*This is on the assumption that we are finding x*


For this, you will be doing a proportion, and your equation will look like this: \frac{40}{x} =\frac{50}{30}


Firstly, you will need to cross-multiply. Your equation will look like this: 1200=50x


And all you need to do with this equation is divide 50 on each side, and your answer should be 24=x

Mathius walked ⅜ mile to school. Eva walked ⅖ mile to school. How many more
zalisa [80]

Answer:

132ft

Step-by-step explanation:

Mathius Distance = 3/8 mile

Eva Distance        = 2/5 mile

1 mile = 5,280ft

1. Start by multiplying the mile distance of Mathius to the distance of 1 mile in feet.

5,280ft x 3/8 = 15840ft/8 = 1980ft

2. Do the same thing as number 1 but for Eva's distance now.

5,280ft x 2/5 = 10560ft/5 = 2112ft

3. Subtract Eva's Distance from Mathius' Distance for the answer.

2112ft (Eva) - 1980ft (Mathius) = <em>132ft</em>

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
