What is the line of reflection for the trapezoids?

Answer: The dot over a number signifies that it is a repeater which would go on for ever, as when we endeavor to describe 1/3 decimally as 0.33333 . . . . (etc) With a series of numbers we place the dot over the first and last, as with 0.97979797979 . . . (etc) The remarkable feature being that a proper fraction divided by 9s e.g. 46/99 is exactly equal to the numerator with the repeater sign followed by the decimal.

Answer:

slope is undefined

Step-by-step explanation:

Calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (1, 2) and (x₂, y₂ ) = (1, - 3)

m = [tex]\frac{-3-2}{1-1}[/tex] = [tex]\frac{-5}{0}[/tex]

Since division by zero is undefined then the slope of the line is undefined

Answer:

Your answer is x=3

Step-by-step explanation:

So  you have the equation 2x+5=11

First, subtract 5 from 5 and from 11.

Then you will cancel out the 5's.

After that, you should have "2x=6"

Now divide 2 from 2x and from 6.

Your answer is x=3

The equation that represents her savings is $450 = $120 + $30n.

The number of weeks that have passed since she opened her savings account is 11 weeks.

Total amount saved = amount initially deposited + (amount added weekly x number of weeks)

$450 = $120 + $30n

Where n = number of weeks

In order to determine the value of n, take the following steps:

Combine similar terms = $450 - $120 = 30n

$330 = 30n

Divide both sides by 30

n = 11 weeks

A straight line is an endless one-dimensional figure that has no width. It is a combination of endless points joined both sides of a point and has no curve.

Here, we have to points (1.5,0) and, (0,-3)

So, by using the formula of equation of straight line of two-point form, we get,

(y-y_1)/(x-x_1 )=(y_2-y_1)/(x_2-x_1 )

=>3x-1.5y=4.5

y=2x-3

Again,

Here, we have to points (-1.5,0) and, (0,-3)

So, by using the formula of equation of straight line of two-point form, we get,

(y-y_1)/(x-x_1 )=(y_2-y_1)/(x_2-x_1 )

=>3x+1.5y=-4.5

y=2x+3

Here, we have to points (1.5,0) and, (0,-3)

So, by using the formula of equation of straight line of two-point form, we get,

(y-y_1)/(x-x_1 )=(y_2-y_1)/(x_2-x_1 )

=>-3x+1.5y=4.5

y=-2x+3

Here, we have to points (-1.5,0) and, (0,3)

So, by using the formula of equation of straight line of two-point form, we get,

(y-y_1)/(x-x_1 )=(y_2-y_1)/(x_2-x_1 )

=>3x+1.5y=4.5

y=-2x-3

Hence, the required equations are,

1. y=2x-3

2. y=2x+3

3. y=-2x+3

Answer:

Part E is the pic

Part F is the triangle

sorry if it is kinda blurry

Part 6:

You've seen two methods for finding the area of AABC-using coordinate algebra (by hand) and using geometry software.

How are the two methods similar?

They both apply the fundamentals of triangle geometry in solving the area of a triangle using the formula for the area of triangle 1/2×base of triangle×height of the triangle.

How are they different?

Using coordinate algebra in finding the area of a triangle, you would have to measure coordinates(XY coordinates) of a triangle manually on the graph and find y coordinates based on x. If you used geometry software, it would get these coordinates automatically(based on your graph on the software) and calculate the area of the triangle using the formula.

Why might coordinate algebra be important in making and using geometry software?

A solid grasp of coordinate algebra allows you to understand how the geometry software works because it makes use of the same geometry fundamentals, making it easier for you to tweak and get the best value out of the software for your geometry calculations.

Answer:

about 50

Step-by-step explanation:

Ten teaspoons equal 50 milliliters using the conversion factor 1 tsp = 5 mL.

1 tsp = 5 mL

By multiplying 10 teaspoons by the conversion factor (10 tsp × 5 mL/1 tsp)

10 teaspoons × 5 mL/1 tsp = 50 milliliters

So, there are 50 milliliters in 10 teaspoons.

The conversion factor enables us to maintain the same quantity while converting between different units of measurement. It is an essential tool for performing precise conversions in a variety of disciplines including chemistry, medicine and cooking. For practical applications unit conversions must be understood in order to ensure accurate measurements and consistent outcomes across various measurement systems. Since milliliters are a more commonly used unit of measurement, the conversion in this instance enables us to express the volume of teaspoons in that unit.

1) The measure of ∠BOA is 60.16°.

2) the length of arc BAC is 14.68cm.

What is the formula for arc length?

Arc length = Central Angle(in radian) * Radius

So, length of arc AC = (45π/180) * 8

Arc AC = 2π

Arc AC = 6.28cm

So, length of arc BAC = arc AC+ arc AB

Arc BAC = 6.28 +8.4

Arc BAC = 14.68cm

∠BOA = length of Arc AB / Radius

∠BOA = 8.4/8 = 1.05 radian

∠BOA= 1.05 *(180/π)°

∠BOA=60.16°

Therefore, 1) The measure of ∠BOA is 60.16°.

2) the length of arc BAC is 14.68cm.

p=2l+2w

p=2(57)+2(47)

p=208 feet

The perimeter of rectangle is 208 ft.

The perimeter of a rectangle is the total length or distance of its boundary on all sides. The perimeter of a rectangle is a linear measure and is expressed in linear units of meters, feet, inches, or yards. Let us first understand the two main properties of a rectangle.

Therefore, the Perimeter of a rectangle = 2(l + w).

Given:

length = 47 ft

width = 57 ft

So, the perimeter of rectangle

= 2( l + w)

=2( 47 + 57)

= 2 x 104

= 208.

Hence, the perimeter of rectangle is 208 ft
