100 POINTS!!! Orthographic projection and isometric projection are two ways to show three-dimensional objects in a two-dimensional space, such as on a piece of paper or a computer screen. Each method gives a different perspective. Do some research and then compare and contrast the two methods for displaying three-dimensional shapes. Then try your hand at creating both types of projections for a simple geometric shape using paper, pencil, and a ruler.

In your opinion, what are the pros and cons of each projection? What are the limitations? In which circumstances, environments, or occupations is one type of projection likely preferred over the other? Describe any special tools that might be needed to create the projection. Which projection is easiest for you to interpret visually? Why?

Answers

Example 1:

The pros of Orthographic is that they can show hidden details and all of the connecting parts, they can be annotated to display material and finishes. The pros of Isometric projection is that they dont need many views and it gives accuracy, cons are is created a unorginized apperance by the lack of foreshortening, I would choose Isometric projection because it shows the size of the figure.

Example 2:

Orthographic projection is a good option for showing lots of detail and small things. The limitation is that with all of that detail, they can become quite messy and hard to understand to someone new to them. However, that is one of the pros of Isometric projection. It gives easy detail and is just as good as an Orthographic. Personally, I find Isometric projections easier to interpret.

Answer:

x = 5 / 3 = 1.667

Step-by-step explanation:

8*x+10-5*x-(15)=0

Solve : 3x-5 = 0

Add 5 to both sides of the equation :

3x = 5

Divide both sides of the equation by 3:

x = 5/3 = 1.667

x = 5/3 = 1.667

Pam bought 20 pieces of fruit for her class.
o   Each piece of fruit was either an apple or an orange.
o   She spent $1.25 on each apple.
o   She spent $0.95 on each orange.
o   Pam spent a total of $22.60.
Write a system of equations that can be used to find the number of apples Pam bought. Make sure to define your variables.

Choose the correct define variables and the correct system of equations

Answers

Answer:

Step-by-step explanation:

Let O=number of oranges and A=number of apples.

O+A=20

O=20-A

1.25A+0.95O=22.60, using O found above makes this become

1.25A+0.95(20-A)=22.60

1.25A+19-0.95A=22.60

0.3A+19=22.60

0.3A=3.6

A=12, since O=20-A

O=20-12

O=8

So she bought 8 oranges and 12 apples. The question really only asks for the number of apples bought.

12 apples were bought.

Answer:

1.25x+0.95y=22.60

x is apples y is oranges

Step-by-step explanation:

20 - 12 = 8

1.25(12) + 0.95(8) = 22.60

1.25 · 12 = $15

0.95 · 8 = $7.60

15.00 + 7.60 = $22.60

A ranch hand herded his cattle to some grazing land. Then he began riding back to the ranch,
which is due west, at 7 miles per hour. Simultaneously, the cows began moving away from
him, too, headed due east at 3 miles per hour. How long did it take for the herd and the
ranch hand to be 2 miles apart? (Please help me !!)

Answers

Answer:

1/5 hr or 12 min

Step-by-step explanation:

We are going to use the formula D = RT

Let t = the time for them to be 2 mi. apart

Then 7t = the distance the ranch hand traveled

and 3t = the distance the cows traveled

Since they traveled in opposite directions, the sum of their distances will give us how far they are apart.

So, 7t + 3t = 2

10t = 2

t = 2/10 = 1/5 hr. = 12 min.

Step-by-step explanation:

Given

[tex]Initial = 6.5kg[/tex]

[tex]Final = 3.9kg[/tex]

Required

Determine the percentage change --- Missing from the question

This is calculated as

[tex]\%Change = \frac{Final - Initial}{Initial} * 100\%[/tex]

[tex]\%Change = \frac{3.9kg - 6.5kg}{6.5kg} * 100\%[/tex]

[tex]\%Change = \frac{-2.6kg}{6.5kg} * 100\%[/tex]

[tex]\%Change = \frac{-260}{6.5}\%[/tex]

If f(1)=6 and f(n)=f(n-1)+2 then find the value of f(6)

Answers

Answer:

Step-by-step explanation:

Answer:

f(6) = 16

Step-by-step explanation:

In the next steps we use this formula : f(n)=f(n-1)+2

Since f(1)=6 then f(2)=f(2-1)+2 = f(1)+2 = 6+2 = 8

f(2)=8 then f(3)=f(3-1)+2 = f(2)+2 = 8+2 = 10

f(3)=10 then f(4)=f(4-1)+2 = f(3)+2 = 10+2 = 12

f(4)=12 then f(5)=f(5-1)+2 = f(4)+2 = 12+2 = 14

f(5)=14 then f(6)=f(5-1)+2 = f(4)+2 = 14+2 = 16.

The equation of the line is y=-1/2x-3.5

Step-by-step explanation:

Given the two points on the line, (1, -4) and (3, -5), find the slope of the line with the equation [tex]m=\frac{y2-x2}{y1-x1}[/tex].

[tex]m=\frac{-5-(-4)}{3-1} =\frac{-5+4}{3-1} =\frac{-1}{2}[/tex]

After you find the slope of the line, substitute x and y with either point given to you. For me, I'll use point (1, -4) to solve for the y-intercept.

[tex]-4=\frac{-1}{2} (1)+b[/tex]

[tex]\frac{1}{2} -4=\frac{-1}{2} +\frac{1}{2} +b[/tex] add both sides by 1/2 so that b is alone

[tex]\frac{-7}{2} =b[/tex]

You can rewrite -7/2 as -3.5.

Answers

Answer:

m∠T = 54°

Step-by-step explanation:

The measure of a straight line is 180°. (Linear angles theorem)

So, m∠WMT + 117° = 180°

m∠WMT = 180 - 117 = 63°

The base angles in an isoceles triangle are equal in measure (base angle theorem)

So,

m∠MWT = m∠WMT

m∠MWT = 63°

The sum of angles in a triangle is 180°. (Sum of angles in a triangle theorem) So,

m∠MWT + m∠WTM + m∠WMT = 180°

Substitute the measures we already found.

63 + m∠WTM + 63 = 180

Simplify.

126 + m∠WTM = 180

m∠WTM = 54°

m∠T = 54°

I hope this helps! Feel free to ask any questions!

Answer:

54°

Step-by-step explanation:

First calculate Angle WMT as: 180° - 117° = 63°

And note that Angle WMT = Angle MWT = 63°

Therefore, Angle T = 180° - 63° - 63°

Angle T = 54°

A high school drama department sold 238 tickets for their performance.
o   An adult ticket cost $6.75.
o   A student ticket cost $3.50.
o   The high school drama department collected $1,252.25 in ticket sales.
How many student tickets were sold?

Answers

Let x = number of student tickets
Ley y = number of nonstudent tickets

then we know that the total number of tickets is 537

so

x + y = 537

if we multiply the cost of a ticket by the number of tickets we can also get the total $

3.2x + 5.9y = 2185.5

now we have two equations and two unknowns and we can find the value for these unknowns

lets use substitution

x + y = 537 that means that x = 537-y

substitute this value in the second equation

3.2(537-y) + 5.9y = 2185.5

1718.4 - 3.2y +5.9y = 2185.5

1718.4 + 2.7y = 2185.5

2.7y = 2185.5 - 1718.4

2.7y = 467.1

y = 173

x + y =537

x + 173 = 537

x = 364

Answer:

$6.75 + $3.50 = X

X ÷ $1,252.25

Step-by-step explanation:

$6.75 + $3.50 = $10.25

$10.25 ÷ $1,252.25 = 0.00818526652
