c. 73°

Step-by-step explanation:

Simply GNH is 47° by vertically opposite angle of MNL

NOW,

GNF+GNH+HNK=180° [ being straight line]

60+47+HNK=180

107+HNK=180

HNK=180-107=73

Answer:

The higher the slope, the steeper it is, the faster it increases. The faster we increase in the vertical direction as we increase in the horizontal direction. The graph of an increasing function has a positive slope. A line with a positive slope slants upward from left to right as in (a).

Start with definition of absolute value, |x|.

It says, |x| = x, for any x >= 0 and

|x| = -x, for any x < 0

 Now, instead of x, we have the expression x+120 inside the absolute value brackets:

|x+120|

Play the same game as above - what is the absolute value here?

|x+120| = x+120 for (x+120)>=0 and

|x+120| = -(x+120) for (x+120)<0

Now, recognize that the last condition (x+120)<0 is the same as writing x<-120. That is the condition in the question. Therefore the absolute value |x+120| will equal the second expression (for that condition), namely -(x+120), or -x-120.

Step-by-step explanation:

The system of equations formalizes the given relationships regarding the number of coins and their value.

  x + y = 18 . . . . . . Freya has 18 coins

  0.50x +1.00y = 13 . . . . their value is £13

_____

Additional comment

The solution can be found by subtracting the second equation from the first:

  0.5x = 5

  x = 10

  y = 18 -10 = 8

Freya has 10 50p coins and 8 £1 coins.

Answer:

BC= 9.04

AC= 15.0

mark brainliest

Answer:

  BC ≈ 9

  AC ≈ 15

Step-by-step explanation:

The side adjacent to the given angle is the one whose length is known, so the relevant trig relations are ...

  Cos = Adjacent/Hypotenuse   ⇒   cos(37°) = AB/AC

  Tan = Opposite/Adjacent   ⇒   tan(37°) = BC/AB

Then the unknown sides are ...

  AC = AB/cos(37°) = 12/cos(37°) ≈ 15

  BC = AB·tan(37°) = 12·tan(37°) ≈ 9

__

Additional comment

Rounded to the nearest degree, angles 37° and 53° are the acute angles found in a 3-4-5 right triangle. Since the given side is adjacent to the smallest acute angle (not the hypotenuse), it will correspond to "4" in the 3-4-5 triangle. That means the scale factor is 12/4 = 3, and the other two sides are 3·3 = 9 and 3·5 = 15.

The numbers work out this way only by rounding to tenths or integers.

Answer:

Step-by-step explanation:

The length of a segment on a number line is the difference of its coordinates.

  AB = 9 -(-7) = 16

  CD = 12 -(-4) = 16

AB and CD both have a length of 16 units, so are congruent.

3) B    4) D

Step-by-step explanation:

3) Graph the equations and locate the intersection.

4) the best method to solve number 4 is the substitution method

6x+7y=20

y=2x

we second equation is basically telling us that y=2x so we just plug it into the first equation

6x+7(2x)=20

distribute

6x+14x=20

combine like terms

20x=20

divide each side by 20

x=1

now plug in our answer into one of the equations (does not matter which one)

y=2 times 1

y=2

meaning that our answer is (1,2), x=1  y=2

Step-by-step explanation:

5a-5b=5

a+b=3

-a     -a

b=3-a

5a-5(3-a)=5

5a-5(3)-5(-a)=5

5a-15+5a=5

10a-15=5

10a=20

a=2

2+b=3

b=1

5(2)-5b=5

10-5b=5

-5b=-5

b=1

Answer:

a = 2

b = 1

Step-by-step explanation:

5a - 5b = 5

a + b = 3

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

5(a + b = 3)

= 5a + 5b = 15

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

5a - 5b = 5

5a + 5b = 15

10a = 20

÷10    ÷10

a = 2

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

a + b = 3

2 + b = 3

-2        -2

b = 1

Learning about the connections between finding the GCF of numbers, the distributive property, multiplying polynomials, and factoring has helped me understand how to simplify and solve for equations. The distributive property taught me about how to easily simplifying equations, since the requirement is to just distribute the given to the number(s). Factoring has taught me how to make an equation easier to solve. For example, when I'm given a problem that has very large numbers, I can see if they have a GCF and this will help me solve the problem in no time!

Answer:

The GCF of numbers and distributive property work together in many ways

Answer:

25 miles, and the cost will be $37.50.

Step-by-step explanation:

Mose's charge can be represented by f(x) = 0.5x + 25, Holly's charge can be represented by g(x) = 0.3x + 30.

Set the equations equal to each other: 0.5x + 25 = 0.3x + 30.

0.2x = 5

x = 25

Substitute 25 for x: f(x) = 0.5(25) + 25 = 37.5, g(x) = 0.3(25) + 30 = 37.5.

So f(x) = g(x) at x = 25, and the output will be 37.5.

Answer:

the coefficient is 96 and the exponent is 16... should I explain how?

The solution of the expression is 2.486 * 10⁻².

Scientific Notations are used to write very small and very large numbers.

The expression is (9.2 * 10⁷ ) / (3.7 *10⁹)

The exponent rule will be applied to solve this expression

[tex]\rm \dfrac{a^m}{a^n} = a^{m-n}[/tex]

9.2/3.7 = 2.486

10⁷ / 10⁹ = 10⁻²

The solution of the expression is 2.486 * 10⁻².

To find the area of ​​different geometric figures, different mathematical formulas must be used, such as: A = Π x r², A = b x h, A = b x h, among others.

To calculate the area of ​​a circle we must use the following mathematical formula:

In this formula we have the value of π, which is equal to 3.14, and the value of r², which is equal to the radius of the circle squared. For example:

To calculate the area of ​​a rectangle it is necessary to use the following mathematical formula:

A = b × h, in this formula b is equal to the length of the base and h to the length of the height of the rectangle. For example:

To calculate the area of ​​a square it is necessary to use the following formula:

In this formula b represents the base of the base and c the length of the side of the square; we must take into account that the base and the side have the same length in a square. For example:
