Let's solve for e :

  • 9e - 7 = 7e - 11

  • 9e - 7e =  - 11 + 7

  • 2e =  - 4

  • e =  - 4 \div 2

  • e =  - 2

value of " e " = -2

\\ \sf\longmapsto 9e-7=7e-11

\\ \sf\longmapsto 9e-7e=-11+7

\\ \sf\longmapsto 2e=-4

\\ \sf\longmapsto e=\dfrac{-4}{2}

\\ \sf\longmapsto e=-2

Answer:

B. x < -1

Step-by-step explanation:

Hello!

Let's put them in order from greatest to least:

  • \{-2,-5,-9,-12\}

Given our possible inequalities, we need to find the inequality that contains all of these values.

The inequality that works is x < -1, as <u>all values are less than -1.</u>

Therefore, the answer is B. x < -1.

A height of 26 feet and a diameter of 5.6 feet. What is the volume of the geode, rounded to the nearest tenth?
7nadin3 [17]

Answer:

Therefore,

The volume of the geode, rounded to the nearest tenth is 640.1 feet³.

Step-by-step explanation:

Given:

Geode shaped approximately like a cylinder. such that

Height = h = 26 feet

Diameter = d = 5.6 feet

Radius = r =\dfrac{d}{2}=\dfrac{5.6}{2}=2.8\ feet

To Find:

volume of the geode = ?

Solution:

Geode shaped approximately like a cylinder,

So, Volume of Cylinder is given by,

\textrm{Volume of Cylinder}=\pi r^{2}h

Where,

Height = h

Radius = r

pi = 3.14

Substituting the values we get

\textrm{Volume of Cylinder}=3.14\times 2.8^{2}\times 26=640.05\approx 640.1\ feet^{3}

Therefore,

The volume of the geode, rounded to the nearest tenth is 640.1 feet³.
