which dimconstraint option allows you to create a dimensional constraint that has extension lines perpendicular to an angled surface?

Step-by-step explanation:

as per the midsegment theorem

the lines connecting the half-points are half as long as the corresponding parallel side lines of the main triangle, ABC.

EF is half as long as AB = 4/2 = 2

DE is half as long as AC = 6/2 = 3

DF is half as long as BC = 4/2 = 2

so, the perimeter of DEF is

2 + 3 + 2 = 7

Original shape will contract when scale factor is less than 1 , expand when scale factor is greater than 1 and it doesn't change when scale factor is 1

A scale factor is a number that can be used to change the size of any geometrical figure or shape in relation to its original size. It is the ratio of the sizes of the original and dilated figures.

It is denoted by "k"

The magnitude of the scale factor is taken into account, and it cannot be zero. The scale factor has the ability to either increase or decrease the size of an object.

The basic formula for calculating the scale factor of a dilated figure is as follows:

Scale = dimension of preimage / dimension of image

According to the question,

(a) If scale factor is less than 1 , k < 1 then the original shape will contract means It's size will decrease

(b) If scale factor is greater than 1 , then image will enlarge and it would expand

(c) If scale factor is equal to 1 , then No change in shape nor in size

The required volume of the right circular cone is 135.83409in³.

A right circular cone is one whose axis is the line between the vertex and the circular base's midway.

In other words, a right angle is formed when the center point of the circular base and the cone's peak are united.

So, the right circular cone volume formula:

V=1/3hπr²

Diameter = 8.8 in

Radius = 8.8/2 = 4.4 in
Now, calculate the volume as follows:

V = 1/3hπr²

V = 1/3(6.7)π(4.4)²

V = 135.83409 in³

Answer:It was not until the eighteenth century that mathematician Leonard Euler (1707-1783) discovered a relationship between the three classical triangle centers.

Step-by-step explanation:

To write an area, you need to know the shape and the measurements of the sides.

For example, if you have a square, you can calculate its area with the formula A = s², where A is the area and s is the length of a side.

If the side is 10 cm, then the area would be written as A = 10² = 100 cm².

1. Identify the shape of the area you are trying to calculate.

2. Calculate the measurements of the sides.

3. Use the appropriate formula to calculate the area. For example, for a square, use the formula A = s², where A is the area and s is the length of a side.

4. Plug in the measurements and calculate the area.

5. Write the area using the correct unit of measurement. For example, if the side was 10 cm, the area would be written as A = 10² = 100 cm².

Make y the subject in the equation

So, we have

y = x/3 - 4

The equation of a line can be represented as

y = mx + c

Where

slope = m

By comparing the equations, we have:

m = 1/3

The slopes of parallel lines are equal

This means that the slope of the other line is 1/3

i.e. m = 1/3

Recall that:

The equation of a line can be represented as

y = mx + c

Where

Simple interest is used to determine the amount of interest that will be charged on a sum of money at a specific rate and for a specific amount of time. The principal amount in simple interest does not change, in contrast to compound interest, which adds the interest from the principal of preceding years to determine the interest of the following year.

Here,

Given:

The amount of electrician account earned is 1680

thus total amount is = 1680 + x

where x is the principal amount

Interest rate = 7.5%

and total years = 4 years

Using formula

[tex]\frac{P*R*T}{100}[/tex]= Simple interest

=> 1680 = x*7.5*4/100

=>1680 =x * 30/100

The annual return of the investment is 31.1%.

Given that, person has purchased a single-family home that you intend to rent for $850 per month.

A return, also known as a financial return, in its simplest terms, is the money made or lost on an investment over some period of time.

First find the amount earned per year:

= 850 x 12

= $10,200

The yearly expenses would be:

= (390 x 12) + (60 x 12) + (340 x 2) + 500 + (100 x 12)

= 4,680 + 720 + 680 + 500 + 1,200

The annual ROI is:

= (10,200 - 7,780) / 10,200 x 100%

The percentage of income that a person or corporation must pay or withhold as taxes is known as the effective tax rate. The effective tax rate is 10.15%. Here option A is the correct answer.

The term effective tax rate refers to the average tax rate that an individual pays on both earned and unearned income, such as stock dividends. According to the progressive tax model, when income rises, the tax rate also rises, putting persons in a higher tax bracket.

Here, the presented data shows that the marginal tax rate is 22% for taxable income in the $40,526 to $86,375 income range.

Effective tax rate = total taxes owed/taxable income × 100.
