[tex]6\frac{1}{4}-4\frac{3}{5}[/tex]

Answers

Steps:

6 1/4 - 4 3/15 can also be written as 25/4 - 23/5

The LCD of 4 and 5 is 20.

That gives us 125/20 - 92/20.

Now, just subtract the numerators (leave the denominators the same).

That brings us to 33/20, which can be simplified to 1 13/20

Final Answer:

[tex]1\frac{13}{20}[/tex]

--------------------------------------------------------------------------------------------------------------

*Please mark brainliest if that helped!*

Answer:

1 [tex]\frac{13}{20}[/tex]

Step-by-step explanation:

1. Convert both [tex]\frac{1}{4}[/tex] and [tex]\frac{3}{5}[/tex] into a common denominator. 4 multiplied by 5 is 20. 20 works for both 4 and five. So convert the denominator into 20. Multiply [tex]\frac{1}{4}[/tex] by [tex]\frac{5}{5}[/tex] and multiply [tex]\frac{3}{5}[/tex] by [tex]\frac{4}{4}[/tex]

2. You should've gotten, [tex]\frac{5}{20}[/tex] and [tex]\frac{12}{20}[/tex]

3. 6 - 4 = 2, so 2 [tex]\frac{5}{20}[/tex] - [tex]\frac{12}{20}[/tex]

4. You have to convert 1 into [tex]\frac{20}{20}[/tex] and add that to [tex]\frac{5}{20}[/tex]. You should've got [tex]\frac{25}{20}[/tex]

5. Subtract.

The Answer is 1 [tex]\frac{13}{20}[/tex]

Which of the following appears to be a scaled copy of the original image? *
YOU CAN CHOOSE MORE THAT ONE

Answers

Answer: Third Choice. B,C, and E

Concept:

A scaled copy is a copy of a figure where every length in the original figure is multiplied by the same number.

Explanation:

Choice A. [tex]\boxed{FALSE}[/tex]

The figure given as choice A seems to be much thinner than the original image. Therefore, the figure did not copy each length in scale.

Choice B. [tex]\boxed{TRUE}[/tex]

The figure given as choice B seems to be the same size as the original image but different position. However, the position is not a concern in a scaled copy image. Therefore, the figure did copy each length in scale.

Choice C. [tex]\boxed{TRUE}[/tex]

The figure given as choice C seems to be larger than the original image and different position. However, the scale of choice C seems even to the original image. Therefore, the figure did copy each length in scale.

Choice D. [tex]\boxed{FALSE}[/tex]

The figure given as choice D seems to be larger and wider than the original image. Therefore, the figure did not copy each length in scale.

Choice E. [tex]\boxed{TRUE}[/tex]

The figure given as choice E seems to be smaller than the original image and different position. However, the scale of choice C seems even to the original image. Therefore, the figure did copy each length in scale.

Therefore, the choices would be B, C, E, which would be the third choice.

Extra: A shortcut (lazy) way to do the question

As listed above, A and D are clearly not to scale since one is much thinner, one is much wider. Therefore, we can directly neglect choices that contain A and D, which would only leave us with the third choice.

Hope this helps!! :)

The distance from P to R is 21, since 5 - (-16) = 21.

Answers

The first answer.

Point P is at (50,-40) the distance from Q to P is 80 units which you can find by subtracting the x of Q (-30) from the x of P (50).
50-(-30)=80
It then tells you point R is vertically above point Q so you know your x value for R will be the same as Q.
Add your distance from Q to P of 80 units to the y value of Q because you are traveling up.
-40+80=40
R will have a point of (-30,40) and a distance of 80 units

What is the step by step explanation on how to solve 8 1/2 + 3 4/5? I already know the answer is 12.3 but I just need help on the how to do the work.

Answers

To do this, first add the whole numbers: 8 + 3 = 11. Set that aside for a moment.

To add the fractions, 1/2 + 4/5, you need a common denominator. With 2 and 5, you’d have an LCD of 10.

1/2 = 5/10

4/5 = 8/10

So 1/2 + 4/5 = 5/10 + 8/10 = 13/10

Now, 13 is bigger than 10, so 13/10 is the same as 1 and 3/10.

We’ll add that to the 11 we found back in the beginning and get 11 + 1 and 3/10 = 12 and 3/10 or 12.3.

which number produces an irrational number when added to 1/4

Answers

π is an irrational number when it is added to 0.4 we will get an irrational number

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

The figure on the left is reflected using the y-axis to form the image on the right. Use the information in the original figure to find the measure of side A, side B, angle C and angle D.

Answers

So basically the figure is just flipped over so it’s the same thing as the other side just placed in a different spot. So angle b would be 2.2. Angle a would be 3.2. Look at the other angle and do what I did for angle b and a and you would be able to figure it out.
