Answer:

27 1/3

Step-by-step explanation:

The polygon has a perimeter of 164 and 6 sides.

Divide 164 by 6 sides to get the side lengths for each side.

164/6 = 27 1/3

Final answer:

To find the length of a side of a regular hexagon with a perimeter of 164 meters, you divide the perimeter by the number of sides, which results in approximately 27.33 meters per side.

Explanation:

The regular polygon in question is a hexagon since it has 6 sides. To find the length of one side of the polygon, we divide the perimeter of the polygon by the number of sides it has. The formula for the perimeter (P) of a regular polygon is P = number of sides × length of one side.

Given the perimeter (P) is 164 meters, we find the length of one side (s) by dividing the perimeter by the number of sides (6).

Length of one side (s) = P / number of sides = 164 / 6 = 27.333... meters

Therefore, the length of one side of the hexagon is approximately 27.33 meters.

Answer:

y = -3x +7

Step-by-step explanation:

The y intercept is 7.  It is where the line crosses the y axis

We also need to find the slope

We need two points (0,7) and (3,-2)

m = (y2-y1)/(x2-x1)

   = (7 - -2)/(0-3)

  (7+2)/(0-3)

  9/-3

 -3

The equation of a line is

y = mx+b  where m is the slope and b is the y intercept

y = -3x +7

Answer:

Step-by-step explanation:

Multiplying bases with exponents means you have to multiply the base and add the exponent. So:

(10⁴)(5²) = 50⁶

(10³)(5³) = 50⁶

Now the equation is (50⁶/50⁶)³

Anything divided by itself will be one, so the number inside the parentheses is 1.

Now the equation is 1³, and 1x1x1 is 1.

The value of the solution of the expression (x³ y²)⁴ is, x¹² y⁸.

Used the rule of the exponent to solve the equation that states,

[tex](x^{m} )^n = x^{m \times n}[/tex]

[tex](xy)^{m} = x^m \times y^m[/tex]

Given that,

The expression is,

(x³ y²)⁴

Now apply the rule of the exponent to solve the equation as

[tex](x^3 y^2)^4[/tex]

It can be written as,

Answer: 60

Step-by-step explanation:

The three interior (inside) angles in a triangle will always add up to 180°.

60 + 60 + y = 180

120 + y = 180

-120

y = 60

60 * 3 = 180

Answer:

B. 60

Step-by-step explanation:

It is an equilateral triangle, meaning all sides and angles are equal. This also means that if the angle of point B is 60°, then the angle of points C and A are also 60°.

The correlation coefficient is a number that indicates the direction

and closeness of points of a line of best of fit.

So it tells us two things.

It tells us the direction of the line of best fit

and it tells us the closeness of the points.

Usually, anything between -0.9 and -0.6 has a moderate negative correlation. If you look at this on a graph, you will notice that the points definitely resemble a line so we say it's moderate.

It will be a negative correlation because the slope is negative.

Your answer would be 56m².

To find the surface area, you need to add up the total number of squares that can be seen on the outside of the solid.

First you have the front end which is made up of 4 squares, and there would be another one on the same side, so this comes to 8m².

The surface on top contains 12 squares, and this would also be the same on the bottom of the solid, so you get 24m².

The surface on the right-hand side also contains 12 squares and would be doubled on the other side, so this also comes to 24m².

Therefore your final answer is 8 + 24 + 24 = 56m².

80 Miles.

The real distance between these cities is in miles if a map is drawn with a scale of 1/2 inch is equal to 5 actual miles. If the map distance between two cities is 8 inches is 80 miles.

One of the four fundamental mathematical operations, along with addition, subtraction, and division, is multiplication. Multiply in mathematics refers to the continual addition of sets of identical sizes.

Given:

The distance between two cities = 8 inches,

The scale 1 / 2 inches or 0.5  = 5 miles

So for 1 inch, the actual distance will be 2 × 5 = 10 miles,

Hence, for 8 inches the distance will be =  8 × 10 = 80 miles,

Therefore, the real distance between these cities is in miles if a map is drawn with a scale of 1/2 inch is equal to 5 actual miles. If the map distance between two cities is 8 inches is 80 miles.

Answer:

f(-4)= -55

Step-by-step explanation:

We want to find f(x), or y, when x is equal to -4.

Therefore, we can substitute -4 in for x in the function.

f(x) = -2x^2 + 4x - 7

Substitute -4 in for x

f(-4) = -2(-4^2) + 4(-4) - 7

Evaluate the exponent

f(-4)=-2(16)+4(-4)-7

Multiply -2 and 16

f(-4)= -32+4(-4)-7

Multiply 4 and -4

f(-4)=-32-16-7

Subtract

So expression could be f(t) 2 x 1t x 5 = 10

Step-by-step explanation:

The expression for the number of chips Tyler won, based on the number of chips Jada won, is 2j.

In this problem, we are asked to develop an expression for the number of chips Tyler won based on the amount Jada won. The relationships between the chips won are as follows: Kiran won as many chips as Jada (so if Jada won j chips, Kiran also won j chips), Mai won 4 times as many chips as Kiran (so Mai won 4j chips), and Tyler won half as many chips as Mai (so Tyler won 1/2 * 4j = 2j chips).

So, using j to represent the number of chips Jada won, the expression for the number of chips Tyler won would be 2j.

Answer:

Vertex is (2,-9)

Y- intercept is (0,-5)

Step-by-step explanation:

The vertex of the parabola are (2, -9).

The x-intercepts: (–1, 0) and (5, 0).

The midpoints between the intercept are (2, 0).

The y-intercept is (0, -5).

The equation of the vertex of the parabola;

y = a (x - h)² + k

Where h and k are the vertexes of the parabola.

Given that;

Graph the function f(x) = (x + 1)(x – 5).

Now, Comparing this to the general form, the vertex is (2, -9).

And, The x-intercept is the point where the graph intersects the x-axis or the point where y or f(x) is 0.

f (x) = 0

(x + 1) (x - 5)= 0

x = - 1

x = 5

Thus, The x-intercepts: (–1, 0) and (5, 0).

The midpoints between the intercept are;

(- 1 + 5) / 2, (0 + 0)/2

(2, 0)

Hence, The midpoints between the intercept are (2, 0).

The y-intercept is the point where the graph intersects the y axis or the point where x is 0.

f(0) = (0+1). (-5) = 1(-5) = -5

The y intercept is (0, -5).

David's winnings decrease faster Between 4.5 and 6 hours since he started playing. so option B is correct.

The average Rate of Change of the function f(x) can be calculated as;

[tex]f(x) = \dfrac{f(b) - f(a)}{b-a}[/tex]

David played a slot machine.

W(t) models his winnings (in dollars, where a negative number means David is losing) as a function of time t (in hours).

Lets calculate the average rate of change of W(t).

ARC ( 1, 4.5)

[tex]W(t) = \dfrac{W(4.5)- W(1)}{4.5-1}\\\\W(t) = \dfrac{-70}{3.5}\\\\W(t) = -20\\[/tex]

ARC( 4.5, 6)

[tex]W(t) = \dfrac{W(6)- W(4.5)}{6-4.5}\\\\W(t) = \dfrac{-51}{1.5}\\\\W(t) = -34\\[/tex]

Thus, the average rate of change over the interval ( 4.5, 6) is greater than the average rate of change over the interval ( 1, 4.5).

Hence, David's winnings decrease faster Between 4.5 and 6 hours since he started playing.

Answer:

It is equivalent to 15x – 3)(2x + 1) = 0.       False

It is equivalent to (5x – 3)(2x + 1) = 0        True

Either   x=-1/2   or    5/3

Step-by-step explanation:

Consider the equation 5x (2x + 1) - 3(2x + 1) = 0.

It is equivalent to 15x – 3)(2x + 1) = 0.       False

It is equivalent to (5x – 3)(2x + 1) = 0        True

When you take pull-out (2x+1), you will be left with (5x-3)

5x (2x + 1) - 3(2x + 1) = 0.

(2x+1)(5x-3)=0

Either 2x + 1 = 0                        

2x = -1    

Divide both-side of the equation by 2

2x/2 = -1/2                                    

  x= -1/2                                        

OR

5x-3 =0

5x = 3

Divide both-side of the equation by 5

5x/5 = 3/5

x = 5/3

Either   x=-1/2   or    5/3
