Answer:
0.2
Step-by-step explanation:
2/10=0.2
The answer to your question is 21.5
Step-by-step explanation:
Part A: We can write 40 + x + 25 = 180 because these angles are supplementary, meaning they add up to 180 degrees, and when we solve for x, we get x = 115°.
Part B: We can write y = x + 25 because these two angles are vertical angles, meaning they are equal and formed from the same lines. We know that x = 115°, so when we plug that in we get y = 140°.
Part C: z = 40° because these two angles are vertical angles. I hope this helps!
Using translation concepts, the equation for the transformed function h(x) is given by:
h(x) = f(-x - 1).
<h3>What is a translation?</h3>
A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s definition or in it’s domain. Examples are shift left/right or bottom/up, vertical or horizontal stretching or compression, and reflections over the x-axis or the y-axis.
For this problem, the effect of the two changes is given as follows:
- Reflection over the y-axis, hence h(x) = f(-x).
- Translation of one unit right, that is, x -> x - 1, hence h(x) = f(-x - 1).

Let the numbers be:
a, a+b, a+2b
mean of the numbers is:
(a+a+b+a+2b)/3=10
(3a+3b)/3=10
a+b=10
thus second term is 10
The sum of square will be:
((10 - b)² + 10² + (10 + b)²<span>) / 3 = 394
</span>(100 - 20b + b² + 100 + 100 + 20b + b²<span>) / 3 = 394
</span><span>(300 + 2b</span>²<span>) / 3 = 394
</span>(150+b²)=591
b²=441
b=-21,21
thus the numbers will be:
10-21, 10, 10+21
=-11,10,31
