands place, but it's comparing the 7 in the ten thousands place to the 7 in the thousandths place. If it said the 7 in the ten thousands is _____ the value of the 7 in the thousands place, the answer would be A. 10x.
10,000/10=1,000 so the answer is C. 1/10.
