<h2>Answer:</h2>

Ellipse---- Diagonal cross section of a cylinder.

Circle---- Cross section parallel to the base of a cone.

Sphere---- Shape created when a semi-circle is rotated around the y-axis.

Great circle---- Diagonal cross section through the widest part of a sphere.

Triangle---- Perpendicular cross section of a cone

<h2>Step-by-step explanation:</h2>

Ellipse--

It is the plane curve which is obtained when we take a diagonal cross section of the cylinder.

Circle--

We know that when the cross-section of a solid is taken parallel to it's base then the figure so obtained is similar to the base of the solid.

Now we know that the base of a solid is in the shape of a circle.

Hence, when the slicing is done parallel to the base of a cone then we obtain a circle.

Sphere--

A sphere is obtained when we rotate a semi-circle about any line or any axis.

Great Circle--

A great circle is obtained when a plane cuts the sphere diagonally i.e. through it's center.

Triangle--

We know that when a cross section is taken perpendicular to the base of a cone then the cross-section so obtained is a figure similar to the face of a solid.

Hence, the cross-section will be a triangle.

Meagan walked 4/10 mile to the park.she walked the same distance home.how much did she walk altogether? Write in simplest form

avanturin [10]

We add them up to find the total distance :

$\dfrac{4}{10} + \dfrac{4}{10} = \dfrac{8}{10} = \dfrac{4 \times 2}{5 \times 2} = \dfrac{4}{5}$

$\text {She walked } \dfrac{4}{5} \text { miles}$

Answer: B

Step-by-step explanation:

Let's work this problem backwards. So, if he has y dollars left after spending 25% the second time or 3/4 of the money left. So, inverse it to get $\frac{4}{3}$ y. Then, do the same for 20% or 4/5, then 4/3y * 5/4 = 5/3y

The average of 8,6,9,12 and 4x is x. What is the value of x

Juliette [100K]

8 + 6 + 9 + 12 + 4x / 5 = x     Original Problem.
25 + 4x / 5 = x    Addition.
25 + 4x = 5x    Multiply each side by 5.
25 = x Subtract 4x from each side.
x = 25 Switch equation around.

Answer: x = 25

What is the value of n enter your answer in the Box

brilliants [131]

The figure shows two intersecting chord, thus this simply can be solved using the Intersecting Chord Theorem, which states that "<span>When two chords intersect each other inside a circle, the products of their segments are equal."
Thus,
(15mx2m=5mxn)

n=6m</span>
