Kia thinks that every number has at least two factors. Which explains whether Kia is correct?
elena-14-01-66 [18.8K]

Solution:

Yes , what mathematics say that every real number has at least two factors apart from number 1 and -1.

The number zero has infinite factors.

The number 1 and -1 which is neither prime nor composite has only 1 factor i.e itself.

Prime integers  has only two factors one and itself.

Non prime integers has more than two factors.

But when you say a number apart from natural, whole and integers it includes rational ,and irrational and when we combine them The set is called Real number. .So, Yes this statement is true for rational and irrational also.

So, yes Kia is not absolutely true, but if she has written the statement in this form:  Apart from 1 and -1 , every number has at least two factors then it would have been a true statement.

The area of a trapezoid is 18 square meters. One base is 3 meters long and the other is 6 meters long. Find the height of the tr
aleksley [76]

Answer:

height = 4 meters

h = 2A / ( a +  b )

Step-by-step explanation:

Let A represent the area of the trapezoid, h, the height a, the length of one base and b, the length of the other base

Area of a trapezoid, A = ( a + b)* h / 2

Now let's slot in the given values

A= 18 sq meters

a = 3 meters

b = 6 meters

we have;

18 = ( 3 + 6 ) * h /2

18 = 9 * h /2

Cross multiply

18*2 = 9h

36 = 9h

divide both sides by the coefficient of h (9)

4 = h

therefore, h = 4 meters

To solve for h without substituting

From A = ( a + b )* h /2

cross multiply

2*A = ( a + b )* h

divide both sides by ( a + b )

2A / ( a + b ) = h

therefore,

h = 2A / ( a +  b )

What is the measure of AngleDCF? Three lines extend from point C. The space between line C D and C E is 75 degrees. The space be
gizmo_the_mogwai [7]

Answer:

  ∠DCF = 129°

Step-by-step explanation:

We assume that line CE is between lines CD and CF.

The angle sum theorem applies:

  ∠DCF = ∠DCE +∠ECF

  ∠DCF = 75° +54°

  ∠DCF = 129°

kirill115 [55]

1/8th cup of marshmallows in each mug

Step-by-step explanation:

In order to split up the 1/2 cup of marhsmallows into 4 cups, you have to divide.

To divide, 1/2 by 4, you have to multiply 1/2 by the reciprocal of 4, which is 1/4.

1/2 x 1/4 = 1/8
