For the given triangles ΔABC ≈ ΔXYZ, the length of the side AB is, 24

Triangles with the same shape but different sizes are said to be similar triangles. Squares with any side length and all equilateral triangles are examples of related objects. In other words, if two triangles are similar, their corresponding sides are proportionately equal and their corresponding angles are congruent. Triangle resemblance is shown here by the symbol "≈"

Given that,

One triangle, ΔABC

Another triangle , which is ΔXYZ

Triangle ΔABC and ΔXYZ similar,

So, we can say ΔABC ≈ ΔXYZ

And it is known that

for similar triangles, ratio of lengths of sides are equal for similar triangles

so, AB/BC = XY/ZY

⇒   X/18   =  16/12

⇒   X   =  24

Hence, the value of x is 24

The value of y'(2) is 135/16.

The correct option is A.

Mathematicians use a procedure called differentiation to determine a function's instantaneous rate of change based on one of its variables.

Given:

y = (x - 1/x)³

Differentiating the function with respect to x,

y' = 3x² +3/x⁴ - 3 - 3/x²

y'(2) = 12 + 3/16 - 3 -3/4

y'(2) = 135/16

What is the temperature?

Temperature is a physical property of matter that measures the degree of hotness or coldness of an object. It is a scalar quantity that is expressed in units such as Celsius, Fahrenheit, or Kelvin.

The statement "f(4) < f(5)" means that the outside temperature 4 hours after 3 A.M. is less than the temperature 5 hours after 3 A.M. In other words, the temperature is rising over time and the value of f(t) increases as t increases.

Applying the angle bisector theorem, the lengths are:

A. KL = 2.4, LW = 3.6

The Angle Bisector Theorem states that in a triangle, the ratio of the length of a side to the length of another side is equal to the ratio of the length of the angle bisector of one of the angles to the angle bisector of the corresponding angle.

In other words, if two angles of a triangle have angle bisectors of lengths x and y, then x/y = a/b where a and b are the lengths of the sides of the triangle corresponding to the bisected angles.

Based on the angle bisector theorem, we have:

(6 - x)/(x) = 4/6

Cross multiply:

4x = 6(6 - x)

4x = 36 - 6x

4x + 6x = 36

10x = 36

x = 36/10

x = 3.6

LW = x = 3.6

The money left from last month's earnings is $1660.35.

Subtraction can be done for any numbers or algebraic expressions. It is the process of taking out certain value from a given amount of number.

The process of subtraction can also be termed as finding difference.

In order to find the money left, we have to find the difference of earnings and expense.

Earnings = $4,283.30

Expense for bills = $4,283.30 × (3/5) = $2569.98

Expense for shirts = $19.99 × 2 = $39.98

Expense for sunglasses = $12.99

Total expense = $2569.98 + $39.98 + $12.99 = $2622.95

Money left = $4,283.30 - $2622.95 = $1660.35

If a large equilateral triangle pyramid stands in front of the city's cultural center. The time  it take the painter to paint 75% of the pyramid is 10.8 hours.

The area of the base is:

(1/2) * 40 * 40

= 800 square feet

The area of one lateral face is:

(1/2) * 50 * 40

= 1000 square feet

So, the total area of all four lateral faces is:

4 * 1000

= 4000 square feet

The total surface area of the pyramid is:

800 + 4000 = 4800 square feet

To paint 75% of the pyramid, the painter needs to paint:

0.75 * 4800

= 3600 square feet

Time it will take them is:

3600 / 100 * 18

Peeta worked 9.41 hours on Sunday. The equation 5.5h + 90.2 = 142.2 can be used to determine the number of hours Peeta worked given his earnings.

The equation model is defined as the model of the given situation in the form of an equation using variables and constants.

Let h be the number of hours that Peeta worked on Sunday. We know that he earned $5.50 per hour and $90.20 in tips. So, his total earnings can be represented as:

5.5h + 90.2 = 142.2

Solving for h:

5.5h = 142.2 - 90.2
5.5h = 52

a. Perimeter = 72 yd

b. Area = 640 yd².

a. To find the perimeter of the compound figure, we need to add the lengths of all four sides together.

The perimeter is equal to 16 yd + 32 yd + 16 yd + 8 yd = 72 yd.

b. To find the area of the compound figure, we need to separate the figure into two separate shapes and find the area of each.

The figure can be separated into a 16 yd by 32 yd rectangle and a 8 yd by 16 yd rectangle.

The area of the 16 yd by 32 yd rectangle is 16 yd x 32 yd = 512 yd² and the area of the 8 yd by 16 yd rectangle is 8 yd x 16 yd = 128 yd². The total area is 512 yd² + 128 yd² = 640 yd².

The lateral surface area of the pyramid is 200 square inches.

A three-dimensional figure is a pyramid. Its base is a flat polygon. The remaining faces are all triangles and are referred to as lateral faces. The number of sides on its base is equal to the number of lateral faces. The line segments that two faces intersect to form its edges. The intersection of three or more edges forms a vertex.

We know the lateral surface area of a pyramid is = (1/2)×P×h, where P is the perimeter of the base.

Given, Each side of the base of a square pyramid measures 10 inches.

So, The perimeter of the pyramid is 4×10 = 40 inches.
