First way: x * 1.05

This computes directly what 105% of x will be.

Second way: x + (x * 0.05)

This takes x (which is 100%) and adds 5% of x to it.

Answer and Explanation:

Given : Expression $105\%\text{ of }x$

To find : Write two expressions that could be used to find the expression?

Solution :

Expression $105\%\text{ of }x$

The two method that could be used to find the expression is by converting percentage into fraction or converting into decimal the result remain same.

1) Converting percentage into fraction,

$105\%\text{ of }x$

$=\frac{105}{100}\times x$

$=\frac{105x}{100}$

$=1.05x$

2) Converting percentage into decimal,

$105\%\text{ of }x$

$=1.05\times x$

$=1.05x$

Consider the following theorem and proof.Theorem: The number âš2 is not rational number.Proof: Let's suppose âš2 is a rational n

Answer:

The statement "Both of the numbers a and b cannot be even." is justified by the fact that a/b is simplified lowest terms

Step-by-step explanation:

We need to show that the √2 is an irrational number.

And from the given steps of proof stated in the question, we need to find the assumption that justifies the fact : " Both of the number a and b cannot be even".

First take the given options :

Option a : √2 is a rational number

√2 being an rational or irrational has no relation of a and b to be even or odd. So, this option is rejected.

Option B : a/b is simplified lowest terms

This shows that a and b are not even because if a and b are even then a/b can be simplified in other lowest term.

Option c : √2 is a irrational number

Similarly, By using the inverse part of Option A, option c is also rejected.

Option d : The fact that b divides a evenly

This only shows that the a is even. This does not give any idea about b is even or not. So option D is also rejected.

Option E : The fact that a and b are whole numbers

This fact does not imply that the a and b are even or odd. So option E is also rejected.

Hence, The statement "Both of the numbers a and b cannot be even." is justified by the fact that a/b is simplified lowest terms

nordsb [41]

Answer:

the students that brought a lunch box is 28

Step-by-step explanation:

The computation of the students that brought a lunch box is shown below:

= Entire school students × students that carry a lunch box ÷ entering students

= 84 students × 8 ÷ 24 students

= 28 students

Hence, the students that brought a lunch box is 28

The price of an item has dropped to $39 today. Yesterday it was

Kobotan [32]

Answer:

40% decrease

Step-by-step explanation:

First, let's find the value decrease of the item from yesterday to today

$65 - $39 = $26

That means that $65 was 100% of the price and decreasing it by 26 gets us to 39

We need to find the percentage of 39 in 65

39/65 = 0.6 or 60%

If 39 is 60% of 65, then there was a 40% decrease form 100%

To check we can calculate the percentage of 26 in 65:

26/65 = 40%

There was a 40% decrease

Given:

Point (7,12) is rotated 1260° counterclockwise about the origin.

To find:

The x-coordinate of the point after this rotation.

Solution:

If a point is rotated 360 degrees then its coordinates remains unchanged.

If a point is rotated 180 counterclockwise about the origin degrees, then

$(x,y)\to (-x,-y)$

We know that,

$1260^\circ=1080^\circ+180^\circ$

$1260^\circ=3\times 360^\circ+180^\circ$

After $3\times 360^\circ$ rotation the coordinates of points remains same, i.e., (7,12). So, after that (7,12) is rotated 180° counterclockwise about the origin.

$(7,12)\to (-7,-12)$

The point (7,12) becomes (-7,-12) after rotation of 1260° counterclockwise about the origin.

Therefore, the x-coordinate of the required point is -7.
