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]
Answer:
3mStep-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

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

Given that f(x)=2x+1 and g(x)=3x-1/2 find g(f(3))
1. 5
2. 7
3. 9
4. 10
Answer:
7
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

Rearrange the equation by subtracting what is to the right of the greater than sign (≤, ≥) from both sides of the inequality:[tex]-3*x-(9)<0[/tex]
Pull out like factors:[tex]-3x - 9 = -3 * (x + 3)[/tex]
Divide both sides by [tex]-3[/tex]: Remember to flip the inequality sign:[tex]<=>[/tex]
Subtract [tex]3[/tex] from both sides:[tex]x > -3[/tex]

How do you find the angle measure?
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°

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