Answer:
32.38
Step-by-step explanation:
Sum to infinity = a1/(1 - r)
Sum to infinity = 34/(1 - (-0.05))
Sum to infinity = 34/1.05
;Therefore the sum of an infinite geometric series is...32.38
Answer:
p=(3×2)+(2.5×2)3.5
p=6+5(3.5)
p=11(3.5)
p=38.5 feet
Step-by-step explanation:
Answer:
23 boxes filled
28 trains left over
Step-by-step explanation:
718 toy trains per day
each box holds 30 toys
718 / 30 = 23.93333
23 boxes will be filled
23 x 30 = 690 toys
^ boxes x toys per box = toys in boxes
718 - 690 = 28 left over toys
Answer:
x = 30°
y = 115°
Step-by-step explanation:
Given = AB ║ DC
∠A = 2x + 10
∠B = 65
∠C = y
∠D = 3x + 20
( AD is the transversal on the parallel lines AB and DC)
∴ ∠A + ∠D = 180 and ∠B + ∠C = 180
(1) ∠A + ∠D = 180
2x + 10 + 3x + 20 = 180
5x + 30 = 180
5x = 180 - 30 = 150
x = 150÷5
x = 30°
(2) ∠B + ∠C = 180
65 + y = 180
y = 180 - 65 = 115
y = 115°
