Answer:

There are 341 inches from  the perimeter of a pentagon train made from 85 pentagons

Step-by-step explanation:

A pentagon is a polygon with five sides. A regular pentagon have all the five sides equal in length and also all the five interior angles equal.

The perimeter of a pentagon = 5l

Nof for a pentagon train attached to 1 pentagon by its sides;

The perimeter = (5 × 1 - (1-1))

Perimeter = 5

For pentagon train attached to two pentagon

Perimeter = ( 5×2 - (2-1))

Perimeter = (10 1)

Perimeter = 9

For pentagon train with n pentagon

Perimeter = ( 5× n -(n-1))

Perimeter = 5n - n+1

Perimeter = 4n + 1

∴ For pentagon train attached to 85 pentagon; where n=85

Perimeter = 4 n + 1

Perimeter = (4 × 85)+1

Perimeter = 340+1

Perimeter = 341 inches

There are 341 inches from  the perimeter of a pentagon train made from 85 pentagons

Answer: 20 over 7 units

Step-by-step explanation:

Answer:

Step 3  they took the square root incorrectly

Step-by-step explanation:

5 ( x-2)^2 +6 = 86

Subtract 6 from each side

5 ( x-2)^2 +6 -6= 86-6

5 ( x-2)^2  = 80

Divide each side by 5

5 ( x-2)^2  /5 = 80/5

(x-2)^2 = 16

Take the square root of each side

sqrt((x-2)^2)  = ±sqrt(16)

x-2 = ±4

Answer:

The volume of the box would be 6x³+33x²+54x+27.

Step-by-step explanation:

The new dimensions of the box would be (x+3), (2x+3), and (3x+3). Since the volume of a rectangular prism are calculated by multiplying the length, width, and depth, we can just multiply all three of these dimensions together to come up with the answer.

Using foil on the first two terms originally you get (x+3)×(2x+3)= 2x²+3x+6x+9 which can be simplified to 2x²+9x+9.

Then you multiply this equation by (3x+3). (2x²+9x+9)×(3x+3)= 6x³+6x²+27x²+27x+27x+27 which can be simplified to 6x³+33x²+54x+27.

Answer:

The sine of cx in the triangle is the opposite side/the hypotenuse

sin(cx) = 7/25

sin(cx) = 0.28

cx = sin^-1 (0.28)

cx = 16.26 degrees

Answer:

R=T

Step-by-step explanation:

We could say that the same symbol = makes it look like a true statement.

We could say that the same symbol makes us see a true statement.

In this case we are showing that R corresponds to T therefore it is true or confirmed, regardless of the value that R has.

Answer:

C

Step-by-step explanation:

Answer:

x = 38.7

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

tan theta = opposite/ adjacent

tan x = 8/10

Take the inverse tan of each side

tan ^-1 ( tan x) = tan ^-1 (8/10)

x = tan ^-1 (8/10)

x =38.65980825

To the nearest tenth

x = 38.7

Answer:

38.7

Step-by-step explanation:

Answer:

10.5 cm

Step-by-step explanation:

Multiply the ratios by x

3x : 8x: 7x

Add the sides together

3x+8x+7x to get the perimeter

18x = 63

Divide each side by 18

18x/18 = 63/18

x =3.5

The shorter side is 3x

3*3.5=10.5 cm

The Answer is D. because -4 passes trough the x intercept and -2 passes through the y

Step-by-step explanation:

Answer:

The answers are:

x-intercept = -4

y-intercept = -2

Step-by-step explanation:

According to the following to graph, you need to find the x-intercept and the y-intercept. The x-intercept, is when a line crosses the x-axis of the graph, and the y-intercept, is when a line crosses the y-axis of the graph.

Finding the x-intercept and the y-intercept:

x-intercept = -4

y-intercept = -2

EDGE2020

Answer:

The correct answer is a) 0 and 1.

Step-by-step explanation:

By converting the fractions into decimals, we can see that -1/4 is equivalent to -0.25 and 3/2 equals 1.5. Therefore, anything with a value outside of -0.25 < x < 1 should be marked out. So, anything containing anything less than -0.25 cannot be considered (i.e., -1) and anything above one cannot be considered (i.e., 2). Therefore, the only option left is a) 0 and 1.

Answer:

a) 0 and 1

Step-by-step explanation:

the easiest way to think about this problem is using a number line to picture where the numbers are. I cant really do that easily on here but i will try my best to explain it with words.

If you think about where the numbers are on a number line you should see that -1/4 is slightly less than zero, which would put it to the left of zero.

Likewise, if you think about 3/2, which is equal to [tex]1\frac{1}{2}[/tex] it is slightly bigger than 1, which would put it to the right of 1 on a number line.

So if you think about the integers (which are numbers that can be positive or negative but do not involve decimals or fractions ex. -2, -1, 0, 1, 2 etc.) which are between those two numbers on the number line, the only integers are 0 and 1, which gives you your answer.

Answer:

41 degrees

Step-by-step explanation:

Here in this question , we are interested in calculating the value of angle x.

Firstly, we shall be needing a diagrammatic representation, please check attachment for this.

We are interested in calculating angle x, which represents the angle facing the opposite. The other third side that we have is referred to as the adjacent.

The trigonometric ratio to use here is thus called the tangent.

Mathematically the tangent of an angle = length of the opposite/length of the adjacent

The value 5.6 is our opposite since it faces the angle while the length 6.5 is the adjacent.

Thus;

tan x = 5.6/6.5

tan x = 0.8615

x = arc tan 0.8615

x = 40.75 degrees which is 41 degrees to the nearest degree

Answer:

41

Step-by-step explanation:

tan  −1  (  6.5 /  5.6  )  =  40.746 = 41

Answer: 87

Step-by-step explanation:

If it is the 165th person each day

7303/165 =  44.26 ( so 44 free admissions on Saturday)

7126/165 = 43.19 (so 43 free admissions on Sunday)

87 free admissions over the two days

If 165th person where it can carry over from day to day

(7303 + 7126)/165 = 87.49

87 free admissions over the two days

Same answer this time, but could be different in a diferent problem.

Answer:

The value of [tex]j[/tex]:

[tex]j = -56[/tex]

Step-by-step explanation:

Solve for [tex]j[/tex]:

[tex]\frac{j + 42}{-7} = 2[/tex]

-Multiply both sides by -7:

[tex]j + 42 = 2 ( -7)[/tex]

[tex]j + 42 = -14[/tex]

-Subtract both sides by 42:

[tex]j + 42 - 42 = -14 - 42[/tex]

[tex]j = -56[/tex]

So, therefore, [tex]x = -56[/tex] would be the final answer.

Answer:

j = -47

Step-by-step explanation:

I think you meant  j + 42 - 2 = -7

So what I would do is first find the two number we know which would be

42 - 2 = 40

So, then the equation comes down to j + 40 = -7

So,

j = -47

Because = -47 + 40 = -7

Have a good day. :)

Answer:

$60

Step-by-step explanation:

Firstly, you would divide $1,200 by 15, which is 80.

This gives you the cost for each television including the additional $20.

Then, you would do 80-20 = 60 to find the cost of the individual television without the warranty.

solution

or, 2 x + y = 5 y - 8 being opposite side of

parallelogram

or , 2x =5 y - y - 8

or, 2x = 4 y - 8

or, x = 4y - 8/2

or,. x = 2y- 4

therefore, 2x + y is equal to 5 y - 8 Being the opposite side of a parallelogram

now,

3y + 2 x is equal to 4x - 3 being opposite side of a parallelogram

or, 3y + 2 x-4x = -3

or,. 3y -2x = -3

Answer: A.

Step-by-step explanation:

yeet

Answer:

A.

Step-by-step explanation:

Because if you multiply out the top of the fraction to simplify it, it will equal zero. And zero divided by any number is equal to zero because no number fits into zero. So A. would be the best answer since you are multiplying an expression by zero on the top, and you can't get any number other then zero for the answer of the fraction. And 0 + 9.4 = 9.4.
