The perimeter of Stephanie’s triangle is half the perimeter of Juan’s triangle. Juan’s triangle is shown. Write a numerical expression to describe the perimeter of Stephanie’s triangle.
Answers
The perimeter of a triangle is the sum of all side lengths of the triangle. The numerical expression for the perimeter of Stephanie's triangle is: [tex]\frac 12 \times 25[/tex]
Let the sides of Juan's triangle be x, y and z. So:
[tex]x = 5 \\ y = 8\\ z = 12[/tex]
The perimeter (J) of Juan's triangle is calculated by adding all sides.
So:
[tex]J =x +y +z[/tex]
This gives:
[tex]J =5 + 8 + 12[/tex]
[tex]J =25[/tex]
From the question, we understand that:
The perimeter (S) of Stephanie's triangle is half that of Juan.
This means that:
[tex]S = \frac 12J[/tex]
Substitute 25 for J
[tex]S = \frac 12 \times 25[/tex]
Hence, the numerical expression for the perimeter of Stephanie's triangle is: [tex]\frac 12 \times 25[/tex]

What is the difference between (-5,-6) and (-3,-8)?
please provide steps and I will give Brainliest
Answers
d = √8
Step-by-step explanation:
d = √((x2 - x1)² + (y2 - y1)²)
points: (-5, -6) and (-3, -8) where the first point “(-5, -6)” = (x1, y1) and the second point “(-3, -8)” = (x2, y2)
d = √((-3 - -5)² + (-8 - -6)²)
d = √((2)² + (-2)²)
d = √(4 + 4)
d = √8
Point B is on line segment AC. Given AB=4x-6, AC=2x+10, and BC=4, determine the numerical length of AC
Answers
Answer:
AC = 22
Step-by-step explanation:
AB + BC = AC , substitute values
4x - 6 + 4 = 2x + 10 , that is
4x - 2 = 2x + 10 ( subtract 2x from both sides )
2x - 2 = 10 ( add 2 to both sides )
2x = 12 ( divide both sides by 2 )
x = 6
Then
AC = 2x + 10 = 2(6) + 10 = 12 + 10 = 22

Answers
Answer:

Step-by-step explanation:
hopefully it makes sense and is visible:)
====================================================
Work Shown:
C = 2*pi*r .... circumference equation
6pi = 2pi*r .... replace C with the given circle perimeter
6 = 2r .... divide both sides by pi, they cancel
6/2 = r
3 = r
r = 3 ... is the radius
------------
A = pi*r^2 .... area of circle equation
A = pi*3^2
A = pi*9
A = 9pi .... which points to choice B as the final answer

elena bikes 20 minutes each day for exercise write and equation to describe the relationship between her distance in miles d and her biking speed in miles per hour when she bikes at a constant speed of 15 miles per hour for the first 5 minutes then at 12 miles per hour for the last 15 minutes
Answers
The equation to describe the relationship between Elena distance:
a) D = 4.34 miles, b) D = 4.25 miles and c) 12D = M + 3N miles.
Solution:
Given, Elena bikes 20 minutes each day for exercise.
We have to write an equation to describe the relationship between her distance in miles, D, and her biking speed, in miles per hour,
We know that, distance travelled = speed time
a. At a constant speed of 13 miles per hour for the entire 20 minutes
Her speed is 13 miles per hour.
Then, distance D miles = 13 miles per hour 20 minutes
b. At a constant speed of 15 minutes per hour for the first 5 minutes, then at 12 miles per hour for the last 15 minutes
Now, total distance travelled = distance travelled with 15 mph + distance travelled with 12 mph
c. At a constant speed of M miles per hour for the first 5 minutes, then at N miles per hour for the last 15 minutes
Now, total distance travelled = distance travelled with M mph + distance travelled with N mph
Hence, a) D = 4.34 miles, b) D = 4.25 miles and c) 12D = M + 3N miles.

Jessica is selling books during the summer to earn money for college. She
earns a commission on each sale but has to pay for her own expenses.
After a month of driving from neighborhood to neighborhood and walking
door-to-door, she figures out that her weekly earnings are approximately a
linear function of the number of doors she knocks on.
She writes the equation of the function like this: E(x) = 10x - 30, where x is the
number of doors she knocks on during the week and E(x) is her earnings for
the week in dollars.
Which of the following are reasonable interpretations of the y-intercept of
Jessica's function?
Check all that apply:
A.) If she does not knock on any doors at all during the week, she will lose $30
