the diameter of a circle is 10 yards. find the approximate circumference for the circle, using 3.14 for pie.

Answer:-4<x<=5

Step-by-step explanation:

The white dot is above -4 and the filled in dot is above 5. Put that together plus the correct inequality signs and you get -4<x<=5

Answer: [tex]-4 < x\leq 5[/tex]

Step-by-step explanation:

The inequality ends at 4 and it is colored white so x must be greater than -4 therefore the first expression is x > -4 or -4 < x.

The other side of the inequality ends at 5 and it's colored black so x is less than or equal to 5. Therefore the second expression is [tex]x\leq 5[/tex].

if we merge the two equations together than we would get [tex]-4 < x\leq 5[/tex].

Step-by-step explanation:

you need to make 5 3/4 into an improper fraction

(5x40)+3/4= 23/4

make all fractions have a common denominator

1/2 = 2/4    

you multiply numerator and denominator by 2 to get a denomintator of 4

23/4 ÷ 2/4

to divide a fraction you turn the second fraction into a reciprocal

2/4 in a reciprocal is 4/2

then you multiply the fractions together

23x2/2x4

Break even 126 units

105x - (90x + 1890)  Profits will be revenue minutes expenses.

The second answer.

Step-by-step explanation:

105x = 90x +1890  Subtract 90x from both sides

15x = 1890  Divide both sides by 15

x 126

They need to sell 126 units to break even.

105(91) -[90(91) + 1890]

9555-8190-1890

9555 - 16380

-6825

Selling 91 units will produce a loss of 6825

Correct option is third option - " the original amount of the loan "

x value would be the time in months and y value would be the loan amount that is left.

The y-intercept is basically the point where x is 0. So, we can say the y-intercept would be when time is 0.

That's basically when the loan started and the y-value represents the full loan amount., which is $22,000.

correct option is third option -- "the original amount of the loan".

The standard error of the mean is approximately 0.79 (rounded to two decimal places).

Define standard error ?

The standard error is a statistical term that measures the variability of a sample mean or an estimate of a population parameter from its true value. It is the standard deviation of the sampling distribution of the mean. In simpler terms, the standard error measures how much the sample mean varies from the true population mean. A smaller standard error indicates that the sample mean is more likely to be representative of the population mean, while a larger standard error suggests that the sample mean may not be as reliable.

The formula for the standard error of the mean is:

[tex]SE = \frac{\sigma }{\sqrt{n}}[/tex]

Where σ is the population standard deviation and n is the sample size.

Substituting the given values:

[tex]SE =\frac{5}{\sqrt{40}}[/tex]

SE ≈ 0.79

Therefore, the standard error of the mean is approximately 0.79 (rounded to two decimal places).

The value of x for the given triangle is 2 units.

According to the question,

We have the following information:

We have a figure of triangle where a line segment is dividing the two sides. The measurement of some of its sides are given.

Now, the side with measurement 12 units and one divided side is 4 units.

The next side to 4 units in the same side will be (12-4) units or 8 units.

Now, using the basic proportionality theorem, we have the following expression:

6/6x = 4/8

Using the cross multiplication method:

6x*4 = 8*6

x = 48/24

Answer: The answer to this question would either be 8 or it would be 7.

Answer:

I believe that these are the answers.

Step-by-step explanation:

1. 2(6+4x)=8x+6    No Solution

2. 2(4x − 2) = 10x – 6  x=1

3. 7+x=2x+6    x=1

4. 2x+2=-2(1-x)   No Solution

Hope this helps

Answer:

Step-by-step explanation:

2(6 + 4x) = 8x + 6

12 + 8x = 8x +6

12 -6 + 8x = 8x + 6 -6

6 + 8x = 8x

6 + 8x - 8x = 8x -8x

6 = 0

no solution

2(4x -2) = 10x -6

8x -4 = 10x -6

8x - 4 +4 = 10x -6 +4

8x = 10x - 2

8x - 10x = 10x -10x -2

-2x = -2

-2x/-2 = -2 /-2

x = 1

7 + x = 2x +6

7 -6 + x = 2x +6 -6

1 + x = 2x

1 + x -x = 2x -x

1 = x

2x + 2 = 2(1 - x)

2x + 2 = 2 - 2x

2x +2 -2 = 2 -2 - 2x

2x = -2x

2x + 2x = -2x + 2x

4x = 0

4x/4 = 0/4

x = 0

The addition or subtraction of a constant to a function will change its position in the cartesian plane. Depending on the sign of the constant, it can shift upwards or downwards.

Let a quadratic function be f(x) = 2x^2.

Let c be the positive constant.

It is now necessary to determine what will happen if we add or subtract a constant to the function.

The function f(x) = 2x^2 is a parabola opening upwards.

Now, if we add the positive constant c, then the graph of the function will shift upwards by c units and nothing will change. If we subtract the positive constant c, then the graph of the function will shift downwards by c units.

Thus, the addition or subtraction of a constant to a function will change its position in the cartesian plane. Depending on the sign of the constant, it can shift upwards or downwards.

Define Algebraic Expression

The concept of algebraic expressions is the use of letters or alphabets to represent numbers without providing their precise values. We learned how to express an unknown value using letters like x, y, and z in the fundamentals of algebra. Here, we refer to these letters as variables. Variables and constants can both be used in an algebraic expression. A coefficient is any value that is added before a variable and then multiplied by it. In mathematics, an expression that incorporates variables, constants, and algebraic operations is known as an algebraic expression (addition, subtraction, etc.).

Given expression,

Step-by-step explanation:

slope formula: y2-y1/x2-x1

y-16/36

Numerator is supposed to equal -32 since denominator is 36

y-16=-32

 +16.  +16

y=-16

Hopes this helps,please mark brainliest

Answer:

  (b)  -16

Step-by-step explanation:

You want the y-value that goes with x=17 on the line with slope -8/9 through point (-19, 16).

The point-slope form of the equation for a line is ...

  y -k = m(x -h) . . . . . . line with slope m through point (h, k)

The line with slope -8/9 through point (-19, 16) will have the equation ...

  y -16 = -8/9(x +19)

You want the value of y for x=17. We can find that by substituting x=17 into the above equation:

  y -16 = -8/9(17 +19) = -8/9(36) = -32

Adding 16 gives the value of y:

  y = 16 -32 = -16

The line passes through the points (-19, 16) and (17, -16).

using Pythagoras' identity in the right triangle

the square on the hypotenuse is equal to the sum of the squares on the other 2 sides , that is

(k + x)² = m² + (k - x)² ← expand factors on both sides using FOIL

k² + 2kx + x² = m² + k² - 2kx + x² ( add 2kx to both sides )

k² + 4kx + x² = m² + k² + x² ( subtract k² + x² from both sides )

4kx = m² ( divide both sides by 4k )

x = [tex]\frac{m^2}{4k}[/tex]

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

(ii)

the area A of a triangle is calculated as

A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )

here b = m and h = k - x

A = [tex]\frac{1}{2}[/tex] m (k - x) ← substitute x = [tex]\frac{m^2}{4k}[/tex]

The given parameters in the question are:

Martin

Initial amount = $30

Additional earnings = $10

His friend

Initial amount = $60

The equation that shows their total earnings is

y = Initial amount + Additional earnings * x

So, we have

Martins: y = 30 + 10x

His friend: y = 60 + 7x

When Martin has more money, we have

Martins > His friend

This gives

30 + 10x > 60 + 7x
