Answer 1

Use the note that Linear pairs have sum 180°

TD is a straight line

[tex]\\ \rm\rightarrowtail m\overset{\frown}{CD}+122=180[/tex]

[tex]\\ \rm\rightarrowtail m\overset{\frown}{CD}=180-122=58°[/tex]

Now

DB arc be x

A whole angle is 360° or 2π

[tex]\\ \rm\rightarrowtail x+122+58+90=360[/tex]

[tex]\\ \rm\rightarrowtail x+270=360[/tex]

[tex]\\ \rm\rightarrowtail m\overset{\frown}{DB}=90°[/tex]

Answer:

your x point is 2

Then, to help you for y=2x just make a table of values

So for y=2(1) y=2, y=2(2) y=4, y= 2(3) y=6

So theres 3 points to start which gives you a hint that each point goes up two times. (0,0) (1,2) (2,4) (3,6)

From the picture attached you can the y intercept is (2,4)

Answer:

[tex]x=114[/tex]

Step-by-step explanation:

Since we know that a straight line is 180°, and we know that one of the angles is 66°, we can write a simple equation to figure this out: [tex]x+66=180[/tex] Then, to solve the equation all you would need to do is subtract [tex]66[/tex] from both sides to get [tex]x=114[/tex].

Step-by-step explanation:

n the card game The Dragons of Castlenook, players score points based on the cards they have at the end of the game. Before playing, Reagan randomly selects 13 cards from the 80-card deck and gets 5 dragons, 1 cyclops, 4 ogres, and 3 centaurs. Based on the data, estimate how many ogre cards are in the deck.

Answers

Using proportions, it is found that the estimate of the number of ogre cards in the deck is of 24.6.

What is a proportion?

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

In this problem, out of 13 cards, 4 are ogres. How many are ogres out of 80? The rule of three is given by:

13 cards - 4 ogres.

80 cards - x ogres.

Applying cross multiplication:

13x = 320.

x = 320/13

x = 24.6.

The estimate of the number of ogre cards in the deck is of 24.6.

How do you find the length of AC? Picture below

Answers

Answer:

12cm

Step-by-step explanation:

this is a right angle triangle

so taking 'b' as base, 'a' as perpendicular and 'c' is hypotenuse which is equal to 13cm

and 1 angle is given which 22.6 degrees

and we need to find out 'b' which is AC

so we have

sin(x)= perpendicular/hypotenuse

cos(x)= base/hypotenuse

tan(x)=perpendicular/base

cos(22.6) = base/hypotenuse=13

cos(22.6)*13 = base

0.9232*13 = base

base = 12cm

A store sells two brands of applesauce.
Which brand provides more servings?
brand A: 24 1/2 ounces 2/3 cup per serving
brand B: 30 2/3 ounces 3/4 cup per serving
Alternative text
A.
Brand A because it provides 4 19/32 servings.
B.
Brand A because it provides 16 1/3 servings.
C.
Brand B because it provides 5 1/9 servings.
D.
Brand B because it provides 23 servings.

Answers

This problem is a dog of a bear because of the units.

It tells us how many ounces are in a jar, but how many cups are in a serving.

So in order to figure out how many servings are in a jar, we have to either change the jar from ounces to cups, or else change the serving from cups to ounces.

And of course, in order to do either of those things, we need to know how many ounces make 1 cup ! Hint: 1 cup = 8 ounces .

AND PLUS trying to work with all the fractions is gonna be ridiculous too.

Jar-A: (24 1/2 ounces) / (8 ounces/cup) = 3 1/16 cups

How many servings is that ?

(3 1/16 cups) / (2/3 cup/serving) = 4 19/32 servings

Jar-B: (30 2/3 ounces) / (8 ounces/cup) = 3 5/6 cups

How many servings is that ?

(3 5/6 cups) / (3/4 cup/serving) = 5 1/9 servings

(5 1/9) is more than (4 19/32). So Jar-B provides more servings than Jar-A.

Choice - C

Note: Both brands are great for people who are on a diet, because they have to work off so many calories working out the stupid fractions, and it takes so long that they never get around to eating the applesauce.

Answer:

ar-B provides more servings than Jar-A. Choice - C

Can the sides of a triangle have lengths 7.6, 2.5, and 2.2?

Answers

Answer:

No.

Step-by-step explanation:

Given the following question:

[tex]7.6, 2.5, 2.2[/tex]

In order for any given sides to form a triangle it has to pass the triangle inequality theorem, which is the sum of any two given sides of the triangle has to be greater than the third side in order for it to be a triangle.

In this case...
[tex]7.6, 2.5, 2.2[/tex]
[tex]7.6 + 2.5 = 10.1[/tex]
[tex]10.1 > 2.2[/tex]

[tex]2.5+2.2=4.7[/tex]
[tex]4.7 < 7.6[/tex]

[tex]7.6 +2.2=9.8[/tex]
[tex]9.8 > 7.8[/tex]

Therefore, your answer is "no" the following sides do not form a triangle.

he greatest common factor of 7x^4y^2 - 12x^3y^3 is the greatest number that can divided both terms of the expression

The greatest common factor of 7x^4y^2 - 12x^3y^3 is x^3y^2

How to identify the greatest common factor

The expression is given as:

7x^4y^2 - 12x^3y^3

Factor out x^3

x^3(7xy^2 - 12y^3)

Factor out y^2

x^3y^2(7x - 12y)

The first factor of the expression represents the greatest common factor of 7x^4y^2 - 12x^3y^3

Hence, the greatest common factor of 7x^4y^2 - 12x^3y^3 is x^3y^2

A segment has one endpoint at the origin O and the other endpoint at A(12,36). If point B is located on OA such that OA/BA=3 then which of the following are the coordinates of B?
(1) (4,12) (2) (9,27) (3) (8,24) (4) (36,108)

Answers

The distance between (8, 24) and (12, 36) is one-third of the distance between (0, 0) and (12, 36).

How to find the coordinates of point B?

We know that:

O = (0, 0)A = (12, 36).

And point B is between these two, such that:

OA/BA = 3

Meaning, OA is 3 times BA.

Now, if we apply a factor of 1/3 to point A, we get:

(12/3, 36/3) = (4, 12)

So, the distance between A and B is equal to the distance between the origin and (4, 12) (a change of 4 units in the x-component and 12 units in the y-component).

The point that meets that condition is (8, 24), which is given by multiplying by 2 the previous coordinates.

The distance between (8, 24) and (12, 36) is one-third of the distance between (0, 0) and (12, 36).

PENN FOSTERWRITTEN COMMUNICATION: PERSONAL NARRATIVE ESSAYThe Hospital I never realized how much I could lose until I stood in a hospital room with my dad lying in the bed. I can recall to the years prior, where I would sit and ponder about loss. Most people think they can predict the worst moments in their life. Even I thought so for a while, but I dont think I could have ever predicted this. I couldnt sleep that night. I went to bed at three in the morning, but I was quickly woken up two hours later by my grandmother slamming open the front door to my house. The sound made my eyes fly open and I could feel how hard my heart was pounding. She slung my bedroom door open and flipped the switch. Her loud voice echoed in my ears, Get up! Im taking you to the hospital! I scrambled to find my shoes. I wasnt worried about anything but getting to the hospital. I wanted to maintain my composure, but I knew he was dying. When I got to the hospital, I saw my dad laying on hospital bed. It was hard to see him unconscious with tubes poking out of him, but I had to be strong. This was the last time I was ever going to see him alive. My thoughts ran as I stood in the room. I saw the way my brother was crying, my mother was trying to comfort him, and the hospital staff was trying to comfort us with food and drinks. I thought maybe I wouldve been better off just laying in bed at this time and getting the news as a text messages, but I dont think this wouldve been easier either way. I went to the entrance of the hospital to show one of my family members where my dads room was. When I walked back up, I saw a crowd of nurses and doctors trying to resuscitate him. A couple of them were shouting commands while a woman pumped his chest. My family was taken into a waiting room because my dad coded. One of the nurses took me and my family member to a room where my mom and brother were. I dont think that I could have ever prepared myself for witnessing that. After what seemed like hours, a nurse directed us to the room where my dad was. The monitors were off, the tubes were gone, and so was he. I expected it and all I could do was stare at him. I felt heartless, because my brother was uncontrollably sobbing and screaming. Only if I knew what life would be like after losing him.
