Answer:
B) 24 sq. in.
Step-by-step explanation:
A = (1/2)bh
= (1/2)(8 inches)(6 inches)
= (1/2)(48 sq. in.)
A = 24 sq. in. is the area of the given triangle.
The answer is A and B
its hard to use the radical sign typing here
but if you need it i can update my answer
There are 14 nickels and 7 dimes.
(You can check by multiplying 14 by 5 for nickels and 7 times 10 for dimes. This would add up to 1.35)
X^2-11x+24
(x-3) (x-8)
----> check
x^2+(-3x-8x)+(-3 x -8=24)
x^2-11x+24
A bag contains 3 red marbles and 4 blue marbles. a marble is taken at random and replaced. Another marble is taken from the bag. Work out the probability that the two marbles taken from the bag are the same color.
<span>Total number of marbles in the bag is 3 + 4 = 7.<span>The problem asks for the probability of (RR) or (BB).</span>It's worthy to note we are replacing the balls after each draw, which means we always have 7 to draw from</span>Since each draw is independent, we take the product of each event for the total event probability.
P(RR) = 3/7 * 3/7 = 9/49
P(BB) = 4/7 * 4/7 = 16/49
We want to know P(RR) + P(BB)
<span>P(RR) + P(BB) = 9/49 + 16/49 = 25/49</span>
