A go cart designer wants to build a Go Cart that measures 4 feet in height, 6 feet in width and 8 feet in length. He needs to construct a three - dimensional model of the Go Cart. Which measurements are appropriate for the scale model? a. 2 feet wide, 5 feet long and 2 feet high b. 3 feet wide, 4 feet long and 2 feet high c. 2.5 feet wide, 2 feet long, and 1.5 feet high d. 6 feet wide, 5 feet long and 3 feet high

Answers

Answer:

The correct answer is:

3 feet wide, 4 feet long, and 2 feet high (b)

Step-by-step explanation:

The appropriate scale for the model must be equivalent to the scale of the actual design. This means that the variation must be of the same magnitude in the length, height, and width.

Cart design = 4 feet high; 6 feet wide; 8 feet long

Cart design = 4H : 6W : 8L

where H, W, and L are height, width, and length respectively.

since the model of the Go Cart will be lesser than the actual Cart, let us divide the original cart design by the model designs given in the option, anyone that gives us a consistent variation is a right scale. This is done as follows:

a) Model design = 2H : 2W : 5L

dividing the original dimension by the model:

[tex]\frac{4H}{2H} : \frac{6W}{2W} : \frac{8L}{5L} \\= 2 : 3 : 1.6\\[/tex]

since the variations are not the same, this is the wrong model.

b) Model design = 2H : 3W : 4L

[tex]\frac{4H}{2H} : \frac{6W}{3W} : \frac{8L}{4L} \\= 2 : 2 : 2\\[/tex]

variation is the same across the three dimensions, hence this is the right model.

You can go ahead to use the same principle to do the third model, to see what you will get.

What is skewness?

Skewness is a metric for the asymmetry or distortion of symmetrical distribution in a set of data. When data points on a bell curve are not evenly distributed to the left and right sides of the median, this is known as skewness. The bell curve is referred described as being skewed if it is tilted to the left or right.

Prove that quadrilateral Q(1, 2), U(2, 5), A(5, 7) and D(4, 4) is a parallelogram by using slopes.

Slope of QU =

Slope of AD =

Slope of UA =

Slope of QD =

Which sides are parallel (give the letters) A) sides QU and AD B) sides QU and UA C) sides UA and QD D) sides AD and QD

Answers

Answer:

[tex]m = 3[/tex] ---- Slopes of QU and AD

[tex]m =\frac{2}{3}[/tex] ---- Slopes of UA and QD

Sides QU and AD have the same slope

Sides UA and QD have the same slope

Step-by-step explanation:

Given

[tex]Q = (1, 2)[/tex]

[tex]U = (2, 5)[/tex]

[tex]A = (5, 7)[/tex]

[tex]D = (4, 4)[/tex]

Solving (a): Slope of QU

[tex]Q = (x_1,y_1)= (1, 2)[/tex]

[tex]U = (x_2,y_2)= (2, 5)[/tex]

Slope, m is calculated as:

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

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

[tex]m =\frac{3}{1}[/tex]

[tex]m = 3[/tex]

Slope of AD

[tex]A =(x_1,y_1) = (5, 7)[/tex]

[tex]D = (x_2,y_2) = (4, 4)[/tex]

Slope, m is calculated as:

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

[tex]m =\frac{4-7}{4-5}[/tex]

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

[tex]m = 3[/tex]

Slope of UA

[tex]A =(x_1,y_1) = (5, 7)[/tex]

[tex]U = (x_2,y_2)= (2, 5)[/tex]

Slope, m is calculated as:

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

[tex]m =\frac{5-7}{2-5}[/tex]

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

[tex]m =\frac{2}{3}[/tex]

Slope of QD

[tex]Q = (x_1,y_1)= (1, 2)[/tex]

[tex]D = (x_2,y_2) = (4, 4)[/tex]

Slope, m is calculated as:

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

[tex]m =\frac{4-2}{4-1}[/tex]

[tex]m =\frac{2}{3}[/tex]

Solving (b): Parallel Sides

Two sides are said to be parallel if they have the same slope.

The slope were calculated in (a) above and from there, we have the following observations

1. QU and AD have the same slope of 3

2. UA and QD have the same slope of 2/3

The amount a hardware store pays for buying nylon rope is represented by the equation y = 0.08x, where 'y' is the price it pays for 'x' feet of rope. The amount the hardware store charges for selling the rope is represented by the graph. Part A What does the slope of the graph show about the hardware store's selling price for the rope?

Answers

Answer:

0.025 $/in.

The store bought 300 ft of rope.

1 ft = 12 in.

300 ft * 12 in./ft = 3600 in.

The store bought 3600 inches of rope.

The store sells 40 inches of rope for $1.60. We can find the selling unit price of rope in dollars per inch.

($1.60)/(40 in.) = $0.04/in.

The store sells the rope at a price of $0.04 per inch.

The store sold all the rope at $0.04/in.

3600 in. * $0.04/in. = $144

The store sold all the rope for $144.

The profit was $54 for selling ll the rope.

$144 - $54 = $90

The bought the rope for $90.

The cost is dollars per inch is

($90)/(3600 in.) = 0.025 $/in.

Step-by-step explanation:

The slope tells for every one-foot increase in the amount of rope sold, the hardware store increases the selling price by $0.08.

The slope of the graph represents the rate of change between the hardware store's selling price (y-axis) and the quantity of nylon rope sold (x-axis).

In this case, the slope is given as 0.08.

Interpreting the slope:

A slope of 0.08 means that for each additional foot of nylon rope the hardware store sells (x increases by 1), the selling price (y) increases by $0.08.

This indicates a linear relationship between the quantity of rope sold and the selling price.

In other words, for every one-foot increase in the amount of rope sold, the hardware store increases the selling price by $0.08.

The points (-6,8) and (0,8) are coordinate points, and the distance between the points (-6,8) and (0,8) is 6 units

The distance between the two points

The points are given as:

B = (0,8)

The distance between the points is calculated using:

[tex]d= \sqrt{(x_2 - x_1)^2 + (y_2 -y_1)^2}[/tex]

So, we have:

At 1 the time, the hundreds of millions who watched this historic event likely thought it marked the beginningof a bold new kind of exploration. Perhaps they thought they would soon hear more messages from outer space. Maybe they envisioned that by the turn of the century someone would walk on the surface of Mars. Now, though, more than 40 years later, its robotsnot astronautswho are making most of the voyages beyond Earths atmosphere. Robotic space exploration does have some advantages. However, there are many reasons why we should make sending more people into space a priority.-Beyond the Program-The capabilities of the space probes and rovers we now use would have been the stuff of science fiction 2 just a few short decades ago. Like any other machines, though, they have one major weakness. Theycan do only what they are programmed to do. They cannot make a distinction between unusual and expected observations. They cannot reason. They cannot think. A human scientist who identified a curious specimen on Mars would likely concentrate on finding out everything possible about it. The unthinking robot would probably treat it as just another sample.-Efforts Yield Results-One of the arguments in favor of using robots to explore space is that machines can go places humans cannot. This may be true, but lets consider the other side. Maybe the reason astronauts are not able to go to these places yet is that we arent putting enough effort into figuring out how to meet their complex needs during prolonged space missions. Humans have proven time and again that they are able to solve problems that may have seemed impossible at first. There is no reason to assume that the challenge of sending people to Mars, Jupiter, or Neptune and getting them back home safely would be any different.-Costs and Benefits-Humans, as living things, have many needs that robots do not. Giving astronauts what they require to stay 4 healthy in space naturally makes these kinds of missions more expensive than ones that use robots. Its vital to weigh these increased costs against the benefits. If sending one human crew to Venus could advance our knowledge of the universe as much as three robotic space missions could, even a much higher cost would be justified.Keeping the Dream Alive It is said that the idea of traveling into space captures the imagination. For most, though, its not an image 5 of a small vehicle rolling across the surface of Mars that inspires awe and wonder. Its the notion thatone daypeople from Earth will explore distant worlds that are literally millions of miles away from our home planet. 13) Why does the author MOST LIKELY use the word stretches in the firstsentence of the second paragraph of the passage?A)to emphasize the vast size of the desertB)to compare it to the desert in AntarcticaC)to reveal that the desert is increasing in sizeD)to show that the desert is in the northern part ofAfrica Ten students in your class put their names on slips of paper inside a box.
