Jacob walks 2/5 kilometres in 1/4 hour. what is jacobs speed in kilometres per hour?

A linear equation is an equation in which the highest power of the variable is 1 and a nonlinear equation is an equation in which the highest power of the variable is greater than 1.

A linear equation example:

y = 2x + 3

This is a linear equation in one variable, x. The highest power of x is 1 and the coefficient of x is 2.

A nonlinear equation example:

y = x^2 + 3x + 2

This is a nonlinear equation in one variable, x. The highest power of x is 2 and the coefficient of x is 1.

Another example of nonlinear equation is:

y = x^3+3x^2-5x+1

This is a nonlinear equation in one variable, x. The highest power of x is 3 and the coefficient of x is 1.

Note that the linear equation can be in any number of variables, and the nonlinear equation can also be in any number of variables, but the degree of the polynomial should be greater than 1.

Answer: The scale factor of triangle CAT to triangle MUD is the ratio of the corresponding side lengths of the two triangles. In this case, we are told that the sides of triangle CAT are 9, 18, and 21 units long, and the sides of triangle MUD are 3, 6, and 7 units long.

To find the scale factor, we divide the length of each side of triangle CAT by the length of the corresponding side of triangle MUD:

Scale factor = (9/3), (18/6), (21/7) =3,3,3

So the scale factor of triangle CAT to triangle MUD is 3. This means that triangle CAT is 3 times larger than triangle MUD.

It's worth noting that the scale factor is the same for all three sides, this means that the two triangles are similar.

Step-by-step explanation:

The value of √N is 3.16159

Pythagorean theorem, the well-known geometric theorem that the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse (the side opposite the right angle)—or, in familiar algebraic notation, a² + b² = c².

Given here: A quadrilateral WXYZ with ∠Z=75 and ∠X=105

Let P be a point on ZW such that ZP=x and WP=4-x, then we form a right-angled triangle ΔZPY with tan 15°=x/PY

∴ PY=x/tan 15

       =3.732x

Now using Pythagoras' theorem we get ZY as

 [tex]\sqrt{13.927x^2+x^2} \\=\sqrt{14.92x^2}\\ =3.862641x[/tex]

Now let's connect the diagonal ZX we get the right triangle ZWX

Thus using Pythagoras' theorem we get

ZX=[tex]\sqrt{4^2+4^2}[/tex]

    =4√2

Again let Q be an extension such that YQ=4-x & ∠YXQ=75°

Thus Sin 75=4-x/√N

            √N=4-x/0.965923

squaring both sides we get N=(4-x)²/0.9330127........(1

Now using the Pythagoras theorem in ΔZYX we get

√N=

[tex]\sqrt{ZX^2-ZY^2} \\=\sqrt{32-14.92x^2} \\[/tex]

⇒N=32-14.92x²..,.......2)

Thus equation two values of N we get

(4-x)²/0.9330127=32-14.92x²

16-8x+x²=29.8564-13.920549x²

14.921x²-8x-13.856=0

Thus using the quadratic formula we get the value of x as

x= 8±29.85 /29.84

x=1.2684  (∵ Distance cannot be negative)

∴ Value of N=32-14.92×1.2684

                    N=13.075

                   √N=3.6159

Hence, The value of √N is 3.16159

All 3 angles of a triangle always add up to 180 degrees.

This is because a triangle is a three-sided polygon and the sum of the angles in any polygon is always 180 degrees multiplied by the number of sides minus 2. Therefore, in a triangle, which has three sides, the sum of the angles is 180 x (3-2) = 180 degrees. This rule is known as the "triangle angle sum theorem" and is a fundamental property of triangles. It is important to note that this rule applies to all types of triangles, whether they are right triangles, acute triangles, or obtuse triangles. Understanding this theorem is crucial in solving geometric problems related to triangles.

Answer:

B. 66 degree

Step-by-step explanation:

We know

A triangle is 180 degrees. Angle B is 27 degrees, and angle C is 87 degrees. To find angle A, we take

27 + 87 = 114 degree

180 - 114 = 66 degree

So, the answer is B. 66 degree

Yes, the distributive law is followed by the addition arithmetic operation. 

Distributive Property of Multiplication Over Addition: This implies that the operation involves dividing or distributing the things. The distributive law applies to addition and subtraction arithmetic operation.

For example, let us multiply 8 by the sum of (20 + 3). Mathematically, we can represent this as 8 (20 + 3). First, use the distributive property to multiply each addend by 8. This is called distributing the number 8 over two addenda and then adding their products. That is, multiplication of 8(20) and 8(3) will be performed first, then addition. The result is 8 (20) + 8 (3) = 160 + 24 = 184.

How do you identify inequalities?

The equals sign in the equation-like statement 5x 4 > 2x + 3 has been replaced by an arrowhead. This is a prime instance of inequality. This indicates that the left half, 5x 4, is larger than the right part, 2x + 3, in the equation.

The correct way to write greater than 35 is A > 35 where it tells that A having greater value than 35.

In mathematics,

→The greater than symbol (>) is used to indicate that one value is larger than another. For example, if we say "A > B," this means that the value of A is greater than the value of B.

→The less than symbol (<) is the opposite, it indicates that one value is smaller than another. For example, if we say "A < B," this means that the value of A is less than the value of B.

→The greater than or equal to symbol (≥) indicate that one value is larger than or equal to another. For example, if we say "A ≥ B," this means that the value of A is greater than or equal to the value of B.

→The less than or equal to symbol (≤) indicate that one value is smaller than or equal to another. For example, if we say "A ≤ B," this means that the value of A is less than or equal to the value of B.

These symbols are commonly used in mathematical expressions, equations, and inequalities.

To write "greater than 35" in mathematical notation, you would use the greater than symbol (>) followed by the letter 35. For example:

A > 35

This means that A is greater than 35.

|y - 8| + 11 - 11 > 19 - 11

|y - 8| > 8

Now we can decompose that into two inequalities so we get:

y - 8 > 8

y - 8 < -8

To solve the equation m/3-7 =1, we can start by isolating m on one side of the equation. To do this, we will add 7 to both sides of the equation:

m/3 - 7 + 7 = 1 + 7

m/3 = 8

The next step is to multiply both sides of the equation by 3 to get rid of the fraction:

m/3 * 3 = 8*3

In an additive comparison, we question or state how much more (or less) one amount is in contrast to the other to determine the relationship between the two numbers. Additive comparison issues are typically word problems that can be resolved by creating an equation.

The comparison approach is a technique for rewriting each equation with the same variable as the subject in order to solve systems of independent equations. The initial variable to isolate can be any of the variables. Every equation is now an isolated-subject equation with an isolated variable.

Let,

  if in about x month, the population of the towns will be equal .

the equation will be;

Answer:r=175 this is for IXL I hope this helps

Step-by-step explanation:

r/-25 =-7

Multiply both sides of the equation by -25

-25 times r/-25=-25 time (-7)

Multiplying two negatives equals a positive: (-) times (-) =(+)

25•r/25=-25•(-7)

The factors of polynomial a² - 2ab + b² is equals to the (a - b)², that is (a -b) and (a-b).

To determine the factors we can use the concept of splitting the middle terms and first making the pair of two terms and then finding the common factors from the paired terms and finally the factors for the expression. We have an expression, a² - 2ab + b². Using the concept of to split the middle term. As we see there is three terms in the expression.

Thus, we can rewrite the expression as

=> a² - ab - ab + b²

Make the pair of two terms in the above expression, (a² - ab) - ( ab - b²).

Take common factors from the paired terms,

=> a(a - b) - b(a - b).

Take the common factors in the above equation => (a - b) (a - b)

=> (a - b)¹⁺¹ = (a + b)²

Hence, factor of a² - 2ab + b² is (a-b)² i.e., (a - b) and (a - b).
