Answer:
40
Step-by-step explanation:
The angle marked x is an exterior angle of the polygon.
The sum of the measures of the exterior angles of a polygon, one exterior angle per vertex, is 360 deg.
In a regular polygon, all exterior angles are congruent. The number of exterior angles, one per vertex, is the same as the number of sides.
We count the number of sides of this polygon and see it has 9 sides.
Since it is a regular polygon, he measure of each exterior angle is 360 divided by the number of sides.
x = 360 deg/9 = 40 deg

A class of x students are going on a treasure hunt and need to be separated into four groups. Which expression could be used to determine the total number of students in each group?
Answer:
X/4
Step-by-step explanation:
The number of students (X) would have to be divided by 4 (the number of groups), meaning the number of students in each group must be:
the total number of students (X)÷ the number of groups (4)
Peyton wanted to buy a new game. The game costs $65.00 before sales tax. If the sales tax is 8%, how much will she pay for the game?
Answer:
$70.20
Step-by-step explanation:
8% = .08
$65 times the tax rate of .08 = $5.20
$65 + $5.20 = $70.20
Dan wants to paint the ceiling of his restaurant. The ceiling is in the shape of a square. Its side lengths are 24 feet. Suppose each can of paint will cover 192 square feet. How many cans will he need to paint the ceiling?
Answer:
He will need exactly 3 cans of paint.
Step-by-step explanation:
You multiply 24 by 24, and you get 576, then you divide 576 by 192 and you get exactly 3.

The function f (x) = x2 with a vertical stretch of 8.5, a translation left 4 units and a translation 2 units down. Write the function g(x) that represents the transformations.
Answer:
g(x)=8.5([tex]x^{2}[/tex]+4)
Step-by-step explanation:
vertical stretch means to put that number in front like this:
8.5(x^2)
Then 4 units to the left means it will look like this. (Translation to the left is plus in the parentheses and for the right it's negative in the parentheses.)
8.5(x^2+4)
So you full equation is:
g(x)=8.5(x^2+4)
Graph y=x+7 by plotting the y-intercept at (0, 7). Use the slope of 1 to count up 1 space and to the right 1 space to plot the second point. Graph y=3x+5 by plotting the y-intercept at (0, 5). Use the slope of 3 to count up 3 spaces and to the right 1 space to plot the second point. Question 2 What is the solution of the system?
Answer:
A is the easiest way to graph the equation

What is the length of said JL
Answer:
13
Step-by-step explanation:
pythagorean theorem: a^2 + b^2 = c^2
5^2 + 12^2 = c^2
169=c^2
13=c
it's also special right triangle 5-12-13 (it's just something u remember)
Answer:
JL = 13
Step-by-step explanation:
a² + b² = c²
5² + 12² = c²
25 + 144 = c²
169 = c²
√169 = c
13 = c
JL = 13

9514 1404 393
Answer:
(x, y) = (7, 2)
Step-by-step explanation:
We assume you want the solution to this system of equations.
Since you're seeking help from "technology", it is appropriate to use the technology of a graphing calculator to find the solution. The attachment shows it to be (x, y) = (7, 2).
__
The coefficient of x in the first equation is 1, so it is convenient to use that equation to write an expression for x:
x = 4y -1 . . . . . add 4y to the equation
3(4y -1) +5y = 31 . . . . substitute for x in the second equation.
17y = 34 . . . . . . . . . . . simplify, add 3
y = 2 . . . . . . . . divide by 17
x = 4(2) -1 = 7 . . . . use the equation above to find x
The solution is (x, y) = (7, 2).

Given the function h(x) = 4x, Section A is from x = 0 to x = 1 and Section B is from x = 2 to x = 3. Part A: Find the average rate of change of each section. (4 points) Part B: How many times greater is the average rate of change of Section B than Section A? Explain why one rate of change is greater than the other. (6 points) (10 points)
Answer:
Part A. 4/1 ( 4 over 1 ) and -4
Part B. it is -1 times greater. It is -1 times greater because the values are higher.
Step-by-step explanation:
Average rate of change formula is change in f(x) values over corresponding change in x values
Part A.
first make a table.
X - 0, 1
f(x) - 0, 4
To figure out the y f(x) values you plug the first x value into x in the function h(x)=4x like h(x)=4(0) and you get 0...and plug in the next x value into the function h(x)=4x like h(x)=4(1) and you get 4.
You now have the coordinates (0,0) and (1,4) and now to find the average rate of change you put 4 - 0 / 1 - 0 ( 4 - 0 over 1 - 0) and solve so 4-0=4 and 1-0=1 the average rate of change for this is 4/1.
For B you do the same thing.
Hope this helped!

Determine the unknown angle measure 8th grade
9514 1404 393
Answer:
a. m∠C = 44°
b. m∠P = 60°
Step-by-step explanation:
In each case, the missing angle brings the sum of angles to 180°. So, its value is the difference between 180° and the sum of the given angles.
a. m∠C = 180° -90° -46°
m∠C = 44°
__
b. m∠P = 180° -110° -10°
m∠P = 60°
