Answer:
67.9705...
Add the two numbers.
67 16/34 + 14/28 = 67.9605...
That is your answer.
Answer:
AC = √105 ≈ 10 cm (nearest whole number)
Step-by-step explanation:
Use Pythagoras' Theorem: a² + b² = c²
(where a and b are the legs, and c is the hypotenuse of a right triangle)
Give one of the legs = 4cm and the hypotenuse = 11 cm:
⇒ 4² + AC² = 11²
⇒ 16 + AC² = 121
⇒ AC² = 121 - 16
⇒ AC² = 105
⇒ AC = ±√105
As distance is positive, length of AC = √105 ≈ 10 cm (nearest whole number)
Answer:
Geometric Sequence
Step-by-step explanation:
As you can see, the terms are of consecutive sequences.
The 3rd term ÷ The 2nd term = 3
The 4th term ÷ The 3rd term = 3
The ratio between the consecutive terms is the same. Therefore, it's a geometric sequence.
