Adding two right angles, each being 90 degrees, always results in a straight angle, which is 180 degrees, so this is always true.

The sum of two right angles always results in a straight angle. This can be justified with a basic understanding of angles in a flat plane. A right angle is 90 degrees and a straight angle is 180 degrees. So, if you add two right angles together (90 + 90), you get 180, which is the measure of a straight angle. Hence, this is always true, regardless of the vectors or other elements you are working with. It's also important to note that in broader geometric terms, this statement is also always true: two angles that add up to form a straight line (180 degrees) are referred to as supplementary angles.

Step-by-step explanation:

For an hour of assistance if a student charged $10.25 than total number hours a student need to work to earn $8,425 is 821.95 hours and this can be determine by the help of unitary method.

Given :

Charge for 1 hour assistance = $10.25

Total earning through assistance = $8425

In this problem unitary method can be use to determine the total number of hours need to work to earn $8425. In unitary method, single unit value is determine first to evaluate the necessary value by multiplying the single unit value.

For an hour of assistance if a student charged $10.25 than total number hours a student need to work to earn $8,425 can be:

[tex]= \dfrac{8425}{10.25} \times 1[/tex]

= 821.95 hours

So a student need to work a total of 821.95 hours to earn $8425.

Final answer:

The actual length of the organism is 0.32 millimeters, which is obtained by dividing the photograph length (32 mm) by the magnification factor (100).

Explanation:

To determine the actual length of the one-celled organism when the photograph has been enlarged by a factor of 100, we use the formula:

Actual length = Photograph length ÷ Magnification factor

Substituting the given values:

Actual length = 32 mm ÷ 100

Actual length = 0.32 mm

This calculation shows that the actual length of the organism is 0.32 millimeters, which is equivalent to 320 micrometers (320 µm). It's interesting to note that this is well within the size range for many microorganisms, which may require magnification to be seen clearly, such as with a microscope.

The length of the apothem of a regular polygon that has a radius of 10 inches would be 9 inches .

The apothem of a regular polygon is defined as a line segment from the center to the midpoint of one of its sides.

It is Given that the hexagon has a radius of 10 inches and the length of the radius is equal to the length of each side of the hexagon.

The apothem AB divides the side of the hexagon into two equal parts of 5 Inches.

Using Pythagoras Theorem

[tex]10^2 = 5^2 + AB^2\\AB^2 = 10^2 -5^2\\AB^2 = 100 - 25\\AB^2 = 75\\AB = \sqrt{75}[/tex]

AB = 8.66

So, rounded up, we get the apothem closest to D that is 9 in.

Answer with explanation:

→Two lines in three dimensional plane are said to be Skew if they are neither parallel nor Intersecting.

→Skew lines can be drawn in three dimensional plane only.

→Drawn two skew lines in a Plane , and then drawn another line in a plane and found that , they are skew.

⇒Yes, it is possible to draw three lines in two planes such that all three lines are skew.

Skew lines are non-coplanar lines that are not parallel, and they do not intersect.

The question does not state the type of plane. So, I will answer this question in 2 ways.

(a) 2D plane

Lines in 2D planes can only be drawn in a flat direction.

This means that, when three lines are drawn in the two planes, one of the following would happen.

See attachment for illustration

So, 3 lines in a 2D plane cannot be skewed lines

(b) 3D plane

Lines in 3D planes can only be drawn in several directions.

The above statement imply that:

Several lines can be drawn where none of the lines would be parallel and none of the lines would intersect.

This means that, when three lines are drawn in the two planes, one of the following would happen.

The third highlight means that:

It is possible to have skew lines in a 3D plane

Answer:

The total cost of the car be $35162.5 .

Step-by-step explanation:

As given

John Gray bought a basic car for $32,750.00, with options that cost $375.00.

Cost of the car = Car cost + Option cost

                          =  $32750 + $375

                          = $33125

As given

There's a 6% sales tax in his state .

6% is written in the decimal form.

[tex]= \frac{6}{100}[/tex]

= 0.06

Sales tax price = 0.06 × 33125

                        = $ 1987.5

As given

A combined $50.00 license and registration fee.

Than

Total cost of the car  =   Cost of the car  + Sales tax price +  license and registration fee.

                                  =  $33125 + $ 1987.5 + $ 50

                                 = $35162.5

Therefore the total cost of the car be $35162.5 .

The side length of the resulting octagon is 2√2.

A stop sign is a regular octagon formed by cutting triangles off the corners of a square. To find the side length of the resulting octagon, we can use the Pythagorean theorem. Since the square has sides of length √2, its diagonal can be found by multiplying its side length by √2. This gives us a diagonal length of 2√2. The diagonal of each triangle cut off the corners of the square will be the side length of the resulting octagon. So, the side length of the octagon is 2√2.
