lol

Answer:
x = 15
Step-by-step explanation:
4x + 2 + 58 + 60 = 180
4x + 120 = 180
4x = 60
x = 15
Answer:
x = 15
Step-by-step explanation:
=> (4x+2)°+60°+58° = 180° { angle sum property }
=> 4x+2+118 = 180
=> 4x +120 = 180
=> 4x = 180-120
=> x = 60/4
=> x = 15

120 of the 720 students travelled on foot
What is a pie chart?
A pie chart is a graph or chart that graphically represents data in a circle with each pie slice showing the size of data.
From the pie chart attached, the proportion of students that walked is 60°, hence for 720 students:
Number of those who travelled on foot = (60 / 360) * 720 = 120
120 of the 720 students travelled on foot

Step-by-step explanation:
Try creating a triangle using the length of x and the length of y, so, you can tell the line goes from -5 to 5 on the x axis so that means its 10 long on x and 0 to 6 on y axis so its 6 long on y... then create a triangle and use the pythagorean theorem (the square root of (10 squared + 6 squared) which is around 11.7 .... i think, hope that helps! -prowl

The polygons are regular polygons. Find the area of the shaded region.
Answer:[tex]194.8557 in^2[/tex]
The side of a regular hexagon is congruent with the radius of the circle the hexagon is inscribed with. That makes the two triangles in red and green (lines are a bit offset for clarity) equilateral. At this point it's easy to compute the area of an equilateral triangle known the side length l, which is [tex]A = \frac12 l (l\frac{\sqrt3}2) = \frac{\sqrt3}4 l^2[/tex] At this point, the area of the shaded region of one triangle making up the hexagon is obtained by difference (area of the red triangle, minus area of the white:
[tex]A=A_r-A_w = \frac{\sqrt3}4 10^2 -\frac{\sqrt3}45^2 = \frac{\sqrt3}4(10^2-5^2)=\frac{\sqrt3}4\times 75\approx 32.47595[/tex]
The area of the whole shaded region, is 6 times that, or [tex]194.8557[/tex]
With tasselation:
Join the midpoint of the side of the external hexagon with the end points of the corresponding side of the inner hexagon. You have now created four equilateral squares which are congruent. (yes, my drawing skills are terrible)
The shaded region is made of 18 triangular tiles, each having an area of (see above formula) [tex]\frac{\sqrt3}4\times 5^2 = 18.8253[/tex], for a total of, again, 194.8557 square inch.

Hello!
Formula for the Area of a Square:
[tex]\bf{A=a^{2}[/tex]
A = area
a = the length of a side of a square
Since we have the area, all we have to do to determine the side length is take the square root of both sides:
[tex]\bf{\sqrt{82} =\sqrt{a^{2} }[/tex]
Solve:
[tex]\bf{\sqrt{82} =a[/tex]
[tex]\bf{a=\sqrt{82}[/tex]
[tex]\bf{a=9.06}[/tex]
Final Answer:
a≈9.06

elect the correct answer from each drop-down menu. A system of linear equations is given by the tables. x y -5 10 -1 2 0 0 11 -22 x y -8 -11 -2 -5 1 -2 7 4 The first equation of this system is y = x. The second equation of this system is y = x − . The solution to the system is ( , ).
Answer:
First equation: y = -2x
Second equation: y = 3 - x
Solution: (1, -2)
Step-by-step explanation:
Assuming the ordered pairs of the tables are:
Table 1
(-5, 10) (-1, 2) (0, 0) (11, -22)
Table 2
(-8, -11) (-2, -5) (1, -2) (7, 4)
To create a linear equation, pick 2 ordered pairs. Calculate the slope by using the slope formula, then use the points-slope form of the linear equation to form the equation.
[tex]\textsf{slope }m=\dfrac{\textsf{change in }y}{\textsf{change in }x}[/tex]
[tex]\textsf{point-slope form : }y-y_1=m(x-x_1)[/tex]
Equation 1
[tex]\textsf{slope }m=\dfrac{2-10}{-1+5}=-2[/tex]
[tex]y-0=-2(x-0)\\\\\implies y=-2x[/tex]
Equation 2
[tex]\textsf{slope }m=\dfrac{-5+11}{-2+8}=1[/tex]
[tex]y+11=1(x+8)\\\\\implies y=x-3[/tex]
Solution to the System
Equate the equations and solve for x:
-2x = x - 3
⇒ 0 = 3x - 3
⇒ 3x = 3
⇒ x = 1
Substitute found value of x into one of the equations and solve for y:
y = 1 - 3 = -2
Therefore, the solution is (1, -2)
The equations are given as follows:
First equation : y = -2 xSecond equation : y = x - 3Solution of the given system of equations is (1, -2).An equation is a combination of expressions that are equal to each other.
The ordered pairs of the tables are as follows:
Table 1:
(-5, 10), (-1, 2), (0, 0), (11, -22)
Table 2:
(-8, -11), (-2, -5), (1, -2), (7, 4)
To obtain the first equation, pick any two ordered pairs.
The slope of the equation is given as:
[tex]m = \dfrac{y_2-y_1}{x_2-x_1}[/tex]
Let's pick ordered pairs (-1, 2) and (0, 0) to find the slope of the equation.
Then,
[tex]m = \dfrac{0-2}{0-(-1)}\\m = \dfrac{-2}{1}\\\\m = -2[/tex]
So, the first equation in the point-slope form is given as follows:
[tex]y-y_1= m({x-x_1})[/tex]
Substitute [tex](x_1,\ y_1)[/tex] by (0, 0) and m by -2,
y - 0 = -2(x - 0)
y = -2x
Similarly, the slope of the second equation is obtained as follows:
[tex]m = \dfrac{-5-(-11)}{-2-(-8)}\\m = \dfrac{6}{6}\\\\m = 1[/tex]
So, the second equation in the point-slope form is given as follows:
y - (-11) = 1(x - (-8))
y + 11 = x + 8
y = x - 3
To solve this system of equations, let's equate the right-hand sides of both equations:
-2x = x - 3
-2x -x = -3
-3x = -3
x = 1
Substitute this value of x in the first equation,
y = -2 × 1
y = -2
So, the solution is (1, -2).
Therefore, the blanks are filled in by the numbers -2 and 3. The solution of the system of equations is (1,-2).

The top of a cube has an area of 25 square inches. What would be the length of one of its sides, s, be?
PLEASE SHOW WORK TYY
Answer:
The length of one of the sides would be 5 in.
Step-by-step explanation:
Every cube has 6 faces. Each of those faces is a square.
Since all the sides of a square are equal, we can figure out the length of one of them by looking at the area.
The area of the square is 25 square inches.
The formula to find the area is length times width or l · w
Since all of the sides have to be equal, we just have to find a number that can be multiplied by itself to get 25.
Well, 5 can be multiplied by itself to get 25.
5 x 5 = 25
So, the length of one of the sides would be 5 inches.
