what would the class size be if 30 people represent 40% of the class?

Answers

Answer 1

Answer:

110 students

Step-by-step explanation:

%40 Divide 30

30 divided by %40 is 0.75

SO there is 60% left

%60 divided by 0.75

That is 80

80 + 30 =

110

Nolan invested $5,300 in an account paying an interest rate of 3.8% compounded
annually. Assuming no deposits or withdrawals are made, how long would it take, to
the nearest tenth of a year, for the value of the account to reach $6,880?
HELP

Answers

Answer:

7

Step-by-step explanation:

did the question

The amount of money would be $6,880 in the account after 7 years.

What is Compound interest?

Compound interest is defined as interest paid on the original principal and the interest earned on the interest of the principal.

A = P(1+r/100)ⁿ

Where:

A = the future value of the investment or loan

P = the principal investment or loan amount

r = the interest rate (decimal)

n = the number of compound periods

Given data as follows:

p = $5,300

r = 3.8%

A = $6,880

A = P(1+r/100)ⁿ

Substitute the values of p,r, and A in the formula,

6,880 = 5,300(1 + 3.8/100)ⁿ

6,880/5,300 = (1 + 0.038)ⁿ

1.2981 = (1.038)ⁿ

n = 6.9954

Rounded to the nearest digit, and we get

n = 7

Therefore, the amount of money would be $6,880 in the account after 7 years.

how do i solve this and what is the answer?

Answers

Answer:

I totally get why you are asking , how do I solve this.  there is so much implied about this

Step-by-step explanation:

1st you have to recognize that ∠ACB ( in my drawing ) has that same angle as the arc from A to B  ,  so that's implied.   next you have to recognize that the triangle formed by ACB with the 124 degree angle at C is an isosceles and therefore has identical angles at A and B  so that's  180 = 124 + 2A  , so A = 28° and so does B , then , b/c we know that small angle... you also have to know, that the line AC is perpendicular to AD.  that they from a right angle and there for... you now know , that ∠BAD is the other part of that 90 or 90= 28 + ∠BAD so  ∠BAD = 62°

I went through that kinda fast, there was several "leaps" of using logic to get to the correct answer , using things you know from prior understanding about angles , circles  and geometry,  you are putting all of the parts together here.  :/  kinda daunting in some ways.

Answers

Answer:

500 families

Step-by-step explanation:

We want to estimate the size of the dark blue section of the chart. The chart looks like the left of the pie chart is split evenly with the dark blue section. So we estimate that each of those must represent 12 or 50% of the total number of families. Therefore,

0.50⋅1000=500

Given g(x)=-2x+2, solve for x when g(x)=8

Answers

Answer:

x=±3. Explanation: g(x)=2x2−10 g(x)=8. ie 2x2−10=8 2x2=18 x2=9 x=±3.

Step-by-step explanation:

x = -3
To solve this, first set -2x + 2 = 8

Now you want to try to get x alone on one side so subtract 2 on both sides
-2x = 6

Finally divide both sides by -2 to find out what x is equal to

x =-3

To check if this is the right answer, plug -3 in for x in the original equation and see if it comes out as 8

-2(-3) + 2 = 8
6 + 2 = 8
8 = 8

Both sides are equal so -3 is the solution

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.Question 1Part AWhat is an allusion in "Superhero 101: A Family Secret"?the scene in which Trace's grandmother notices he is sadthe reference to the motto "Family First"the reference to the grandfather's love and kryptonitethe scene in which Trace cries himself to sleepQuestion 2Part BHow does the allusion in Part A affect the meaning of the story?It reminds readers that family is the most important thing..It discloses to readers that Traces parents died mysteriously.It shows readers that Trace is not a person of integrity and honesty.It reveals to readers Traces grandfathers biggest weakness.
