72% as a decimal is 0.72.

72% as a fraction is 72/100 = 18/25.

Think of 72% as 72.0% and then move the decimal point to the left two spaces (this applies to all percentages) which results in .72, and there you have your answer to the decimal. Then, you can convert the decimal to a fraction by writing .72/1 which is 72/100. Then simplify the fraction (if possible) to get 18/25.

The equation of a circle C, with centre O, is:

Nataliya [291]

Answer:

a) The center coordinates O is (0,0)

b) The radius C = 15

Step-by-step explanation:

The given equation of the circle is : $x^{2} + y^{2} = 225$

Now, general form of the equation of the circle is:

$(x-h)^{2} + (y - k)^{2} = r^{2}$

where (h,k) are the center co -ordinates and r is the radius of the circle.

Comparing the general equation with the given equation, we get

$(x-0)^{2} + (y - 0)^{2} = (15)^{2}$

So, here the center coordinates (h,k) = (0,0)

And the radius of the given circle is r = 15

Find four consecutive numbers whose sum equals 218

Softa [21]

Answer: 53, 54, 55, and 56

Step-by-step explanation: This problem states that the sum of 4 consecutive numbers is 218 and it asks us to find the numbers.

4 consecutive numbers can be represented as followed.

X ⇒ <em>first number</em>

X + 1 ⇒ <em>second number</em>

X + 2 ⇒ <em>third number</em>

X + 3 ⇒ <em>fourth number</em>

Since the sum of our 4 consecutive numbers is 218, we can set up an equation to represent this.

X + X + 1 + X + 2 + X + 3 = 218

On the left side of the equation, we can combine our x's and our numbers.

4x + 6 = 218

-6 -6 ← <em><u>subtract 6 from both sides of the equation</u></em>

4x = 212

÷4 ÷4 ← <u><em>divide both sides of the equation by 4</em></u>

<u>X = 53</u>

<u />

X ⇒ <em>first number = 53</em>

X + 1 ⇒ <em>second number = 54</em>

X + 2 ⇒ <em>third number = 55</em>

X + 3 ⇒ <em>fourth number = 56</em>

<em />

<em>Therefore, our 4 consecutive numbers are </em><em>53</em><em>, </em><em>54</em><em>, </em><em>55</em><em>, and </em><em>56</em><em>.</em>
