First you find common denominator which is 18, you don't have to change 2/18
1x3=3
6x3=18
so 3/18 plus 2/18= 5/18
So your answer is 5/18
Answer:
18 feet
Step-by-step explanation:
Use Pyth Theorem
10^2 + 15^2 = c^2
100 + 225 = c^2
325 = c^2
18.027 = c
Let's use the variable x to represent the number.
3x+12-5x=22
Combine like terms
-2x+12=22
Subtract 12 from both sides
-2x=10
Divide both sides by -2
x=-5
Final answer: The number is -5
6:15 is in ratio form..... If you mean fraction form, a ratio is equivalent to a fraction, so the answer is 6/15
The equation of the circle whose center is at the origin and whose diameter is 12.5 is x²+y²=39.0625
<h3>Equation of a circle</h3>
The formula for finding the equation of a circle is expressed as:
(x-a)² + (y - b)² = r²
where
(a, b) is the centre
r is the radius
Given the following
(a, b) = (0, 0)
r = 12.5/2 = 6.25
Substitute
(x-0)² + (y - 0)² = 6.25²
x²+y²=39.0625
Hence the equation of the circle whose center is at the origin and whose diameter is 12.5 is x²+y²=39.0625
