Answer:
13
Step-by-step explanation:
It would have to be 13, because if you look at the top of the shape, you see the little 45 degrees. You can also see the 90 degrees right angle. Triangles no matter what add up to 180 degrees.
(a is the unknown angle in the bottom right)
90+45+a=180
45+a=90
a=45
now that we have that , we know that it has to be symmetrical.
so it can only be 13
hope this helps!
Answer:
−x^3+5x^2-2x−12
Step-by-step explanation:
For this case, what you should see is where the graph cuts the x-axis.
Notice that the graph cuts to the x axis in three different points.
Then the value of x that is in the domain of the function in this case is:
x = 1
For this value of x the function is zero.
Answer:
x = 1
40 tiles
Assuming the vowels and non-vowels are equal to the five picked, there would be 40 tiles that are vowels.
You have picked five different letters. 5% or 1/20 of 100. If two of those five were vowels, then if you consistently pick 2/5 vowels every time, a predicted 40 tiles will be vowels, 60 would not.
First, you can divide 100 by 25. Next, you will figure out that the answer is 4 . Last, you will add 4 +4 =8.
