Answers

Answer 1

Answer:

Answer: -9<x<4

Step-by-step explanation:

/ 2x +5/ < 13 , the first thing is to remove the absolute symbol , which will be

-13 < 2x + 5 < 13

solving the first part:

-13 < 2x + 5

-13 - 5 < 2x

-18 < 2x

-9 < x

solving the second part

2x + 5 < 13

2x < 13 - 5

2x < 8

x < 4

combining the two results

-9<x<4

How to write 80a^3/4 in radical form

Answers

easy peasy
ok so remember
$x^{ (m)/(n) } = \sqrt[n]{x^(m)}$
so
$80a^{ (3)/(4) } = \sqrt[4]{80a^(3)}$
80=2^4*5
$80a^{ (3)/(4) } = 2\sqrt[4]{5a^(3)}$

A plane slices diagonally through a rectangular prism as shown. Which term best describes the cross-section formed by the intersection of the plane and the prism?

Answers

Answer:

Rectangle shaped cross section is formed by intersection of plane and prism.

Step-by-step explanation:

Given: A rectangular Prism.

To find: Shape of Cross Section when a plane intersect the prism diagonally

A plane intersect the Rectangular prism .i.e, Cuboid diagonally which means plane passes from top edge of cuboid to edge on bottom on opposite side.

Figure is attached.

In this way we get a Rectangular shaped Cross section which includes edges of cuboid and diagonals of the side faces.

Therefore, Rectangle shaped cross section is formed by intersection of plane and prism.

What is 22% expressed as a fraction in simplest form?

Answers

22% when expressed as a fraction is 22/100.
to write this in the simplest form, we have to keep dividing both numerator and denominator by a common number.
22/100 , both are divisible by 2. therefore when 22/100 is divided by 2
$(22/2)/(100/2) = (11)/(50)$
then we get 11/50. this cannot be divided any further by a common factor to both. therefore simplest form is 11/50

11/50 is 22% expressed as a fraction in simplest form.

Here, we have,

22% when expressed as a fraction is 22/100.

to write this in the simplest form, we have to keep dividing both numerator and denominator by a common number.

22/100 ,

both are divisible by 2.

therefore when 22/100 is divided by 2

we get,

22/2 / 100/2

=11/50

then we get 11/50.

this cannot be divided any further by a common factor to both.
