Given:
Total number of marbles = 15
Probability of randomly selecting a green marble = .
Probability of randomly selecting a green marble, replacing it, and then randomly selecting a blue marble = .
To find:
The number of blue marbles.
Solution:
Let the number of blue marbles be x.
It is given that,
Probability of randomly selecting a green marble, replacing it, and then randomly selecting a blue marble is . So,
Multiply both sides by 75.
Therefore, the number of blue marbles in the bag is 6.
Answer:
Width is 10ft and length is 6ft.
Step-by-step explanation:
The area of a shape is the amount inside a shape. It is found using multiplication or A = l*w. Since the width is w and the length is 4ft less than its width or w - 4, use these expressions in the area formula to find their amount.
Subtract 60 from both sides and factor the quadratic to solve for w.
Set each factor equal to 0 and solve.
w - 10 = 0 so w = 10
w + 6 = 0 so w = -6.
Since w represents a length or distance it cannot be negative, this means the width is 10. The length which is w - 4ft is 10 -4 = 6. The length is 6 ft.
