A triangle has side lengths of,x, x+1, and 11. Find each side length when the perimeter is 30 inches
The sides of the triangle whose perimeter is 30 are given by-
[a] = 9 , [b] = 10 , [c] = 11.
What is the perimeter of triangle?
The perimeter of triangle is the sum of its sides. Mathematically -
Perimeter [P] = a + b + c
Given is a triangle whose side measurements are x, x + 1, and 11. The perimeter of triangle is 30 inches.
From the definition of the perimeter of a triangle -
Perimeter = sum of its sides
x + (x + 1) + 11 = 30
x + x + 1 + 11 = 30
2x + 12 = 30
2x = 18
x = 9
Now -
Length of side 1 = [a] = 9
Length of side 2 = [b] = 10
Length of side 3 = [c] = 11
Therefore, the sides of the triangle whose perimeter is 30 are given by-
[a] = 9 , [b] = 10 , [c] = 11.

Slope m₁ = 2/3 and y intercept is 2.
For the relation of slope;

Write the equation in slope intercept form;
-2y = 3x + 4
y = (-3/2)x - 2
m₂ = -3/2
m₁ ≠ m₂ as 2/3 ≠ -3/2
m₁×m₂ = 2/3 × -3/2 = -1
Thus, the both lines are perpendicular.
Part b: -2x + 3 y = -6
Write the equation in slope intercept form;
3y = 2x - 6
y = (2/3)x - 2
m₂ = (2/3)
m₁ = m₂
Thus, both lines are parallel.

The average rate of change of helicopters height when it starts descending is : - 630.01 ft/min
Solution:Rate of change between two points,
We calculate the average rate of change by dividing the change in y (output) by the change in x. (input). And all we're doing visually is calculating the slope of the secant line that connects two points.Follow these steps to calculate the rate of change on a graph when given two points on the graph:
Determine the coordinates of the given points.Determine the difference in the output values.Determine the difference in the input values.Determine the ratio of the change in y to the change in x: ΔyΔx.Here in the question ,
Given two points (0 , 8400) and (13.333 , 0)
to find the average rate of change ,
Average rate of change = y2 - y1/ x2 - x1
by substituting values,
Average rate of change = 0 - 8400/ 13.333 - 0
= - 8400 / 13.333
= - 630.01 ft/min
since the helicopter is descending the rate of change will be negative

Skeletal muscle is striated, similar to cardiac muscle; it has long, thin, multinucleated fibers that are crossed in a regular manner by fine red and white lines that give the muscle its unique look. Myofibrils, which are made up of sarcomeres joined in series, make up muscle fibers. The arrangement of actin and myosin filaments, which results in the banding pattern of myofibrils, produces the striations of skeletal muscle. The ability of muscular tissue to contract is special.

mrs green wants to use wood to make a fence around her circular garden. Her garden has a radius of 16 feet How much wood will she need to enclose her garden?.
ANSWER
100.5 feet
EXPLANATION
The radius of the circular garden is 16 feet.
To find how much wood she would need to make a fence around the garden, we need to find the circumference of the garden.
Circumference can be found using the formula:
[tex]C\text{ = 2}\pi r[/tex]where r = radius
Therefore:
[tex]\begin{gathered} C\text{ = 2 }\cdot\text{ }\pi\cdot\text{ 16} \\ C\text{ = 100.5 ft} \end{gathered}[/tex]She would need 100.5 ft length of wood to enclose the garden.

Arielle is hiking down into the canyon. She starts at the rim and hikes down 55 feet in 2 3/4 minutes. If she continues at this rate, where will Arielle be in relation to the rim after 15 minutes
First, determine the speed of Arielle by calculating the quotient in between 55 ft and 2 3/4 minutes. To find the quotient, convert the mixed number to a normal fraction before:
[tex]2\frac{3}{4}=2+\frac{3}{4}=\frac{8+3}{4}=\frac{11}{3}[/tex]then, calculate the speed:
[tex]v=\frac{55}{\frac{11}{3}}=\frac{\frac{55}{1}}{\frac{11}{3}}=\frac{55\cdot3}{11\cdot1}=\frac{165}{11}=15[/tex]then, the Arielle's speed is 15 ft/min
next, find the distance traveled by Arielle in 15 min, by using the previous result:
[tex]d=v\cdot t=(15ft/\min )(15\min )=225ft[/tex]Hence, in relation to the rim, Arielle will be at 225 ft

To find the slope, choose any two points on the graph (no really IT DOESN'T MATTER WHICH ONE). Use the equation y-y/x-x to get the slope.
Ex. 8-3/5-1=4/3
(NOTE: Always write your answer as either an improper fraction or a whole number!)
To find the distance, go across the x-axis, however many units away the closest point is to your chosen point. Then, go across the y-axis for the required # of units. Next, find the total number of the x and y units. You can also subtract the smallest coordinate from the greatest if the two ordered pairs are in the same quadrant. If not in the same quadrant, add the coordinates together. If the value of x or y happens to be the same as your chosen coordinate, find the sum of the two numbers that are equal, or subtract if in the same quadrant.

Movie theaters keep track of how many tickets they sell. For the 5:30 showing, the theater
sold a total of 272 adult and student tickets and took in a total of 1694 dollars. If adults
tickets sold or 7 dollars and students sold for 4 dollars each how many of each type were sold
for the 5:30 show.
As a result, we deduce that 101 tickets were sold to adults and 171 to students after solving the algebraic equations.
What are Algebraic equations ?The term "algebraic equation" refers to a formulation of the equality of two expressions using the algebraic operations of addition, subtraction, multiplication, division, raising to a power, and extraction of a root on a set of variables.
A mathematical statement in which two expressions are rendered equal to one another is known as an algebraic equation.
So on the information provided to us:
we know that the total amount of the tickets sold =1694$
total no. of people = 272
Lets assume the no. of kids to be y and the adults to be x
So the first equation we get for the total no. of people is:
x+y=272...(i)
the next equation we get for the total amount of tickets sold will be equal to the no. of adults and children multiplied by the cost of each adult and child respectively :
7x+4y=1694....(ii)
Two solve both equations simultaneously , we multiply equation i with 4
we get:
4x+4y=1088
7x+4y=1694
on solving both the equations simultaneously we get
3x=606
x=101
putting value of x in equation (i) we get
y=171
Therefore, we conclude that the no. of tickets sold to adults were 101 and to students were 171.
