Answer:

m = 55

Step-by-step explanation:

Choose 2 ordered pairs on the number line; i chose (0,125) and (2,235)

The formula for slope (m) is m = y2 - y1 / x2 - x1

In this problem, it would be:

m = 235 - 125 / 2 - 0

m = 110/2

m = 55

Answer:

76.5 cm²

Step-by-step explanation:

Given the triangles are similar , then

ratio of sides = a : b , so

ratio of areas = a² : b²

Here ratio of sides = 9 : 13.5 = 2 : 3

ratio of areas = 2² : 3² = 4 : 9

let x be the area of Δ DEF and using proportion

[tex]\frac{4}{34}[/tex] = [tex]\frac{9}{x}[/tex] ( cross- multiply )

4x = 306 ( divide both sides by 4 )

x = 76.5

The area of Δ DEF = 76.5 cm²

Answer:

yes I think 6 is a solution to the equation

Can't see the equation sorry... Don't think you can change your question you typed either

Answer and Step-by-step explanation:

We have to solve for d.

First, we can divide each value by 5 (due to each value being divisible by 5).

d + 10 = 80

Subtract 10 from both sides of the equation.

d = 70     <-- This is your answer.

Answer:

the value of x=10°

Step-by-step explanation:

hey there!

as there is given angles of the triangle i.e. 5x,9x,4x

now adding all of them,

5x +4x+9x=180 (reason: sum of angle of a triangle is 180°)

18x=180

x=180/18

x=10

therefore the value of x is 10

now the value of each angle is;

5x= 5*10=50

4x=4*10=40

9x=9*10=90

hope it helps! thank u!!!

The equation that shows the relationship between the number of seconds since the boy let the balloon go is y = 3x + 3.

A function can be defined as the outputs for a given set of inputs.

The inputs of a function are known as the independent variable and the outputs of a function are known as the dependent variable.

Given, A little boy accidentally let go of his balloon, and it floated away. It was 3 feet above the ground when he let go this height is our constant value in the function.

It steadily rose 3 feet per second.

Assuming time in seconds to be x and total height is y.

∴  An equation that shows the relationship between the number of seconds since the boy let the balloon go is,

y = 3x + 3.

Integers are numbers without decimals

The integers could you have multiplied are 9 and 2

Let the numbers be x and y

So, we have:

[tex]\mathbf{x \times y}[/tex]

Increase x by 1 and reduce y by 1.

So, we have

[tex]\mathbf{(x +1) \times (y -1) = 6 + xy }[/tex]

Open brackets

[tex]\mathbf{xy -x + y - 1 = 6 + xy}[/tex]

Subtract xy from both sides

[tex]\mathbf{ -x + y - 1 = 6}[/tex]

Collect like terms

[tex]\mathbf{ -x + y = 6 + 1}[/tex]

[tex]\mathbf{ -x + y = 7}[/tex]

Rewrite as:

[tex]\mathbf{ y -x= 7}[/tex]

The above means that, the difference between the integers is 7.

Answer:

90 cm

Step-by-step explanation:

We know that half of QS is x+25 and half of diagonal PR is 2x+5.

We can tell that x+25 = 2x+5 because both of these are sides of an isosceles triangle ORS. Since we know that, we can find out the diagonal QS by finding x.

2x+5 = x+25 => x = 20

Half of diagonal QS = 20 +25

= 45

Then we can double the half of diagonal QS to find out the diagonal QS.

45 x 2 = 90

Answer:

Slope = 2 and y-intercept = 8

Step-by-step explanation:

Use slope formula

m=y2-y1/x2-x1

m=16-12/4-2

m=4/2

Simplify

m=2

To find the y-intercept use point slope formula

y-y1=m(x-x1)

y-12=2(x-2)

y-12=2x-4

Add 12 to both sides

y=2x+8

So, 8 is the y-intercept or (0,8)

Aryabhata, also called Aryabhata I or Aryabhata the Elder, (born 476, possibly Ashmaka or Kusumapura, India), astronomer and the earliest Indian mathematician whose work and history are available to modern scholars. He is also known as Aryabhata I or Aryabhata the Elder to distinguish him from a 10th-century Indian mathematician of the same name. He flourished in Kusumapura—near Patalipurta (Patna), then the capital of the Gupta dynasty—where he composed at least two works, Aryabhatiya (c. 499) and the now lost Aryabhatasiddhanta.

Aryabhatasiddhanta circulated mainly in the northwest of India and, through the Sāsānian dynasty (224–651) of Iran, had a profound influence on the development of Islamic astronomy. Its contents are preserved to some extent in the works of Varahamihira (flourished c. 550), Bhaskara I (flourished c. 629), Brahmagupta (598–c. 665), and others. It is one of the earliest astronomical works to assign the start of each day to midnight.

Aryabhatiya was particularly popular in South India, where numerous mathematicians over the ensuing millennium wrote commentaries. The work was written in verse couplets and deals with mathematics and astronomy. Following an introduction that contains astronomical tables and Aryabhata’s system of phonemic number notation in which numbers are represented by a consonant-vowel monosyllable, the work is divided into three sections: Ganita (“Mathematics”), Kala-kriya (“Time Calculations”), and Gola (“Sphere”).
