My favorite thing at the space art exhibit was a room full of robots made from nuts, bolts, and car parts. Blinking, talking. They posed the robots in front of paintings from of all different kinds of real and imaginary planet landscapes such as Jupiter and Mars. Some of the robots were fierce, and some wore makeup. I also liked the “space city” that some artist constructed by cutting small holes in of all kinds of colorful tents and lighting them from within.

Melissa will rent a car for the weekend. She can choose one or two plans. The first plant has no initial fee but costs $.80 per mile driven. That’s like a plan has an initial fee of $75 in cost an additional $.38 per mile driven. How many miles with Melissa need to drive for two plants to cost the same? NEED HELP ASAP PLEASE

[ad_1]

If you equal both of the PLANS you will get
$.80x=$75+$.38x
then you subtract .38x on both sides and get
$.42x=$75
once thats done you will divide .42 on both sides leaving the variable x by itself…
and then x=178.57miles
but to break even it would be 179 miles for both of the plans to cost the same

Read the following excerpt from Leslie Marmon Silko’s story “The Man to Send Rain Clouds.” They turned off the highway onto the sandy pueblo road. Not long after they passed the store and post office they saw Father Paul’s car coming toward them. When he recognized their faces he slowed his car and waved for them to stop. The young priest rolled down the car window. “Did you find old Teofilo?” he asked loudly. Leon stopped the truck. “Good morning, Father. We were just out to the sheep camp. Everything is O.K. now.” “Thank God for that. Teofilo is a very old man. You really shouldn’t allow him to stay at the sheep camp alone.” “No, he won’t do that any more now.” What does this dialogue reveal about the priest’s standing within the community? He is a trusted leader of the tribe. He is considered to be an outsider. He is a spiritual guide to the people. He is disliked by most of the people.

[ad_1]

Answer: The right answer is the B: He is considered to be an outsider.

Explanation: Leon and his brother-in-law, Ken, had found Teofilo’s corpse under a tree. However, when Father Paul, a Franciscan priest, asked them if they had found him, Leon did not mention that Teofilo had died. He did not openly lie to the priest, but he avoided mentioning Teofilo’s death to him. This shows that Father Paul was not considered part of the tribe, but an outsider that was trying to “impose” his faith and his religious practices on a community that already had its own.

For which purpose and audience would an email be the most effective type of document? A. Applying for a job at the shoe store at the mall B. Convincing your parents to let you borrow the car C. Inquiring about volunteer opportunities for a local political candidate D. Persuading the senior class to elect you prom queen

[ad_1]

Answer:

C. Inquiring about volunteer opportunities for a local political candidate

Explanation:

This is the best choice because there may be many different positions available as a volunteer for a local political candidate. Also, an application to be a volunteer and other information can be easily sent through email. Other options are not good choices. A job application should not be emailed because it is too informal. Convincing your parents to let you borrow the car should be a face to face conversation. Persuading the senior class to elect you prom queen is usually done in a speech and with other campaign advertising.

It takes 31 employees and $7500 to build a car, and it takes 19 employees and $4300 to build a motorcycle. Genghis Motors wants to spend more than $84000 to build cars and motorbikes using at most 706 employees. Let C denote the number of cars they build and M the number of motorbikes they build. Write an inequality that represents the condition based on the number of employees.Write an inequality that represents the condition based on the number of dollars.

[ad_1]

we know it takes 31 workers to do a car, and 19 to do a motorcycle… so hmmm to make “c” cars, it will then take 31*c workers, or 31c

to make “m” motorcycles, it will then take 19*c or 19c employees

whatever those amounts of workers needed to make both, must be an amount  that is 706 or less, thus    

31c + 19m ⩽ 706

now…. it takes $7500 to make a car and thus to make “c” cars it will then take 7500* c or 7500c

it takes $4300 for a motorbike, thus to make “m” motorbikes, it will then take 4300*m, or 4300m

whatever those dollar amounts are, must be 84000 or more, since Genghis Motors wants to spend that OR more

7500c + 4300m > 84000

Answer:

Option C – BD=76 cm

Step-by-step explanation:

Given : You are designing a diamond-shaped kite. you know that AD = 44.8 cm, DC = 72 cm, and AC = 84.8 cm.

To find : How long BD should it be?

Solution :

First we draw a rough diagram.

The given sides were AD = 44.8 cm, DC = 72 cm and AC = 84.8 cm.

According to properties of kite

Two disjoint pairs of consecutive sides are congruent.

So, AD=AB=44.8 cm

DC=BC=72 cm

The diagonals are perpendicular.

So, AC ⊥ BD

Let O be the point where diagonal intersect let let the partition be x and y.

AC= AO+OC

AC=  x+y=84.8 …….[1]

Perpendicular bisect the diagonal BD into equal parts let it be z.

BD=BO+OD

BD=z+z

Applying Pythagorean theorem in ΔAOD

where H=AD=44.8 ,P= AO=x , B=OD=z

H^2=P^2+B^2

(44.8)^2=x^2+z^2  ………[2]

Applying Pythagorean theorem in ΔCOD

where H=DC=72 ,P= OC=y , B=OD=z

H^2=P^2+B^2

(72)^2=y^2+z^2 …………[3]

Subtract [2] and [3]

(72)^2-(44.8)^2=y^2+z^2-x^2-z^2

5184-2007.04=(x+y)(x-y)

3176.96=(84.8)(x-y)

37.464=x-y ……….[4]

Add equation [1] and [4], to get values of x and y

x+y+x-y=84.8+37.464

2x=122.264

x=61.132

Substitute x in [1]

x+y=84.8

61.132+y=84.8

y=23.668

Substitute value of x in equation [2], to get z

(44.8)^2=x^2+z^2

(44.8)^2=(23.668)^2+z^2

2007.04-560.174224=z^2

z=sqrt{1446.865776}

z=38.06

We know, BD=z+z

BD= 38.06+38.06

BD= 76.12

Nearest to whole number BD=76 cm

Therefore, Option c – BD=76 cm is correct.

A car is a vehicle with four wheels. Rewrite the statement as a true conditional with a converse that is false. Write a similar true conditional with a converse that is true

[ad_1]

The basis to respond this question are:

1) Perpedicular lines form a 90° angle between them.

2) The product of the slopes of two any perpendicular lines is – 1.

So, from that basic knowledge you can analyze each option:

a.Lines s and t have slopes that are opposite reciprocals.

TRUE. Tha comes the number 2 basic condition for the perpendicular lines.

slope_1 * slope_2 = – 1 => slope_1 = – 1 / slope_2, which is what opposite reciprocals means.

b.Lines s and t have the same slope.

FALSE. We have already stated the the slopes are opposite reciprocals.

c.The product of the slopes of s and t is equal to -1

TRUE: that is one of the basic statements that you need to know and handle.

d.The lines have the same steepness.

FALSE: the slope is a measure of steepness, so they have different steepness.

e.The lines have different y intercepts.

FALSE: the y intercepts may be equal or different. For example y = x + 2 and y = -x + 2 are perpendicular and both have the same y intercept, 2.

f.The lines never intersect.

FALSE: perpendicular lines always intersept (in a 90° angle).

g.The intersection of s and t forms right angle.

TRUE: right angle = 90°.

h.If the slope of s is 6, the slope of t is -6

FALSE. – 6 is not the opposite reciprocal of 6. The opposite reciprocal of 6 is – 1/6.

So, the right choices are a, c and g.

A car in dynamic equilibrium is acted upon by the following forces: force due to gravity= -9000 newtons Force due to friction = -250 newtons Forward force exerted by engine = 250 newtons. What is the value of the force exerted by the ground on the car?

[ad_1]

The gravitational force Fg between two objects is given by the equation:

Fg=(G*m₁*m₂)/r₂, where G=6.67*10^-11 m³ kg⁻¹ s⁻² is the gravitational constant, m₁ and m₂ are the masses of the two bodies and r is the distance between those bodies. 

Due to the gravitational attraction the pencil and the eraser will attract if we there is no friction on the surface. 

m₁=10 g=0.01 kg is the mass of the pencil
m₂=20 g=0.02 kg is the mass of the eraser
r=2.5 cm = 0.025 m

First we calculate the Fg:

Fg={(6.67*10^-11)*0.01*0.02}/(0.025²)=2.1344*10^-11 N

To get the velocity v of the pencil:

v²=2as, where a is the acceleration of the pencil and s is the path. In our case s=r so we can write:

v²=2ar

a=Fg/m₁= 2.133*10^-9 m/s²

v²=2*(2.133*10^-9)*0.025=1.0665*10^-10

v=√(1.0665*10^-10)=1.0327*10^-5 m/s

We have the velocity and the acceleration, so we can calculate the time t with the equation:

t=v/a=(1.0327*10^-5)/(2.133*10^-9)=4841.6 s

1 hour has 3600 s so when we divide time t in seconds by 3600 we get time T in hours:

T=t/3600=4841.6/3600=1.3449 h. 

So the time for the pencil and eraser to touch is T=1.3449 hours. 

Also time T can be expressed like T= 1h and 20 mins and 41.64 s

Natural Forces Affecting the Driver In one or more complete sentences, explain how natural laws apply to the following scenarios: How does inertia affect a person who is not wearing a seatbelt during a collision? How does kinetic energy affect the stopping distance of a vehicle traveling at 30 mph compared to the same vehicle traveling at 60 mph? How does kinetic energy affect the stopping distance of a small vehicle compared to a large vehicle? Keeping in mind the kinetic energy of a moving vehicle, how can a driver best prepare to enter sharp curves in the roadway? Using information about natural laws, explain why some car crashes produce minor injuries and others produce catastrophic injuries. Signs, Signals, and Pavement Markings Imagine you are taking a road trip! Select a destination and navigate the trip. Answer the following questions in one or more complete sentences: Where will you go on your trip? You approach a railroad crossing with a cross buck sign that has no lights or gates. What should you do? You arrive at an intersection with traffic lights that are not working because of a power outage. What do you do? There is a flashing yellow light at the intersection you are approaching. What does the flashing yellow light indicate, and what should you do to safely navigate this intersection? On the road you are traveling, the pavement markings change from broken white lines to solid white lines between the lanes of traffic. What does the line change mean? After an hour on the expressway, your passengers need to use the restroom and they want to get some food. As you approach the next exit, what color sign will you look for, and what type of information would you expect to see on that sign? When you take the exit ramp off the expressway and merge onto the next road, you see yellow lines dividing the roadway. What do the yellow lines tell you about the traffic flow?

[ad_1]

Natural Forces Affecting the Driver:

1. While the car stops, the person continues moving the way that the car were moving and then hits the obstacle in the car or the person can be thrown out of the vehicle. If the person wears belt, he will stop moving with the vehicle and won’t hit the obstacle.

2. We count approximate kinetic energy using the formula K = v^2. So the vehicle which is moving at 30 mph will have four times less kinetic energy than vehicle which is moving at 60 mph. If they have the same road conditions, the breaking distance will be four times as great for the car moving twice as fast.

3. Kinetic energy depends on object’s mass and velocity and it has direct relationship with the stopping distance. The lesser mass of the vehicle = the lesser kinetic energy and lesser stopping distance. => If both vehicles have the same velocity, then small vehicle has lesser kinetic energy than large vehicle.

4. We know that kinetic energy has this relationship with velocity K = v^2. So the best way to prepare to enter sharp curves in the roadway is to lower the speed. The most appropriate speed is 20-30 mph, but it depends on road conditions and car’s breaks condition.

5. Car crashes can happen with everyone so the best way is to be prepared. First the driver should wear a seatbelt while he’s driving. He should check his tires and breaks condition regularly. And also it’s important to slow down the vehicle while entering sharp curves. Without following these rules, the driver can get catastrophic injuries in a car crash.

Signs, Signals, and Pavement Markings: 

1. It doesn’t matter where you go. All you need is to learn highway code. It’s very different to know the meanings of every road sign. Also, it’s necessary to check your car’s conditions and you should take some spare parts for your car in case of accidents. So wherever you go, it’s important to be prepared.

2. You should stop before crossing and take few minutes to make sure there is no train approaching. If there is no train approaching, you can pass a railroad crossing. If you see approaching train, you should wait until it will pass a railroad crossing.

3. You should stop before the lights and wait to check the traffic movement and signs. Make sure that everything is safe and pass the intersection. Don’t move fast to avoid accidents.

4. Flashing yellow light means that it’s not necessary to stop but you should to pay attention on the traffic movement. So it would be better to yield before the lights and make sure if it’s safe to move. After that you can cross the intersection.

5. The line change means that the lane changes and you can’t cross solid lines. Pay more attention on road marking because it shows how you should behave on the road or highway.

6. As you approach the next exit and  your passengers need to use the restroom and get some food, you should look for green signs which indicate food and rest stops. You should to slow down if you don’t want to skip the sign.

7. When you take the exit ramp off the expressway and merge onto the next road, you see yellow lines dividing the roadway which indicates that there is oncoming traffic and this is a two-way highway.
