20 total marbles....7 are green
probability on first draw is 7/20...and since the marble was not replaced, the probability on the second draw is 6/19. And since they cant happen at the same time, we multiply
7/20 * 6/19 = 42/380 which reduces to 21/190
You'd want to buy the 4 by 5 and the 11 by 14 because if you times 4 by 3 and 5 by 3, the answer would be 12 by 15 which is the closet or the most similar pair
Answer:
$.125
Step-by-step explanation:
60 minutes = 1 hour
60 minutes for $7.50
So, $7.50/60 = $0.125
Answer: 12.00 units
<span>An area should be measured in square units so the area in the question should be 132 square units. In a rectangle having an area of 132 square units and a length of 11 units, the width (W) is computed as follows:</span>
W=A/L
W=132/11
<span>12.00 units</span>
Answer:
Prove that KL is equal to c by Pythagorean Theorem.
Step-by-step explanation:
In the two triangles triangle KLM is a right triangle with sides a and b as the two legs of the right triangle .We can apply Pythagorean Theorem to find KL.
In triangle KGF two sides are a and b .If we prove KL=EF then Pythagorean Theorem will be true for triangle KGF and hence we can prove triangle KGF to be a right triangle.
The correct option to prove triangle KGF to be a right triangle is to Prove that KL is equal to c by Pythagorean Theorem.
