Dentify the number that does not belong with the other three. Explain your reasoning. (4 points) negative 10 over 2, negative 13.4, square root 18, 22.7 repeating 7

Hence Sqrt(18) is different from other 3 numbers.

Step-by-step explanation:

Given:

Four numbers as:

To find :

Which one of them is different from others?

Solution:

So consider the written form,

By applying that rational number p/q form where q not equal to 0 .

we should write every number in this form otherwise it will be irrational ot not prefect square.

So

1)-10/2=-5 which can written as

-5/1=p/q form  (rational number )

2)-13.4=-(13+0.4)

=13+2/5=69/5

which is p/q form rational number

3)22.77777

=22+0.7777

=22+7/9

=205/9.

which is p/q form rational number

4)sqrt(18)

which is no prefect square its value after decimal point will not stop at particular point it will go on.

hence Sqrt(18) is irrational number .

Sqrt(18) is irrational number .

Step-by-step explanation:

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
