What is the value of -2 7/12 divided -1/6

Answer:

Using trigonometry:

Let's take Tan of 60 degrees:

Tan 60 degrees = Opposite / adjacent

We can see that the opposite side is 3√3 and the adjacent side is x

Tan 60 degrees = 3√3 / x

From the trigonometric table, we know that Tan 60 degrees is √3

√3 = 3√3 / x

x = 3√3 / √3

x = 3

Now, we will take Sin of 60 degrees

Sin 60 degrees = Opposite / Hypotenuse

We can see that the opposite side is 3√3 and the hypotenuse is y

Sin 60 degrees = 3√3 / y

From the trigonometric table, we know that Sin 60 degrees is √3 / 2

√3/2 = 3√3 / y

y = 3√3 / (√3/2)

y = 3√3 * 2/√3

y = 6

Therefore, y = 6 and x = 3

Answer: the answer should be lower than because this is the percentage of people who get diagnosed with a disease that is not lupus 0.465 so about 50% or 0.5 hopefully that help I don't know the answer for the amount of people who don't have it and get misdiagnosed there is no information on it based on what I've seen  

Step-by-step explanation: Its based on a study from the Lupus Foundation of America

Answer:

ab - a - b + 1 = (a - 1)(b - 1)

Step-by-step explanation:

Let us explain factorization by grouping

In the expression of 4 terms ax + by + bx + ay

Take every two terms have a common factor in a bracket

Take the common factor out of the brackets

Take the bracket as a common factor

Let us do these steps with our question

∵ ab - a - b + 1 is an expression of 4 terms

→ Take ab and a in a bracket, -b and 1 in another bracket

∴ ab - a - b + 1 = (ab - a) + (-b + 1)

→ Take a as a common factor from the 1st bracket and -1 from

   the 2nd bracket

∴ (ab - a) + (-b + 1) = a(b -1) + -1(b - 1)

→ Take the bracket (b - 1) as a common factor

∴ a(b -1) + -1(b - 1) = (b - 1)(a + -1)

∵ (+)(-) = (-)

∴ (b - 1)(a + -1) = (b - 1)(a -1)

→ Change the order of the bracket

∴ (b - 1)(a -1) = (a - 1)(b - 1)

∴ ab - a - b + 1 = (a - 1)(b - 1)

Counterexample for the numbers 25 and 10

The actual LCM is 50

If you were to multiply both numbers together you would get 250 which is incorrect

Answer:

is it two m plus eight m?

Answer:

40%

Step-by-step explanation:

It went down by 10 ml.

40% of 25 is 10, so te answer would be 40%

Answer:

60%

Step-by-step explanation:

Part/whole method:

[tex]\frac {15} {25} = \frac {p} {100}[/tex]

15·100=1,500

1,500÷25=60

15 is 60% of 25

Step-by-step explanation:

Answer:

im pretty sure it has two real solutions

Step-by-step explanation:

1. simplify the equation given

  (4x - 6)(x + 5) = 15

     4x^2 + 20x - 6x - 30 = 15

        4x^2 + 14x - 45 = 0

2. find the discriminant (b^2 - 4ac); (a = 4, b = 14, c = -45)

  14^2 - (4 x 4 x -45)

     196 - (-720)

        916

  the discriminant is positive, so this equation has 2 real solutions

to find the solutions, factor the bolded equation (if you need help factoring, let me know!)

Answer:

$898

Step-by-step explanation:

Based on Joey's debt-to-income ratio, the maximum monthly rent payment he can make and still maintain the DTI ratio is b. $898.

Joey has a DTI ratio of 36% which means that his maximum debt payment should be 36% of his income. This amount would be:

= DTI x monthly income

= 36% x 3,600

= $1,296

This can be found as:

= Maximum monthly debt payment - Car payment - Credit card payment

= 1,296 - 178 - 220

= $898

In conclusion, option B is correct.

Answer:

Step-by-step explanation:

how, because 3 is 12, 4 is 16 because multiply by 4

Answer:

1: m=2

2: g=7

3: y=13

4: a=-27

5: x=15

6: w=-18

Answer:

1. m = -2  

2. g = 7  

3. y = 13      

4. a = -36  

5. x = 15

6.  w = -18                                                                                                                                            

Step-by-step explanation:

1. Make the constant to the right-hand side and change its sign

a = 10 - 12

Calculate the difference a = -2

Solution

a = -2

2. Move variable to the left-hand side and change its sign

-g - 2 = - 9

Move constant to the right-hand side and change its sign

-g = -9 + 2

Calculate the sum

-g = -7

Change the signs on both sides of the equation

g = 7

Solution

g = 7

3. Divide both sides of the equation by - 7

-7y ÷ (-7) = -91 ÷(-7)

Any expression divided by itself equals 1

y = 91 ÷ (-7)

Divide two negatives equals a positive: (-) ÷(-)=(+)

y = 91 ÷ 7

Calculate the quotient

y = 13

Solution

y = 13

4. Multiply both sides of the equation by 9

9 x a/9 = 9 x (-4)

Reduce the number with the greatest common factor 9

a = 9 x (-4)

Multiply a positive and a negative equals a negative: (+)x(-)=(-)

a = -9 x 4

Multiply the numbers

a = -36

Solution

a = -36

5. Multiply both sides of the equation by 3/2

3/2 × 2/3x =  3/2 × 10

Reduce the numbers with the greatest common factor 3

1/2 × 2x = 3/2 × 10

Reduce the numbers with the greatest common factor 2

x = 3/2 × 10

Reduce the numbers with the greatest common factor 2

x = 3 x 5

Multiply the numbers

x = 15

Solution

x = 15

6. Multiply both sides of the equation by 9/4

9/4 x 4/9w = 9/4 x (-8)

Reduce the numbers with the greatest common factor 9

1/4 x 4w = 9/4 x (-8)

Reduce the numbers with the greatest common factor 4

w = 9/4 x (-8)

multiplying a positive and a negative equals and negative: (+)x(-)=(-)

w = -9/4 x 8

Reduce the numbers with the greatest common factor 4

w = -9 x 2

Multiply the numbers

w = -18

Solution

w = -18

Step-by-step explanation:

multiply both by a number, kinda like a fraction.

Answer:

No, they are not equivalent

Step-by-step explanation:

Because

120/2 Can not be divided equally into 360/6

Answer:

Yes

Step-by-step explanation:

They are equivalent because if you write the ratio's out, you get 120:2 and 360:6. If you then simplify both, you get 60:1. To simplify these, you need to find a common factor. In 120:2, you can tell that both numbers can be divided by two because they are both even. After dividing, you get 60:1. In 360:6, you can tell that both numbers can be divided by 6 since they both are multiples of 6. After dividing, you get 60:1. Because these to ratio's are equal, they are equivalent.

Given parameters:

Number of pencils = [tex]4\frac{1}{2}[/tex] pencils

Time taken = [tex]3\frac{1}{3}[/tex] minutes

Unknown:

Number of pencils produced in 1 minute;

Solution:

To solve this problem, let us first find the rate of the machine;

       Rate of machine = [tex]\frac{number of pencils }{time taken}[/tex]

       Rate of machine = [tex]\frac{\frac{9}{2} }{\frac{10}{3} }[/tex]   = [tex]\frac{9}{2} x \frac{3}{10}[/tex]   = [tex]\frac{27}{20}[/tex] pencils/minute

Now, number of pencils produces in 1 minute;

            Number of pencils  = rate of machine x time taken

             Number of pencils = [tex]\frac{27}{20}[/tex]  pencils/ min x 1 min

             Number of pencils = [tex]\frac{27}{20}[/tex]pencils

The number of pencils produced in 1 minute is [tex]\frac{27}{20}[/tex]
