Answer:
The range is 19
Step-by-step explanation:
First, you have to order the numbers from least to greatest:
-9.5, -3.1, 3.1, 3.2, 4.7, 4.9, 5.4, 6.3, 9.5
Then, you have to find the difference between the largest number and and smallest number. You do this by subtracting them:
9.5 - (-9.5)= 19
So, the range is 19
"c" is the hypotenuse of the largest triangle, and "a" is that triangle's shortest side. Thus the ratio is
... (longest side)/(shortest side)
Since all the triangles in the figure are similar, to complete the proportion, you need to recognize the triangle that "a" is the longest side of, then find the shortest side of that triangle.
"a" is the longest side (hypotenuse) of the smallest triangle. The shortest side of that triangle is "r". So, your proportion is ...
... c/a = a/r
The appropriate choice is the 2nd one, ...
... r

Answer:
x = 3
Step-by-step explanation:
- Subtract 15 from each side, so it now looks like this: 21 = 7x
- Divide each side by 7 to cancel out the 7 next to x. It should now look like this: 3 = x
