Round 253.5198 to the nearest thousandth
kipiarov [429]

Answer:

253.520

Step-by-step explanation:

Let us see what is the thousandths place...

It is the third digit to the right.

253.5198 rounded is about

253.520.

I can tell because you take the thousandths place, look at the one to the right of it, then if it is greater than 5, you make the thousandths place greater. Since it's a 9, you move the extra 10 thousandths to the next thing- the hundredths. and you get 253.520.

What is the largest three-digit number that is a multiple of both $24$ and $30$
irina [24]

We are given two numbers $24 and $30.

We need to find the largest three-digit number that is a multiple of both $24 and $30.

So, we need to find the largest common multiple of 24 and 30.

<em>In order to find the largest common multiple, we need to multiply both numbers.</em>

If we multiply 24 and 30, we would get

24 × 30 = 720.

Therefore, the largest three-digit number that is a multiple of both $24 and $30 is 720.

A square is inscribed in a circle. If the area of the square is 9 in2, what is the ratio of the circumference of the circle to t
IgorC [24]

The ratio of the circumference of the circle to the perimeter of the square is \pi \sqrt{2}:4

<em><u>Explanation</u></em>

Area of the square = 9 inch²

If the side length of the square is a, then

a^2 = 9 \\ \\ a= \sqrt{9} =3

So the side length of the square is 3 inch.

Now as the square is inscribed in a circle, so the diagonal of the square will be diameter of the circle.

Length of the diagonal of square = a\sqrt{2} = 3\sqrt{2} inch

So, the diameter of the circle = 3\sqrt{2} inch

If the radius of the circle is r, then

2r = 3\sqrt{2} \\ \\ r= \frac{3\sqrt{2}}{2}

Circumference of the circle, 2\pi r= 2\pi *\frac{3\sqrt{2}}{2}= 3\pi \sqrt{2} inch

and Perimeter of the square, 4a = (4*3)inch= 12 inch

So, the ratio will be: 3\pi \sqrt{2} : 12 = \pi \sqrt{2} : 4
