If the circumference of the circle is 24 inches what is the
approximate diameter

Answer:

Perimeter:\(4x+10\) feet
Area:\(x^{2}+5x+6\) feet

Step-by-step explanation:

The perimeter is equal to 2*width +2*length. The width is x+2 and the length is x+3, therefore the perimeter is equal to 2x+4+2x+6 which equals 4x+10.
The area is equal to width*length
(x+3)(x+2)=\(x^{2}+2x+3x+6=x^{2}+5x+6\)

Answer:

Decimal = -1.375, Fraction = -11/8

Step-by-step explanation:

Decimal:

-2.25 + 0.4x = -2.8

0.4x = -0.55

x = -1.375

Fraction:

-9/4 + 2/5x = -14/5

-45/20 + 8/20x = -56/20

8/20x = -11/20

x = -11/8

Here, we must use one sample z test for the first question.

Since the population standard deviation is known in this instance. According to the new protein powder firm, it takes an average of 7 days to add 10% more muscle, with a population standard variation of 5.5 days.

Here, keep in mind that the t test should be used if the population standard deviations are unknown and the z test should be used if the population standard deviations are known.

The second question requires that we test the hypothesis to determine whether the MoCA test differs between the days before and after several exposures to a new tool.

Here, a z-test with two samples was utilized. Once the hypothesis has been stated, the z Statistic

Answer:

\(\dfrac{5}{48}\)

Step-by-step explanation:

\(\left(\dfrac{5}{8} - \dfrac{1}{2}\right) \times \dfrac{5}{6}\)

First, represent 1/2 as 4/8.

\(\dfrac{1}{2} \times \dfrac{4}{4} = \dfrac{4}{8}\)

\(\left(\dfrac{5}{8} - \dfrac{4}{8}\right) \times \dfrac{5}{6}\)

   45x² - 42x + 9=0 is a simplified expression for the perimeter of the rectangle.

What is a rectangle, exactly?

A rectangle is an instance of a quadrilateral with opposing sides that are both equal and parallel. It has four sides, making it a four-sided polygon, and four angles at 90 degrees. Rectangles are examples of two-dimensional forms.

                             The closed, 2-D form of a rectangle has four sides, four corners, and four angles that are 90 degrees correct. The two sides of a rectangle are parallel and equal. Given that rectangles are two-dimensional objects, their distinctive features are length and breadth.

A rectangle has a width = 5x/x+3 units

an area = 40x²/x²-9 square units.

Area of rectangle = length * width

                40x²/x²-9  =   length * 5x/x+3

                 40x² /(x-3) (x + 3)  = length * 5x/x + 3

                   40x² * (x + 3 )/5x * (x+ 3) (x - 3) = length

                       8x/(x - 3 ) =  length

perimeter of rectangle = 2( l + w )

                              = 2(8x(x+ 3) + 15x(x - 3))/x² - 9

                              = 2(8x² + 24x + 15x - 45x )/x² - 9

                            = 2(23x² - 21x)/x² - 9

                     x² - 9   = 46x² - 42x

                     45x² - 42x + 9=0

A repeating decimal is acceptable to use during calculations when you require a certain level of precision

A repeating decimal is acceptable to use during calculations when you require a certain level of precision, but it's important to keep in mind that the result will be an approximation rather than an exact value.

It is commonly used in situations where a rounded value is sufficient and the level of precision doesn't significantly impact the final result.

On the other hand, you should convert a repeating decimal to a fraction for calculations when you need an exact value or when further mathematical operations or comparisons are required.

Converting a repeating decimal to a fraction allows for precise calculations and eliminates any potential rounding errors associated with working with decimal approximations.

Converting a repeating decimal to a fraction involves identifying the repeating pattern and expressing it as a fraction. This allows for exact calculations and maintains the mathematical properties of fractions.

By finding all the four slopes, we can see that the word is ECHA.

We know that the general linear equation can be written as:

y = a*x + b

Where a is the slope and b is the y-intercept.

We know that if the line passes through (x₁, y₁) and (x₂, y₂) then the slope is:

s = (y₂ - y₁)/(x₂ - x₁)

With that formula we can get the slopes.

1) Using the points (0, 3) and (2, 4).

m = (4 - 3)/(2 - 0) = 1/2, so the letter is E.

2)Using (-1, -12) and (1, -8)

m = (-8 + 12)/(1 + 1) = 4/2 = 2, so the letter is C.

3) We have (2, -6) and (-4, -3) so:

m = (-3 + 6)/(-4 - 2) = 3/-6 = -1/2, so the letter is H

4)we can use the points (0, 3) and (1, 1), so:

m = (1 - 3)/(1 - 0) = -2, so the letter is A

Then the word is ECHA

Answer:2100

Step-by-step explanation:

The equation of the line in slope-intercept form is: y = -25x + 100. A negative slope indicates that the battery percentage is decreasing over time.

Part A:

To write the equation of a line in slope-intercept form, we need to know the slope (m) and y-intercept (b) of the line.

From the given information, we know that the y-intercept is 100 and the x-intercept is 4. This means that after 4 hours, the battery percentage is 0%.

To find the slope, we can use the slope formula:

m = (y2 - y1)/(x2 - x1)

Choosing two points on the line, one being the y-intercept (0,100) and the other being the x-intercept (4,0), we can plug in the values:

m = (0 - 100)/(4 - 0) = -25

Therefore, the equation of the line in slope-intercept form is:

y = mx + b

y = -25x + 100

Part B:

To determine the equation, we used the fact that the y-intercept was 100 and the x-intercept was 4. We then found the slope of the line using the slope formula with two points on the line. Plugging the slope and y-intercept into the slope-intercept form equation y = mx + b gives us the final equation.

Part C:

The slope of the line is -25, which means that for every hour that passes, the battery percentage decreases by 25%. Therefore, the slope represents the rate of change of the battery percentage with respect to time. A negative slope indicates that the battery percentage is decreasing over time.

We need to replace each letter with the required numbers (a with 2 and b with 4) in the expression they gave us,and then apply the orders for operation that are critical in math evaluation.

So first we write:

whre we have repkaced each letter by its value, making sure we use a parentheses to call the attention on the new values we are using.

Now we proceed using the order of operations that are simplified in the following pnemonics: PEMDAS.

P stands for "parenthesis" so we understand that first we need to solve whatever is in parenthesis in the original expression

E stands for "exponents", so they should ge next

MD stands for multiplications and divisions, which should go next

and finally AS which stands for "additions and subtractions" that go the very last in using operations between numbers.

So let's start by trying to address what is withing parenthesis in the first expression:

Here we have used that inside the parenthesis we had a product 3 times (4) that needs to be addressed first before doing the subtraction. So we did 3 (4) = 12 and then subtracted 12 from the number 2, obtaining a negative number "-10"

The equivalent ratios are 8: 6 and 12:9.    

Two ratios are equivalent if they represent the same proportion or relative size. To find an equivalent ratio, we can multiply both terms of the ratio by the same non-zero number. This doesn't change the condition between the two terms.  

Here we have 4:3

To find equivalent ratios, we can multiply both terms by the same number.

Multiplying by 2

=> 4 × 2 : 3 × 2

=> 8 : 6

Multiplying by 3

=> 4 × 3 : 3 × 3

=> 12: 9

Therefore,
