I think that the D. CONE is the three-dimensional figure that will be formed when an equilateral triangle is rotated around the x-axis of the coordinate plane.

<span>A sphere is defined as the set of all points in space that are a fixed distance from a common point, the center.
</span>
<span>A cylinder is with two parallel congruent circular faces whose cross sections (taken parallel to these circular faces) are circular.
</span>
<span>A cube is a rectangular prism whose faces are squares.</span>

Answer:

option D)

Step-by-step explanation:

when a equilateral triangle  is rotated about x-axis

rotating equilateral triangle about x-axis will lead to the formation of cone in.

the height of the equilateral triangle  will represent height of the cone.

the base of the equilateral triangle will represent the circular base of the cone

and the slant height of the cone will represented by the sides.

hence, the correct answer will cone which is option D)

Answer and show work.<br><br> 1.) 9 - t = 3 (t -5) <br><br> 2.) 5 (5y + 1) =10y - 25
AlladinOne [14]

Answer:

1. 6

2. 2

Step-by-step explanation:

1. 9-t=3(t-5)

9-t=3t-15

+t +t

9=4t-15

+15 +15

<u>24</u>=<u>4t</u>

4 4

6=t

2.5(5y+1)=10y-25

25y+5=10y-25

+25 +25

25y+30=10y

-25 -25

<u>30</u>=<u>-15y</u>

15 15

2=y

Lance and Alex have 70 pencils. Lance has 4 times as many pencils as Alex. Alex's pencils are shared equally among 2 children. H
gogolik [260]


let l = lance, and a = alex.

so: l + a = 70

and l = 4a

Putting the value for l in the first equation:

4a +a = 70

5a = 70

a = 14.

So Alex has 14 pencils. And Lance has (70-14) 56 pencils.

And if each child gets half of Alex' pencils, then each child will have 7 pencils.
