7. We Learned That In A Plane, Two Lines Perpendicular To The Same Line Are Parallel. Use The Rectangular

Answers

Answer 1

Answer:

"In a plane" imposes the condition that these 3 lines exist in ONLY 2 dimensions, otherwise, the statement, "Two lines perpendicular to the same line are parallel" is false.

Example 1: lines CE & DF are // & perpendicular to CD. TRUE

Example 2: lines CE & BD are // & perpendicular to CD. FALSE

is $3 and the cost of one soda is $2 but James only has $15 to spend. Write and
equation to represent this situation. Remember to define the variables!
2. If James buys 3 boxes of popcorn how many sodas can he buy?

Answers

Answer:

1.) 15-3-2=x

2.) He can buy 3 sodas

Step-by-step explanation:

1.) 15 is how much he has, -3 is the price of the popcorn, -2is the price of the soda. =x is what needs to be solved in the equation (its 10 if you need the answer)

2.) He can buy 3 sodas because 3 boxes of popcorn is $9 since one box is $3,  he has $15 you take away $9 and you are left with $6 and 6 divided by 2 is 3.

Last year, 320 students were members of Pine Hill Middle School clubs. This year, there was a 20% increase in memberships. How many students are members this year?

Answers

Answer:

384

Step-by-step explanation:

No. of students in the club last year = 320

No. of students in the club this year increased by 20%

To find the actual increase, 20% is multiplied by the number of students in the club last year which is 320 and to find the number of students in the club this year add the answer to 320 (the number of students in the club last year)

That is,

= 20% * 320

= 20/100 * 320

= 64

Finding the number of students in the club this year

320 + 64 = 384 students

NOTE : Increase means addition that is why the number of students in the club last year is added to the actual increase

Let x represent the number of 20-cent increases in the cost of a package of strawberries.

Answers

Answer:

-1.8x² - 1.61x - 37.45 > 0

Step-by-step explanation:

Pattie's Produce charges $2.29 for a package of strawberries. On average, Pattie's Produce sells 95 packages of strawberries daily. They estimate that for each 20-cent increase in the cost of a package of strawberries, 9 less packages will be sold each day. Let x represent the number of 20-cent increases in the cost of a package of strawberries. Which inequality represents the values of x that would allow Pattie's Produce to have a daily revenue of at least $255 from selling the packages of strawberries?

Answer:

The cost of packaging 95 packages of strawberries is $2.29(95)=$217.55.

20-cent increase in the cost of a package of strawberries leads to 9 less packages to be sold. If x represent the number of 20-cent increases in the cost of a package of strawberries. the cost of packaging is:

Cost = (2.29 + 0.2x)(95 - 9x)

For a revenue of atleast $255:

(2.29 + 0.2x)(95 - 9x) > 255

217.55 - 20.61x + 19x - 1.8x² > 255

-1.8x² - 1.61x + 217.55 > 255

-1.8x² - 1.61x + 217.55 - 255 > 0

-1.8x² - 1.61x - 37.45 > 0

What is 3x+7x=9-18? Math is confusing once you get into 7th grade.

Answers

Answer:

x-(-0.9)

Step-by-step explanation:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation::3*x+7*x-(9-18)=0

Solve::10x+9 = 0

Subtract 9 from both sides of the equation::10x = -9

Divide both sides of the equation by 10::x = -9/10 = -0.900

Answer:

x = -0.9

Step-by-step explanation:

3x+7x=9-18

10x = -9

x = -9 / 10

x = -0.9

Two owners of a cattle ranch, Jo and Val, want to find the average weight for the ranch's 200 cows. Instead of weighing all of the cows: Jo weighs 25 cows and gets an average weight of 1,350 pounds (stdev 50) Val weighs 100 cows and gets an average weight of 1,420 pounds (stdev 50) What is Jo's margin of error, rounded to the nearest whole number? (The formula is 1.96 straight x left parenthesis StdDev right parenthesis divided by square root of straight N)

Answers

Answer:

The  value  is [tex]E =19.6 [/tex]

Step-by-step explanation:

From the question we are told that

  The mean of Jo  cows is  [tex]\= x_1 = 1350[/tex]

  The standard deviation of Jo cow is  [tex]s_1 =  50[/tex]

  The mean of Val  cows is [tex]\= x_2  = 1420 [/tex]

   The standard deviation of Val  cows  is  [tex]s_2 =  50[/tex]

    The sample size for both Val  and  Jo  is  n = 25

Let assume that the level of significance is  [tex]\alpha = 0.05[/tex]

Generally from the normal distribution table the critical value  of  [tex]\frac{\alpha }{2}[/tex] is  

   [tex]Z_{\frac{\alpha }{2} } =  1.96[/tex]

Generally the margin of error is mathematically represented as  

      [tex]E = Z_{\frac{\alpha }{2} } *  \frac{\sigma }{\sqrt{n} }[/tex]

Hence margin of error for Jo is  

=>   [tex]E = 1.96 *  \frac{50}{\sqrt{25} }[/tex]

=>   [tex]E =19.6 [/tex]

(11x - 1)

151°

Answers

Answer:

x= 1.6 degrees

Step-by-step explanation:

to find the missing angle 180 degrees - 151 degrees

29° is the missing angle at the bottom ryt of the triangle.

all angles in triangle add upto 180°

so, 20x-3°+11x-1°+29°= 180°

31x=180°-25°

x= 1.6°

A polygon with three edges and three vertices is called a triangle.

x=1.6° is its value.

Explain about the triangle?

Based on the lengths of its sides, triangles can be categorized into one of three groups: Scalene. Isosceles. Equilateral.

The trigon, a 3-sided polygon, is sometimes (though not often) referred to as a triangle. Every triangle has three sides and three angles, some of which might be the same.

The triangle's angles are created by joining its three sides end to end at a single point. The sum of the three angles of the triangle is 180degrees.

To identify the omitted angle between 180 and 151 degrees

The triangle's bottom right corner lacks a 29° angle.

triangle's angles sum up to 180°

so, 20x-3°+11x-1°+29°= 180°

31x=180°-25°

x =1.6 degree

This quote is important because it Read the excerpt from the play Apple Picking:Characters:- Mischa- Luke- Mom- DadScene OneOn an overcast autumn afternoon in the middle of a field with many apple trees. A brother and a sister have a ladder up against an apple tree. One is picking apples and placing them in a sack tied around her waist. The other is holding the ladder steady.Mischa: (standing on the ladder and looking at an apple) I'm not so sure about these. They have a ton of spots and are not quite ripe.Luke: That's alright, we're just making a pie for Sunday dinner anyway. No one will see the spots, and we can add sugar to sweeten them up.Mischa: (Nodding in approval) Yeah, I guess you're right. Mom always likes her pie apples to be a little firm anyways.Suddenly, the wind begins to blow strongly making the ladder tip back and forth slightly.Mischa: (With an alarmed look on her face.) What's going on? There isn't supposed to be a storm today! We'll never make it back to our house before it hits!Luke: (Holding onto the ladder as hard as he can) You need to come down! I can't hold the ladder much longer!Mischa carefully but swiftly climbs down the ladder while the wind is still blowing. Luke holds on to the ladder as it sways back and forth. Mischa makes it to the bottom. They both look toward dark clouds rolling in quickly with thunder and lightning.Luke: (Yelling over the storm) We'd better find some shelter! (Pointing toward a rundown old farmhouse.) I think there's an old farm house that way!Mischa: (Also yelling) You lead the way. I'm too scared!Luke: (Grabbing her by the hand) It's going to be okay! Run with me!Both children run to the old farmhouse holding each other's hand. When they make it there, they enter through an open window.Scene TwoIn the kitchen of the old farmhouse. There is an old dusty table and chairs, but everything else including the stove is gone. The windows are broken, the curtains tattered, and the wallpaper peeling. The wind is picking up and blowing through. The children are calming down. Mischa looks out the broken window where a large dead tree sits close to the house, while Luke sits at the old table. The sack of apples sits on the table.Mischa: It's almost here Luke. The branches on the trees are swaying all over the place.Luke: (Looking at the old tree through the window) Come away from the window Mischa. It's a really bad storm, that's for sure.Mischa: (sitting down in the chair opposite Luke.) I think it's a tornado.Luke: It's not a tornado, but those are some heavy winds.The wind picks up and the curtains sway violently. Something smacks up against the side of the house.Luke: What was that? It's picking up.Mischa: Where are Mom and Dad? Why aren't they here to help us?Luke: Never mind that. We need to worry about ourselves right now. I think we should go down to the ...Suddenly, a tree branch hits the window smashing it even more than it was. Luke and Mischa scream.Mischa: (Yelling) To the basement!The children run toward the basement when Mischa stops and turns back.Luke: (Still yelling) What are you doing? Come back!Mischa: (Still yelling) The apples! I need to grab the apples!Luke: Mischa no!Mischa runs to grab the apples. She gets a hold of the sack and turns around toward the basement again.
