Find the sum of 2√5 AND 4√3 in simplest form. Also, determine whether the result is rational or irrational and explain your answer.

Answer:

Plot and Draw a line through the coordinates I tell you do.

(0,2), (5,1)

Step-by-step explanation:

Answer:

Let 3x+32 - be the complement angle

x - be the angle

Therefore,

3x+32+x = 90

4x = 58

x = 14.5°

and the compliment is, 75.5°

Hope that helps!

Answer:

D. WV

Step-by-step explanation:

A ray has one endpoint and one arrow. It goes infinitely in one direction.

D is the one that is a ray; the endpoint is on the left, the arrow is on the right.

b)

[tex] \frac{42}{0.21} = \frac{4200}{21} = 200[/tex]

c)

[tex] \frac{200}{0.5} = \frac{2000}{5} = 400[/tex]

I hope I helped you^_^

Step-by-step explanation:

[tex]here \: c \: is \: the \: \: mid \: point \\ so \: bc = cd \\ 6x - 16 = 4x + 10 \\ x \: terms \: togather \\ 6x - 4x = 10 + 16 \\ 2x = 26 \\ x = \frac{26}{2} \\ x = 13 \\ thank \: you[/tex]

Answer:

x=13

Step-by-step explanation:

BC = CD

6x-16 = 4x+10

Subtract 4x from each side

6x-16-4x = 4x+10-4x

2x-16 = 10

Add 16 to each side

2x-16+16 = 10+26

2x = 26

Divide by 2

2x/2 =26/2

x = 13

Answer:

3x^2+5x+2

Step-by-step explanation:

(3x^2)+(2x)+(3x)+(2)

3x^2+5x+2.

Answer:

3x²+5x+2

Step-by-step explanation:

(x+1)(3x+2)

(3x²)+(2x)+(3x)+(2)  

3x²+5x+2.

Step-by-step explanation:

Let the angles of quadrilateral be

X, 2x, 3x, 4x

Sum of all angles of quadrilateral = 360

X+2x+3x+4x = 360

10x = 360

X = 360/10 = 36

Ans: the four angles are

X = 36

2x = 2 X 36 = 72

3x = 3 X 36 = 108

4x 4 X 36 = 144

Answer:

It is 6/30

Step-by-step explanation:

This is because when you simplify 6/30 to the lowest form, you get 1/5

Answer:

There are a lot of fraction that can be equal to the values given above. It can be as follows:

 1/5 = 2/10, 3/15, 4/20, 5/25, 6/30, 7/35,8/40

4/7 = 8/14, 12/21, 16/28

6/30 = 12/60, 18/90, 24/120

5/15 = 1/3, 10/30, 20/60

Answer:

10 shirts

Step-by-step explanation:

We can use a ratio to solve

50 dollars           125 dollars

-------------------- = -------------------

4 shirts                   x shirts

Using cross products

50 *x = 4 * 125

50x = 500

Divide each side by 50

50x/50 = 500/50

x = 10

Answer:

D. 10

Brainliest, please!

Step-by-step explanation:

50/4 = 125/x

25/2 = 125/x

25 = 250/x

x = 250/25

x = 10

Answer:

17

Step-by-step explanation:

You need to add 4 degrees to get to 0.

You need to add 13 degrees to get to 13

The total = 4 + 13 = 17                      

Answer:

1) 43/40

2) 35/6

3) 43/40

4) -5/3

5) 1/6

Step-by-step explanation:

1)  -1 4/5 = -(1*5 +4)/ 5= -9/5

or          1= 5/5  so -1 4/5= -( 5/5+ 4/5)=-9/5

-2 7/8= -(2*8+7)/8=-23/8

=> -9/5 - ( -23/8)= -9/5 + 23/8 = (( -9*8)+(23*5))/40= (-72+ 115)/40

                                                                                =  43/40

2) 4 3/4= (4*4+3)/4= 19/4

-1 1/12= -(1*12+1)/12= -13/12

=> 19/4 - (-13/12)= 19/4 + 13/12 = ((19*3)+13)/12= (57+13)/12= 35/6

3) same like 1)

4) 3 1/3 = (3*3+1)/3= 10/3

=> 10/3 -5= (10- 3*5)/3= (10-15)/3= -5/3

5) -1/3 + 1/2= ((-1*2)+(1*3))/6 = (-2+3)/6= 1/6

Answer:

11,4 > 11 > 9,8 > 1

Step-by-step explanation:

To list the numbers from smallest to largest we need to determine the value of them in same/similar format

11 and 1 is in same format

The approximate value of [tex]\pi ^{2}[/tex] 9.8

the root of [tex]\sqrt{121}[/tex] = 11

the root of  [tex]\sqrt{130}[/tex] is = 11.4 approximately

Now we have them as real numbers we can evaluate

11,4 > 11 > 9,8 > 1 we don't need to write 11 twice but if needed we can write is as:

11,4 > 11 = 11 > 9,8 > 1

Step-by-step explanation:

The distance from the center of a circle to any point on the circumference must be equal.

Answer:

A. 9x=72

Step-by-step explanation:

9 times exavior = 72

Xavior is X

9x=72

9x/9=72/9

x = 8

Answer is A

Answer:

5

Step-by-step explanation:

The pythagorean theorem

A^2+B^2=C^2

A^2 =12^2

b^2 is what you need to find

C^2= 13^2

so it's

144+B^2=169

-144         -144

B^2=25

square root of 25 is 5 which is the answer

Answer:

D(1,4) - the fourth vertex, the area is equal to 12

Step-by-step explanation:

A(2,-1), B(1,0),C(4,3), They are consecutive, we need to find the point D, find the midpoint of AC (O)

xo= (xA+xc)/2    x0= (-2+4)/2=1

y0=(yA+yC)/2    y0= (1+3)/2=2

0(1,2)

O is the midpoint of BD, so let's find the vertex D

X0= (xB+xD)/2     1= (1+xD)/2   xD=1

y0= (yB+yD)/2      2= (0+yD)/2    yD=4

D(1,4)

the vector DA is (-2-1, 1-4)= (-3,-3)

the vector DC is (4-1, 3-4)= (3,-1)

The modul of DC is sqrt ((-3)^2+(-3)^2)= 3*sqrt2(the length of the side Dc)

The modul of DA is sqrt (3^2+(-1)^2)= sqrt10(the length of the side DA)

cosD= (-3*3+(-3)(-1))/3*sqrt2*sqrt10=-6/3*2*sqrt5=-1/sqrt5

sinD= sqrt (1- 1/5)=2/ sqrt5

S=3sqrt2*sqrt10*2/sqrt5= 12

Step-by-step explanation:

Hey there! I'm happy to help!

Train X takes out 1/4 of our journey.

Now, we have 3/4 of the journey left.

Train Y takes 3/4 of the last 3/4 of the journey. How much is that, let's just multiply the fractions!

3/4*3/4= 9/16

So, 9/16 of the total journey is done by Train Y.

A fourth of 16/16 is 4/16, so that leaves us with 3/16 left to go.

So, 3/16 of our total distance is equal to 10 km. Let's call our total distance d and set this up as an equation.

3/16d=10

Divide both sides by 3/16.

d= 53 1/3

We also remember that Train Y gave us 9/16 of our total journey, so we can multiply this by our total distance to see how far train Y went.

53 1/3 * 9/16= 30

So, A. Ahmad traveled 30 miles by Train Y and B. his total distance traveled is 53 1/3 miles.

Have a wonderful day and keep on learning! :D

Answer:

2.8 and 4.4

Step-by-step explanation:

The distance between tick marks is 0.25.

Since the first number is greater than 2.75, we can approximate is as 2.28.

The second number is less than 4.50, we can approximate it as 4.4.
