Michael is saving to buy his senior ring. The base cost of the ring is $280. There are also upgrades he can purchase for the ring. If he saves $35 each month, Which solution represents how many months it will take Micheal before he can purchase his ring?

A.x<_8
B.x_>8
C.x<8
D.x>8

Answers

Answer:

Step-by-step explanation:

Assuming that he doesn't buy any upgrades it will take 280/35 = 8 months to save enough money to buy the ring. Taking the possibility that he may buy an upgrade too we can say that it will take 8 months or more to buy the ring.

""solve triangle ABC using the given information round triangle measures to the nearest degree and side measure to the nearest tenth

Answers

9514 1404 393

Answer:

a) A = 73°, C = 59°, a = 16.7

b) A = 11°, C = 121°, a = 3.3

Step-by-step explanation:

The Law of Sines can be used to find angle C. Then the sum of angles in the triangle can be used to find angle A. The length of 'a' can be found either from the Law of Sines or the Law of Cosines at that point.

The given angle is opposite the shorter of the two given sides, so there are two possible solutions.

Acute triangle solution

The Law of Sines gives the relation ...

sin(C)/c = sin(B)/b

sin(C) = (c/b)sin(B)

C = arcsin(c/b·sin(B)) = arcsin(15/13·sin(48°)) ≈ 59°

Then angle A is 132° -59° = 73°, and side 'a' is ...

a = 13·sin(A)/sin(B) = 13·sin(73°)/sin(48°) ≈ 16.7

Obtuse triangle solution

The other value of arcsin(15/13·sin(48°)) is used:

C ≈ 121° ⇒ A = 11°

a = 13·sin(11°)/sin(48°) ≈ 3.3

The two solutions are ...

A = 73°, C = 59°, a = 16.7

A = 11°, C = 121°, a = 3.3

We note that the drawing is of an acute triangle, so that solution may be the one that is preferred.

In the above presentation, we have rounded angle values to the precision required by the problem statement (nearest degree). However, in the actual calculations, we have used the full calculator precision. Only the final answers have been rounded.

how do I solve for x for number 4

Answers

Answer: 20.8

Step-by-step explanation:

Since it is an equilateral triangle, we know the bottom is also 24. We also know that line E is bisecting the base. So using the smaller right triangle we know that the hypotenuse is 24 and one leg is 12. So use the Pythagorean theorem.

[tex]a^{2} +b^{2} =c^{2} \\12^{2} +b^{2} =24^{2} \\144+b^{2} =576\\b^{2} = 432\\b= 20.8[/tex]

Then, in 1822, he reversed his position. Some of Champollion's rivals suggested that he had gotten the idea from Thomas Young's Encyclopedia Britannica article. There the English scholar explained how the hieroglyphs in Ptolemy's name stood for sounds. Champollion hotly denied these suggestions, claiming that he had arrived at his new position entirely on his own." Please Help!

Read the novel excerpt.Superhero 101: A Family SecretTrace knew he would have to try to explain to his grandmother why he had missed her birthday party. He was dreading the conversation and the lie that he would inevitably have to tell. He thought telling her the truth would only open a Pandoras box. He rang the doorbell, and his grandmother answered right away, like she had been waiting for him. He had called and told her he would try to come by sometime that day, but he had not given her a precise time.She greeted him warmly, and he followed her into the kitchen where she had her customary jar of fresh-baked cookies ready for his indulgence. His grandmother was endearingly predictable. She had a daily routine and rarely deviated from it. Trace thought that given her lifestyle and penchant for routine and order, there was no way she would ever understand his life as Beetleman. He hated that he had no choice but to lie to his grandmother, whom he loved so much.They sat at the kitchen table. His grandmother poured him an ice-cold glass of milk and filled a plate with her delicious chocolate chip cookies. Before he had a chance to apologize, his grandmother spoke. Trace, Im glad you called and came by today. I know youre upset about missing my birthday party, but before you say anything about it, there is something I want to show you, she said.She went to a drawer and retrieved what appeared to be a large bracelet cuff made of silver. She handed it to Trace. He looked at it carefully. His grandmother moved his hands and pointed to something inscribed on the inside of the bracelet. Look at this. It's what I wanted you to see, she said as Trace read the words Family First. His heart sank when he read those words and recounted all the times that he had to sacrifice time with his family for his secret life.His grandmother noticed his dejected expression. Trace, I didnt show you this to make you feel bad about your choices. I know that they arent always yours to make. This cuff belonged to your grandfather. He had those words inscribed because they are what kept him going and allowed him to make those same tough choices.Trace stared at this grandmother. What was she saying? His grandfather was a superhero too?She continued, Your grandfather loved helping people, just like you do. Thats where you got your giftfrom him. Many times he had to miss family parties and outings because of his calling. But I always knew he did it for usfamily first.Trace was astounded. Hed had no idea that his grandfather was a superhero; now he realized that he no longer had to lie to his grandmother. His parents had died when he was very young, and his grandparents had raised him. He recalled his grandfather missing his 10th birthday party and how upset and angry he had been at his grandfather. He had cried himself to sleep that night, wrongly thinking that he was not important to his grandfather.Trace looked at the bracelet carefully, realizing that to him, it was as precious as the Hope diamond. He glanced up at his grandmother. His love for his family was his kryptonite, his grandmother continued. The only time he was weak was when you or I were in danger. He couldnt bear the thought of anything happening to us after what happened to your parents.In Superhero 101: A Family Secret, Trace misses his grandmother's birthday party and visits her to apologize.How does this incident provoke Trace's grandmother to make a decision?She shows Trace the bracelet and reveals that his grandfather was a superhero.She insists that Trace follow in his grandfathers footsteps and adopt his motto.She wonders if Trace wants to continue to be a superhero like his grandfather.She reveals the truth about his parents' deaths.
