Answers

first, find 25% of 60 using 60*0.25

60*0.25 = 15

now subtract that from the original price
60 - 15 = 45

so the sale price of the tennis racket after the discount is $45

Write the equation of a line that is perpendicular to 2x-7y=13 and which passes through the point ( -3,8).

Answers

Given parameters:

Equation of the line given  2x - 7y = 13

Coordinates of points = -3, 8

Unknown:

Equation of a line perpendicular = ?

Solution;

 To find the equation of this line, simply find the negative inverse of the given line.

         m  = [tex]-\frac{1}{m}[/tex]

          2x - 7y = 13 , this is an equation of a straight line

  let us write it in the form y = mx + c so as to derive the slope

        y and x are coordinates

         m is the slope

        c is the y intercept

  2x - 7y = 13;

        -7y = -2x + 13

  divide through by -7;

             y = [tex]\frac{2}{7}x[/tex] + [tex]\frac{13}{7}[/tex]

The slope of this line is [tex]\frac{2}{7}[/tex];

           Now the slope of a line perpendicular to it will be [tex]-\frac{7}{2}[/tex];

  the equation of the line will be;

        y  = [tex]-\frac{7}{2} x + C[/tex]

Since the coordinate of this line is (-3,8) , let us find C;

     y  = 8 and x = -3;

     8  = [tex]-\frac{7}{2}[/tex] (-3) + C

         multiply through by 2;

 

    16 = 21 + 2C

    16 - 21  = 2C

      -5 = 2C

        C  = [tex]\frac{-5}{2}[/tex]

Now the equation of the line is;

              y  = [tex]-\frac{7}{2} x + \frac{5}{2}[/tex]

The formula for the length of the hypotenuse in a right triangle is where and bare the lengths of the triangle's sides this form is derived from the Pythagorean theorem) From the side, a certain ramp has a right-triangular shape. Its height is 30 centimeters and its horizontal length is 3 meters. What calculation will give us the estimated length of the ramp in meters? on Khan academyI know the answer is because I I want people to know the answer on Khan academy but you can add more answers
[tex] {30}^{2} \div {100}^{2} + {3}^{2} [/tex]
​

Answers

Answer:

3m

Step-by-step explanation:

The length of the ramp will be the longest side of the right-triangular shape (the hypotenuse). The height and the horizontal length will be the other two sides (adjacent and opposite).

Acording to the theorem;

hyp² = opp²+adj²

Given

opp = 30cm = 0.3m (convert to metres)

adj = 3 m

Substitute

hyp² = 0.3²+3²

hyp² = 0.09+9

hyp² = 9.09

hyp = √9.09

hyp = 3.0145 m

Hence the estimated length of the ramp in meters is 3m

The points on a section of an exam are given by the function f(x), where x is the number of questions answered correctly in that section. If [tex]f(12)=18[/tex], then a test-taker receives 18 points for answering _____ questions in the sections correctly.

Express the statement "A rectangular field with an area of 120m' has it length 12mn longer than the width" as quadratic equation.

Answers

Answer:

The quadratic equation is x^2 -12x -120 = 0

where x represents the length of the field

Step-by-step explanation:

We want to make an expression in terms of a quadratic equation;

Let the length of the field be x mm , then the width will be (x-12) mm

Mathematically , the area of the field will be L * B

Thus;

x * (x-12) = 120

That gives;

x^2 -12x = 120

x^2 -12x -120 = 0

Step-by-step explanation:

Solve for the first variable in one of the equations, then substitute the result into the other equation.

Answer:

10

Step-by-step explanation:

You must substitute the 3 for the x in f(x) = 2x+1 first

f(x) = 7

Then substitute the 7 for the x in g(x) = (3x - 1)/2

g(x) = 10

How do you find the angle measure?

Answers

Answer:

∠ XYZ = 41°

Step-by-step explanation:

∠ XYZ = ∠ 3x + 20 ( corresponding angles ) , thus

8x - 15 = 3x + 20 ( subtract 3x from both sides )

5x - 15 = 20 ( add 15 to both sides )

5x = 35 ( divide both sides by 5 )

x = 7

Thus

∠ XYZ = 8x - 15 = 8(7) - 15 = 56 - 15 = 41°
