Answer:

Step-by-step explanation:

18). 3x + 2 ÷ 3x = [tex]\frac{2}{3x}[/tex]

Since, 3x + 2 ÷ 3x = 3x + [tex]\frac{2}{3x}[/tex]

Therefore, right hand side of the equation will be = 3x + [tex]\frac{2}{3x}[/tex]

20). [tex]\frac{4x+3}{3}=x+1[/tex]

Since, [tex]\frac{4x+3}{3}=\frac{4x}{3}+\frac{3}{3}[/tex]

= [tex]\frac{4}{3}x+1[/tex]

Therefore, right hand side of the equation should be [tex]\frac{4}{3}x+1[/tex].

Answer:

30%

Step-by-step explanation:

subtract the post-discount price from the pre-discount price

64.99 - 45.49 = 19.50

divide the answer by the original price

[tex]\frac{19.50}{64.99}[/tex] = 0.30

multiply the answer by 100

0.30 x 100 = 30%

to check:

take the original number and multiply it by the decimal form of the percentgae:

64.99 x 30% (0.30) = 19.50

take the answer and subtract it from the orginal answer

64.99 - 19.50 = 45.49

b. Write an equation that represents the cost of Carla’s cabs.

Answers

Answer:

a. y= 4 + 0.50x b. y= 1.00x

Step-by-step explanation:

Answer:

a. y = 0.5x +4 b. y = x

Step-by-step explanation:

a. Tom’s Taxis charges a fixed rate of $4 per ride plus $0.50 per mile.

m = $0.50 per mile

b = $4 per ride

y = 0.5x +4

b. Carla’s Cabs does not charge a fixed rate but charges $1.00 per mile.

m = $1 per mile

b = $0 per ride

y = x

I need help on this question someone please help. x/4=-12 (this says x divided by 2 equals -8). Explain how you would solve for x and what you would get. I’m in 7th grade so can someone make it easy to read like at the explaining part thanks.

Answers

So since our first example is X/4=-12 the first step would be to multiply 4 to both sides meaning you would multiply 4 by the division of 4 so it cancels out because they’re opposite operations do the same to the -12, so -12x4=-36 x=-36 the other example would be the same multiply 2 to both sides so on the left it would cancel out and on the right it would be -16 which is the answer to x
Hope this could help at least a little

What is the center and radius of the circle with the given equation x^2 + y^2 + 14x - 12y +69 = 0

Answers

Answer:

Center is (7,-6)

Our radius is 4

Step-by-step explanation:

Subtract 69 to both sides

Complete the square of the x terms and y terms.

[tex] {x}^{2} + 14x[/tex]

[tex] {y}^{2} - 12y[/tex]

(To complete the square divide the coefficient by 2 and square it).

[tex] (\frac{14}{2} ) {}^{2} = 49[/tex]

[tex]( \frac{ - 12}{2} ) {}^{2} = 36[/tex]

Add those terms to the full equation. Add 36 and 49 to the right side as well

[tex] {x}^{2} + 14x + 49 + {y}^{2} - 12y + 36 = 16[/tex]

Simplify the x and y terms into a binomial.

[tex](x + 7) {}^{2} + (y - 6) {}^{2} = 16[/tex]

Set the left side equal to zero separately to find the center and take the square root of the right side to find the radius.

[tex]x + 7 = 0[/tex]

[tex]x = - 7[/tex]

[tex]y - 6 = 0[/tex]

[tex]y = 6[/tex]

[tex]16 = {x}^{2} [/tex]

[tex]4 = x[/tex]

So our center is (-7,6)

Our radius is 4.

TRIGONOMETRY

Answers

Answer:

11). x = 25.8°

12). x = 67.3°

Step-by-step explanation:

11). By using sine rule in the given triangle,

cos(x) = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]

cos(x) = [tex]\frac{27}{30}[/tex]

x = [tex]\text{cos}^{-1}(\frac{9}{10} )[/tex]

x = 25.84

x ≈ 25.8°

12). By applying tangent rule in the given triangle,

tan(x) = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]

tan(x) = [tex]\frac{43}{18}[/tex]

x = [tex]\text{tan}^{-1}(\frac{43}{18} )[/tex]

x = 67.29°

x ≈ 67.3°

Find the surface area of the composite figure.

Answers

Answer:

644 cm³

Step-by-step explanation:

Surface area of the composite figure = (surface area of the upper cuboid - base area of upper cuboid) + (surface area of the lower cuboid - base area of the upper cuboid)

✔️Surface area of upper cuboid = 2(LW + LH + WH)

L = 3

W = 3

H = 8

Surface area of upper cuboid = 2(3*3 + 3*8 + 3*8) = 2(9 + 24 + 24) = 114 cm²

✔️Surface area of Surface area of lower cuboid = 2(LW + LH + WH)

L = 12

W = 10

H = 7

Surface area of lower cuboid = 2(12*10 + 12*7 + 10*7) = 2(120 + 84 + 70) = 548 cm²

✔️Base area of upper cuboid = L*W

L = 3

W = 3

Base area = 3*3 = 9 cm²

✅Surface area of the composite figure = (114 - 9) + (548 - 9) = 105 + 539 = 644 cm³

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 grandmothers birthday party and visits her to apologize.How does this incident provoke Trace to make a decision?He doesn't want to admit that he missed the party on purpose.It forces him to admit his anger at his grandfather.He wants a reason to ask about his parents.It forces him to lie to his grandmother to conceal who he really is.
