Answer:

Ankita is 135cm tall and Nita is 150cm tall- to find what percent of Nita's height Ankita represents you would divide ankita's height by Nita's height then multiply the answer by 100%

135cm/150cm = 0.9 (the centimetres cancel out and leaves a generic unit) then 0.9 x 100% = 90%

so Ankita is 90% of the height of Nita

The equations of the lines given in the graph will be y = 3x and y =-5x -2.

What is an equation of the line?

An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.

The general form of the equation of the line:-

y = mx + c

m = slope

c = y-intercept

Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )

For line one the points are:-

( 1,3 ) and ( 0,0)

Slope = ( 0 - 3) / ( 0 - 1 )

Slope = 3

The equation will be,

y = 3x

For line two the points are:-

(-1,3) and (0,-2),

Slope = ( -2 - 3 ) / ( 0 + 1)

Slope = -5

The y-intercept will be,

y = mx +c

c = -2

The equation can be written as:-

y = -5x - 2

Find the arc length of the partial circle.
units

Answers

Answer:

How to solve ???

Arc Length = θ × (π/180) × r, where θ is in degree.

Radius and the sector area:-

Multiply the sector area by 2.Then divide the result by the radius squared (the units should be the same) to get the central angle in radians.Multiply the central angle by the radius to get the arc length.

Let's solve ur question :-

Answer :-

The Arc length of the given partial circle is 4π units or 12.56 units .

Used formulae :-

The length of the Arc is "I" units , the radius "I" units and the angle subtended by the Arc at the center is "X" is ( X° / 360° ) x 2πr units .

3х + 9 = 2х + 5

is it no solutions, all real numbers, or does x equal something?

Answers

Answer:

x = -4

Step-by-step explanation:

Given Equation:3x + 9 = 2x + 5

Question:Whether x has one solution or infinite solutions or no solutions?

Solution:

=> 3x + 9 = 2x + 5

(On shifting like terms to one side we get)

=> 3x - 2x = 5 - 9

(On subtracting)

=> x = - 4

Result:

Hence, x has only one solution that is, x = -4 (Ans)

Topic : Linear equations in one variable

Given :

3х + 9 = 2х + 5

Solution :

[tex]\qquad \sf \: { \dashrightarrow 3x + 9 = 2x + 5}[/tex]

Transposing variables on one side and constant terms on the other side, we get :

PLEASE HELP ME WILL GIVE BRAINLIEST FOR RIGHT ANSWER​

Answers

Answer:

Step-by-step explanation:

I dont really know how to find out the variables but what i assume to do is this:

Find the square root of n and add it to m. The sum of both you divide by p. then when you figure that out, you distribute the x value into the parenthesis. This might be obvious but i looked at this question for 10 minutes and couldnt  find the value sorry :(

Answer:

m = 11
n = 145
p = -4

As you substitute the equation -2x^2 – 11x + 3 = 0 (from factorising x(-2x-11) = -3) into the quadratic formula to find the values of m, n and p.

What is the slope of a line perpendicular to the line whose equation is -2x+20y=6​

Answers

Answer:

  -10

Step-by-step explanation:

Solving for y gives ...

  20y = 2x +6

  y = 2/20x +6/20 = 1/10x +3/10

The slope of the given line is the coefficient of x: 1/10. The slope of the perpendicular line is the opposite reciprocal of this: -1/(1/10) = -10.

The perpendicular line has a slope of -10.
