Answer: Choice B
12.5 < x < 18.9
================================================
Explanation:
We have a triangle with these side lengths:
- a = 10
- b = 16
- c = x = unknown
Let's assume that b = 16 is the largest side of this triangle.
By the converse of the pythagorean theorem, we need 
to be true in order for an acute triangle to happen.
So,
Now let's consider the possibility that the missing side x is actually the longest side.
Using the same theorem as before, we would say,
We found that x > 12.5 and x < 18.9
This is the same as saying 12.5 < x and x < 18.9
Put together, they form the approximate answer of 12.5 < x < 18.9
2.20 rounded to the nearest tenth is 2.2 it is already rounded if it was 2.29 it would be 2.3
f(3) is where the line is on the Y axis when X is 3:
Looking at the red line when it passes over X3, the line is on Y8.
The answer is B.8
While rotations, translations and reflexions do not alter the volume of the matter, dilation does increases the volume.
So the answer would be, dilation increases the volume while other types of transformations do not.
Por un sistema de ecuaciones, tiene-se que:
- Cada lapiz cuesta 20 ptas.
- Cada boligrafo cuesta 50 ptas.
-------------------------
- Considera-se un sistema de ecuaciones, con cada boligrafo custando x y cada lapiz custando y.
- <u>Boligrafo cuesta 30 mas que un lapiz</u>, o sea,
- <u>8 boligrafos y 15 lapices cuesta 700</u>, o sea,
-------------------------
- Aplicando el <u>primer ecuación en la segunda, </u>tiene-se el cuesto de cada lapiz:
Cada lapiz cuesta 20 ptas.
-------------------------
Por fin, el cuesto de cada boligrafo es dado por:
Cada boligrafo cuesta 50 ptas.
