Answer:

Option C                                  

Step-by-step explanation:

Given : An expression written in scientific notation in the form of a\times 10^n

Let x=a\times 10^n

To find : Which statement is not true for the expression.

Solution :10^n is a power, with a base of 10 and an exponent of "b".

''n" is associate whole number like the quantity of places the decimal "moves".


→  When the exponent "n" is positive (and not zero), the number "x" is greater than one.

→ The larger the exponent "n", the larger the number "x".

→  When the exponent "n" is negative, the number "x" is between zero and one.

→ The smaller the exponent "n", the nearer the quantity "x" is to zero.  

From the above statements we say that  Option C - Doubling n results in a doubling of the value of the expression is incorrect or not true

yan [13]

Answer:

$65.    

Step-by-step explanation:

Given:

The Store's wholesale price of a t-shirt is $50

The markup set by the store is 30%.

To find:

Calculate the retail price set by the store on the t-shirt.

Solution:

Wholesale price of a t-shirt =  $50

Markup % = 30

<em>First of all we will find the markup value with the help of markup percentage and then we will simply add the wholesale price and markup value of T-shirt</em>.

Markup value of T-shirt = 30\%\ 0f\ 50=\frac{30}{100} \times50=\frac{1500}{100} =\$15

Retail price of T-shirt = Wholesale price of a t-shirt + Markup value of T-shirt

Retail price of T-shirt = $50 + $15

Retail price of T-shirt = $65

Therefore, the retail price set by the store on the t-shirt is $65.

What is an independent variable <br><br>what is an dependent variable <br><br><br>​
N76 [4]

An independednt variable is a variable that doesnt need any support Dependent is where there is variable, but it depends on something else.

For example,

y=2x+1

y is dependent, becuase it depend on 2x+1

x is independent, beucase it doesnt need to depend on anything.

I hope someone can help me here please don't answer nonsense!​
Wittaler [7]

Answer:

  282°

Step-by-step explanation:

The measure of long arc KLM can be found by first determining the measure of short arc KM. That arc can be found using the inscribed angle theorem.

__

<h3>value of x</h3>

The inscribed angle theorem tells you the measure of arc KM is twice the measure of the inscribed angle KLM that subtends it. This relation can be used to find the value of x, hence the measure of the arc.

  2∠KLM = arc KM

  2(5x -1) = 8x +14

  10x -2 = 8x +14 . . . . . . eliminate parentheses

  2x = 16 . . . . . . . . . . add 2-8x

  x = 8 . . . . . . . . . divide by 2

<h3>measure of arc KM</h3>

The expression for the measure of arc KM can be evaluated.

  arc KM = 8x +14 = 8(8) +14 = 78°

<h3>measure of arc KLM</h3>

The total of arcs of a circle is 360°, so the measure of long arc KLM will bring the total with arc KM to 360°:

  arc KM +arc KLM = 360°

  arc KLM = 360° -arc KM

  arc KLM = 360° -78° = 282°

The measure are long arc KLM is 282°.

Let p: The whole number has one digit.
Alex73 [517]

The statement "The whole number has one digit if and only if the whole number is less than 10" is true for converse statement. Then the correct option is C.

<h3>What are converse statements?</h3>

A inverse statement is one that is derived by opposing the supposition and result of a relative clause.

Let p: The whole number has one digit.

Let q: The whole number is less than 10.

The statement "The whole number has one digit if and only if the whole number is less than 10" is true for converse statement.

If p → q, then, q → p

Then the correct option is C.

More about the converse statements link is given below.
