1/3 + 1/7 = ?
7/21 + 3/21 = 10/21
The answer is 10/21.
Answer:
C = 56.5 cm
Step-by-step explanation:
<h3>
The circumference formula is C = πd. If the diameter, d, is 18 cm, then the circumference of this circle is </h3><h3>
</h3><h3>
C = π(18 cm) ≈ 18π cm ≈ 56.5 cm</h3>
The distance between the points (23,-33) and (4,9) rounded to two decimal places is 46.10.
<h3>What is the distance between the points (23,-33) and (4,9)?</h3>
The distance between two points on a graph can be determined using the equation;
D = √[ ( x₂ - x₁ )² + ( y₂ - y₁ )² ]
Given that;
- x₁ = 23
- x₂ = 4
- y₁ = -33
- y₂ = 9
We substitute our values into the equation above.
D = √[ ( x₂ - x₁ )² + ( y₂ - y₁ )² ]
D = √[ ( 4 - 23 )² + ( 9 - (-33) )² ]
D = √[ ( -19 )² + ( 42 )² ]
D = √[ 361 + 1764 ]
D = √[ 2125 ]
D = 46.10
Therefore, the distance between the points (23,-33) and (4,9) rounded to two decimal places is 46.10.
