Answer:
SA = 31.714 km²
Step-by-step explanation:
SA = πr² + πrl
SA = 3.14(1)² + 3.14(1)(9.1)
SA = 3.14 + 28.574
SA = 31.714 km²
Angle BCA = 180 - 100
angle BCA = 80
Isosceles triangle ABC has two congruent angles, A and B
2x + 80 = 180
2x = 100
Angles A and B = 50 or y and z = 50
I think lines AB and DE are supposed to be parallel, so angles y and x are consecutive interior angles (supplementary)
x = 180 - 50 = 130
Answer:
2 × 10⁵
Step-by-step explanation:
The following data were obtained from the question:
6×10⁹/ 3×10⁴ =?
The above expression can be simplified as follow:
6×10⁹/ 3×10⁴ = 6×10⁹ ÷ 3×10⁴
Recall:
Aᵐ ÷ Aⁿ = Aᵐ ¯ ⁿ
Therefore,
6×10⁹ ÷ 3×10⁴ = (6/3) × 10⁹ ¯ ⁴
6×10⁹ ÷ 3×10⁴ = 2 × 10⁵
Thus, 6×10⁹/ 3×10⁴ is equal to 2 × 10⁵
