The length of an arc between two consecutive spokes is 5π/8 in.

The length of an arc L = rФ where

So, L = rФ

L = r × 2π/n

L = 2πr/n

Substituting the values of the variables into the equation, we have

L = 2πr/n

L = 2π × 2.5 in/8

L = 5π/8 in

So, the length of an arc between two consecutive spokes is 5π/8 in.

Answer:company b

Step-by-step explanation:

it would cost $75 to hire company b and $90 to hire company a.

Answer:

See below.

Step-by-step explanation:

We can represent Imani's weekly allowance with the variable a. The equation you can write is:

1/2a+4=12

2(1/2a+4)=2(12)

a+8=24

a=16

The Imani's weekly allowance value is $16.

To solve this problem using a two-step equation,  follow these steps:

Step 1: Let's represent Imani's weekly allowance with the variable "x."

Step 2: We know that Imani spent half of her allowance playing mini-golf, so the amount she spent is (1/2) × x. Additionally, she earned $4 by washing the car. Therefore, the equation becomes:

x - (1/2) × x + 4 = 12

To solve this equation, we need to combine like terms and isolate the variable "x":

(1/2) ×x = 12 - 4

(1/2) × x = 8

Next multiply both sides of the equation by 2 to eliminate the fraction:

2 × ((1/2) × x) = 2 × 8

x = 16

Hi there !

$20 ........ 100%

$12 ..............x %

x = 12×100/20

Answer: 11.73 seconds

Step-by-step explanation:

To solve the question, we have to add the time used by Giselle, Sarah and Aliyah and then subtract from 41.37 seconds to determine the time used by Kelly. This will be:

= 41.37 - (9.36 + 9.71 + 10.57)

= 41.37 - 29.64

= 11.73 seconds

Kelly used 11.73 seconds

All you have to do to figure this out is divide your 50 invitations by twenty stamps because there is 20 stamps in one booklet. 50 divided by 20=2.5

Answer:

3 books

Step-by-step explanation:

Assuming that you cannot buy a partial book of stamps, you would have to buy a surplus in order to obtain (at least) 50 stamps. That is because 50 is not a multiple of 20.

In theory you would need 2.5 books of stamps, but that half-book should be counted and rounded up to three. You wouldn't have sufficient stamps if you buy only 2 books.

Answer:

18.54

Step-by-step explanation:

15.55 X 7% = 1.0885

15.55 + 1.0885 = 16.6385 X 18% = 2.99493

15.55 + 2.99493 =18.54493

These are the laws of exponent.

Solution:

We know that:

Area of circle = πr² = 16π

Let's undo this equation by dividing π both sides. Then, take a square root to find the radius.

Now, let's find the circumference by substituting the radius in the circumference formula.

Since the question says to leave the circumference in terms of π, 8π meters is the circumference of the circle.

Thus, the circumference is 8π meters

==================================================

Explanation

The diagonals of a rhombus are always perpendicular.

This leads to triangle ECB being a right triangle. The 90 degree angle at point E.

The other acute angles add to 90

C+B = 90

(5a+4) + (8a-5) = 90

13a-1 = 90

13a = 90+1

13a = 91

a = 91/13

a = 7

This value then leads to:

Note how 39+51 = 90 to confirm that C+B = 90 is correct. This confirms the correct 'a' value and final answer.

Answer:

[tex]\displaystyle y = x^2 + 6x + 12[/tex]

Step-by-step explanation:

To begin with, to define the stretch factour [tex]\displaystyle [A],[/tex]from the standard quadratic equation of [tex]\displaystyle y = Ax^2 + Bx + C,[/tex]find the rate of change between the vertex of [tex]\displaystyle [-3, 3][/tex] and either [tex]\displaystyle [-4, 4][/tex]or [tex]\displaystyle [-2, 4].[/tex]It really does not matter which ordered pair you choose to pair with the vertex because one result will be negative, and the other result will be positive, so it is as though you are taking the absolute value of the rate of change, but not entirely. Anyhow, let us get to wourk:

[tex]\displaystyle \frac{-y_1 + y_2}{-x_1 + x_2} = m \\ \\ \frac{-4 + 3}{2 - 3} \hookrightarrow \frac{-1}{-1} \\ \\ 1 = m[/tex]

OR

[tex]\displaystyle \frac{-y_1 + y_2}{-x_1 + x_2} = m \\ \\ \frac{-4 + 3}{4 - 3} \hookrightarrow \frac{-1}{1} \\ \\ -1 = m[/tex]

So, both oppocite rate of changes tell you that the stretch factour of this quadratic function is [tex]\displaystyle 1,[/tex]ESPECIALLY sinse the graph opens upward.

Now, to determine the quadratic equation for this graph, you need to write this in vertex form first. Remember to base the equation off the vertex:

[tex]\displaystyle y = A[x - h]^2 + k \\ \\ y = [x + 3]^2 + 3[/tex]

So, −C gives you the OPPOCITE TERMS OF WHAT THEY REALLY ARE, and sinse the vertex [tex]\displaystyle [(h, k)][/tex]is at [tex]\displaystyle [-3, 3],[/tex]there MUST BE a plus sign inside those brackets. Anyway, let us continue:

[tex]\displaystyle y = [x + 3]^2 + 3 \hookrightarrow y = x^2 + 6x + 9 + 3 \\ \\ \boxed{y = x^2 + 6x + 12}[/tex]

You now have your quadratic equation.
