The answer is there are no solutions because i just had that question and put it AND IT WAS RIGHT..
The least common multiple of 6 and 21 is 42.
A.
Number of marbles with 'B' written on them is [ n(A)] = 6.
Total number of marbles [ n(S)] = 15.
Thus, Probability is
P(A) = n(A) / n(S)
= 6/15 = 2/5. ⬅️
B.
Number of green marbles [ n(A)] = 5.
Total number of marbles [ n(S)] = 15.
Thus, Probability is
P(A) = n(A) / n(S)
= 5/15 = 1/3 ⬅️
Answer:
75.44 Square Inches
Step-by-step explanation:
The diagram of the problem is produced and attached.
To determine the area of the cleaned sector:
Let the radius of the larger sector be R
Let the radius of the smaller sector be r
Area of the larger sector
Area of the smaller sector
Area of shaded part =Area of the larger sector-Area of the smaller sector
From the diagram, R=10 Inch, r=10-7=3 Inch,
Therefore, Area of the sector cleaned
Step-by-step explanation:
Let the speed of the plane in still air = x
and speed of wind = y
Now from city A to B
dIstance = speed × time
732732 = (x - y) × 2 (1)
From city B to A
Distance = speed × time
732732 = (x + y) × 1.5 (2)
From (1) and (2)
2x - 2y = 1.5x + 1.5y
0.5x = 3.5y
x = 7y
If we plug in (1)
732732 = (7y - y) × 2
732732/12 = 12y/12
y = 61061
Since x = 7y
= 427427 miles/hr
Speed of still air plane is 427427 miles/hr
Speed of wind = 61061miles/hr
