There are four highlights in the paragraph that show equations or phrases
aivan3 [116]

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.

The radius of a circle is 16 millimeters. What is the circle's area?
Kisachek [45]

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>

  • <u></u>3.14 *16^2
  • 3.14*256
  • 803.84

Therefore, the area is 803.84 square millimeters.

Have a lovely rest of your day/night, and good luck with your assignments! ♡

A number is doubled, then decreased by 13.7. The result is greater than 125.28. What is the smallest integer that satisfies this
Elina [12.6K]

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.

Rudik [331]

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.
