The value of the missing length is 44.

Two or more triangles will be similar if on comparing their corresponding sides or measure of angles, some common properties can be observed. But when two or more shapes are similar, it do not imply that they are equal.

To find the value of the missing length, let the length LV be represented by s.

So that;

VN/ LN = NU/ MN

11/ (11 + s) = 8/ (24 + 8)

11/ (11 + s) = 8/ 32

cross multiply to have;

8(11 + s) = 11 *32

88 + 8s = 352

8s = 352 - 88

    = 264

s = 264/8

  = 33

Therefore, the missing length = 11 + 33

                        = 44

The depth of snow in the yard one hour after the snow depth was 9 inches, obtained using the linear function used for finding the snow depth, D = 1.4·t + 3 is; 10.4

A linear function is a function that produces a straight line graph when plotted.

The function that can be used to calculate the depth of the snow D in inches is; D = 1.4·t + 3

Where;

D = The snow depth in inches

t = The time duration (hours)

The present depth of the snow = 9 inches

The depth of the snow one hour from now can be found as follows;

The function for the depth of the snow; D = 1.4·t + 3 is a linear function

Therefore, the slope, which is the coefficient of the input variable, t, when the coefficient of the output variable, D, is 1

Therefore, the slope = 1.4

The slope is the rate of change of the output variable D when the input variable increases by one unit

The slope therefore, indicates that the depth of the snow in the yard, increases by 1,4 inches per hour

If the depth of the snow is presently 9 inches, the depth of the snow 1 hour later is therefore; D = 9 inches + 1.4 inches = 10.4 inches

The three integers are 89,406, 89408 and 89410.

What are integers?

The Latin term "Integer," which implies entire or intact, is where the word "integer" first appeared. Zero, positive numbers, and negative numbers make up the particular set of numbers known as integers.

Let 'm' be a positive integer.

Then, 2m is an even integer ( as multiplying by 2 makes the number even)

So, 2m+2 is the next integer and 2m+4 is the next.

Now, we have three consecutive integers as 2m, 2m+2 and 2m+4.

We are given that twice the first integer added to the second is 2,68,220, this means

⇒2(2m) + (2m+2) = 2,68,220

⇒4m + 2m + 2 = 2,68,220

⇒6m + 2 = 2,68,220

⇒6m = 2,68,218

⇒m = 44,703

So, 2m = 89,406

2m+2 = 89408

2m+4 = 89410

Hence, the three integers are 89,406, 89408 and 89410.

The sentence into a mathematical equation is R = 160x

The sentence "The difference between a number and ten is four" can be translated into a mathematical equation as:

To solve for x, we can add 10 to both sides of the equation. This will give us:

x - 10 + 10 = 4 + 10

x = 14

Therefore, the number is 14.

More generally speaking, we can say that the equation for this sentence is x - a = b, where a is the number we are subtracting (in this case 10) and b is the result of the subtraction (in this case 4). To solve for x, we add a to both sides of the equation, giving us x = a + b.

An absolute maximum point is where the function reaches its highest value.

A function may have more than one location (x values) or point (ordered pairs) where these values occur, but there can be only one absolute minimum value and one absolute maximum value (in a given closed interval).

A point where the function achieves its highest value is known as an absolute maximum point. Similar to this, an absolute minimum point is the location at which the function's maximum value is obtained.

Minimum refers to the bare minimum that can be done. For instance, if anything requires seven dollars as the minimum payment, you cannot make a payment of six or less (you must pay at least seven). More than the bare minimum is acceptable, but not less. Maximum refers to the greatest quantity of anything.

The fixed point of the function f(x) = x^2 + 1 is c = 0.

f(x) = x^2 + 1

c = 0

To find the fixed point of the function f, we can set the equation f(x) = x^2 + 1 equal to x, since the fixed point is when f(x) is equal to x.

Therefore, we can solve for x by setting x^2 + 1 = x. Re-arranging the equation, we get x^2 - x + 1 = 0.

Using the quadratic formula, x = (-(-1) ± √(1 - 4(1)(1))/(2(1))

Simplifying this expression, x = (-1 ± √3)/2.

Since we are looking for a real number, we can eliminate the negative solution and set x = (1 + √3)/2.

Therefore, the fixed point of the function f is c = 0.

The quantity of chlorine that has a 60% concentration is 310 ml.

Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement. It's possible to multiply, divide, add, or subtract with this mathematical operation.

Given that,  60% chlorine solution must be mixed with an 18% chlorine solution to produce 542.5 mL of 42% solution

Let "x" be the quantity of chlorine that has a 60% concentration

So, the quantity of chlorine that has 18% concentration = 542.5 - x

thus, As per the given data expression formed as given below:

0.6 * x + 0.18 (542.5 - x) = 542.5 * 0.42

0.6x - 0.18x + 0.18 *542.5 = 542.5 *0.42
