*****What is 1/3 + 1/4
1 answer:
Answer: 7/12
Step-by-step explanation: To add these two fractions together, we start by finding their common denominator.
The common denominator for 3 and 4 will be the least common multiple of 3 and 4 which is 12. So we multiply the top and bottom of our first fraction by 4 and the top and bottom of our second fraction by 3. That gives us 4/12 + 3/12 which simplifies to 7/12.
Therefore, 1/3 + 1/4 = 7/12 which is in lowest terms.

Answer:
x ≈ 4.2 (nearest tenth)
Step-by-step explanation:
The chord of length 4 is the base of an isosceles triangle with height of 3.7 and sides equal to the radius (x).
An isosceles triangle comprises two right triangles, each with:
- base = 2 units
- height = 3.7 units
- hypotenuse = x units
Therefore, to find x use Pythagoras' Theorem: a² + b² = c²
(where a and b are the legs, and c is the hypotenuse, of a right triangle)
⇒ a² + b² = c²
⇒ 2² + 3.7² = x²
⇒ x² = 17.69
⇒ x = √(17.69)
⇒ x = 4.2 (nearest tenth)
