What is the equation for the line of symmetry in this figure?

Answer:

r = 22.629

Step-by-step explanation:

Using the Pythagorean theorem:

(35 + r)² = 53² + r²

1225 + 70r + r²  = 2809 + r²

subtract r² from each side of the equation:

1225 + 70r = 2809

subtract 1225 from each side:

70r = 1584

r = 22.629

the number of degree in the central angle

N is the degree of the central angle of the sector.

The sector angle is the angle subtended between two radii of circle to the center of Circle.

If the radius of the circle is 10 inches, and the central angle of the sector is 90 degrees, the area of the sector can be found as follows:

90/360 * (3.14 * 10^2).

Following the order of operations, the equation proceeds as follows:

1/4 * (3.14 * 100) = 1/4 * 314 = 78.5.

Thus, the area of the sector is 78.5 square inches.

The formula to find the area of a sector is A = N/360 x (pi x r^2).

A sector is a section of a circle. In the formula given, A is the area of the sector,

N is the degree of the central angle of the sector, pi is an irrational number that can be rounded to 3.14, and r is the length of the radius of the circle.

Hence,  N is the degree of the central angle of the sector.

Characteristics of a rectangle

One diagonal of a rectangle divides a rectangle into two right angled triangles. Thus, the length of the rectangle can be determined using the Pythagoras theorem

The Pythagoras theorem : a² + b² = c²

where a = length = ?

b = width = 7

c = diagonal = 11

7² + a² = 11²

49² + a² = 121²

a² = 121 - 49

a² = 72

calculate the square root of 72

a = 8.49 feet

We need to identify our independent variables and dependent variables.

The number of papers graded depend on the amount of time.

The amount of time is the independent variable

The papers graded depends us the dependent variable

Divide the independent variable by the dependent variable to find papers per minute

For Ms.Mitchell the papers per minute is

Given:

Output = 5 times input

To find:

The graph for the given statement.

Solution:

We know that, y-axis represents the output and x-axis represents the input.

Let y be the output and x be the input. Then the given statement can be written as

[tex]y=5x[/tex]

Here, the slope of the line is 5 because the value of [tex]m[/tex] is 5 on comparing the equation with [tex]y=mx+b[/tex].

It means the line is steeper because the vertical change is greater than the horizontal change.

Therefore, the correct option is A.

Answer:

q = 2√14

Step-by-step explanation:

To determine the value of q, apply the leg rule/geometric mean theorem, which is:

Hypotenuse/leg = leg/part

Hypotenuse = 10 + 4 = 14

Leg = q

Part = 4

Plug in the values into the equation:

14/q = q/4

Cross multiply

q*q = 14*4

q² = 56

q = √56

q = √(4*14)

q = 2√14

Answer:

q = 2√14

Answer:

27 tiles

Step-by-step explanation:

Here is the complete question :

Todd uses 21 white tiles and some black tiles to make a mosaic.the mosaic has a total area of 144 square centimeters. Each tile has an area of 3 square centimeters. How many black tiles did Todd use

Steps to take to determine the answer

Area of the white tile = area of each tile x total white tiles used

3 x 21 = 63cm²

144cm² - 63cm² = 81cm²

Number of black tiles used = 81cm² / 3cm² = 27 tiles

Answer: 19

Step-by-step explanation:

75 papers need to be marked

He grades 7 papers per hour

To find out how many paper he graded in 8 hours:

7 x 8

(7 is the number of papers graded in an hour)

(8 is the number of hours)

7 x 8 = 56

(56 is the number of papers he graded in 8 hours)

Now, there was a total of 75.

To find the remaining number of test sheets:

75 - 56

(75 is the total number of papers)

(56 is the number of papers graded)

75 - 56 = 19

Therefore, there are 19 papers remaining to grade.
