Select all angles that MUST be supplementary to 9

Answer:

B and C

Step-by-step explanation:

Both B and C

B)

2/5 = 0.4 (which terminate as decimals)

Similarly

C)

-1/4 = -0.25 (also terminates)

But A and D do not terminate

As for A) 1/3= 0.33333333..........

and for D) 7/9= 0.777777777......

In both cases the decimals are a never ending sequence or in other words does not terminate at all. They are irrational numbers.

Hope you understand. Thank you.

Answer:

5,212.5 rupees

Step-by-step explanation:

If price of 1 kg is 104.25

multiply 50 by 104.25

equals 5,212.5 rupees

Answer:

5212.50 rupees

Step-by-step explanation:

We can use a ratio

1 kg             50 kg

-----------  = ---------------

104.25            x

Using cross products

1x = 50 * 104.25

x =5212.50 rupees

Answer:

y= -2x+6

Step-by-step explanation:

use point slope form ----> y-y,=m(x-x,)

(the commas serve as ones)

y-4= -2(x-1)

use distributive property

y-4= -2x+2

add 4 to each side

y= -2x+6

Answer:

x = 2/3

Step-by-step explanation:

2(x-2/3)=0

Step-by-step explanation:

x²=16

x=√16

x=4

Answer:

x^2=16

^ stands for power or exponent

so, the equation is: x square= 16

for this x should be equal to 4

now,

Answer:

<A = 117degrees

Step-by-step explanation:

<A and <B are verticle angles, as given. Hence they will be of equal measures. It is given that <A = 5x -3, and <B = 4x + 21.

Using this, set up an equation;

<A = <B

5x - 3 = 4x + 21

Inverse operations,

5x - 3 = 4x + 21

    +3          +3

5x = 4x + 24

-4x   -4x

x = 24

Now substitute back in, to find the measure of <A,

5x - 3

x = 24

5 ( 24 ) - 3

120 - 3

Answer:

r = 11

Step-by-step explanation:

Is the question

r - 4 = - 3 + 10

So what's r

r - 4 = -3 + 10      Combine the right

r - 4 =  7              Add 4 to both sides

r - 4 + 4 = 7 + 4

r = 11

Step-by-step explanation:

. We assume, that the number 10 is 100% - because it's the output value of the task.

2. We assume, that x is the value we are looking for.

3. If 10 is 100%, so we can write it down as 10=100%.

4. We know, that x is 0.034% of the output value, so we can write it down as x=0.034%.

5. Now we have two simple equations:

1) 10=100%

2) x=0.034%

where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:

10/x=100%/0.034%

6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 0.034% of 10

10/x=100/0.034

(10/x)*x=(100/0.034)*x - we multiply both sides of the equation by x

10=2941.1764705882*x - we divide both sides of the equation by (2941.1764705882) to get x

10/2941.1764705882=x

0.0034=x

x=0.0034

now we have:

0.034% of 10=0.0034

Answer:

13

Step-by-step explanation:

First find the population of city c 1,070,000 times 2 = 2140000

Round 2140000 to the nearest hundred thousands = 2,100,000

Third find how many places the decimal moves which is 6 places

Fourth scientific notation of 2,100,00 is 2.1 times 10^6

Fifth divided city c by the population of city a

2.1x 10^6 divided by 1.6 x 10^5

2.1 / 1.6 rounded is 1.3

10^6 divided by 10 ^ 5 is 10

Therefore 2.1 x 10^6 divided by 1.6 divided by 10^5 equals 1.3 times 10 = 13

The population of city c is about 13 times the population of city a

Answer:

I want to say it is 8,000

Step-by-step explanation:

go to 80 degrees and go up to the next point and that is on 8,000

Answer:

8,300

Step-by-step explanation:

If you continue the graph to 80 degrees, your average will end up at 8,300. You can tell because it will be above 8,000 but not close to 9,000 so it has to be 8,300.

Answer:

Step-by-step explanation:

As the given triangle is equilateral as all the sides of the triangle are equal.

[tex]MN = 3x-8[/tex]

[tex]NO=2x-1[/tex]

[tex]OM=5x-22[/tex]

As all the sides are equal, i.e.

[tex]MN=NO=OM[/tex]

as

[tex]MN=NO[/tex]

[tex]3x-8=2x-1[/tex]

Add 8 to both sides

[tex]3x-8+8=2x-1+8[/tex]

[tex]3x=2x+7[/tex]

[tex]x=7[/tex]

Hence, the value of x = 7

so putting the value of x to determine the lengths of the

segments MN, NO, and MO

[tex]MN = 3x - 8[/tex]

       [tex]= 3(7)-8[/tex]

       [tex]=21-8[/tex]

       [tex]=13[/tex]

Hence, the length of MN = 13

[tex]NO = 2x-1[/tex]

       [tex]=2(7)-1[/tex]

       [tex]=14-1[/tex]

       [tex]=13[/tex]

Hence, the length of NO = 13

[tex]OM = 5x-22[/tex]

      [tex]= 5(7)-22[/tex]

      [tex]= 35-22[/tex]

      [tex]=13[/tex]

Hence, the length of OM = 13

Answer:

No solutions (roots)

Step-by-step explanation:

The root of an equation is basically the solution of the equation. If I'm reading the problem correctly, the equation is (6+x)*2 - x*2 = 168.

We distribute the (6+x)*2 part and get 12+2x - 2x = 168. Uh oh.. the 2x terms cancel each other out and we are left with 12=168. Either I'm reading the equation wrong or the equation has no solutions.

Answer:

4 x 13

Step-by-step explanation:

GCD of 28 and 24 is 4

28 = 4 x 7

24 = 4 x 6

u take the 4 out

4 (7 + 6)

4 x 13

The product of two factors using the GCF and the distributive property is 4(13).

The largest integer of highest degree that is an exact divisor of each of two or more integers.

The greatest common divisor of 24 and 28

24=2×2×2×3

28=2×2×7

We can see that the 2 and 2 is common in 24 and 28

The GCD of 28 and 24 is=2×2= 4

For the distributive property we have

28 = 4 x 7

24 = 4 x 6

we take the 4 out

4 (7 + 6)

=4 x 13

Therefore the GCD is 4 and by distributive property product is 4(13).
