what is the height of figure 1?

subtraction addition  is commutative for rational numbers Class 8

LHS means left-hand side of the equation and RHS means right-hand side of the equation

3c(-5) = (-5)3c

The LHS of the above expression can also be written as 3 * c * (-1) * 5

The RHS of the above expression can also be written as (-1) * 5 * 3 * c

Since, this expression involved multiplication, it will definitely represent a multiplicative property. Since the order of the numbers that are being multiplied has been changed between LHS and RHS, and it is yielding the same result, it indicates that this is the commutative property of multiplication. This property states that a group of numbers can be multiplied in any order. Hence, the answer is C.

8+3.4=3.4+8

In the above, the order of the numbers being added has been changed across RHS and LHS, but is yielding the same result, it is representing the commutative property of addition. This property states that a group of numbers can be added in any order. Hence, the correct answer is C.

Answer:

Hence we can see that, when two lines are perpendicular to each other, they form 4 right angles (90 degrees).

This is the standard form equation of the circle is [tex](x - 7)^{2}[/tex] + [tex](y - 14)^{2}[/tex] = 10

The standard form equation of a circle is [tex](x - h)^{2}[/tex] + [tex](y - k)^{2}[/tex] = [tex]r^{2}[/tex], where (h, k) is the center of the circle and r is the radius.

Given the center of the circle as (7, 14) and a point on the circle as (4, 15), we can use the distance formula to find the radius:

r = [tex]\sqrt{(4 - 7)^{2} + (15 - 14)^{2} }[/tex] =  [tex]\sqrt{(-3)^{2} + (1)^{2} }[/tex]= [tex]\sqrt{9 + 1}[/tex] = [tex]\sqrt{10}[/tex]

So the standard form equation of the circle is:

[tex](x - 7)^{2}[/tex] + [tex](y - 14)^{2}[/tex] = [tex]\sqrt{(10)^{2} }[/tex]

Which can be written as:

[tex](x - 7)^{2}[/tex] + [tex](y - 14)^{2}[/tex] = 10

So the standard form equation of the circle is [tex](x - 7)^{2}[/tex] + [tex](y - 14)^{2}[/tex] = 10

I think you should provide extra information for correct answer.

that the angles etc.

A line intersects the point and is perpendicular to y=(x / 4)-2. (4,-1). y=15-4 x is the equation for this perpendicular line.

In order to determine the equation for the line perpendicular to the line [tex]$y=\frac{x}{4}-2$[/tex]passing through the point (4,-1)

The slope-intercept version of the equation for the line is [tex]$y=\frac{x}{4}-2$[/tex].

Inversely, the perpendicular line has a negative slope of m=-4.

Consequently, the perpendicular line's equation is y=-4 x+a.

Using the notion that the line should pass through the specified location, we can use the formula [tex]-1=(-4) \cdot(4)+a[/tex] to determine a.

Thus, a=15. The line's equation is therefore y=15-4 x.

Lines that cross at a straight angle (90 degrees) are said to be perpendicular. Many perpendicular lines can be seen in the actual world. Examples include the edges of a set square, a clock's arms during particular times of day, the corners of a blackboard, a window, and the Red Cross emblem.

Step-by-step explanation:

The total cost of good will equals to $33.64 after considering the 20% discount he had at the pharmacy.

A loyalty card is an identity card issued by a retailer to its customers as a form of consumer incentive scheme in which credits are accumulated for future discounts with each transaction.

Now, we will have to calculate the total cost of all the items he wants to buy after considering the 20% discount.

First, we will calculate the discounted amount:

= 20% * $42.05

= $8.41

Second, we will calculate the new amount of cost:

No, standard form does not have to be between 1 and 10. Standard form refers to a way of writing a number in which the number is expressed as a decimal between 1 and 10, multiplied by a power of 10.

Standard form, also known as scientific notation, is a way of writing a number that is a product of a decimal between 1 and 10, and a power of 10. The decimal part is called the coefficient, and the power of 10 is called the exponent.

For example, 12,000 can be written in standard form as 1.2 x 10⁴. Here, the coefficient is 1.2 (a decimal between 1 and 10) and the exponent is 4, indicating that the number is being multiplied by 10 raised to the power of 4 (10,000).

It is important to note that standard form is not limited to positive numbers and decimals between 1 and 10. A negative number or decimal less than 1 can also be written in standard form, but it would be multiplied by a power of 10 that is less than 1.

Using the indirect measurement, the height of pole is obtained to be 21 ft.

What is indirect measurement?

Using various measurements to determine the required measurement is known as indirect measurement.

Height of the fire hydrant, hf = 3ft

Height of the shadow of the fire hydrant, h'f = 4 ft

Height of the pole, hp = x

Height of the shadow of the pole, h'p = 28 ft

Both the shadows are casted at the same time, i.e. 4 pm.

So, use the method of indirect measurement -

hf/h'f = hp/h'p

3/4 = x/28

x = (3 × 28)/4

x = 84/4

x = 21

Therefore, the height of pole hp = 21 ft.

In the equation for total cost c = 1.5x + 6.99, 1.5 represents the cost of per song downloaded.

What is an equation?

A mathematical definition of an equation is a claim that two expressions are equal when they are joined by the equals sign ("=").

The equation for total cost per month is c = 1.5x + 6.99.

Where x represents the number of songs Kaj downloads and c represents the total cost, in dollars and cents.

So, c and x are variable components of the equation.

There are only two fixed components in the equation 1.5 and 6.99.

Since number of songs downloaded x is multiplied by 1.5, so 1.5 is the cost of per song downloaded.

Hence, 6.99 becomes the fixed monthly membership cost of the music service.

Answer:

no it is not a solution

Step-by-step explanation:

to determine if (- 5, 4 ) is a solution to the system, substitute the x- coordinate x = - 5 into the right side of both equations and if the value obtained is equal to the y- coordinate y = 4 then it is a solution.

Note that this must be true for both equations

y = 3(- 5) + 19 = - 15 + 19 = 4 ← True

y = - 2(- 5) - 7 = 10 - 7 = 3 ≠ 4 ← False

thus (- 5, 4 ) is not a solution to the system of equations.

Therefore , the solution of the given pentagon is the wall has a square footage of 80.7293. Asher requires four cans in total.

A polygon with five sides and five angles is called a pentagon. Penta and Gonia, two words that each denote five angles, are the components of the word "pentagon." The shape is created when the sides of such a pentagon come together at their ends.

Here,

Given that a storage shed's wall has a pentagonal shape.

A pentagon's surface can be separated into two shapes. The first shape is a rectangle, while the second is a triangle.

The rectangular shape measures 1+1+1 = 3 meters in length.

(1 + 1) = 2 metres is the width.

3 x 2 = 6 square meters make up the space of the rectangle.

Three meters make up the triangle's base.

The triangle measures 1 meter in height.

The triangle's area is 1/2 base, 1/2 height, or 1/2 x 3-1, or 3/2 square meters.

The pentagon's total area is 7.5 square meters, or 6 + 3/2 square meters.

10.7639 square feet are equal to 1 square meter.

Maria is not correct. Just because two sides of a triangle measure 8 inches, it does not mean that the triangle is isosceles.

An isosceles triangle is a triangle in which two sides are congruent, meaning they have the same length. However, just because two sides of a triangle have the same length, it does not necessarily mean that the triangle is isosceles.

There could be a third side with a different length. Therefore, it is a possibility that the third side of the triangle is not 8 inches, hence the triangle is not isosceles.

To confirm if a triangle is isosceles, we must measure all three sides and if two sides are congruent then it's an isosceles triangle.
