Answer:
A. 0.545454 - 1/4 = 0.295454 yes this is an irrational number
C. 3.4641016 - 1/4 = 3.2141016 yes this is an irrational number
Step-by-step explanation:
A. 0.545454 - 1/4 = 0.295454 is an irrational number as the closest fraction is shown below at 3 decimal points only
As this can be converted to a fraction 147727 /500000 ≈ 0.295
B. - 4/9 - 1/4 = -0.694444444 is not an irrational number so answer is no
As this can be converted to a fraction -173611111 / 250000000
To write 0.694444444 as a fraction you have to write 0.694444444 as numerator and put 1 as the denominator. Now you multiply numerator and denominator by 10 as long as you get in numerator the whole number.
0.694444444 = 0.694444444/1 = 6.94444444/10 = 69.4444444/100 = 694.444444/1000 = 6944.44444/10000 = 69444.4444/100000 = 694444.444/1000000 = 6944444.44/10000000 = 69444444.4/100000000 = 694444444/1000000000. Then divide by 470 and we know to use this some as 250000000/531915 = 470
C. 3.4641016 - 1/4 = 3.2141016 yes this is an irrational number
closest fraction is only 4 significant figures
4017627 / 1250000
=3 and 267627 over 12500003
267627 /1250000
≈3.214 so in closer proof it is an irrational number.
D. sq rt 4 - 1/4 = 1.75 is not an irrational number as this fraction is 7/4 = 1 3/4

Answers
Answer:
11/3 ÷ 2/3 = 5 1/2
Step-by-step explanation:
When doing divison of fractions, you do these steps
11/3 ÷ 2/3 you turn the division sign to a multiplication sign, but by doing that you will have to turn 2/3 to 3/2.
11/3 × 3/2. Now all you have to do is multiply
11/3 × 3/2 = 33/6, simplify that down is 5 3/6, which is 5 1/2

You can easily solve this equation by doing factoring (a fancy word for dividing)
so, factor out the Greatest Common Factor (GCF)
which is
B^5
so in parenthesis write (1+b^3) next to it, think of subtracting the two exponents, and then since theres only 1 thing left after factoring out b^5, you leave a 1 behind.
b^5(1+b^3)
from here, in the parenthesis, you have 2 perfect cubes, 1 and b^3
take the cube root of that which is (1+b)
then use (a+b) which is already done
AND (a^2-ab+b^2) where a is equal to 1, and b is equal to variable b.
so, that would be
x^5(1+x)(1-1x+x^2) ( this is what you should get once you do multiply the square root out to just get constants and coefficients.
That gives us our final answer of x^5(1+x)(1-1x+x^2) because it is in the simplest form possible.

Here is trapezoid A in the coordinate plane:
If you drew Trapezoid B, the image of A after a 90\circ∘ rotation clockwise, using the origin as the center of rotation, what would be the coordinates of each of the vertices?
Answers
Answer:
(1,-2) (3,-2) (4,-4) (1,-4)
Step-by-step explanation:
First of all I noted that the origin would be the centre of rotation.
Then I chose a point of Trapezoid A: I selected the point closest to the centre of rotation which was (2,1) , since that is the easiest one to do. However, this works for any point
Then I drew a line from the point (2,1) to the centre of rotation (the origin)
From the origin I then drew another line perpendicular (at a right angle to) the line that I previously drew (between the origin and point (2,1)). I drew this line so that it was also the same length as the previously drawn line and I drew it in the direction of rotation which was clockwise i.e., to the right. This line therefore went from the origin to point (1,-2).
I have now deduced that the point (1,-2) is the same as point (2,1) but in the rotated Trapezoid B.
From there I simply just rotated shape A 90 degrees clockwise so that I knew what the shape would look like if it was rotated.
Then I just drew in the other points to make the rest of the shape.
Sorry if this is hard to understand. I would be able to explain better if I was able to draw this out for you

Given that,
To determine the coordinate of the given trapezoid after the 90° clockwise rotation with origin as the center of rotation.
The graph is a demonstration of curves which gives the relationship between the x and y-axis.
Here,
Intial coordinates of the trapezoid, (1,2) , (3, 2), (4, 4) and (4, 1)
After the rotation of 90° clockwise, the trapezoid is translated to the 4 quadrants and the new coordinates are (1, -2) (3, -2) (4, -4) (1, -4).
Thus, the final coordinates are, (1, -2) (3, -2) (4, -4) (1, -4).

This is very easy. First of all you need to workout out 1/10 of the value of the 9 in 296. The value of the 9 in 296 is 90.
1/10 of 90 is 9 (since 1/10 x 90 = 90/10 = 9)

Answers
Answer:
20%
Step-by-step explanation:
Step 1: Start by changing the fraction to a decimal by diving the numerator by the denominator (1 divided by 5). That equals 0.2.
Step 2: Change the decimal to a percent by multiplying it by 100%, or moving the decimal two places. That gives you 20%.
Another way of thinking about it is multiplying the numerator by 100%, then dividing that by the denominator (100% divided by 5). This gives you 20%.
Answer: 20%

When this 3-digit number is rounded to the nearest hundred it rounds down to 600. The digit in the ones place is the third odd number that you count beginning with 1. The sum of the digits is 13. What is the number?
Answers
Answer:
1. rounds down to 600 = 601 - 649
2. The digit in the ones place is the third odd number that you count beginning with 1. = 605
3. The sum of the digits is 13
Answer:
625
Step-by-step explanation:
Firstly, I found the ones place because I just needed to know the third odd number starting from 1. The first odd number is 1 then 3 and then 5, so I know that the digit in the ones place is 5.
Ones place: 3rd odd number: 1, 3, 5
Then, I looked at the hundreds place, because I know that it is rounded to down to 600 in the nearest hundred, I know it has to be 649 or smaller and bigger than 600. In the range of 600-649, the hundreds place remains the same, and therefore I know that the digit in the hundreds place is 6
Finally, to determine the tens place, I can do 13-(6+5) I can do this because I know that the sum of the digits is 13. Because 13-11=2, I know that the digit in the tens place is 2
Final number: 625

2/9 +5/12 -7/18
Answers
Answer:
1/4
Step-by-step explanation:
Step 1 : Find a common denominator. We will use 36 as the denominator since 9, 12, and 18 are all factors of 36.
Step 2 : The number you multiple the denominator by must be the same number you multiply its numerator by.
Example : 2/9 To get a denominator of 36 you need to multiply 9 by 4. Now you need to multiply 2 by 4 as well.
Step 3 : Convert fractions into the new fractions
2/9 (times 4 on both sides) = 8/36
5/12 (times 3 on both sides) = 15/36
7/18 (times 2 on both sides) = 14/36
Step 4 : Plug new numbers into the equation.
8/16 + 15/36 - 14/36
Step 5 : Solve
8/16 + 15/36 = 23/36
23/36 - 14/36 = 9/36
Step 6 : Simplify
9/36 (divide by 9 on both sides) = 1/4
