7 tiles with plants and 2 tiles with animals...total of 9 tiles
she flips a plant tile, and does not replace it.
probability that 2nd tile is a plant = 6/8 = 0.75 = 75%
1)
We know that each coordinate (x,y) must therefore multiply to equal 7. The only numbers that multiply to 7 are 7 and 1, so B) is the correct answer.
2)
For this one, just plug in the coordinates they give you for x and y and see if either one works:
So the first one is a solution. Now plug in the second one:
Therefore, the first is a solution and the second isn't making C) the correct answer.
3)
For this one, just plug in the ordered pairs they give you and see which ones end up working:
A) and B) are the only ones that work out, so those are the correct answers.
B=8 4/7 because 6 1/7 plus 2 3/7 is 8 4/7
Please elaborate on your question so I can help you..
Answer:
x = = 10.8
Step-by-step explanation:
Both problems are done the same way. I will do the first one and you do the second one. OK?
Move the radius x to make a right triangle. The 6 unit segment bisects the chord. So, the legs of the right triangle are 6 and 9
The use the Pythagorean theorem to find x, which is the hypotenuse of the right triangle. Now,
= 10.8
None of the answer choices are to the nearest tenth. So, I am confused about that.
In the second problem, the answer should be 11.2
