1. Hexagonal pyramid, because the base is a hexagon and the lateral faces all meet up at the same vertex point.

2. Triangular prism. The parallel faces (base faces) are triangles and the lateral faces are rectangles.

3. Tetrahedron. This is a four sided object made of triangles for each face. You can also call this a triangular pyramid as the base is a triangle with the lateral sides meeting at the same vertex.

Rolando is 17. In four years, his age will be 3/2 the age of his sister Marisa. How old will Marisa be in three years
Bess [88]
To find the answer, we can first find the age of Rolando in four year:

17+4
=21

We can then proceed to find the current age of Marisa,which is 3/2 of Rolando’s age calculated above:

Let Marisa’s age be y.

3/2 y =21
y = 21 × 2/3
y = 42/3
y = 14

Therefore Marisa is currently 14 years old.

In three years, Marisa would be:

14+3
=17

Therefore, she will be 17 years old.

Hope it helps!

A midsegment is given by the formula:
\frac{x1+x2}{2} , \frac{y1+y2}{2}

Where x1, x2, y1, and y2 correspond to their respective coordinates. We can do the equation:

\frac{-3+5}{2} , \frac{-1+3}{2}
This gets us a midpoint coordinate of <span>(1,1)

</span>As for distance, it will be found by doing:
\sqrt{(x2-x1)^2+(y2-y1)^2}
We can do the following:

\sqrt{(5-(-3))^2+(3-(-1))^2}
\sqrt{(8)^2+(4)^2}
\sqrt{64+16}
This simplifies to 4 \sqrt{5}
