Each circle represents a number. The left side of the equation (4(x+5)) can be divided by 4 to find the value of x+5. The value of x is 4.70

The distance between a circle's center and periphery is referred as the radius. Always, the diameter is twice the radius. As a conclusion, the diameter is multiplied by two to obtain the formula.

The ratio of a circle's circumference to diameter serves as the basis for the traditional definition of Pi (). The diameter or length of such a circle is its circumference. A straight line connecting a point on one end of both the ring to a place on the opposite end, through the center, is the diameter.

Diameter = 2r -----------(1)

where r is the radius

The value of the diameter = 32 m   and  radius is given to be 4(x+5)

substitute the above into equation (1)   and then solve for x

32  =  2 [ 4(x + 5)]

first open the inner bracket

32 = 5[4x + 20}

then open the outer bracket

32 = 20x + 100

subtract 16 from both-side of the equation

20x=100-32

20x=68

x=3.4

Divide both-side of the equation by 3.4

16/3.4  = 8x/3.4

4.70 = x

x = 4.70

Therefore, the value of x is 4.70

Currently, Michael is 72 years old

Let's represent Michael's current age as "x".

Then Brandon's current age is x/3.

18 years ago, Michael's age was x-18

Brandon's age was x/3-18.

18 years ago, we can write the equation:

x - 18 = 9 * (x/3 - 18)

So, we have

x - 18 = 3x - 162

Evaluate the like terms

2x = 144

Divide by 2

x = 72

So, Michael is 72 years old now.

Answer:

w = 25

Step-by-step explanation:

8/5w = 40

Divided both sides by 8/5

w = 25

Let's check

8/5(25) = 40

40 = 40

So, w = 25 is the correct answer.

Answer: w = 25

Step-by-step explanation:

    To solve for w, we will isolate the variable by using inverse operations.

    Given:

[tex]\displaystyle \frac{8}{5} w=40[/tex]

    Divide both sides of the equation by [tex]\frac{8}{5}[/tex]:

* Note: w is being multiplied by [tex]\frac{8}{5}[/tex], so the inverse operation is division

[tex]\displaystyle w=\frac{40}{\frac{8}{5 } } \mapsto w=40*\frac{5}{8} \mapsto w=*\frac{40*5}{8} \mapsto\frac{200}{8} \mapsto \boxed{w=25}[/tex]

The value of the segment FE for the similar triangles is equal to 6.

The triangles EFG and ECD are similar, this implies that the length FE of the smaller triangle is similar to the length CE of the larger triangle

and the length FG of the smaller triangle is similar to the length CD of the larger triangle

so;

FE/12= 6/2FE

2(FE)² = 12 × 6 {cross multiplication}

2(FE)² = 72

(FE)² = 72/2

(FE)² = 36

FE = √36 {take square root of both sides}

FE = 6.

Therefore, the value of the segment FE for the similar triangles is equal to 6.

In light of the query we've got D)x + y ≤ -2 and 2x - 3y ≤ -9 is a pair of inequalities for (-3, 1) is the correct answer.

When resolving an inequality, you can do one of the following: · Add a same number to each side; • Subtract the same amount from each side; • Multiply or divide either aspect by the exact positive amount. You must flip the inequality sign if you combine or split each end by a negative number.

According to the values x = -3, y = 1

-3 + 1 = -2, which is less than or equal to -2, so the first inequality is true.

2 * -3 - 3 * 1 = -9, which is less than or equal to -9, so the second inequality is also true.

Since both inequalities are true, (-3, 1) is a solution for the system of inequalities x + y ≤ -2 and 2x - 3y ≤ -9.

The number of cubes fitted in the storage box is 448.

The space occupied within an object's borders in three dimensions is referred to as its volume. It is sometimes referred to as the object's capacity.

Given:

Edge length of cube = 1/2 inch

So, volume of a cube = (Side)³

                                    = (1/2)³

                                    = (1/8)

Now, Volume of the storage box = 56 cubic inches.

So, number of cubes fitted in the storage box

= Volume of the storage box / volume of a cube

= 56/ (1/8)

= 56 x8

= 448 cubes

Hence, number of cubes fitted is 448.

Triangle ABC with a hypotenuse of 7 units and angle B equal to 70 degrees,

Since triangle ABC is a right triangle and angle B is 70 degrees, it can be deduced that angle C must be 90 - 70 = 20 degrees.

assuming

length of side AC  = a

length of side BC = b.

Using the Pythagorean theorem, we can find the values of a and b.

a^2 + b^2 = 7^2

a^2 = 7^2 - b^2

a = √(7^2 - b^2)

Using the tangent function

tan C = b/a

tan 20 = b/√(7^2 - b^2)

Solving for b, we get:

b = tan(20) * √(7^2 - b^2)

We can use numerical methods to find the approximate value of b. Using a calculator, we can find that b is approximately 4.7. Rounding to the nearest tenth, b is 4.7 units.

Finally, using the Pythagorean theorem again, we can find the value of a:

a^2 + b^2 = 7^2

a^2 = 7^2 - b^2 = 7^2 - 4.7^2

a = √(7^2 - 4.7^2)

a = √(7^2 - 22.09)

Using a calculator, we can find that a is approximately 5.3. Rounding to the nearest tenth, a is 5.3 units.

The numerical value of the standard deviation is never (B) less than the variance and is never negative.

The standard deviation is a statistic that expresses how much variance or dispersion there is in a group of numbers.

While a high standard deviation suggests that the values are dispersed over a wider range, a low standard deviation suggests that the values tend to be close to the mean (also known as the anticipated value) of the collection.

The standard deviation's numerical value is always greater than the variance and can never be negative.

The lowercase Greek letter (sigma), for the population standard deviation, or the Latin symbol s, for the sample standard deviation, are most frequently used in mathematical texts and equations to indicate standard deviation.

Standard deviation may be written as SD.

Step-by-step explanation:

Answer: The mean absolute deviation for the given data set is 19.

Step-by-step explanation:

The mean absolute deviation (MAD) is a measure of the variability of a set of data and is defined as the average of the absolute deviations of each data point from the mean. To find the MAD, we first need to find the mean of the data set, and then subtract each data point from the mean and take the absolute value of the result.

Here is the step-by-step process for finding the MAD for the given data set:

Find the mean of the data set: (108 + 53 + 47 + 22 + 56 + 62) / 6 = 56

Subtract the mean from each data point:

108 - 56 = 52

53 - 56 = -3

47 - 56 = -9

22 - 56 = -34

56 - 56 = 0

62 - 56 = 6

Take the absolute value of each result:

|52| = 52

|-3| = 3

|-9| = 9

|-34| = 34

|0| = 0

|6| = 6

Find the average of the absolute deviations: (52 + 3 + 9 + 34 + 0 + 6) / 6 = 19

So the mean absolute deviation for the given data set is 19.

The trapezoidal rule is a numerical integration method that frequently overestimates the real value of a function's definite integral.

The trapezoidal rule is a strategy for approximating the definite integral in calculus. The trapezoidal rule works by computing the area of the region under the graph of the function f(x) that is approximated as a trapezoid. The trapezoidal rule is commonly used to calculate the area under curves. This is achievable if the overall area is divided into smaller trapezoids rather than rectangles. The Trapezoidal Rule integration determines the area by approximating the area under a function's graph as a trapezoid. The midway rule uses rectangular areas to approximate the definite integral, whereas the trapezoidal rule uses trapezoidal approximations to approximate the definite integral. Simpson's approach works by first approximating the original function with piecewise quadratic functions.
