Answer:
3 2/3
The fractions have unlike denominators. First, find the Least Common Denominator and rewrite the fractions with the common denominator.
Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD. This is basically multiplying each fraction by 1.
Complete the multiplication and the equation becomes
The two fractions now have like denominators so you can add the numerators.
Then:
This fraction can be reduced by dividing both the numerator and denominator by the Greatest Common Factor of 22 and 6 using
Convert to a mixed number using
long division for 11 ÷ 3 = 3R2, so
Therefore:
The least common denominator is
20 = 2 * 2 * 5
25 = 5 * 5
The least common denominator has two 5s and two 2s.
LCD = 2*2*5*5 = 100
17/20 = 17 * 5/ 20*5 = 85 / 100
21/25 = 21* 4/25*4 = 84 / 100
Talk about close
17/20 > 21/25 <<<< answer
But I hate to have predicted that before hand.
Answer:
The answer to your question is (x - 7)² + y² = 81
Step-by-step explanation:
Data
Center = (7, 0)
radius = 9
Process
To find the standard equation of a circle, just substitute the values of the center and the radius.
Standar equation of a circle
(x - h)² + (y - k)² = r²
-Identify the values of h and k
h = 7 k = 0 and r = 9
-Substitution
(x - 7)² + (y - 0)² = 9²
-Simplification
(x - 7)² + y² = 81
Answer: V = L (k)
Step-by-step explanation:
Hi, to answer this question we have to write an equation with the information given:
- <em>Volume of a box = V
</em>
- <em>Length = l
</em>
- <em>Constant of proportionality
= k</em>
We know that the volume of the box (V) varies directly with its length (l).
So, the expression for the volume is:
V = L (k)

Answer: I believe the answer here would be 52.5 degrees.
Step-by-step explanation: Because an isosceles triangle has two equal sides, their base angles would be the same. The angles of a triangle add up to 180 degrees, so you would subtract 75 from 180 and divide 105 by two in order to find one of the base angles.
