1. Selena has to walk <em>to</em> school and <em>from </em>school.
That means that each day, she walks the distance from her house to the school twice.
If she walks 2/3 in a day, the distance must be half of that, or 1/3.
2. 3 batches = 3/4 cup.
Divide each side by 3.
1 batch = 1/4 cup.
3. 5 eighths minus 1 eighth = 4 eighths.
Since we have the same bottom number, we don't need to do anything special. This problem is just the same as something like <em>5 apples - 1 apple.</em>
4. First, let's convert 6 into thirds.
6 × 3 = 18
Therefore, 6 = 18/3.
Add 6 and 2/3.
18/3 + 2/3
20/3
5. To be a composite number, a number needs to be divisible by something besides 1 or itself.
Check your divisibility rules...
39 is divisible by 3 (39 ÷ 3 = 13), so this could be his house number.
6. 12 cupcakes - 9 chocolate = 3 vanilla.
3 vanilla cupcakes out of 12. (3/12)
We can simplify this fraction. 3 and 12 are both divisible by 3.
3/12 = 3÷3 / 12÷3 = 1/4
A circle is a curve sketched out by a point moving in a plane. If the distance from A to C is 6 units, then the distance from C to B is 6 units.
<h3>What is a circle?</h3>
A circle is a curve sketched out by a point moving in a plane so that its distance from a given point is constant; alternatively, it is the shape formed by all points in a plane that are at a set distance from a given point, the centre.
If the distance from A to C is 6 units, then the distance from C to B is 6 units. This is because AC and BC are the radii of the circle, therefore, both are equal to each other.

Answer:
6.2 cm
Step-by-step explanation:
Apply the Law of cosines, given as:
c² = a² + b² - 2ab×Cos(C)
Where,
a = 4 cm
b = 8 cm
c = AB = ??
C = 50°
Plug in the value into the equation
c² = 4² + 8² - 2*4*8*Cos(50)
c² = 16 + 64 - 64*Cos(50)
c² = 80 - 64*Cos(50)
c² = 38.861593
c = √38.861593
c = 6.2 cm (nearest tenth)
The first few twin prime pairs are : (3, 5), (5, 7), (11, 13), (17, 19), (29, 31), (41, 43), (59, 61), (71, 73), (101, 103), (107, 109), (137, 139), …etc. FACT : There are 409 Twin
The correct answer is B.
Feet below sea level means that the higher number, the lower the elevation. B has the highest number.
