Which of these conditions might be true if polygons abcd and klmn are similar?

Since the angles are formed by cutting the parallel line, the value of x will be 8.Option A is correct.

It is defined as the angles when two lines intersect each other and at the intersecting point, some pair of angles are formed which we call vertically opposite angles, as the name describes that they have vertically opposite angles.

Since the angles are formed by cutting the parallel line the angle formed as,

15x-6 = 114

15x=114+6

15x=120

x=120/15

x=8

Thus. if the angles are formed by cutting the parallel line, the value of x will be 8.Option A is correct.

The required expression will be 2/x+15 as the problem says "the sum of 2 divided by x and 15".

An expression, often known as a mathematical expression, is a finite collection of symbols that are well-formed in accordance with context-dependent principles. 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. An expression in mathematics is made up of numbers, variables, and functions (such as addition, subtraction, multiplication or division etc.) You can think of expressions as being comparable to phrases. A phrase in language may contain an action on its own, but it does not constitute a complete sentence.

There are 135 complete revolutions each wheel of his bike will make.

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The track has two straight sides each of length 40m. Each end of the track is a semicircle of radius 27m. The diameter of each wheel of Ian’s bike is 590mm.

Now,

The circumference of the wheel of Lan's bike = π × 590 mm

                                                                       = 0.59 π m

And, The perimeter of the cycle track is;

⇒ 40 × 2 + 2π × 27 = 80 + 54π

So, The number of complete revolutions each wheel of his bike will make is ;

⇒ (80 + 54π) ÷ 0.59π

Answer: 134

I got this question wrong in some work, the answer is 134.

The speed represents the rate of the plane is 250 miles/ hour.

What is speed?

The distance travelled in relation to the time it took to travel that distance is how speed is defined. Since speed simply has a direction and no magnitude, it is a scalar quantity.

An object is considered to be moving at constant speed when it travels an equal distance in an equal amount of time.

When an object travels a different distance at equal intervals of time, it is said to be moving at variable speed.

Average speed is the constant speed determined by the ratio of the total distance travelled by an object to the total amount of time it took to travel that distance.

Immediately speed is When an object is travelling at a variable pace, its speed at every given moment

Speed =distance/ time taken

= 100/0.4

= 250 miles/ hour

Hence, the speed represents the rate of the plane is 250 miles/ hour.

The probability of grabbing one blue pen from the given box of 12 pens.

As given in the question,

Total number of given red pens in a box = 4

Total number of given blue pens in a box = 3

Total number of given black pens in a box = 5

Total number of pens in a given box = 4+ 3+ 5

                                                            = 12

Total number of grabbing one pen from the box = ¹²C₁

Total number of grabbing one blue pen out all the pens in the box

= ⁴C₀ × ³C₁ × ⁵C₀

Probability of selecting one blue pen from the box

= (Total number of favourable outcomes )/ ( total number of outcomes)

= (  ⁴C₀ × ³C₁ × ⁵C₀ ) / ( ¹²C₁ )

= ( 1 × 3 × 1 ) / 12

The line shows the solution of 3x−2<2x+1 by solving the inequality.

An inequality in mathematics is a comparison between two numbers or other mathematical expressions that is done in an unfair manner. On the number line, it is most typically used to compare the sizes of two numbers. With one significant exception, inequalities can be resolved in the same manner as equations by applying the same steps to both sides until the variable has been identified. If you multiply or divide by a negative number, you must flip the inequality sign.

A and b are not equal in either situation. These interactions are recognized as robust inequalities.

Given, 3x−2<2x+1

⇒3x−2x<1+2

The fourth degree polynomial in factor form is p(x) = (x - 8) · (x + 8) · (x - i 8) · (x + i 8), whose standard form is p(x) = x⁴ - 4096.

In this problem we must determine the equation of a polynomial such that it contains the roots 8, - 8, i 8 and - i 8. This can be done by using the definition of a polynomial in factor form:

p(x) = a · Π (x - rₙ), for n = {1, 2, 3, ..., m - 1, m}

Where:

And modify the expression by algebra properties until standard form is found. First, substitute the roots:

p(x) = (x - 8) · (x + 8) · (x - i 8) · (x + i 8)

Second, expand the expression by algebra properties:

p(x) = (x² - 64) · (x² - i² 64)

p(x) = (x² - 64) · (x² + 64)

p(x) = (x² - 64) · x² + (x² - 64) · 64

p(x) = x⁴ - 64 · x² + 64 · x² - 4096

p(x) = x⁴ - 4096

Answer: 4t+109.99=347.95

Step-by-step explanation:

The remaining zero of the polynomial 4x³ + 10x² - 6x - 20 is the quotient 4x² + 2x - 10 derived using synthetic division.

The polynomial p(x) = 4x³ + 10x² - 6x - 20 having a zero x = -2 implies that x + 2 is a factor and has another factor derived by dividing p(x) = 4x³ + 10x² - 6x - 20 by x + 2.

we shall derive the other factor using the synthetic division as follows;

divide the first term 4x³ of the polynomial by x (of x + 2) to give 4x²,

multiply x + 2 by 4x² to give 4x³ + 8x²

then subtract 4x³ + 8x² from 4x³ + 10x² - 6x - 20 to give 2x² - 6x - 20

divide 2x² (of 2x² - 6x - 20) by x (of x + 2) to give 2x

multiply x + 2 by 2x to give 2x² + 4x

then subtract 2x² + 4x from 2x² - 6x - 20 to give -10x - 20

divide 10x (of -10x - 20) by x (of x + 2) to give -10

multiply x + 2 by -10 to give -10x - 20

then subtract -10x - 20 from -10x - 20 to give a remainder of zero.

Hence, the results 4x², 2x, and -10 are the terms of the quotient 4x² + 2x - 10 and forms the remaining zeros of the polynomial p(x) = 4x³ + 10x² - 6x - 20.

Answer:

The answer is 45

Step-by-step explanation:

the way to find this answer is by, first, knowing that each angle of a triangle adds up to 180. So, we must first add the 85 and 50 which will give us 135. After, you subtract it all from 180, which gives you 45.

In the triangle, the value of x is,

⇒ x = 45°

We have to given that;

In triangle;

The angles are 85 degree, 50 degree and x.

Since, We know that;

Sum of all interior angle of a triangle are 180 degree.

Hence, We get;

⇒ x + 85 + 50 = 180

⇒ x + 135 = 180

⇒ x = 180 - 135

⇒ x = 45°

Thus, the value of x is,

⇒ x = 45°

The slope that needs to be programmed into the computer to accomplish the delivery is x=3441/100.

A fundamental relationship in Euclidean geometry between a right triangle's three sides is known as the Pythagorean theorem or Pythagoras theorem in mathematics. It is believed that the area of the square with the hypotenuse equals the sum of the areas of the squares on the other two sides.

Pythagoras, a Greek philosopher who was born around 570 BC, is honored in the name of the theorem. Perhaps more than any other mathematical theorem, the theorem has been demonstrated several times using a variety of techniques. There are many different types of proofs, some of which go back thousands of years, including both geometric proofs and algebraic proofs.

By using Pythagorean theorem,

x²=20²+28²

x²=400+784

x²=1184

x=34.41

x=3441/100

Answer: unit of account

Step-by-step explanation:

I learned this in Macro Chapter 34.

An apple would cost $0.6 while a plum would cost $0.25.

The total cost of buying 2 plums and 2 apples will be $1.7

Cost is the value of money that has been used or exchanged up to produce something or deliver a service. Money is an input that is gone in order to acquire something.

If 6 plums sell for $1.50, then;

1 plum will be (1.50/6) = $0.25

Also, if 5 apples cost $3.00, then;

1 apple will be (3/5) = $0.6

Therefore 2 apples will cost: 2 x $0.6 = $1.2

and 2 plums will cost: 2 x $0.25 = $0.5

Total cost for 2 apples and 2 plums will be = $1.2 + $0.5
