1 answer:
Answer:
3, 5, 8, 13
Step-by-step explanation:
aₙ = aₙ₋₁ + aₙ₋₂
a₃ = a₂ + a₁ = 2 + 1 = 3
a₄ = a₃ + a₂ = 3 + 2 = 5
a₅ = a₄ + a₃ = 5 + 3 = 8
a₆ = a₅ + a₄ = 8 + 5 = 13

Answer:
40 baskets
Step-by-step explanation:
Find out how many baskets she can make in an hour. Since she makes 4 in 1/2 an hour, multiply 4 by 2 to find out how much she makes in an hour. She makes 8 baskets an hour, so multiply 8 by 5. 8 x 5 = 40.
Answer:
2*2*9+4*12*3=36+144=180
Step-by-step explanation:
Step-by-step explanation:
Number 1
180° = x + 70° + 55° + 30°
180° = x + 155°
x = 180° - 155°
x = 25°
Number 2
x° = 93°
y° = 47°
z° = 180° - 47° - 93°
z° = 180° - 140°
z° = 40°
