The value of the variable expression 6.(x- 9) - 5 when x = 5 is -29.

To evaluate the variable expression for x = 5, we simply substitute 5 for x in the expression.

6.(x- 9) - 5 = 6.(5- 9) - 5

= 6.(-4) - 5

= -24 - 5

= -29

Therefore, the value of the variable expression 6.(x- 9) - 5 when x = 5 is -29.

Answer: The value of the investment would be $4,075

Step-by-step explanation: The initial investment, that is, the principal is given as $2500, and it was invested for a period of 10 years at the rate of 6.3%. Using the simple interest calculation formula, the investment would have a present value as follows;

Interest = P x R x T

Where P = amount invested (2500), R = rate of interest (6.3 or 0.063) and T = number of years (10)

Interest = 2500 x 0.063 x 10

Interest = 1575

The value of the investment at 6.3% after 10 years is now;

Initial investment + Interest

2500 + 1575 = 4075

Therefore the value of the investment is $4,075

Step-by-step explanation:

The area of the composite figure to the nearest whole number is 13 ft².

Area is the entire amount of space occupied by a flat (2-D) surface or an object's shape. The area of a plane figure is the area that its perimeter encloses. The quantity of unit squares that cover a closed figure's surface is its area.

Given:

Radius= 2 feet

As, Area of a single Quadrant = πr²/4

and, For 3 semi circle

= πr²/4 + πr²/4 + πr²/4 or 3 (πr²/4)

= 3 x 3.14 x 2 x 2 /4

= 9.42 ft²

and, Area of Square

= s x s

= 2 x 2

= 4 ft²

So, the Area of Figure = 4 + 9.42 = 13.42 ft²

Step-by-step explanation:

Answer:

[tex]\dfrac{\pi}{2} cm[/tex]

Step-by-step explanation:

Given two concentric circles where:

Length of the intercepted arc for a central angle of [tex]\dfrac{\pi}{2} =\dfrac{\frac{\pi}{2} }{2\pi} X2\pi r=\dfrac{\pi r}{2}[/tex]

For the larger circle of radius 5cm, Length of the intercepted arc[tex]=\dfrac{5\pi}{2}[/tex]

For the smaller circle of radius 4cm, Length of the intercepted arc[tex]=\dfrac{4\pi}{2}[/tex]

Difference in Arc length

[tex]=\dfrac{5\pi}{2}-\dfrac{4\pi}{2}\\=\dfrac{\pi}{2} cm[/tex]

The difference in arc lengths between the two concentric circles for a central angle of π/2 radians is approximately 1.57 cm.

To compare the lengths of arcs intercepted by the same central angle in two concentric circles, we use the formula for arc length, which in a circle is a portion of its circumference that corresponds to the central angle. For a central angle π/2 radians, the arc length is given by (rθ), where r is the radius of the circle and θ is the central angle in radians.

For the smaller circle, the arc length is 4 cm × π/2 = 2π cm, and for the larger circle, it is 5 cm × π/2 = 2.5π cm. The difference in arc lengths is 2.5π cm - 2π cm = 0.5π cm. Using the approximate value of π as 3.14159, the difference in arc lengths is approximately 1.57 cm.

Answer:

Median

Step-by-step explanation:

Remember ...

Mean = Average

Median = Middle

Mode = Most (the number that appears most)

Final answer:

The midpoint value of a data set arranged in order is the median, which is the central value dividing the dataset into two halves.

Explanation:

The midpoint value of a data set, where the values are arranged in ascending or descending order, is known as the median. The median is the value that divides the dataset in half so that there are an equal number of values above and below it. In a dataset with an odd number of data points, the median is the middle value. For an even number of data points, the median is the average of the two central values. The mode is the most frequently occurring value in a set, while an outlier is an observation that is significantly different from the rest of the data. The mean represents the average of all values in the data set.

Choosing the appropriate measure of the center of data — whether mean, median, or mode — depends on the specific characteristics of the dataset, such as the presence of outliers and the distribution shape. The median is especially useful when the dataset contains outliers that may skew the mean.

Answer:

36 miles

Step-by-step explanation:

His entire journey, represented with a diagram, is in the shape of a right angle triangle.

We need to first find the hypotenuse of the triangle, then, add all the sides together:

hyp² = opp² + adj²

hyp² = 9² + 12²

hyp² = 81 + 144 = 225

Find the square root of both sides:

hyp = 15 miles

Therefore, adding the three sides together:

Total distance traveled = 9 + 12 + 15

Total distance traveled = 36 miles

He would ride 36 miles altogether.

Area of the shaded region =[ (3x-2)(x+3) ] - [ x*6 ]

= 3x*x +3x*3 + (-2)*x  + (-2)*3 - 6x

=3x² + 9x - 2x - 6 - 6x      {bring like term together}

=3x² + 9x - 2x - 6x - 6

= 3x² + x - 6           {9x - 2x - 6x = 9x - 8x = x}

Area = 24 square units

3x² + x - 6 = 24

3x² + x - 6 - 24 = 0

3x² + x - 30 = 0

Product = 3* -30 = -90

Sum = 1

Factors = 10 , (-1)

3x² + x - 30 = 0

3x² - 9x + 10x - 10*3 = 0

3x*(x - 3) +10*(x - 3) = 0

(x-3)(3x +10) = 0

3x + 10 is ignored because measurements will not be in negative values.

Final answer:

The area of a larger square with side lengths twice that of a smaller square is four times greater. This is because the scale factor for areas is the square of the scale factor for lengths, leading to an area of 64 square inches for the larger square, compared to 16 square inches for the smaller one.

Explanation:

When Marta has a square with a side length of 4 inches and then creates a similar square with dimensions that are twice the first square, we are working with a scale factor in geometry. As the new square has side lengths that are twice that of the original square (4 inches x 2 = 8 inches), the area of the larger square will be greater than that of the smaller square. To find the area of the larger square, we square the side length (8 inches x 8 inches), which gives us 64 square inches. This is exactly four times the area of the first square (4 inches x 4 inches = 16 square inches), since the scale factor for the areas of similar figures is the square of the scale factor for their corresponding lengths.

In the context of the examples given, this principle applies to understanding how the area of shapes scales when their dimensions are proportionally increased or decreased. The scale factor can be used to calculate dimensions or area of similar figures in various geometric problems.

Answer: The number of quarters can be 1, 3, 5 or 7

Step-by-step explanation:

Megan has A quarters and B dimes.

The value of a quarter is $0.25 and the value of a dime is $0.10

Then we have that:

A*$0.25 + B*$0.10 = $1.95

We want to know the different possible values of A.

Now, it is usefull to see the different multilpes of 0.25 (this is the odd multyples of 0.25) we only care for the ones that have a 5 in the undredth place, becauses we only can ad multiple of $0.10, so the 5 in the undredth place needs to come from this

Then the possible values of A are the odd numbers such that A*0.25 is smaller than 1.95, let's do the math:

0.25*1 = 0.25 (here 1.95 - 0.25 = 1.70, then B = 1.70/0.10 = 17) the pair is B = 17 and A = 1

0.25*3 = 0.75 (here 1.95 - 75 = 1.20, then B = 1.20/0.10 = 12) the pair is B = 12 and A = 3.

0.25*5 = 1.25 (here 1.95 - 1.25 = 0.70, then B = 0.70/0.10 = 7) the pair is B = 7 and A = 5

0.25*7 = 1.75 (here 1.95 - 1.75 = 0.20, then b = 0.20/0.10 = 2) The pair is B = 2 and A = 7

[tex]d=3804.8 in[/tex]

Divide by 12 to find the feet

[tex]3804.8[/tex]÷[tex]12=d[/tex]

[tex]d=317.066[/tex]

Round to the nearest foot

[tex]d=317[/tex]

Final answer:

To find the actual stadium distance from home plate to left field, convert 16.4 inches to feet and then multiply by the scale factor of 232, resulting in approximately 317 feet.

Explanation:

The student is asking how to convert a scale model measurement to the actual size measurement. Given the scale of 1:232 and the model's distance from home plate to left field as 16.4 inches, we can find the actual stadium distance by multiplying the model measurement by the scale factor.

First, convert inches to feet: 16.4 inches × (1 foot / 12 inches) = 1.3666667 feet (rounded to seven decimal places).

Then multiply by the scale factor to get the distance in the actual stadium: 1.3666667 feet × 232 = 317.0666674 feet, which we round to 317 feet to the nearest foot.

Therefore, the distance from home plate to left field in the actual stadium is approximately 317 feet.
